| .SH DESCRIPTION |
| .PP |
| This program converts audio files (in either Microsoft WAV, NIST |
| Sphere, or raw format) to acoustic feature files for input to |
| batch-mode speech recognition. The resulting files are also useful |
| for various other things. A list of options follows: |
| .\ |
| .PP |
| Currently the only kind of features supported are MFCCs (mel-frequency |
| cepstral coefficients). There are numerous options which control the |
| properties of the output features. It is \fBVERY\fR important that |
| you document the specific set of flags used to create any given set of |
| feature files, since this information is \fBNOT\fR recorded in the |
| files themselves, and any mismatch between the parameters used to |
| extract features for recognition and those used to extract features |
| for training will cause recognition to fail. |
