RSRE (Royal Signals and Radar Establishment) Speech Data Base Recordings (1983). Part 1. Specification of Vocabulary and Recording Procedure

摘要

This is the first of a series of reports which describe a database of speech recordings currently being made at RSRE by the Automatic Speech Recognition Section (T46) and Acoustics Section (T47). The vocabulary which forms the basis of the database can be conveniently divided into two parts. The first part is an anglicised version of the Diagnostic Rhyme Test (DRT) Form IV. This will be used in T47 for the assessment of speech communications equipment by subjective intelligibility tests, and in T46 for the evaluation of automatic speech recognition systems. In addition, T46 will exploit the minimally contrastive pairs of rhyming words in the DRT in research which is directed towards the development of advanced speech recognition algorithms. The second part of the vocabulary consists of the ten digits, the twenty-six letters of the alphabet and the sixty most frequent words in telephone conversational speech. (Author)
