Data Processing: Speech Signal Processing, Linguistics, Language Translation, And Audio Compression/decompression > Speech Signal Processing > For Storage Or Transmission > Time > Silence Decision Silence DecisionSilence Decision 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.11/02/06 - 20060247925 - Virtual push-to-talk A method of implementing a virtual push-to-talk function within a multimodal interface can include presenting a multimodal interface having a voice-enabled user interface element and locating a visual identifier proximate to the voice-enabled user interface element. The visual identifier can signify that the voice-enabled user interface element is configured to ... 07/06/06 - 20060149536 - Sid frame update using sid prediction error In a packet-based multimedia communication system, such as ITU G.711, using linear prediction parameters to derive the linear prediction error of the codec. The linear prediction error is then used as a feature of the Silence Insertion Descriptor (SID) algorithm. Generating a SID frame by comparing linear prediction errors between ... 06/22/06 - 20060136201 - Hands-free push-to-talk radio A hands-free digital push-to-talk device (102) includes a digital background noise suppressor (302), a digital voice activity detector (304), an audio buffer (306), as well as a decision handler (308), embedded inside the device's (102) digital signal processor (222). Audio is buffered until the decision handler (308) determines that speech ... 05/18/06 - 20060106598 - Transmit/receive data paths for voice-over-internet (voip) communication systems The present invention is a method and apparatus in a data processing system that includes a Voice over Internet Protocol (VoIP) communication system for improving transmit and receive data paths. The communication system includes a digital signal processing unit. The digital signal processing unit includes a mandatory coder/decoder (codec) that ... 01/26/06 - 20060020449 - Method and system for generating colored comfort noise in the absence of silence insertion description packets A method and system for utilizing information content in speech and a transition hangover between speech and noise to generate comfort noise on the decoder side. This adaptation to noise may be accomplished using various algorithms of estimating the spectrum of color noise. According to an embodiment of the present ... 11/10/05 - 20050251386 - Method and apparatus for adaptive conversation detection employing minimal computation A conversation detector and detection method is based on voice band energy detection. The detector is formed of a signal preconditioner, a comparator and an analysis unit. The comparator generates signal pulses reduced in resolution and sample rate (e.g., single bit data) and indicative of energy level and/or duration of ... 11/03/05 - 20050246169 - Detection of the audio activity The invention relates to a method for detecting audio activity. In the method samples of audio signal are formed or received. A feature vector is formed from the samples of the audio signal and the feature vector is projected by a discriminant vector to form a projection value for the ... 09/29/05 - 20050216261 - Signal processing apparatus and method A signal processing apparatus and method for performing a robust endpoint detection of a signal are provided. An input signal sequence is divided into frames each of which has a predetermined time length. The presence of the signal in the frame is detected. After that, the filter process of smoothing ... ### FreshPatents.com Support |
