text-to-speech
implement text-to-speech feature by below code.
- Function Component
...
import Tts from 'react-native-tts';
...
const Home = () => {
...
Tts.setDefaultLanguage('en-IE');
Tts.addEventListener('tts-start', event => console.log('start', event));
Tts.addEventListener('tts-finish', event => console.log('finish', event));
Tts.addEventListener('tts-cancel', event => console.log('cancel', event));
...
const _onPressSpeech = () => {
Tts.stop();
Tts.speak('Hello, world!');
}
...
}
- Class Component
...
import Tts from 'react-native-tts';
...
export default class Home extends React.Component<Props, State> {
constructor(props: Props) {
super(props);
Tts.setDefaultLanguage('en-IE');
Tts.addEventListener('tts-start', event => console.log('start', event));
Tts.addEventListener('tts-finish', event => console.log('finish', event));
Tts.addEventListener('tts-cancel', event => console.log('cancel', event));
}
...
private _onPressSpeech = () => {
Tts.stop();
Tts.speak('Hello, world!');
}
}
- setDefaultLanguage: this is default language code. if you want to knwo language codes, see Language codes
- speak: tts will speak this sentence.
configure default voice
you can change default voice on react-native-tt. change default voice with below code.
Tts.setDefaultVoice('com.apple.ttsbundle.Yuna-compact');
you can see all supported voices with below code.
Tts.voices().then(voices => console.log(voices));
we checked all supported voices with above code.
iOS supported voices
if you set country code by setDefaultLanguage function, react-native-tts automatically set that country voice. if you already use setDefaultLanguage function for setting the coutnry, it’s better to skip this section.
you can change default voice by passing id of below list to setDefaultVoice parameter
