I have created an application but it is only support .wav files to convert audio to text. It is not showing any answers when giving .mp3 files .. I am using sphinx for to convert audio files to text. My question is that why it is not converting to text from .MP3?

As it is specified in the CMU Sphinx documents, only the linear PCM WAV audio format is accept by its speech recognizer. Therefore, any MP3 audio file will be decoded to obtain the linear PCM format, of 16khz sampling rate, 16bit/frame, little-endian and one channel (mono). This decoding is achieved by the Tarsos Transcoder 1.2. This library uses many Apache utilities, therefore beside the TarsosTranscoder.jar, mp3plugin.jar also has to be included in the project building path.
