I would like to use these expo react native events (onPause, onResume, onDone,...) which can be found here: https://docs.expo.dev/versions/v44.0.0/sdk/speech/#speecheventcallback but I cannot find any correct way to use it. Can anyone please help me with syntax? I haven't found any examples at all. Thank you Jan
const [Playing,setPlaying] = useState(false);
const Text = 'Mom I missed you';
const play = () => {
Speech.speak(Text,{
rate:1,
onStart:() => setPlaying(true),
onPause:() => setPlaying(false),
onResume:() => setPlaying(true)
})
}
return (
<Button title = 'play' onPress = {play}/>
)
Basically on each events(start, resume, pause) respective callback functions will be called.. don't know about onBoundary and onMark. basically there is a boundary event for SpeechSysthesisUtterance(an api for text to speech for web browsers) maybe onBoundary is related to that.
//This is only for Web-Apps
let utt = new SpeechSynthesisUtterance('Hello everyone');
utt.addEventListener('boundary' ,(e) => {
console.log(e.charIndex)
});
speechSynthesis.speak(utt);
e.charIndex is index of Text. https://www.youtube.com/watch?v=nx_k1XCaWWs check at 13:30 min
