Introduction to SALT Web Tutorial
The Introduction to Speech Applications Language Tags tutorial demonstrates how to build spoken language dialogue applications on a Windows PC using the free Microsoft Speech add-in for Internet Explorer. The tutorial takes you through the SALT architecture and software installation then gives working demonstrations of the SALT language using speech synthesis and speech recognition.

The KLAIR project aims to build and develop a computational platform to assist research into the acquisition of spoken language. KLAIR is a sensori-motor server that displays a virtual infant on screen that can see, hear and speak.
CochSim is a dynamic simulation of the time and frequency analysis performed by the ear. Sound signals such as sinewaves, pulse trains, sawtooth waves and vowels can be fed into an auditory filterbank and the output monitored in a moving animated display. The program shows the vibration of the oval window and the basilar membrane, the haircell activity against filter frequency and time, and an average excitation pattern across the cochlea.
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.
ESynth is a free program designed to explain the harmonic analysis and synthesis of signals. With ESynth you can create signals by adding together individual sinusoidal waveforms (sinewaves) and study the resulting waveform and spectrum. You can also perform an analysis of an input waveform, to see how a given sound can be represented in terms of a sum of sinewaves.
RTGRAM is a free program for displaying a real-time scrolling speech spectrogram on Windows computers.
