[Feature Request]: Add the ability to modulate the image when talking

[quellus]

Is your feature request related to a problem? Please describe.

Some users may prefer different ways to indicate talking other than the current bounce animation. For example, the Discord Reactive app will make the image darker when not talking and brighter when talking.

Describe the solution you'd like

This can be achieved by modulating the image. I also would like the transition to be smoothed.

Describe alternatives you've considered

The user totally could just change the brightness of the images to achieve the same effect, the downside is the transition wouldn't be smooth. Could be a little jarring.
