What is the difference between .htk and .nist?

Name: Hidden Markov Model Toolkit File; NIST Sphere
Extension: .htk; .nist
Format: Binary; Binary
Category: Audio; Audio
Developer: Cambridge University's Speech Group.; National Institute of Standards and Technology
Description: Single channel 16-bit PCM format used by HTK, a toolkit for building Hidden Markov Model speech processing tools.; SPHERE (SPeech HEader Resources) is a file format defined by NIST (National Institute of Standards and Technology) and is used with speech audio. SoX can read these files when they contain μ-law and PCM data. It will ignore any header information that says the data is compressed using shorten compression and will treat the data as either μ-law or PCM. This will allow SoX and the command line shorten program to be run together using pipes to encompasses the data and then pass the result to SoX for processing.
