React Native Speech To Text

A Speech To Text library for React Native. Documentation here.

Contribute to make this a universal module!

Help Wanted

If you want to contribute with some small problems, here I leave you a list with some of them:

• Returns the result to the second time of pressing the start button
• An error occurs with "User authorized access to speech recognition": logDictationFailedWithError

It would be convenient to place a button with the events: PressIn (startSpeech) and PressOut (stopSpeech) of TouchableHighlight with a sound that indicates when it begins to recognize (AudioServicesPlaySystemSound)

Example

Full example for iOS platform located in /iosSpeechToText.

Usage

var Voice = NativeModules.SpeechManager;

export default class iosSpeechToText extends Component {

  constructor(props){
    super(props);
    this.state = {
      word: ""
    }
  }
  
  startSpeech(){
    Voice.microphoneTapped();
  }

  stopSpeech(){
    var self = this;
    Voice.stopRecording(function(o) {

      if(o.result){
        self.setState({
          word: o.result
        })
      }else{
        alert("No result")
      }
    });
  }
  
  render() {
    return (
      <View style={styles.container}>
        <Text style={styles.welcome}>
          Start -> Speak -> Stop
        </Text>
        <Text style={styles.instructions}>
          {this.state.word}
        </Text>

          <Button title="start" style={{marginBottom:30}} onPress={this.startSpeech.bind(this)}></Button>
          <Button title="stop" onPress={this.stopSpeech.bind(this)}></Button>
      </View>
    );
  }
}
