sphinx_cont_seg - Man Page
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
