    Hello All,

    I am a novice to most of this, still a student at a community college...
    I am trying to build a talking GPS unit...
    I can't seem to find the right chip to use to store and play back the audio.
    I found a few "Text to Speech" chips, but the sample audio on line was not good...
    So my next idea was to pre-record the audio elements needed,
    then load them on a chip of some sort.
    I have a list of about seventyfive words in all.
    Like ONE. TWO, Twenty, Fifty, North and so on..
    Place the elements on some kind of chip, each speech
    element with its own addressable location and the
    Pic 18F will parse out the incoming serial string,
    pick the voice elements in the order needed and
    send the audio on its way....
    I have not rcorded the voice yet, I am not locked
    into a file type, .WAV or other format is fine.
    I would like solid telephone quality audio playback.
    Say a sample rate of 8kHz, 80Hz to 3kHz, max storage
    time is 120 seconds should work ???
    Thanks in Advance,

    Allen
