This site provides access to the twin web apps Visible Vowels and Visible Consonants.

Visible Vowels is a web app for the analysis of acoustic vowel measurements: f0, formants and duration. Visible Consonants is a web app for the analysis of acoustic consonant measurements. The apps are useful instruments for research in phonetics, sociolinguistics, dialectology, forensic linguistics, and speech-language pathology.

For brief information about these two apps see here and here . Click here for a tutorial about Visible Vowels. Comments are welcome and can be sent to wheeringa@fryske-akademy.nl
