Data Processing: Speech Signal Processing, Linguistics, Language Translation, And Audio Compression/decompression > Speech Signal Processing > For Storage Or Transmission > Frequency > Specialized Information > Pitch > Voiced Or Unvoiced Voiced Or UnvoicedVoiced Or Unvoiced 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 - 20060247922 - System for improving speech quality and intelligibility A system and method are provided for improving the quality and intelligibility of speech signals. The system and method apply frequency compression to the higher frequency components of speech signals while leaving lower frequency components substantially unchanged. This preserves higher frequency information related to consonants which is typically lost to ... 10/26/06 - 20060241938 - System for improving speech intelligibility through high frequency compression A speech enhancement system that improves the intelligibility and the perceived quality of processed speech includes a frequency transformer and a spectral compressor. The frequency transformer converts speech signals from the time domain to the frequency domain. The spectral compressor compresses a pre-selected portion of the high frequency band and ... 08/31/06 - 20060195316 - Voice detecting apparatus, automatic image pickup apparatus, and voice detecting method A voice detecting apparatus includes a first determining unit to determine that human voice has been input if a signal component having a harmonic structure is detected from an input voice signal; a second determining unit to determine that human voice has been input if a frequency center-of-gravity of the ... 04/13/06 - 20060080089 - Circuit arrangement and method for audio signals containing speech An audio processing system includes a speech detector that receives and processes an audio input signal to determine if the input signal includes components indicative of speech, and provides a control signal indicative of whether or not the audio input signal includes speech. A speech processing device receives the audio ... 04/06/06 - 20060074640 - Method of enhancing quality of speech and apparatus thereof The present invention relates to enhancing a quality of speech wherein speech quality degradation is reduced by removing noise from an unvoiced speech. The present invention comprises dividing an input speech into a voiced speech and an unvoiced speech, performing adaptive filtering on the voiced speech to remove a noise ... 12/29/05 - 20050288922 - Method and system for speech recognition A description is given of a speech recognition system in which a speech signal of a user is analyzed so as to recognize speech information contained in the speech signal. In a test procedure the recognition result with the most probable match is converted into a speech signal again so ... 11/03/05 - 20050246166 - Componentized voice server with selectable internal and external speech detectors A method for detecting speech utterances within a telephone call can include the steps of initializing a componentized voice server having at least one software-based speech detection routine. At least one previously established parameter can be used to discern a speech detection methodology for handling an incoming call. The software-based ... 08/11/05 - 20050177363 - Apparatus, method, and medium for detecting voiced sound and unvoiced sound An apparatus, method, and medium for detecting a voiced sound and an unvoiced sound. The apparatus includes a blocking unit for dividing an input signal into block units; a parameter calculator for calculating a first parameter to determine the voiced sound and a second parameter to determine the unvoiced sound ... 08/11/05 - 20050177362 - Information detection device, method, and program In an information detecting apparatus (1), a speech kind discrimination unit (11) discriminates and classifies an audio signal at an information source into kind (category) such as music or speech, etc. on a predetermined time basis, and a memory unit/recording medium (13) records discrimination information thereof. A discrimination frequency calculating ... 08/04/05 - 20050171768 - Detection of voice inactivity within a sound stream A method for identifying end of voiced speech within an audio stream of a noisy environment employs a speech discriminator. The discriminator analyzes each window of the audio stream, producing an output corresponding to the window. The output is used to classify the window in one of several classes, for ... 06/30/05 - 20050143980 - Method and apparatus for high performance low bit-rate coding of unvoiced speech A low-bit-rate coding technique for unvoiced segments of speech, without loss of quality compared to the conventional Code Excited Linear Prediction (CELP) method operating at a much higher bit rate. A set of gains are derived from a residual signal after whitening the speech signal by a linear prediction filter. ... 06/30/05 - 20050143979 - Variable-frame speech coding/decoding apparatus and method There is provided a speech coding/decoding apparatus and method, in which the input speech signals are classified into several classes in accordance with characteristics of the input speech signals and the input speech signals are coded using frame sizes, quantizer structures, and bit assignment methods corresponding to the determined classes, ... 06/30/05 - 20050143978 - Speech detection system in an audio signal in noisy surrounding A method of detecting speech in an audio signal comprises a step of obtaining information on the energy of the audio signal, the energy information then being used to detect speech in the audio signal. The method further comprises a step of obtaining information on the voicing of the audio ... ### FreshPatents.com Support |
