The 1976 modular acoustic processor(MAP)

The modular acoustic processor (MAP), a complex experimental system for automatic derivation of phonemic string output for continuous speech, has stages dedicated to signal analysis, spectral classification, phonemic segmentation, phonemic (steady state) classification, phoneme boundary placement, dyadic (transitional) classification, and final phoneme string consolidation. This paper presents the concepts of and some details concerning these five stages. Results on a large body of continuous speech data, prepared by an automatic evaluation system, will also be presented.
