SFS How-To Guides

1. How to use SFS to transcribe speech signals

This how-to guide provides a tutorial introduction to the use of SFS for the orthographic and phonetic transcription of a speech recording, including tools for automatic alignment of phonetic transcription to the signal. This tutorial refers to versions 4.6 and later of SFS.

2. How to use SFS for formant analysis

This how-to guide provides a tutorial introduction to the use of SFS for the analysis of the phonetic properties of speech based on measurements of formant frequencies. The tutorial demonstrates how to annotate the signal, how to perform formant analysis, how to extract formant frequencies and how to analyse the resulting data sets. This tutorial refers to versions 4.6 and later of SFS.

3. How to use SFS with the HTK Hidden Markov modelling toolkit

This how-to guide provides a tutorial introduction to the use of SFS in combination with the Cambridge Hidden Markov modelling toolkit (HTK) for pattern processing of speech signals. The tutorial covers installation, file conversion, phone and phone-class recognition, phonetic alignment and pronunciation variation analysis. This tutorial refers to versions 4.6 and later of SFS with version 3.3 of HTK.

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.
