Speech Processing has rapidly emerged as one of the most widespread and well-understood application areas in the broader discipline of Digital Signal Processing. Besides the telecommunications applications that have hitherto been thelargest users of speech processing algorithms, several non-traditional embedded processor applications are enhancing their functionality and user interfaces by utilizing various aspects of speech processing. 'Speech Processing in Embedded Systems' describes several areas of speech processing, and the various algorithms and industry standards that address each of these areas. The topics covered include different types of Speech Compression, Echo Cancellation, Noise Suppression, Speech Recognition and Speech Synthesis. In addition this book explores various issues and considerations related to efficient implementationof these algorithms on real-time embedded systems, including the role played by processor CPU and peripheral functionality. Provides insight into the role of speech-compression techniques in a variety of embedded applications Discusses the advantages and technical considerations associated with incorporating speech-compression algorithms into specific embedded applications Discusses a broad range of popular speech processing algorithms, including several speech compression techniques as well as other key areas such as speech recognition, noise suppression, echo cancellation and speech synthesis Provides an overview of CPU architecture and peripheral considerations for executing speech processing techniques in embedded processing environments Serves as a primer on the application of speech processing for embedded system designers who are otherwise new to the area of Digital Signal Processing but are considering incorporating speech communication, recording, playback, synthesis or recognition capabilities in their application INDICE: Preface.- Introduction.- Signal Processing Fundamentals.- Basic Speech Processing Concepts.- CPU Architectures for Speech Processing.- Peripherals for Speech Processing.- Speech Compression Overview.- Voice Coders.- Noise and Echo Cancellation.- Speech Recognition.- Speech Synthesis.- Conclusion.
