Pitu Danish nonsense syllable

This is the homepage for the Pitu Danish nonsense syllable project.

The Pitu speech material consists of recordings of nonsense syllables spoken by 27 native talkers of Danish made in an anechoic chamber. 17 Danish consonants were used [ptkbdgfsvmnrlhjSW] (notation described in (Henrichsen, 2007), special version of SAMPA). One of three vowels [iau] followed the initial consonant (vowel [a] = [z] in the notation of Henrichsen (2007)). A second syllable [tu] followed the CV-syllables in order to ensure that no token was "accidentally" a Danish word. Each syllable was repeated three times following the standard intonation pattern for Danish (falling F0). Please refer to the documentation for further details.

An introduction to the speech corpus can be found in this pdf file.
