    The Finnish SpeechDat(II) FDB-4000 comprises 4000 Finnish speakers (1830 males, 2170 females) recorded over the Finnish fixed telephone network. The FDB-4000 database is partitioned into 14 CDs, 13 CDs comprise 300 speakers sessions, the 14th comprises 100 speakers. The speech databases made within the SpeechDat(II) project were validated by SPEX, the Netherlands, to assess their compliance with the SpeechDat format and content specifications.
    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.
    Each speaker uttered the following items:
    ? 1 isolated digit
    ? 1 sequence of 10 isolated digits
    ? 4 numbers: 1 sheet number (5 digits), 1 telephone number (9-10 digits), 1 credit card number (16 digits), 1 PIN code (6 digits)
    ? 1 currency money amount
    ? 1 natural number
    ? 3 dates: 1 spontaneous date (birthdate), 1 prompted date, 1 relative or general date expression
    ? 2 time phrases: 1 time of day (spontaneous), 1 time phrase
    ? 3 spelled words: 1 spontaneous own forename, 1 city name, 1 phonetically rich word
    ? 5 directory assistance names: 1 spontaneous own forename, 1 spontaneous city of growing up, 1 frequent city name, 1 frequent company name, 1 common forename surname
    ? 2 yes/no questions: 1 predominantly ?yes? question, 1 predominantly ?no? question
    ? 3 application words
    ? 1 word spotting phrase using an embedded application word
    ? 4 phonetically rich words
    ? 9 phonetically rich sentences
    The following age distribution has been obtained: 545 speakers are below 16 years old, 1773 speakers are between 16 and 30, 980 speakers are between 31 and 45, 606 speakers are between 46 and 60, and 96 speakers are over 60.
    A pronunciation lexicon with a phonemic transcription in SAMPA is also included.

  • The speech recognition experiments were performed using different SpeechDat fixed telephone databases (Hoege et al., 1997; van den Heuvel et al., 2001/1).
  • The results show benefits of the usage of the proposed LDA-RefRec procedure for evaluation or development of the automatic speech recognition systems based on SpeechDat (II) compliant databases.
  • Proposed LDARefRec Toolkit is therefore found to be a powerful tool for construction and evaluation of computationally efficient automatic speech recognition systems based on SpeechDat (II) databases.
