ESECTION - Speech signal cross-sections

ESection is a free program for calculating and displaying spectral and other related analyses of sections of a speech signal. It can be used to demonstrate the different spectral properties of elements of speech. It can also calculate an LPC spectrum, autocorrelation and cepstrum analyses, and can display the signal as a waveform or as a spectrogram. It automatically finds formant and fundamental frequency values. More information.

EFxHist - Fundamental Frequency Histograms

EFxHist is a program to analyse joint speech and laryngograph recordings. EFxHist locates each pitch period in the laryngograph waveform and produces statistical analyses including distributions of fundamental frequency, closed-quotient, jitter and shimmer. More information.
