摘要： In a voice authentication apparatus, a characteristics analyzer analyzes characteristics of a sample noise which is generated around a subject while the subject generates a sample voice for authentication of the subject. A setting part sets a correction value according to the characteristics of the sample noise analyzed by the characteristics analyzer. A correction part corrects an index value, which indicates a degree of similarity between a feature quantity of a reference voice which has been previously registered and a feature quantity of the sample voice obtained from the subject, based on the set correction value. A determinator determines authenticity of the subject by comparing the corrected index value with a predetermined threshold value.

摘要： A similarity degree estimation method is performed by two processes. In a first process, an inter-band correlation matrix is created from spectral data of an input voice such that the spectral data are divided into a plurality of discrete bands which are separated from each other with spaces therebetween along a frequency axis, a plurality of envelope components of the spectral data are obtained from the plurality of the discrete bands, and elements of the inter-band correlation matrix are correlation values between the respective envelope components of the input voice. In a second process, a degree of similarity is calculated between a pair of input voices to be compared with each other by using respective inter-band correlation matrices obtained for the pair of the input voices through the inter-band correlation matrix creation process.

摘要： A voice processing apparatus has a storage device that stores registration information containing a characteristic parameter of a given voice. The voice processing apparatus is further provided with a judgment unit, a management unit and a notification unit. The judgment unit judges whether an input voice is appropriate or not for creating or updating the registration information based on a degree of a difference between an inter-band correlation matrix of an input voice acquired this time and an inter-band correlation matrix of another input voice that is judged as being appropriate last time. The management unit creates or updates the registration information based on a characteristic parameter of the input voice when the judgment unit judges that the input voice is appropriate. The notification unit notifies a speaker of the input voice when the judgment unit judges that the input voice is inappropriate.

摘要： In a biometrics authentication apparatus, a storage part stores a dictionary containing biometrics information of a registered person. An information acquisition part acquires biometrics information of a subject person. An authentication part authenticates validity of the subject person based on an index representing a degree of similarity between the biometrics information of the dictionary stored in the storage part and the acquired biometrics information. A dictionary management part updates the dictionary based on the acquired biometrics information in a first case where the index represents a degree of the similarity higher than a first threshold value, and otherwise creates a new dictionary based on the acquired biometrics information and stores the created new dictionary in the storage part, in a second case where the index represents a degree of the similarity lower than the first threshold value and higher than a second threshold value which is set lower than the first threshold value.

摘要： In a sound effect applying apparatus, an input part frequency-analyzes an input signal of sound or voice for detecting a plurality of local peaks of harmonics contained in the input signal. A subharmonics provision part adds a spectrum component of subharmonics between the detected local peaks so as to provide the input signal with a sound effect. An output part converts the input signal of a frequency domain containing the added spectrum component into an output signal of a time domain for generating the sound or voice provided with the sound effect.

摘要： Microphones are provided at an air inlet of the engine and a vehicle-cabin-side wall surface of an engine room, and engine sounds are picked up. The engine sound is processed by a signal processing section, and the processed engine sound is output from a speaker provided in a vehicle cabin. The signal processing section is provided with a filter which simulates a sound insulation characteristic of the vehicle cabin and a transformation section for processing the engine sound according to driving condition. A spectrum transformation characteristic of the transformation section is determined according to values detected by a vehicle speed sensor, an engine speed sensor, and an accelerator depression sensor, and a spectrum of the engine sound is transformed by means of specification of the spectrum transformation characteristic, thereby enhancing an engine sound.

摘要： An apparatus is constructed for converting an input voice signal into an output voice signal according to a target voice signal. In the apparatus, an input device provides the input voice signal composed of original sinusoidal components and original residual components other than the original sinusoidal components. An extracting device extracts original attribute data from at least the sinusoidal components of the input voice signal. The original attribute data is characteristic of the input voice signal. A synthesizing device synthesizes new attribute data based on both of the original attribute data derived from the input voice signal and target attribute data being characteristic of the target voice signal composed of target sinusoidal components and target residual components other than the sinusoidal components. The target attribute data is derived from at least the target sinusoidal components. An output device operates based on the new attribute data and either of the original residual component and the target residual component for producing the output voice signal.
