RecognizerIntent

ACTION_GET_LANGUAGE_DETAILS

static val ACTION_GET_LANGUAGE_DETAILS: String

A broadcast intent which can be fired to the BroadcastReceiver component specified in the meta-data defined in the DETAILS_META_DATA meta-data of an Activity satisfying ACTION_WEB_SEARCH.

When fired with Context#sendOrderedBroadcast(Intent, String, BroadcastReceiver, android.os.Handler, int, String, android.os.Bundle), a Bundle of extras will be returned to the provided result receiver, and should ideally contain values for EXTRA_LANGUAGE_PREFERENCE and EXTRA_SUPPORTED_LANGUAGES.

(Whether these are actually provided is up to the particular implementation. It is recommended that Activitys implementing ACTION_WEB_SEARCH provide this information, but it is not required.)

Value: "android.speech.action.GET_LANGUAGE_DETAILS"

ACTION_RECOGNIZE_SPEECH

static val ACTION_RECOGNIZE_SPEECH: String

Starts an activity that will prompt the user for speech and send it through a speech recognizer. The results will be returned via activity results (in android.app.Activity#onActivityResult, if you start the intent using Activity#startActivityForResult(Intent, int)), or forwarded via a PendingIntent if one is provided.

Starting this intent with just android.app.Activity#startActivity(android.content.Intent) is not supported. You must either use Activity#startActivityForResult(Intent, int), or provide a PendingIntent, to receive recognition results.

The implementation of this API is likely to stream audio to remote servers to perform speech recognition which can use a substantial amount of bandwidth.

Required extras:

• EXTRA_LANGUAGE_MODEL

Optional extras:

• EXTRA_PROMPT
• EXTRA_LANGUAGE
• EXTRA_MAX_RESULTS
• EXTRA_RESULTS_PENDINGINTENT
• EXTRA_RESULTS_PENDINGINTENT_BUNDLE

Result extras (returned in the result, not to be specified in the request):

• EXTRA_RESULTS

NOTE: There may not be any applications installed to handle this action, so you should make sure to catch ActivityNotFoundException.

Value: "android.speech.action.RECOGNIZE_SPEECH"

ACTION_VOICE_SEARCH_HANDS_FREE

static val ACTION_VOICE_SEARCH_HANDS_FREE: String

Starts an activity that will prompt the user for speech without requiring the user's visual attention or touch input. It will send it through a speech recognizer, and either synthesize speech for a web search result or trigger another type of action based on the user's speech. This activity may be launched while device is locked in a secure mode. Special care must be taken to ensure that the voice actions that are performed while hands free cannot compromise the device's security. The activity should check the value of the EXTRA_SECURE extra to determine whether the device has been securely locked. If so, the activity should either restrict the set of voice actions that are permitted or require some form of secure authentication before proceeding. To ensure that the activity's user interface is visible while the lock screen is showing, the activity should set the android.view.WindowManager.LayoutParams#FLAG_SHOW_WHEN_LOCKED window flag. Otherwise the activity's user interface may be hidden by the lock screen. The activity should take care not to leak private information when the device is securely locked.

Optional extras:

• EXTRA_SECURE

In some cases, a matching Activity may not exist, so ensure you safeguard against this.

Value: "android.speech.action.VOICE_SEARCH_HANDS_FREE"

ACTION_WEB_SEARCH

static val ACTION_WEB_SEARCH: String

Starts an activity that will prompt the user for speech, send it through a speech recognizer, and either display a web search result or trigger another type of action based on the user's speech.

If you want to avoid triggering any type of action besides web search, you can use the EXTRA_WEB_SEARCH_ONLY extra.

Required extras:

• EXTRA_LANGUAGE_MODEL

Optional extras:

• EXTRA_PROMPT
• EXTRA_LANGUAGE
• EXTRA_MAX_RESULTS
• EXTRA_PARTIAL_RESULTS
• EXTRA_WEB_SEARCH_ONLY
• EXTRA_ORIGIN

Result extras (returned in the result, not to be specified in the request):

• EXTRA_RESULTS
• EXTRA_CONFIDENCE_SCORES (optional)

NOTE: There may not be any applications installed to handle this action, so you should make sure to catch ActivityNotFoundException.

Value: "android.speech.action.WEB_SEARCH"

DETAILS_META_DATA

static val DETAILS_META_DATA: String

Meta-data name under which an Activity implementing ACTION_WEB_SEARCH can use to expose the class name of a BroadcastReceiver which can respond to request for more information, from any of the broadcast intents specified in this class.

Broadcast intents can be directed to the class name specified in the meta-data by creating an Intent, setting the component with Intent#setComponent(android.content.ComponentName), and using Context#sendOrderedBroadcast(Intent, String, BroadcastReceiver, android.os.Handler, int, String, android.os.Bundle) with another BroadcastReceiver which can receive the results.

The getVoiceDetailsIntent(android.content.Context) method is provided as a convenience to create a broadcast intent based on the value of this meta-data, if available.

This is optional and not all Activitys which implement ACTION_WEB_SEARCH are required to implement this. Thus retrieving this meta-data may be null.

Value: "android.speech.DETAILS"

EXTRA_AUDIO_INJECT_SOURCE

static val EXTRA_AUDIO_INJECT_SOURCE: String

Deprecated: Replaced with EXTRA_AUDIO_SOURCE

The extra key used in an intent which is providing an already opened audio source for the RecognitionService to use. Data should be a URI to an audio resource.

Depending on the recognizer implementation, this value may have no effect.

Value: "android.speech.extra.AUDIO_INJECT_SOURCE"

EXTRA_AUDIO_SOURCE

static val EXTRA_AUDIO_SOURCE: String

Optional android.os.ParcelFileDescriptor pointing to an already opened audio source for the recognizer to use. The caller of the recognizer is responsible for closing the audio. If this extra is not set or the recognizer does not support this feature, the recognizer will open the mic for audio and close it when the recognition is finished.

Along with this extra, please send EXTRA_AUDIO_SOURCE_CHANNEL_COUNT, EXTRA_AUDIO_SOURCE_ENCODING, and EXTRA_AUDIO_SOURCE_SAMPLING_RATE extras, otherwise the default values of these extras will be used.

Additionally, EXTRA_ENABLE_BIASING_DEVICE_CONTEXT may have no effect when this extra is set.

This can also be used as the string value for EXTRA_SEGMENTED_SESSION to enable segmented session mode. The audio must be passed in using this extra. The recognition session will end when and only when the audio is closed.

Value: "android.speech.extra.AUDIO_SOURCE"

EXTRA_AUDIO_SOURCE_CHANNEL_COUNT

static val EXTRA_AUDIO_SOURCE_CHANNEL_COUNT: String

Optional integer, to be used with EXTRA_AUDIO_SOURCE, to indicate the number of channels in the audio. The default value is 1.

Value: "android.speech.extra.AUDIO_SOURCE_CHANNEL_COUNT"

EXTRA_AUDIO_SOURCE_ENCODING

static val EXTRA_AUDIO_SOURCE_ENCODING: String

Optional integer (from android.media.AudioFormat), to be used with EXTRA_AUDIO_SOURCE, to indicate the audio encoding. The default value is android.media.AudioFormat#ENCODING_PCM_16BIT.

Value: "android.speech.extra.AUDIO_SOURCE_ENCODING"

EXTRA_AUDIO_SOURCE_SAMPLING_RATE

static val EXTRA_AUDIO_SOURCE_SAMPLING_RATE: String

Optional integer, to be used with EXTRA_AUDIO_SOURCE, to indicate the sampling rate of the audio. The default value is 16000.

Value: "android.speech.extra.AUDIO_SOURCE_SAMPLING_RATE"

EXTRA_BIASING_STRINGS

static val EXTRA_BIASING_STRINGS: String

Optional list of strings, towards which the recognizer should bias the recognition results. These are separate from the device context.

Value: "android.speech.extra.BIASING_STRINGS"

EXTRA_CALLING_PACKAGE

static val EXTRA_CALLING_PACKAGE: String

The extra key used in an intent to the speech recognizer for voice search. Not generally to be used by developers. The system search dialog uses this, for example, to set a calling package for identification by a voice search API. If this extra is set by anyone but the system process, it should be overridden by the voice search implementation.

Value: "calling_package"

EXTRA_CONFIDENCE_SCORES

static val EXTRA_CONFIDENCE_SCORES: String

A float array of confidence scores of the recognition results when performing ACTION_RECOGNIZE_SPEECH. The array should be the same size as the ArrayList returned in EXTRA_RESULTS, and should contain values ranging from 0.0 to 1.0, or -1 to represent an unavailable confidence score.

Confidence values close to 1.0 indicate high confidence (the speech recognizer is confident that the recognition result is correct), while values close to 0.0 indicate low confidence.

Returned in the results; not to be specified in the recognition request. This extra is optional and might not be provided. Only present when Activity#RESULT_OK is returned in an activity result.

Value: "android.speech.extra.CONFIDENCE_SCORES"

EXTRA_ENABLE_BIASING_DEVICE_CONTEXT

static val EXTRA_ENABLE_BIASING_DEVICE_CONTEXT: String

Optional boolean to enable biasing towards device context. The recognizer will use the device context to tune the recognition results.

Depending on the recognizer implementation, this value may have no effect.

Value: "android.speech.extra.ENABLE_BIASING_DEVICE_CONTEXT"

EXTRA_ENABLE_FORMATTING

static val EXTRA_ENABLE_FORMATTING: String

Optional string to enable text formatting (e.g. unspoken punctuation (examples: question mark, comma, period, etc.), capitalization, etc.) and specify the optimization strategy. If set, the partial and final result texts will be formatted. Each result list will contain two hypotheses in the order of 1) formatted text 2) raw text.

Depending on the recognizer implementation, this value may have no effect.

Value: "android.speech.extra.ENABLE_FORMATTING"

EXTRA_ENABLE_LANGUAGE_DETECTION

static val EXTRA_ENABLE_LANGUAGE_DETECTION: String

Optional boolean indicating whether to enable language detection. When enabled, the recognizer will consistently identify the language of the current spoken utterance and provide that info via RecognitionListener#onLanguageDetection(Bundle).

Depending on the recognizer implementation, this flag may have no effect.

Value: "android.speech.extra.ENABLE_LANGUAGE_DETECTION"

EXTRA_ENABLE_LANGUAGE_SWITCH

static val EXTRA_ENABLE_LANGUAGE_SWITCH: String

Optional string to enable automatic switching to the language being spoken with the desired sensitivity level, instead of being restricted to a single language. The corresponding language models must be downloaded to support the switch. Otherwise, the recognizer will report an error on a switch failure. The recognizer provides the switch results via RecognitionListener#onLanguageDetection(Bundle).

Since detection is a necessary requirement for the language switching, setting this value implicitly enables EXTRA_ENABLE_LANGUAGE_DETECTION.

Depending on the recognizer implementation, this value may have no effect.

Value: "android.speech.extra.ENABLE_LANGUAGE_SWITCH"

EXTRA_HIDE_PARTIAL_TRAILING_PUNCTUATION

static val EXTRA_HIDE_PARTIAL_TRAILING_PUNCTUATION: String

Optional boolean, to be used with EXTRA_ENABLE_FORMATTING, to prevent the recognizer adding punctuation after the last word of the partial results. The default is false.

Value: "android.speech.extra.HIDE_PARTIAL_TRAILING_PUNCTUATION"

EXTRA_LANGUAGE

static val EXTRA_LANGUAGE: String

Optional IETF language tag (as defined by BCP 47), for example "en-US". This tag informs the recognizer to perform speech recognition in a language different than the one set in the java.util.Locale#getDefault().

Value: "android.speech.extra.LANGUAGE"

EXTRA_LANGUAGE_DETECTION_ALLOWED_LANGUAGES

static val EXTRA_LANGUAGE_DETECTION_ALLOWED_LANGUAGES: String

Optional list of IETF language tags (as defined by BCP 47, e.g. "en-US", "de-DE"). This extra is to be used with EXTRA_ENABLE_LANGUAGE_DETECTION. If set, the recognizer will constrain the language detection output to this list of languages, potentially improving detection accuracy.

Value: "android.speech.extra.LANGUAGE_DETECTION_ALLOWED_LANGUAGES"

EXTRA_LANGUAGE_MODEL

static val EXTRA_LANGUAGE_MODEL: String

Informs the recognizer which speech model to prefer when performing ACTION_RECOGNIZE_SPEECH. The recognizer uses this information to fine tune the results. This extra is required. Activities implementing ACTION_RECOGNIZE_SPEECH may interpret the values as they see fit.

Value: "android.speech.extra.LANGUAGE_MODEL"

EXTRA_LANGUAGE_PREFERENCE

static val EXTRA_LANGUAGE_PREFERENCE: String

The key to the extra in the Bundle returned by ACTION_GET_LANGUAGE_DETAILS which is a String that represents the current language preference this user has specified - a locale string like "en-US".

Value: "android.speech.extra.LANGUAGE_PREFERENCE"

EXTRA_LANGUAGE_SWITCH_ALLOWED_LANGUAGES

static val EXTRA_LANGUAGE_SWITCH_ALLOWED_LANGUAGES: String

Optional list of IETF language tags (as defined by BCP 47, e.g. "en-US", "de-DE"). This extra is to be used with EXTRA_ENABLE_LANGUAGE_SWITCH. If set, the recognizer will apply the auto switch only to these languages, even if the speech models of other languages also exist. The corresponding language models must be downloaded to support the switch. Otherwise, the recognizer will report an error on a switch failure.

Value: "android.speech.extra.LANGUAGE_SWITCH_ALLOWED_LANGUAGES"

EXTRA_LANGUAGE_SWITCH_INITIAL_ACTIVE_DURATION_TIME_MILLIS

static val EXTRA_LANGUAGE_SWITCH_INITIAL_ACTIVE_DURATION_TIME_MILLIS: String

Optional integer to use for EXTRA_ENABLE_LANGUAGE_SWITCH. If set, the language switch will only be activated for this value of ms of audio since the START_OF_SPEECH. This could provide a more stable recognition result when the language switch is only required in the beginning of the session.

Depending on the recognizer implementation, this flag may have no effect.

Value: "android.speech.extra.LANGUAGE_SWITCH_INITIAL_ACTIVE_DURATION_TIME_MILLIS"

EXTRA_LANGUAGE_SWITCH_MAX_SWITCHES

static val EXTRA_LANGUAGE_SWITCH_MAX_SWITCHES: String

Optional integer to use for EXTRA_ENABLE_LANGUAGE_SWITCH. If set, the language switch will be deactivated when LANGUAGE_SWITCH_MAX_SWITCHES reached.

Value: "android.speech.extra.LANGUAGE_SWITCH_MAX_SWITCHES"

EXTRA_MASK_OFFENSIVE_WORDS

static val EXTRA_MASK_OFFENSIVE_WORDS: String

Optional boolean indicating whether the recognizer should mask the offensive words in recognition results. The Default is true.

Value: "android.speech.extra.MASK_OFFENSIVE_WORDS"

EXTRA_MAX_RESULTS

static val EXTRA_MAX_RESULTS: String

Optional limit on the maximum number of results to return. If omitted the recognizer will choose how many results to return. Must be an integer.

Value: "android.speech.extra.MAX_RESULTS"

EXTRA_ONLY_RETURN_LANGUAGE_PREFERENCE

static val EXTRA_ONLY_RETURN_LANGUAGE_PREFERENCE: String

Specify this boolean extra in a broadcast of ACTION_GET_LANGUAGE_DETAILS to indicate that only the current language preference is needed in the response. This avoids any additional computation if all you need is EXTRA_LANGUAGE_PREFERENCE in the response.

Value: "android.speech.extra.ONLY_RETURN_LANGUAGE_PREFERENCE"

EXTRA_ORIGIN

static val EXTRA_ORIGIN: String

Optional value which can be used to indicate the referer url of a page in which speech was requested. For example, a web browser may choose to provide this for uses of speech on a given page.

Value: "android.speech.extra.ORIGIN"

EXTRA_PARTIAL_RESULTS

static val EXTRA_PARTIAL_RESULTS: String

Optional boolean to indicate whether partial results should be returned by the recognizer as the user speaks (default is false). The server may ignore a request for partial results in some or all cases.

Value: "android.speech.extra.PARTIAL_RESULTS"

EXTRA_PREFER_OFFLINE

static val EXTRA_PREFER_OFFLINE: String

Optional boolean, to be used with ACTION_RECOGNIZE_SPEECH, ACTION_VOICE_SEARCH_HANDS_FREE, ACTION_WEB_SEARCH to indicate whether to only use an offline speech recognition engine. The default is false, meaning that either network or offline recognition engines may be used.

Depending on the recognizer implementation, these values may have no effect.

Value: "android.speech.extra.PREFER_OFFLINE"

EXTRA_PROMPT

static val EXTRA_PROMPT: String

Optional text prompt to show to the user when asking them to speak.

Value: "android.speech.extra.PROMPT"

Value: "android.speech.extra.REQUEST_WORD_TIMING"

EXTRA_RESULTS

static val EXTRA_RESULTS: String

An ArrayList<String> of the recognition results when performing ACTION_RECOGNIZE_SPEECH. Generally this list should be ordered in descending order of speech recognizer confidence. (See EXTRA_CONFIDENCE_SCORES). Returned in the results; not to be specified in the recognition request. Only present when Activity#RESULT_OK is returned in an activity result. In a PendingIntent, the lack of this extra indicates failure.

Value: "android.speech.extra.RESULTS"

EXTRA_RESULTS_PENDINGINTENT

static val EXTRA_RESULTS_PENDINGINTENT: String

When the intent is ACTION_RECOGNIZE_SPEECH, the speech input activity will return results to you via the activity results mechanism. Alternatively, if you use this extra to supply a PendingIntent, the results will be added to its bundle and the PendingIntent will be sent to its target.

Value: "android.speech.extra.RESULTS_PENDINGINTENT"

EXTRA_RESULTS_PENDINGINTENT_BUNDLE

static val EXTRA_RESULTS_PENDINGINTENT_BUNDLE: String

If you use EXTRA_RESULTS_PENDINGINTENT to supply a forwarding intent, you can also use this extra to supply additional extras for the final intent. The search results will be added to this bundle, and the combined bundle will be sent to the target.

Value: "android.speech.extra.RESULTS_PENDINGINTENT_BUNDLE"

EXTRA_SECURE

static val EXTRA_SECURE: String

Optional boolean to indicate that a "hands free" voice search was performed while the device was in a secure mode. An example of secure mode is when the device's screen lock is active, and it requires some form of authentication to be unlocked. When the device is securely locked, the voice search activity should either restrict the set of voice actions that are permitted, or require some form of secure authentication before proceeding.

Value: "android.speech.extras.EXTRA_SECURE"

EXTRA_SEGMENTED_SESSION

static val EXTRA_SEGMENTED_SESSION: String

Optional string to enable segmented session mode of the specified type, which can be EXTRA_AUDIO_SOURCE, EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS or EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS. When segmented session mode is supported by the recognizer implementation and this extra is set, it will return the recognition results in segments via RecognitionListener#onSegmentResults(Bundle) and terminate the session with RecognitionListener#onEndOfSegmentedSession().

When setting this extra, make sure the extra used as the string value here is also set in the same intent with proper value.

Depending on the recognizer implementation, this value may have no effect.

Value: "android.speech.extra.SEGMENTED_SESSION"

EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS

static val EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS: String

The amount of time that it should take after the recognizer stops hearing speech to consider the input complete hence end the recognition session.

Note that it is extremely rare you'd want to specify this value in an intent. Generally, it should be specified only when it is also used as the value for EXTRA_SEGMENTED_SESSION to enable segmented session mode. Note also that certain values may cause undesired or unexpected results - use judiciously!

Depending on the recognizer implementation, these values may have no effect.

Value: "android.speech.extras.SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS"

EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS

static val EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS: String

Optional integer to indicate the minimum length of the recognition session. The recognizer will not stop recognizing speech before this amount of time.

Note that it is extremely rare you'd want to specify this value in an intent. Generally, it should be specified only when it is also used as the value for EXTRA_SEGMENTED_SESSION to enable segmented session mode. Note also that certain values may cause undesired or unexpected results - use judiciously!

Depending on the recognizer implementation, these values may have no effect.

Value: "android.speech.extras.SPEECH_INPUT_MINIMUM_LENGTH_MILLIS"

EXTRA_SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS

static val EXTRA_SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS: String

The amount of time that it should take after we stop hearing speech to consider the input possibly complete. This is used to prevent the endpointer cutting off during very short mid-speech pauses. Note that it is extremely rare you'd want to specify this value in an intent. If you don't have a very good reason to change these, you should leave them as they are. Note also that certain values may cause undesired or unexpected results - use judiciously! Additionally, depending on the recognizer implementation, these values may have no effect.

Value: "android.speech.extras.SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS"

EXTRA_SUPPORTED_LANGUAGES

static val EXTRA_SUPPORTED_LANGUAGES: String

The key to the extra in the Bundle returned by ACTION_GET_LANGUAGE_DETAILS which is an ArrayList of Strings that represents the languages supported by this implementation of voice recognition - a list of strings like "en-US", "cmn-Hans-CN", etc.

Value: "android.speech.extra.SUPPORTED_LANGUAGES"

EXTRA_WEB_SEARCH_ONLY

static val EXTRA_WEB_SEARCH_ONLY: String

Optional boolean, to be used with ACTION_WEB_SEARCH, to indicate whether to only fire web searches in response to a user's speech. The default is false, meaning that other types of actions can be taken based on the user's speech.

Value: "android.speech.extra.WEB_SEARCH_ONLY"

FORMATTING_OPTIMIZE_LATENCY

static val FORMATTING_OPTIMIZE_LATENCY: String

Optimizes formatting latency. This will result in a slightly lower quality of punctuation but can improve the experience for real-time use cases. This is a value to use for EXTRA_ENABLE_FORMATTING.

Value: "latency"

FORMATTING_OPTIMIZE_QUALITY

static val FORMATTING_OPTIMIZE_QUALITY: String

Optimizes formatting quality. This will increase latency but provide the highest punctuation quality. This is a value to use for EXTRA_ENABLE_FORMATTING.

Value: "quality"

Value: "web_search"

LANGUAGE_SWITCH_BALANCED

static val LANGUAGE_SWITCH_BALANCED: String

A value to use for EXTRA_ENABLE_LANGUAGE_SWITCH.

Enables language switch only when a new language is detected as at least SpeechRecognizer#LANGUAGE_DETECTION_CONFIDENCE_LEVEL_CONFIDENT, which means the service is balancing between detecting a new language confidently and switching early.

getVoiceDetailsIntent

static fun getVoiceDetailsIntent(context: Context!): Intent!

Returns the broadcast intent to fire with Context#sendOrderedBroadcast(Intent, String, BroadcastReceiver, android.os.Handler, int, String, Bundle) to receive details from the package that implements voice search.

This is based on the value specified by the voice search Activity in DETAILS_META_DATA, and if this is not specified, will return null. Also if there is no chosen default to resolve for ACTION_WEB_SEARCH, this will return null.

If an intent is returned and is fired, a Bundle of extras will be returned to the provided result receiver, and should ideally contain values for EXTRA_LANGUAGE_PREFERENCE and EXTRA_SUPPORTED_LANGUAGES.

(Whether these are actually provided is up to the particular implementation. It is recommended that Activitys implementing ACTION_WEB_SEARCH provide this information, but it is not required.)
