.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:

|
|
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.
