S0010 : Dutch Polyphone database

The Dutch Polyphone corpus contains the recordings of 5,050 Dutch speakers recorded over the fixed telephone network (ISDN line). The corpus comprises 222,075 speech files (based on 44 or, in a few cases 43 items per speaker), which all have been orthographically transcribed. The data were collected in 8-bit A-law digital form.

The corpus contains both read and extemporaneous items.

The recorded items consist of isolated digits, numbers (one telephone number, two bank accounts or credit card numbers, and the participation number), a postal code, guilder amounts, time, date, amounts, application words, sentences with application word, phonetically rich sentences, spelled words, city names.

Several questions were asked to get some spontaneous speech (e.g. Is Dutch your native language?, Did you ever live in another country than the Netherlands? In which cities did you grow up? Are you a man or a woman? Are you calling from your home phone?, etc.).
