The third ARPA Continuous Speech Recognition (CSR) Language Model Training Data is a set for speaker-independent, large-vocabulary speech recognition systems. This corpus is an important companion to the 1994 Benchmark Speech data collection (LDC95S23).

The text collection comprises both source text data (prepared by LDC and BBN) and derived statistical tables (compiled by CMU) of unigram, bigram and trigram word frequencies. The sources include all available WSJ texts, spanning 1987 through March 1994 and all AP and San Jose Mercury news data from the three TIPSTER volumes. (Some of the WSJ data, from 1992 through 1994, appears here for research use for the first time). This corpus is also available from the LDC as a 1995 release.

Because of restrictions imposed by the copyright holders of much of the NAB text, both the speech and text collections are available to LDC members only. For more information on how to join, send email to ldc@ldc.upenn.edu.
