SPHINX_CONT_SEG(1) General Commands Manual SPHINX_CONT_SEG(1)

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
