Voice enabling mobile services leverage existing PTT infrastructure. Initiation of a service request and navigation through PTT service functions is accomplished by voice direction, rather than by reading choices and texting or clicking through options. A mobile phone includes a dedicated push-to-talk service button for generating a signal for initiating a voice enabled service session, a speaker and microphone for transducing sounds and electrical signals, a display for displaying visual information to a user, memory for storing data, a transceiver for receiving and transmitting data and a processor. The processor receives a signal generated by the PTT service button for initiating a voice enabled service session, communicates a prompt to a user to begin speaking, stores voice data from a user and transmits the stored voice data to a service server for transforming the voice data to a result satisfying the spoken voice service request.
