Filed:

Dec 6, 1999

Appl. No.:

09/455063

Inventors:

Jayesh S. Patel - Lowell MA 01851
Douglas E. Kolb - Bedford MA 01730

International Classification:

G10L 1904

US Classification:

704207, 704219, 704220, 704222, 704223

Abstract:

A method and apparatus for reducing the complexity of linear prediction analysis-by-synthesis (LPAS) speech coders. The method and apparatus include product code vector quantization (PCVQ) of multi-tap pitch predictor coefficients, which reduces the search and quantization complexity of an adaptive codebook. The pitch predictor vector quantizes the predictor parameters using at least two codebooks, which are effectively subcodebooks of the pitch predictor adaptive codebook. Further included is a procedure for generating and selecting code vectors consisting of ternary (1,0,-1) values, for optimizing a fixed codebook. The fixed codebook makes a single pass derivation of pulse position in the excitation signal. Serial optimization of the adaptive codebook first and then the fixed codebook, produces a low complexity LPAS speech coder of the present invention.

US Classification:

414783, 414936, 414941

Abstract:

A method and apparatus for transferring a substrate is provided. In one embodiment, an apparatus for transferring a substrate includes at least one end effector. A disk is rotatably coupled to the end effector. The disk is adapted to rotate the substrate relative to the end effector. The end effector may additionally include a sensor coupled thereto. The sensor is adapted to detect an indicia of orientation of the substrate supported by the end effector. In another embodiment, a method for transferring a substrate includes rotating the substrate disposed on an end effector and detecting an indicia of orientation of the substrate.

US Classification:

704223, 704220, 704222

Abstract:

A method and apparatus for reducing the complexity of linear prediction analysis-by-synthesis (LPAS) speech coders. The speech coder includes a multi-tap pitch predictor having various parameters and utilizing an adaptive codebook subdivided into at least a first vector codebook and a second vector codebook. The pitch predictor removes certain redundancies in a subject speech signal and vector quantizes the pitch predictor parameters. Further included is a source excitation (fixed) codebook that indicates pulses in the subject speech signal by deriving corresponding vector values. Serial optimization of the adaptive codebook first and then the fixed codebook produces a low complexity LPAS speech coder of the present invention.
