NAME¶
sphinx_fe - Convert audio files to acoustic feature files
SYNOPSIS¶
sphinx_fe [ options ]...
DESCRIPTION¶
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 VERY important
that you document the specific set of flags used to create any given set of
feature files, since this information is NOT 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.
