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 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： 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： 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 sound source apparatus has a plurality of tone forming parts for outputting either of desired tones or formants according to designation of a wave table sound source mode or a voice synthesizing mode, such that the tone forming parts generate the tones in the wave table sound source mode, and generate the formants for synthesis of a voice in the voice synthesizing mode. Each tone forming part has an envelope application section that operates in the wave table sound source mode for generating an envelope signal which rises in synchronization with an instruction to start the generating of the tone and decays in synchronization with another instruction to stop the generating of the tone, and applying the generated envelope signal to waveform data read from a wave table. The envelope application section operates in the voice synthesizing mode for generating an envelope signal which rapidly decays every timing corresponding to a pitch period of the voice to be synthesized and rapidly rises after the decay, and applying the generated envelope signal to the waveform data read from a wave table.
