“TalkBox” is a pretty common name.  It is used in a variety of domains, such music or voice-based web apps.  We use the name as a riff on the BeetBox Project by Scott Garner, which is a simple musical instrument that allows users to play drum beats by touching actual beets.  Both TalkBox and BeetBox use Raspberry Pi and touch capacitors.
