sphinx_cont_seg − Segment a waveform file into non-silence regions
sphinx_cont_seg [ options ]...
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 |
