How it works

It uses Web Speech API. Note that browser support for this API is currently limited, with Chrome having the best experience - see supported browsers for more information.

RoomClient for listening from microphone, convert to text (+ translate to the choosen language). It also provides functions to speak the selected text.

Usage

In React.tsx:

Import { RoomClient } from `@heitech/voice-library-npm`

const App = () => {
    UseEffect(()=>{
        const voiceRecognition = new RoomClient((textRecognizing:string)=>{callbackonTextRecognizing(textRecognizing)},  (textRecognized)=>{callbackOnTextRecognized(textRecognized)});
    },[])
    return ()
}

You can get text with 2 functions callbackOnTextRecognizing, callbackOnTextRecognized:

textRecognizing: string

textRecognized

.privTranslations: 
{
    privMap{
        privKeys: 'vi',
        privValues: 'Xin chào'
    }
}

Init listening + speaking:

Import { RoomClient } from `@heitech/voice-library-npm`

const Room = () => {

  const callbackonTextRecognizing = (e: string) => {
    console.log('callbackonTextRecognizing ', e);

  }
  const callbackOnTextRecognized = (e: Object) => {
    console.log('callbackOnTextRecognized ', e);
  }

   UseEffect(() => {
    const voiceRecognition = new RoomClient(
      (textRecognizing: string) => callbackonTextRecognizing(textRecognizing),
      (textRecognized: object) => callbackOnTextRecognized(textRecognized)
    );

    // init listener + speaker and translation
    voiceRecognition.initTranslation(YOUR_KEY,'vi-VN', 'en-US');
  }, [])

  return (
    // JSX here
  )
}
