.TH SPHINX_CONT_SEG 1 "2008-05-12" .SH NAME sphinx_cont_seg \- Segment a waveform file into non-silence regions .SH SYNOPSIS .B sphinx_cont_seg [\fI options \fR]... .SH DESCRIPTION .PP 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: .TP .B \-adcdev of audio device to use for input. .TP .B \-alpha Preemphasis parameter .TP .B \-argfile file giving extra arguments. .TP .B \-dither Add 1/2-bit noise .TP .B \-doublebw Use double bandwidth filters (same center freq) .TP .B \-frate Frame rate .TP .B \-infile of audio file to use for input. .TP .B \-input_endian Endianness of input data, big or little, ignored if NIST or MS Wav .TP .B \-lifter Length of sin-curve for liftering, or 0 for no liftering. .TP .B \-logspec Write out logspectral files instead of cepstra .TP .B \-lowerf Lower edge of filters .TP .B \-ncep Number of cep coefficients .TP .B \-nfft Size of FFT .TP .B \-nfilt Number of filter banks .TP .B \-remove_dc Remove DC offset from each frame .TP .B \-remove_noise Remove noise with spectral subtraction in mel-energies .TP .B \-remove_silence Enables VAD, removes silence frames from processing .TP .B \-round_filters Round mel filter frequencies to DFT points .TP .B \-samprate Sampling rate .TP .B \-seed Seed for random number generator; if less than zero, pick our own .TP .B \-singlefile a single cleaned file. .TP .B \-smoothspec Write out cepstral-smoothed logspectral files .TP .B \-transform Which type of transform to use to calculate cepstra (legacy, dct, or htk) .TP .B \-unit_area Normalize mel filters to unit area .TP .B \-upperf Upper edge of filters .TP .B \-vad_postspeech Num of silence frames to keep after from speech to silence. .TP .B \-vad_prespeech Num of speech frames to keep before silence to speech. .TP .B \-vad_startspeech Num of speech frames to trigger vad from silence to speech. .TP .B \-vad_threshold Threshold for decision between noise and silence frames. Log-ratio between signal level and noise level. .TP .B \-verbose Show input filenames .TP .B \-warp_params defining the warping function .TP .B \-warp_type Warping function type (or shape) .TP .B \-wlen Hamming window length .SH AUTHOR Written by M.
