Data Processing: Speech Signal Processing, Linguistics, Language Translation, And Audio Compression/decompression > Speech Signal Processing > For Storage Or Transmission > Analysis By Synthesis Analysis By SynthesisAnalysis By Synthesis patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.11/30/06 - 20060271355 - Sub-band voice codec with multi-stage codebooks and redundant coding Techniques and tools related to coding and decoding of audio information are described. For example, redundant coded information for decoding a current frame includes signal history information associated with only a portion of a previous frame. As another example, redundant coded information for decoding a coded unit includes parameters for ... 06/15/06 - 20060129390 - Apparatus and method for remotely diagnosing laryngeal disorder/laryngeal state using speech codec Provided is an apparatus and method for remotely diagnosing laryngeal disorder/laryngeal state by using the speech codec. The apparatus provides a remote larynx diagnosing apparatus and method deciding laryngeal disorder/laryngeal state by using parameters, such as a Linear Prediction Coefficient (LPC) and a pitch, which are transmitted from a system ... 10/13/05 - 20050228655 - Real-time objective voice analyzer The present invention provides a method and an apparatus for real time objective voice analysis. The apparatus includes a sound quality analyzer for receiving at least one first signal and providing at least one second signal indicative of at least one non-intrusive estimate of a sound quality based on the ... 10/13/05 - 20050228654 - Method and apparatus for improved bit rate efficiency in wavelet based codecs by means of subband correlation An encoder (1600) and decoder (1700) for improving bit rate efficiency in a wavelet based codec includes an analysis filter bank (1601) for decorrelating the input data signal. A set of decimators (1701) are used to down sample the filtered input data signal and a predictor (1705) is used to ... 08/25/05 - 20050187762 - Speech decoder, speech decoding method, program and storage media A code separation/decoding unit restores a vocal tract characteristic sp1 and a vocal source signal r1. A vocal tract characteristic modification unit modifies the vocal tract characteristic sp1 and outputs the modified vocal tract characteristic sp2. In this method, an emphasized vocal tract characteristic sp2 is generated to output by ... ### FreshPatents.com Support |
