Speaker adaptive learning of resonance targets in a hidden trajectory model of speech coarticulation
Patent number: 7519531Abstract: A computer-implemented method is provided for training a hidden trajectory model, of a speech recognition system, which generates Vocal Tract Resonance (VTR) targets.

The CPU 15 also re-arrays the picture data stored in the memory card 13 in the sequence of the decreasing magnitude of the feeling model output.Type: GrantFiled: April 1, 2005Date of Patent: December 19, 2006Assignee: Sony CorporationInventors: Kotaro Sabe, Masahiro Fujita

Patent number: 7149603Abstract: A robot apparatus is provided. A CPU 15 determines an output of a feeling model based on signals supplied from a touch sensor 20. The CPU 15 also deciphers whether or not an output value of the feeling model exceeds a pre-set threshold value. If the CPU finds that the output value exceeds the pre-set threshold value, it verifies whether or not there is any vacant area in a memory card 13.

Patent number: 7136876Abstract: A method and apparatus for building an abbreviation dictionary involves searching through a set of source documents. The abbreviations having likely definitions are identified and the definitions extracted from the document. The definitions having identical associated abbreviations are grouped together. The definition groups are each arranged into clusters based on an n-gram or other combinatorial method to determine similar definition. Further disambiguation is provided by looking at similarity between clusters using an annotation associated with the source documents from which the definitions were extracted.Type: GrantFiled: March 3, 2003Date of Patent: November 14, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: Eytan Adar, Lada A.

Patent number: 7124077Abstract: A method and system of performing postfiltering in the frequency domain to improve the quality of a speech signal, especially for synthesized speech resulting from codecs of low bit-rate, is provided. The method comprises LPC tilt computation and compensation methods and modules, a formant filter gain computation method and module, and an anti-aliasing method and module. The formant filter gain calculation employs an LPC representation, an all-pole modeling, a non-linear transformation and a phase computation. The LPC used for deriving the postfilter may be transmitted from an encoder or may be estimated from a synthesized or other speech signal in a decoder or receiver. The invention may be implemented in a linked decoder and encoder. A separate LPC evaluation unit that is responsible for processing and or deriving the LPC may be implemented within the invention.Type: GrantFiled: January 28, 2005Date of Patent: October 17, 2006Assignee: Microsoft CorporationInventors: Hong Wang, Vladimir Cuperman, Allen Gersho, Hosam A.

Method and system for the automatic segmentation of an audio stream into semantic or syntactic units
Patent number: 7120575Abstract: A digitized speech signal (600) is input to an F0 (fundamental frequency) processor that computes (610) a continuous F0 data from the speech signal. By the criterion voicing state transition (voiced/unvoiced transitions) the speech signal is presegmented (620) into segments. For each segment (630) it is evaluated (640) whether F0 is defined or not defined i.e. whether F0 is ON or OFF. In case of F0=OFF a candidate segment boundary is assumed as described above and, starting from that boundary, prosodic features are computed (650). The feature values are input into a classification tree and each candidate segment is classified thereby revealing, as a result, the existence or non-existence of a semantic or syntactic speech unit.Type: GrantFiled: August 2, 2001Date of Patent: October 10, 2006Assignee: International Business Machines CorporationInventors: Martin Haase, Werner Kriechbaum, Gerhard Stenzel -
