Note that G729 reaches a bit rate as low as 8 kbps by sending prediction coefficients only once every four frame. 3 Going further Various tools and interactive tutorials on LP modeling of speech are available on the web (see Fellbaum 2007, for instance). MATLAB code by A. Spanias for the LPC10e coder can be found on the web (Spanias and Painter 2002). com website (Khan and Kashif 2003). D. Ellis provides interesting MATLAB-based audio processing examples on his web pages (Ellis 2006), among which are a sinewave speech analysis/synthesis demo (including LPC) and a spectral warping of LPC demo.
Its information content is hidden. In order to reveal it to the eyes, let us plot a spectrogram of the signal (Fig. 11). We then choose a wideband spectrogram7 by imposing the length of each frame to be approximately 5 ms long (40 samples) and a hamming weighting window. specgram(speech,512,8000,hamming(40)) In this plot, pitch periods appear as vertical lines. As a matter of fact, since the length of analysis frames is very small, some frames fall on the 6 7 This sentence was taken from the Open Speech Repository on the web.
Its spectrum (Fig. 16), however, has the same broad features as that of the residual: flat envelope and harmonic content corresponding to F0. The main difference is that the excitation spectrum is “over-harmonic” compared to the residual spectrum. ” synt_frame=filter(gain,ai,excitation); plot(synt_frame); periodogram(synt_frame,,512); Although the resulting waveform is obviously different from the original one (this is due to the fact that the LP model does not account for the phase spectrum of the original signal), its spectral envelope is identical.
