Twilio Voice volume control

Question

I'm running the Browser Calls for Python - Flask example, and was wondering if there is a way to control the speaker volume on the Twilio Client side?

On other voice solutions, I used to manipulate the volume via the HTML5 element, but it seems that Twilio doesn't use one.

Twilio developer evangelist here.

I checked with the Twilio Client JS team and the audio is played using the Web Audio API. As such, there is no way, built in or otherwise, to control the volume.

You can get information about the volume from the library though, check the Device.audio methods and events.
