The 1976 modular acoustic processor (MAP) : Signal analysis and phonemic segmentation

The problems involved in automatic recognition of continuous speech are generally considered very difficult. In an attempt to solve these problems an acoustic processing system has been under development which has stages dedicated to signal analysis, spectral classification, phonemic segmentation, phonemic (steady state) classification, phoneme boundary placement, diadic (transitional) classification, and final phoneme string consolidation. This paper presents the concepts of and some details concerning the first five stages, through phoneme boundary placement. Performance results are also presented.
