LILA Korean database
The LILA Korean database collected in South Korea was recorded within the scope of the LILA project. It contains the recordings of 1,000 Korean speakers (500 males and 500 females) recorded over the Korean mobile telephone network. The following acoustic conditions were selected as representative of a mobile user's environment (some speakers were recorded in several environments): - Passenger in moving car, railway, bus, etc. (152 speakers) - Public place (148 speakers) - Stationary pedestrian by road side (150 speakers) - Home/office environment (350 speakers) - Passenger in moving car using a hands-free kit (200 speakers) This database is distributed as 1 DVD-ROM. The speech files are stored as sequences of 8-bit, 8kHz A-law speech files and are not compressed, according to the specifications of LILA. Each prompt utterance is stored within a separate file and has an accompanying ASCII SAM label file. This speech database was validated by SPEX (the Netherlands) to assess its compliance with the LILA format and content specifications. Each speaker uttered the following items: - 4 isolated digits - 1 sequence of 9 isolated digits - 1 sequence of 11 isolated digits - 6 connected digits (1 sheet number -5+ digits, 2 read telephone numbers –9/11 digits, 1 credit card number –14/16 digits, 1 PIN code -6 digits, 1 spontaneous telephone number) - 1 natural number - 1 currency money amount - 2 yes/no questions (1 predominantly “yes” question, 1 predominantly “no” question) - 3 dates (1 spontaneous date e.g. birthday, 1 word style prompted date, 1 relative and general date expression) - 2 time phrases (1 spontaneous time of day, 1 word style time phrase) - 6 application words (out of a set of 30) - 1 spotting phrase using an embedded application word - 5 directory assistance names (1 spontaneous, e.g. own surname, 1 city of birth/growing up, 1 most frequent city out of a set of 500, 1 most frequent company/agency out of a set of 500, 1 “forename surname” out of a set of 150 ) - 3 spelled words (1 surname, 1 directory assistance city name, 1 real/artificial name for coverage) - 1 “silence word” - 4 phonetically rich words - 13 phonetically rich sentences - 6 spontaneous items for control The following age distribution has been obtained: 361 speakers are between 16 and 30, 360 speakers are between 31 and 45, and 279 speakers are between 46 and 60. A pronunciation lexicon with a phonemic transcription in SAMPA is also included.
