COMPUTER PROCESSING OF ACOUSTIC AND LINGUISTIC INFORMATION IN AUTOMATIC SPEECH RECOGNITION
Abstract
The use of computers in automatic speech recognition is discussed and equipment used in the analog to digital conversion and recording of speech wave data for processing in the computer is described. The development and construction of associated apparatus for the visual inspection of speech waves is also described; this includes the instantaneous sound spectrograph for immediate viewing of the speech wave spectrum, the continuous photographic spectrograph for obtaining a permanent record of the speech wave, and the speech microscope for detailed inspection of wave shapes and the measurement of fundamental frequencies. Finally, the report describes a computer program providing information about the distribution of English phonemes from phonetically transcribed material, and presents a statistical analysis of the results.
