Usage

Linking the Library

In order to use Speech, you must first link the library your project. There's excellent documentation on how to do this in the React Native Docs.

Speaking an Utterance

Once you've linked the library, you'll want to make it available to your app by requiring it:

var Speech = require('react-native-speech');

Speaking an utterance is as simple as calling:

Speech.speak({
  text: 'React Native Speech is awesome!  I\'m going to use it in my next project.',
  voice: 'en-US'
});

Example

Using Speech in your app will usually look like this:

var Speech = require('react-native-speech');

var YourComponent = React.createClass({
  _startHandler() {
    Speech.speak({
      text: 'Aujourd\'hui, Maman est morte. Ou peut-être hier, je ne sais pas.',
      voice: 'fr-FR'
    })
    .then(started => {
      console.log('Speech started');
    })
    .catch(error => {
      console.log('You\'ve already started a speech instance.');
    });
  },

  _pauseHandler() {
    Speech.pause();
  },

  _resumeHandler() {
    Speech.resume();
  },

  _stopHandler() {
    Speech.stop();
  },

  render() {
    return (
      <View>
        ...
        <Button onPress={this._startHandler}>
          Speak
        </Button>
        <Button onPress={this._pauseHandler}>
          Pause
        </Button>
        <Button onPress={this._resumeHandler}>
          Resume
        </Button>
        <Button onPress={this._stopHandler}>
          Stop
        </Button>
      </View>
    );
  }
});
