MP3 is an audio coding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage and a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.
An SPH file is an audio waveform file created in the NIST SPHERE format that is often used in speech recognition research. It usually contains a recording of the person speaking. SPH files are rare, so they are not supported by popular media players. You can convert SPH to WAV with MiConv.
