VOICE-CONTROLLED COMMUNICATION CONNECTIONS

Systems and methods for voice-controlled communication connections are provided. An example system includes a mobile device being operated consecutively in listen, wakeup, authentication, and connect modes. Each of subsequent modes consumes more power than a preceding mode. The listen mode consumes less than 5 mW. In the listen mode, the mobile device listens for an acoustic signal, determines whether the acoustic signal includes voice, and upon the determination, selectively enters the wakeup mode. In the wakeup mode, the mobile device determines whether the acoustic signal includes a spoken word and, upon the determination, enters the authentication mode. In authentication mode, the mobile device identifies a user using the spoken command and, upon the identification, enters the connect mode. In the connect mode, the mobile device receives an acoustic signal, determines whether the acoustic signal includes a spoken command and performs one or more operations associated with the spoken command.
