Abstract
A system and method for utilizing a plain-old-telephone (“POT”) to interface with a digital assistant system. The POT is linked to an interface adapted to selectively provide a bidirectional audio connection to a standard telephone communication network, or to provide an interface to a digital assistant system in response to user voice commands. The functionality of the POT digital assistant interface being dependent upon the user input—DTMF tone/pulse dialing signals as opposed to voice commands spoken into the POT mouthpiece. Audio cues and prompts, as well as audio responses from the digital assistant system are provided to the user via the POT earpiece. Digital assistant functionality is provided via a simple and familiar interface, without impeding any standard voice telephony functionality (making/receiving calls, call waiting, caller ID, etc.)
