I am using the sample application Audio playback and recording available along with the STM32F4 evaluation kit. The sample application will save the recorded file to USB memory stick. Currently we are using this recorded file for speech processing. We are observing that  the recorded file have noise and lot of glitches between the words. Also we can observe missing words in the speech.

For eg: if we are speaking the sentence " We are testing 1 2 3 4 5" the recorded file play like "we are te1 2 3 4 5".

    Can you give some suggestion on how to improve this sound quality by removing missing words and glitches.
