Abstract: A method of (and concomitant computer software embodied on a non-transitory computer-readable medium for) generating speech comprising receiving a mel-frequency cepstrum employing a set of weighting functions, generating a pseudo-inverse of the set, reconstructing a speech waveform from the cepstrum and the pseudo-inverse, and outputting sound corresponding to the waveform. Also a corresponding method of (and concomitant computer software embodied on a non-transitory computer-readable medium for) encoding speech comprising receiving sounds comprising speech, computing mel-frequency cepstral coefficients from the sounds using a quantization method selected from the group consisting of non-uniform scalar quantization and vector quantization, and generating and storing codewords from the coefficients that permit recreation of the sounds.

Abstract: A system and method of capturing, storing, editing and outputting multi-track motion data in a continuous stream on a computer with deterministic timing, where the length of the motion dataset is not limited by computer Random Access Memory. A hard real time periodic motion task takes in data streams from sensors or other computers, stores it in a shared memory area, and streams out the data to other computers so as to actuate motion. A shared memory area stores buffers and flags which indicate what data should be swapped to and from persistent storage. A soft real time periodic task transfers data pages between RAM and persistent storage based on requests from the motion task. Three data pages surround the active point in the motion dataset, four pages are reserved for copying whole blocks of data, and three pages are reserved for data editing. These ten active memory pages define a fixed memory footprint which can handle a deterministic data stream of effectively infinite length.
