Text to Speech: Random voice from a list

Currently only a single voice is supported:

{{tts en_US voices=Apple_Fred:Field}}

What I want is randomly choosing a voice from a list, therefore I can hear different voices in different cards:

{{tts en_US voices=random:[Apple_Fred,Apple_Alex,Apple_Samantha]:Field}}

if you are looking for a large voice library, yo should try using the Wavel AI text to speech online
it has over 250 voices available along with a voice cloning feature
