The Luxembourgish-German SpeechDat(II) FDB-500 database contains the recordings of 560 Luxembourgish-German speakers (247 Males, 313 Females) recorded over the Luxembourgish 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:

- 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)

- 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)
