    Voice recognition / converting voice to data with Nokia 30

    Hi, We are developing a simulated user for a mobile telecommunication network using Nokia 30. Is it possible to analyze/recognize the voice on the receiving side of a call? If yes, HOW?

    RE: Voice recognition / converting voice to data with Nokia 30

    Hi,

    If you are looking for some kind of voice recognition like
    DTMF detection, then it is not possible to do with Nokia 30.
    Nokia 30 can for example generate DTMF tones, but it can not
    detect them.

    You can use digital audio lines of the system connector of the Nokia30.
    There are four different digital audio signals on the system connector of the terminal: PCMDCLK, PCMSCLK, PCMTX and PCMRX. PCM (Pulse Code Modulation) is a method for the transmission of digital audio data. The format of the data transmission is sign-extended 13 bit linear code.

    Please, go to the:
    http://www.forum.nokia.com/main/1,35452,1_70,00.html
    and choose "Application Development" and
    download the "Audio Application Note For Nokia GSM Connectivity Terminal" document to find out more information
    about the audio lines of the Nokia 30 terminal.
