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.

ESYNTH - Harmonic analysis/synthesis teaching tool

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. More information.

RTGRAM - Real-time Spectrographic Display

RTGRAM is a free program for displaying a real-time scrolling speech spectrogram on Windows computers. More information.
