Jost Gippert: Our Featured Linguist!

"Buenos dias", "buenas noches" -- this was the first words in a foreign language I heard in my life, as a three-year old boy growing up in developing post-war Western Germany, where the first gastarbeiters had arrived from Spain. Fascinated by the strange sounds, I tried to get to know some more languages, the only opportunity being TV courses of English and French -- there was no foreign language education for pre-teen school children in Germany yet in those days.

Query Subject:   Speech Corpus for Neural Network Training

Query:   I am involved in a research project whose goal is to produce a software system for the control of electronic devices using continuous variables extracted from human speech. Part of this system will be a neural network that recognizes various vowels and produces tracks of pitch and formant frequencies. Training the neural network will require a large amount of data that we're hoping to get from an existing corpus, rather than creating it ourselves.

We are looking for a corpus that contains samples of many speakers producing many vowels (preferably in a less reduced register) that also contains human-validated pitch and formant (F1, F2, and F3) tracks and, if possible, bandwidth information. A corpus that contains more than just vowels is fine, since we can discard sections of the samples that do not suit our needs.

If anyone knows of a corpus like this, either freely distributed or requiring a fee, I would like to know how to get ahold of it.

I will post a summary of the replies that I receive. Thanks in advance for your time.
