WSJCAM0 Cambridge Read News

This release of WSJCA0 represents version 1.1 of the corpus, which was initially released on tape by Cambridge University as of August 31, 1994. This collection was modelled directly on the ARPA CSR Corpus released by LDC in 1993: it used the same dual-microphone recording paradigm and a subset of prompting texts drawn from the Wall Street Journal.

There are two key differences between WSJ0 and WSJCAM0: (1) the subjects in WSJCAM0 were native speakers of British English and (2) in addition to standard orthographic transcripts, WSJCAM0 also has information on the time alignment between the sampled waveform and both the words and the phonetic segments. The contents of the publication consist of the following: Training data from head-mounted microphone Development test data from head-mounted microphone, plus first set of evaluation test data Training data from desk-mounted microphone Development test data from desk-mounted microphone, plus second set of evaluation test data There are 90 utterances from each of 92 speakers that are designated as training material for speech recognition algorithms.
