Use cases:

Case 1: Normal live speech on PTT

When new access panel are added to a project they will have live speech ready on the ptt button. This is set up without zones and priority 21.

Adding a zone select button on a different dak key will allow this function to be used.

Setting the live speech function to "wait for ptt" will allow a handheld microphone to be used. Triggering the function will prime the access panel, and the next press on the handheld microphone will start the audio.
