Resources and Tools in Speech, Hearing and Phonetic Sciences

Web Tutorials

The Department has been involved in a number of funded projects concerned with education in Phonetics and Speech Communication. These projects and other work have led to some teaching materials that are accessible over the web.

Phonetic Symbols Advice

Advice on the use of phonetic symbols in computing applications, including downloadable keyboard layouts, fonts and more.

Software

We offer a variety of software for analysing sounds and signals, displaying waveforms and spectra, synchronising display and audio, storing and analysing speech data, and much more.

Speech Audio

Advice on equipment for making speech recordings, putting sound on web pages, or working with sound on your computer.

The department has been involved building a number of language resources. These include the UCL speaker variability database, the SCRIBE corpus of spoken British English, and the EUROM corpus of eight European languages.

CochSim - Cochlear Simulation teaching tool

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.
