    HTK Files are audio files used and created in the Hidden Markov Model Toolkit for speech recognition analysis. The Hidden Markov Model Toolkit (HMM) was developed by Cambridge University to function as a speech recognition toolkit. It uses HTK files, which are audio files. These files contain audio that is used in speech recognition analysis. The HMM creates these files by converting standard audio files like WAV files into HTK format. If you do not want to use the HMM to listen to the audio in an HTK file, you will need to convert your file to a standard audio format. The converted file can then be played on a media player.


    You must add a file first, either by dragging it into the conversion area or by clicking within this area and selecting a file. Run the file conversion procedure after this. The result to HTK conversion process will be available for download.
