const speak = async () => {
await TextToSpeech.speak({
text: 'This is a sample text.',
lang: 'en-US',
rate: 1.0,
pitch: 1.0,
volume: 1.0,
category: 'ambient',
queueStrategy: 1
});
};
const stop = async () => {
await TextToSpeech.stop();
};
const getSupportedLanguages = async () => {
const languages = await TextToSpeech.getSupportedLanguages();
};
const getSupportedVoices = async () => {
const voices = await TextToSpeech.getSupportedVoices();
};
const isLanguageSupported = async (lang: string) => {
const isSupported = await TextToSpeech.isLanguageSupported({ lang });
};
```

### getSupportedLanguages()
```typescript
getSupportedLanguages() => Promise<{ languages: string[]; }>
```
Returns a list of supported BCP 47 language tags.
**Returns:** Promise<{ languages: string[]; }>
--------------------
### getSupportedVoices()
```typescript
getSupportedVoices() => Promise<{ voices: SpeechSynthesisVoice[]; }>
```
Returns a list of supported voices.
**Returns:** Promise<{ voices: SpeechSynthesisVoice[]; }>
--------------------
### isLanguageSupported(...)
```typescript
isLanguageSupported(options: { lang: string; }) => Promise<{ supported: boolean; }>
```
Checks if a specific BCP 47 language tag is supported.
| Param | Type |
| ------------- | ------------------------------ |
| **`options`** | { lang: string; } |
**Returns:** Promise<{ supported: boolean; }>
--------------------

### Interfaces
#### TTSOptions
| Prop | Type | Description | Default |
| -------------- | ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ---------------------- |
| **`text`** | string | The text that will be synthesised when the utterance is spoken. | |
| **`lang`** | string | The language of the utterance. Possible languages can be queried using `getSupportedLanguages`. | "en-US" |
| **`rate`** | number | The speed at which the utterance will be spoken at. | 1.0 |
| **`pitch`** | number | The pitch at which the utterance will be spoken at. | 1.0 |
| **`volume`** | number | The volume that the utterance will be spoken at. | 1.0 |
| **`voice`** | number | The index of the selected voice that will be used to speak the utterance. Possible voices can be queried using `getSupportedVoices`. | |
| **`category`** | string | Select the iOS Audio session category. Possible values: `ambient` and `playback`. Use `playback` to play audio even when the app is in the background. Only available for iOS. | "ambient" |
| **`queueStrategy`** | QueueStrategy | Select the strategy to adopt when several requests to speak overlap. | QueueStrategy.Flush | 5.1.0 |
#### SpeechSynthesisVoice
The SpeechSynthesisVoice interface represents a voice that the system supports.
| Prop | Type | Description |
| ------------------ | -------------------- | ----------------------------------------------------------------------------------------------------------- |
