NAME
sphinx_cont_seg - Segment a waveform file into non-silence regions
SYNOPSIS
sphinx_cont_seg [ options ]...
DESCRIPTION
This program reads an input file and segments it into individual non-silence regions. It can process either file or read data from microphone. Use following arguments:
- -adcdev
-
of audio device to use for input.
- -alpha
-
Preemphasis parameter
- -argfile
-
file giving extra arguments.
- -dither
-
Add 1/2-bit noise
- -doublebw
-
Use double bandwidth filters (same center freq)
- -frate
-
Frame rate
- -infile
-
of audio file to use for input.
- -input_endian
-
Endianness of input data, big or little, ignored if NIST or MS Wav
- -lifter
-
Length of sin-curve for liftering, or 0 for no liftering.
- -logspec
-
Write out logspectral files instead of cepstra
- -lowerf
-
Lower edge of filters
- -ncep
-
Number of cep coefficients
- -nfft
-
Size of FFT
- -nfilt
-
Number of filter banks
- -remove_dc
-
Remove DC offset from each frame
- -remove_noise
-
Remove noise with spectral subtraction in mel-energies
- -remove_silence
-
Enables VAD, removes silence frames from processing
- -round_filters
-
Round mel filter frequencies to DFT points
- -samprate
-
Sampling rate
- -seed
-
Seed for random number generator; if less than zero, pick our own
- -singlefile
-
a single cleaned file.
- -smoothspec
-
Write out cepstral-smoothed logspectral files
- -transform
-
Which type of transform to use to calculate cepstra (legacy, dct, or htk)
- -unit_area
-
Normalize mel filters to unit area
- -upperf
-
Upper edge of filters
- -vad_postspeech
-
Num of silence frames to keep after from speech to silence.
- -vad_prespeech
-
Num of speech frames to keep before silence to speech.
- -vad_startspeech
-
Num of speech frames to trigger vad from silence to speech.
- -vad_threshold
-
Threshold for decision between noise and silence frames. Log-ratio between signal level and noise level.
- -verbose
-
Show input filenames
- -warp_params
-
defining the warping function
- -warp_type
-
Warping function type (or shape)
- -wlen
-
Hamming window length
