    Hi all,
    I generated new model for 5 words using sphinxTrain, and it works excellent in
    pocketsphinx windows, but when i used this model in pocketsphinx android it is
    not working (sometimes it gives poor accuracy or no recognition at all). I
    have uploaded the model files in this link http://www.4shared.com/folder/Ml_C
    ylL0/_online.html
    . it
    will be very helpful if someone helps.

    Hello

    Android records audio at 8khz so you need to modify your training feature
    extraction parameters to match this. upperf should be about 3500 and number of
    filters needs to be updated accordingly.

    As of the suggestion u gave i made the models and it works. Thank u very much
    Mr.Nickolay.. But still there is a strange thing happening in recognition (It
    doesnt recognizes the word BACKWARD from my dictionary ). I have 5 words in
    dictionary and model was generated with audio files sampled at 8khz and the
    arguments are -nfilt 31,-lowerf 200,-upperf 3500 -srate 8000 and -nfft 256.
    for your information i have generated the voice samples from Festvox voice
    synthesis online
    demo.http://festvox.org/voicedemos.html
    Is there any more changes we need to do in Training arguments ?
    whether the voice samples that i have generated from Festvox would make any
    difference in recognition accuracy?

    To train the model with good accuracy you need a diverse set of speech samples
    to train the database. You can learn more details about training in tutorial
