I'm having some real issues with it picking up my commands.

It seems like the most recent version is worse than before but I have to wait at least 1s after the 'beep' before talking else crew chief cannot undertand me.

It seems to me like there's some delay in the recording starting -- i'm not sure why this is necessary? Could you not begin listening from the start of the audio beep? Then after the beep, enough time should have passed that it can pick up the command flawlessly?

Cheers,
Luke
