Automated or intelligent mute/un-mute
Many times when you want to speak or respond quickly in a meeting, it´s not always easy to find he mute button quickly enough. The idea here is to create a way either configurable or not to have an alternative means to unmute and mute quickly. For example, it could be a keyboard shortcut, or a specific keyword that when said the app will recognise and activate the mute button.
Discord: Hold spacebar is a nice implementation. It will have you on mute unless you are holding the spacebar. This wouldn't be ideal for all meetings but it would be nice. Say if you hold the space for more than 30 seconds it will then alert you that you can release the spacebar.
This shouldn't be a default but an option.
