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.


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.

ESECTION - Speech signal cross-sections

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 - Simple tool for browsing audio files

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.
