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.
