*** ** * ** ***

Provides support for the TalkBack screen reader, which users can activate to
navigate a watch face using touch and voice input.

Every group- or part-based element supports the `ScreenReader` element.

Introduced in Wear OS 4.

## Syntax

```xml
<ScreenReader stringId="string">
    <Parameter expression="string">
    </Parameter>
</ScreenReader>
```

## Attributes

The `ScreenReader` element has one required attribute, `stringId`. This is a
string that identifies this specific instance of `ScreenReader`.

## Inner elements

The `ScreenReader` element can contain any number of `Parameter` inner element
instances. The `Parameter` inner element must contain the `expression`
attribute, which is a string that represents an [arithmetic expression](https://developer.android.com/training/wearables/wff/common/attributes/arithmetic-expression). This
expression allows for dynamically representing real-time attribute values and
gyroscopic effects.
