HTKファイルとは？
An HTK file is an audio file used by the Hidden Markov Model Toolkit, a speech recognition research toolkit developed by Cambridge University. It contains audio used to perform speech recognition analysis. HTK files are created by converting .WAV or other standard audio files into the HTK format, using the Hidden Markov Model Toolkit.
詳細情報
A Hidden Markov Model (HMM) is a statistical model used to predict the occurrence of unobservable events by analyzing their observable consequences. For example, speech recognition devices use HMMs to predict the words a person said (to the device, an unobservable event) given an audio recording of those words (a recorded consequence of the event).
Researchers use the Hidden Markov Model Toolkit to, among other things, fine-tune the HMMs that speech recognition devices use to interpret a person's speech. To do so, the researchers manipulate and experiment with audio files saved in the HTK file format. The HTK format was developed specifically for use with the Hidden Markov Model Toolkit, and it is the toolkit's default audio format.

HTK files are meant to be used to perform speech recognition analysis using the Hidden Markov Model Toolkit. You can download the toolkit for free online.
If you want to play the audio contained within an HTK file without using the Hidden Markov Model Toolkit, you can convert your HTK file to a standard audio format using SoX or FFmpeg. Then, you can play the converted file using a media player such as VLC media player.
