Visible Sounds: Visible Vowels & Visible Consonants
Web applications for analysing and visualising acoustic measurements of vowels and consonants.
Visible Vowels is a web application for analysing acoustic vowel measurements, including fundamental frequency (f0), formant frequencies, and duration.
Visible Consonants is designed for analysing acoustic consonant measurements, although it can also be used to visualise vowel variation, particularly when less commonly used acoustic parameters are involved.
Both applications can be accessed directly through their respective URLs or via Visible Sounds. An extensive tutorial for Visible Vowels is available through both Visible Vowels and Visible Sounds. The applications are valuable tools for research in phonetics, sociolinguistics, dialectology, forensic linguistics, and speech-language pathology.
Who is involved

Wilbert Heeringa
Researcher
Wilbert Heeringa is a researcher at the Fryske Akademy, working on dialectometry, phonetics and statistics. He uses computational methods to measure dialect variation and change in vocabulary, morphology and pronunciation, and develops tools for phonetic research such as Visible Sounds.

Hans Van de Velde
Researcher
Hans Van de Velde is a researcher in sociolinguistics at the Fryske Akademy. He studies language variation and change, multilingualism and phonetics, including the pronunciation of Frisian and Dutch in Fryslân, the evaluation of variations, and the development of experimental sociolinguistics.
