The LUCEA database is a database of existing speech recordings of L1 and L2 speakers of English. The recorded speakers are students from an international student community where English is used as lingua franca. These students are being recorded longitudinally throughout their 3-year period on campus, using read and spontaneous speech in L1 and in L2 English (or in L1 English only). The database is of interest for research and development in linguistics, language education (pronunciation training), speech technology (foreign accent detection, language recognition, speech recognition), and sociophonetics. The corpus now contains data from about 850 interviews from 282 unique students. Each interview contains about 20 minutes of speech. The speech corpus is augmented with participants’ responses from entry and exit questionnaires, and supplementary data about the participants and about each recording. When finished in 2016, the total corpus will contain about 3 TB (about 3000 GB) of audio data.
