1952Jrnl. Acoustical Soc. Amer. XXIV. 637 The recognizer discussed will automatically recognize telephone-quality digits spoken at normal speech rates by a single individual, with an accuracy varying between 97 and 99 percent. 1958Listener 11 Dec. 984/2 One aspect of this work..is that of Drs. Ahmed and Fatehchand..on the direct recognition of the spoken word [by a computer]... It is safe to predict that a recognizer of 95 per cent. accuracy could be built within five years. 1973Physics Bull. May 281/1 Ideally the recognizer should perform this action irrespective of the speaker and the acoustic environment in which he is speaking. This means that the machine not only has to recognize the speech sounds it receives, but it also has to ignore those facets of the signal that convey information irrelevant to the task of recognizing the speech. 1976W. A. Ainsworth Mechanisms of Speech Recognition x. 104 An automatic speech recognizer may be defined as any mechanism, other than the human auditory system, which decodes the acoustic signal produced by the human voice into a sequence of linguistic units which contain the message that the speaker wishes to convey. Ibid. 111 If the world of discourse of the speech recognizer is sufficiently restricted it is sometimes possible to employ semantic information to choose between words or phrases which seem equally likely on phonetic, syntactic or other grounds. |
