Resources and Tools in Speech, Hearing and Phonetics

Lecture Course Notes

Course handbooks for some lecture courses run in the Department of Speech, Hearing and Phonetic Sciences can be found on-line. More information.

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. More information.

Phonetics and Phonetic Symbols

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

Historical Phonetics

Restored films of Phonetic research from the UCL Phonetics film archive. More information.


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. More information.

Speech Audio

The department has been involved building a number of language resources. These include the LUCID corpora, the UCL speaker variability database, the SCRIBE corpus of spoken British English, and the EUROM corpus of eight European languages. Also advice on equipment for making speech recordings, putting sound on web pages, or working with sound on your computer. More information.

Conference & Workshop Proceedings

The department regularly runs conferences and workshops. Some of the outputs of those meetings can be viewed on these pages. More information.

Publications and Supplementary Materials

Some working papers and supplementary materials can be found on-line. More information.

Specialist facilities

The department has specialist facilities for research in the production and perception of speech, including a set of auditory booths in our listening centre and an anechoic recording chamber. The Infant & Child Language Research Centre has specialist facilities for working with babies and young children.

Web Shop

Some educational materials are available to purchase on CD from our Web Shop.

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. More information.

WASP - Record & display speech signals

WASP is a simple program to record speech signals and to display a spectrogram and pitch track. More information.
