    Voice Recognition

    Hi All

    I want to record several words once in my voice using the cellular's microphone (example: "house", "in", "garden", "the").

    after recording each word individualy into a file / data base, i want to say a sentence containing those words - for example i want to say: "garden in the house".

    I want to record the sentence and break it into words (i will know where each word ends according to the quiet between each 2 words) and than i want to adjust the word i seperated to those i recorded earlier.

    when a match will be found, the text of the word will be presented on the screen.

    does anyone knows how to address this problem ??

    thanx

    Asaf

    Generally voice/speech recognition is a non-trivial task, and although CSpeechRecognitionUtility might be existing,

    thus you will likely have to develop your own method. Recording itself is easy CMdaAudioInputStream can provide you -say- a PCM16 stream, there might be examples in the Wiki about it and/or on FN main site (check www.forum.nokia.com Documentation/Symbian C++ on the left, Multimedia).
    Then try searching for speech recognition or voice recognition (with Google for example), since the algorithms you will need are not OS-specific. Most methods start with changing to the frequency domain, then do some statistical analysis.
