*** ** * ** ***

List of alternative hypotheses for a specific span of a speech recognition result string.

A single[SpeechRecognizer](https://developer.android.com/reference/android/speech/SpeechRecognizer)result is represented as a[String](https://developer.android.com/reference/java/lang/String). For a specific span of the originally recognized result string, the recognizer may provide alternative hypotheses of what it may have recognized. A span is specifically a substring and is thereby defined by its start and end positions in the originally recognized string. Alternative hypotheses are represented as strings which may replace that substring.

These alternatives can be used to enhance recognition by adding/re-ranking/applying or in other ways manipulating the SpeechRecognizer results before powering dictation features.

## Public methods

### describeContents

Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)  

```
public int describeContents ()
```

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of[writeToParcel(android.os.Parcel, int)](https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)), the return value of this method must include the[CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR)bit.

| `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either`0`or[CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR) <br /> |

### equals

Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)  

```
public boolean equals (Object o)
```

Indicates whether some other object is "equal to" this one.

The`equals`method implements an equivalence relation on non-null object references:

- It is*reflexive* : for any non-null reference value`x`,`x.equals(x)`should return`true`.
- It is*symmetric* : for any non-null reference values`x`and`y`,`x.equals(y)`should return`true`if and only if`y.equals(x)`returns`true`.
- It is*transitive* : for any non-null reference values`x`,`y`, and`z`, if`x.equals(y)`returns`true`and`y.equals(z)`returns`true`, then`x.equals(z)`should return`true`.
- It is*consistent* : for any non-null reference values`x`and`y`, multiple invocations of`x.equals(y)`consistently return`true`or consistently return`false`, provided no information used in`equals`comparisons on the objects is modified.
- For any non-null reference value`x`,`x.equals(null)`should return`false`.

An equivalence relation partitions the elements it operates on into*equivalence classes*; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

```

### getEndPosition

Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)  

```

|-------|--------|
| `int` | <br /> |

### getStartPosition

Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)  

```
public int getStartPosition ()
```

The start position of the span of the originally recognized string.

Must be set to a non-negative value before building.

<br />

|    Returns    ||
|-------|--------|
| `int` | <br /> |

### hashCode

Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)  

```
public int hashCode ()
```

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by[HashMap](https://developer.android.com/reference/java/util/HashMap).

The general contract of`hashCode`is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the`hashCode`method must consistently return the same integer, provided no information used in`equals`comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the[equals](https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object))method, then calling the`hashCode`method on each of the two objects must produce the same integer result.
- It is*not* required that if two objects are unequal according to the[equals](https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object))method, then calling the`hashCode`method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
