Wave Viewer is a Matlab-based analysis tool for speech waveforms.
viewer_end_state = wave_viewer(y, [options])
Wave Viewer takes a signal y
and the following optional arguments:
fs
sampling rate (default: 11025)ms_framespec_gram
(default: broadband)ms_framespec_form
(default: narrowband)nfft
number of FFT points/bins (default: 4096)nlpc
number of LPC coefficients (default: 15)nformants
number of formants to track (default: 3)preemph
pre-emphasis factor (default: 0.95)pitchlimits
low and high frequency cutoffs for pitch tracking (default: [50 300])ampl_thresh4voicing
voicing threshold (default: 0 (don't apply a voicing threshold))
or a single argument sigproc_params
, a parameter struct from the viewer_end_state
returned by the function.
Wave Viewer requires a few functions from Matlab's Signal Processing Toolbox (zp2ss and abcdchk).
