Resources and Tools in Speech, Hearing and Phonetic Sciences
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.
Advice on the use of phonetic symbols in computing applications, including downloadable keyboard layouts, fonts and more.
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.
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.
Conference & Workshop Proceedings
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.
Some educational materials are available to purchase on CD from our Web Shop.

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.
BROWSE is a program for browsing audio recordings. With BROWSE you can drag and drop audio files in a range of formats onto the display to see and hear their contents. BROWSE allows you to zoom, scroll and save the audio files to other formats.
