Avatars can interact with several ways:

​
Lip-sync

The avatars generated from AvatarLabs support real-time lip-sync based on audio provided to the SDK.

To make your avatar start talking, you need to create an AudioContext and connect it to the SDK with connectAudioContext.

function App(){
    const {
        avatarDisplay,
        connectAudioElement,
        connectAudioContext,
        connectAudioNode
    } = useAvatar({
        //...
    });

    const audioContextRef = useRef<AudioContext>(new AudioContext());

    return (
        {avatarDisplay}
        <button
            onClick={() => {
              connectAudioContext(audioContextRef.current)
            }}
        >
            Connect AudioContext
        </button>
    );
}

​
Connect Audio

After connecting AudioContext, you need to create a HTMLAudioElement or AudioNode and connect it to the SDK in order to sync the audio with lip-sync system.

After connection, when you play the audio from the HTMLAudioElement, the avatar will start lip-sync automatically.

const { avatarDisplay, context, connectAudioElement } = useAvatar({
  //...
});

const audioPlayer = useRef(new Audio())

//...

return (
    {avatarDisplay}
    <button
        onClick={() => {
          connectAudioElement(audioPlayer.current, audioContextRef.current);
        }}
    >
        Connect 
    </button>

    <button
        onClick={() => {
          audioPlayer.current.src = "audio.mp3";
          audioPlayer.current.play();
        }}
    >
        Play
    </button>
)

​
Expression

Avatars created from our creation suite support different expressions.

How many expression the avatar can make depends on which model you are using to generate the avatar.

const { avatarDisplay, availableEmotions, setEmotion } = useAvatar({
  //...
});
return (
  <button
    onClick={() => {
      setEmotion(availableEmotions[0]);
    }}
  >
    Set emotion
  </button>
);
