The corpus contains phonemically segmented and labelled speech from 8 speakers. For each speaker, a Fixed text has been recorded in several "styles", and a retold version of the fixed text. Furthermore, each speaker told an Informal story face-to-face with an interviewer which was the basis of a speaker specific variable text corpus, which was read and retold by each speaker individualy.

A more extended paper describing the corpus can be found here (pdf) and here (pdf). This has been presented as a poster at the EUROSPEECH2001 conference. There is also a short "tour" available. This site runs on CGIscriptor perl inline scripting. There is a special page containing available research papers.
You can find information on the label protocol, the naming conventions, and the phoneme labels here (in Dutch) (PDF)and here (some of it in English).
Speaking styles are:
Recordings were made on two separate channels, from a fixed microphone (_fm) and from a head mounted microphone (_hm). Next to the sound files, some analysis results are available, e.g., the spectral Center of Gravity (CoG) files. The Spectral Center of Gravity is a compact way to represent spectral changes, especially changes in speech source (noise and voicing) and changes related to articulatory movements. These are stored as Praat ASCII Sound files. Sound files are CD quality (directly recorded on Audio CD), i.e., 44.1 kHz and 16 bit.
