摘要： A method and system for synthesizing audio speech is provided. A synthesis engine receives from a host, compressed and normalized speech units and prosodic information. The synthesis engine decompresses data and synthesizes audio signals. The synthesis engine can be implemented on a digital signal processing system which can meet requirements of low resources (i.e. low power consumption, lower memory usage), such as a DSP system including an input/output module, a WOLA filterbank and a DSP core that operate in parallel.

摘要： A method and system for processing of physiological signals is provided. The system processes information signals in subband-domain associated with the physiological signals in time-domain. The information signals are obtained by one or more over-sampled filterbanks. The method and system possibly synthesizes the subband signals obtained by subband processing. The method and system may implement the analysis, subband processing, and synthesis algorithms on over-sampled filterbanks, which are implemented on ultra low-power, small size, and low-cost platform in real-time. The method and system may use over-sampled, Weighted-Overlap Add (WOLA) filterbanks.

摘要： Method and system for real-time speech recognition is provided. The speech algorithm runs on a platform having an input-output processor and a plurality of processor units. The processor units operate substantially in parallel or sequentially to perform feature extraction and pattern matching. While the input-output processor creates a frame, the processor units execute the feature extraction and the pattern matching. Shared memory is provided for supporting the parallel operation.
