Mute, volume and blocked audio
Mute the microphone, set the agent's volume, recover blocked audio, draw a mic meter.
await wayloVoice.setMuted(true);
wayloVoice.setVolume(0.5); // 0 to 1
await wayloVoice.resumeAudio(); // from a click, when state.playback is 'blocked'
wayloVoice.getMicrophoneLevel(); // 0 to 1, for a mic meter; poll it with requestAnimationFramesetMuted()works beforestart()too.- While muted, the browser's mic indicator stays on and
getMicrophoneLevel()is 0. - iOS Safari ignores volume levels, but 0 still mutes.
Blocked audio
A browser can block the agent's voice, most often when start() ran after an await in the click handler. Then state.playback is blocked. Show a button, and call resumeAudio() from its click:
wayloVoice.on('state', state => {
resumeButton.hidden = state.playback !== 'blocked';
});
resumeButton.addEventListener('click', () => void wayloVoice.resumeAudio());
