Flemish SpeechDat(II) FDB-1000

The Flemish SpeechDat(II) FDB-1000 database contains the recordings of 1,023 Flemish speakers (461 Males, 562 Females) recorded over the Belgian fixed telephone network.

Speech samples are stored as sequences of 8-bit 8 kHz A-law. Each prompted utterance is stored in a separate file. Each signal file is accompanied by an ASCII SAM label file, which contains the relevant descriptive information.

This speech database was validated by SPEX (the Netherlands) to assess its compliance with the SpeechDat format and content specifications.

Each speaker uttered the following items. Each phrase or word was repeated about 5 times.

- 7 application words
- 4 isolated digits
- 1 sequence of 10 isolated digits
- 5 connected digits (1 area code, 1 spontaneous phone number, 1 credit card number –15/16 digits, etc.)
- 3 dates (1 spontaneous date e.g. birthday, 1 prompted date, 1 general and relative date expression)
- 1 embedded application word
- 4 spelled words
- 1 currency money amount
- 1 natural number
- 6 directory assistance names (1 forename, 1 city of birth, 1 most frequent city, 1 city name, 1 company name, 1 "forename surname")
- 2 yes/no questions (1 predominantly "yes" question, 1 predominantly "no" question)
- 10 phonetically rich sentences
- 2 time phrases (1 spontaneous time of day, 1 time phrase)
- 5 phonetically rich words
The following age distribution has been obtained: 22 speakers are under 16, 387 speakers are between 16 and 30, 306 speakers are between 31 and 45, 240 speakers are between 46 and 60, 68 are over 60.
