PSoC BASED SPEECH RECOGNITION SYSTEM

摘要: Speech Recognition Systems(SRS) have been implemented by various processors including the digital signal processors(DSPs) and field programmable gate arrays(FPGAs) their performance has reported in literature. The fundamental purpose of speech is communication, i.e., transmission messages.In case speech, analog form message an acoustic waveform, which we call signal. signals can be converted to electrical waveform a microphone, further manipulated both processing, then back loudspeaker, telephone handset or headphone, as desired.The recognition requires feature extraction classification. systems that use input require microcontroller carry out desired actions. In this paper, Cypress Programmable System on Chip (PSoC) studied used for implementation SRS. From all available PSoCs, PSoC5 containing ARM Cortex-M3 its CPU used. noise are firstly nullified from using LogMMSE filtering. These sent wherein recognized actions performed.
