Real-time fundamental frequency analysis
Original language description
This software can be used for the real-time fundamental frequency analysis. It enables user to simultaneously display waveform, autocorrelation function and one-side real cepstrum of input speech signal. Beside these characteristics software displays also an estimated value of fundamental frequency F0 according to methods based on autocorrelation and real cepstrum. Before the analysis is run it is possible to change the length of speech segment and sampling frequency. Thanks to this software it is possible to monitor the waveform of particular speech vocal as well as the resulting autocorrelation function dependent on the instantaneous period. It is also possible to monitor a change of level and position of 1st rahmonic part. Especially in this case itis possible to see the differences caused by hoarseness or breathiness. Watching the real spectrum it is also possible to see an effect of deconvolution of speech gain signal and vocal tract impulse response. The software must be run in
