NIST files are sound recordings stored in the National Institute of Standards and Technology's Speech Header Resources Exchange Format (SPHERE), designed for speech recognition software like Hidden Markov Model Toolkit. NIST files consist of both metadata information as well as audio data in waveform format; VLC can playback these files while soX or FFmpeg may convert them to more common ...

These waveform files include recordings of human speaking which can then be fed as input to speech recognition systems. Unfortunately, these files are quite uncommon; most popular media players do not support them. SPH files contain both human-readable headers with name value pairs arranged in ...
