ABSTRACT This study investigates the e ect of di erent external and middle ear models as the preemphasis lter for speech recognition. We nd that an external and middle ear model derived from physiological data of human auditory systems gives the highest recognition rate. This auditory based preemphasis lter also gives good a recognition rate for the consonant sounds (fricatives, stops, liquids and diphthongs).

Allophone-based acoustic modeling for Persian phoneme recognition
Phoneme recognition is one of the fundamental phases of automatic speech recognition. Coarticulation which refers to the integration of sounds, is one of the important obstacles in phoneme recognition. In other words, each phone is influenced and changed by the characteristics of its neighbor phones, and coarticulation is responsible for most of these changes. The idea of modeling the effects o...
