Summary:Describes the collection of a phonetically-rich isolated-word
telephone-speech database, “PhoneBook”, which was undertaken
because of (1) the lack of available large-vocabulary isolated-word
data, (2) anticipated continued importance of isolated-word and
keyword-spotting technology to speech-recognition-based applications
over the telephone, and (3) findings that continuous-speech training
data is inferior to isolated-word training for isolated-word
recognition. PhoneBook has nearly 8000 distinct words, selected for
complete coverage of phoneme contexts enumerated using both triphones
and a novel method which takes into account syllable position, lexical
stress, and non-adjacent-phoneme coarticulatory effects. PhoneBook
consists of more than 92000 utterances, averaging over 11 talkers for
each word. A demographically-representative set of over 1300 native
speakers of American English each made a single telephone call and read
75 words. The paper describes the word list design, talker enrolment
procedure, recording procedure and equipment, utterance verification
method, and summary statistics for PhoneBook, which will be made
available through the Linguistic Data Consortium
