摘要： A sound analysis apparatus employs tone models which are associated with various fundamental frequencies and each of which simulates a harmonic structure of a performance sound generated by a musical instrument, then defines a weighted mixture of the tone models to simulate frequency components of the performance sound, further sequentially updates and optimizes weight values of the respective tone models so that a frequency distribution of the weighted mixture of the tone models corresponds to a distribution of the frequency components of the performance sound, and estimates the fundamental frequency of the performance sound based on the optimized weight values.

摘要： A cordless station is operable in a local mode when it is in a local area and in a global mode when it is outside of the local area. The cordless station is assigned a telephone number of a cellular mobile telephone network (CMTN) for establishing a connection therewith when it is operating in the global mode. A memory is provided for storing the cellular telephone number. A controller is connected to a public switched telephone network (PSTN) to receive an incoming call and forwards it to the cordless station when the latter is operating in the local mode, and operates a telephone answering unit to record a message of the call if the cordless station is operating in the global mode. When a message is recorded, the controller originates a call to the PSTN using the telephone number stored in the memory to establish a connection through the PSTN and CMTN networks to the cordless station operating in the global mode. A prerecorded announcement is then sent to the cordless station via the established connection indicating that a message has been recorded in the telephone answering unit. Preferably, the controller then operates the telephone answering unit to reproduce the recorded message and transmits it to the cordless station.

摘要： An unknown word is additionally registered in a speech recognition dictionary by utilizing a correction result, and a new pronunciation of the word that has been registered in a speech recognition dictionary is additionally registered in the speech recognition dictionary, thereby increasing the accuracy of speech recognition. The start time and finish time of each phoneme unit in speech data corresponding to each phoneme included in a phoneme sequence acquired by a phoneme sequence converting section 13 are added to the phoneme sequence. A phoneme sequence extracting section 15 extracts from the phoneme sequence a phoneme sequence portion composed of phonemes existing in a segment corresponding to the period from the start time to the finish time of the word segment of the word corrected by a word correcting section 9 and the extracted phoneme sequence portion is determined as the pronunciation of the corrected word. An additional registration section 17 combines the corrected word with the pronunciation determined by a pronunciation determining section 16 and additionally registers the combination as new word pronunciation data in the speech recognition dictionary 5 if it is determined that a word obtained after correction has not been registered in the speech recognition dictionary 5. The additional registration section 17 additionally registers the pronunciation determined by the pronunciation determining section 16 as another pronunciation of the corrected word if it is determined that the corrected word has been registered.

摘要： There is provided a singing synthesis parameter data estimation system that automatically estimates singing synthesis parameter data for automatically synthesizing a human-like singing voice from an audio signal of input singing voice. A pitch parameter estimating section 9 estimates a pitch parameter, by which the pitch feature of an audio signal of synthesized singing voice is got closer to the pitch feature of the audio signal of input singing voice based on at least both of the pitch feature and lyric data with specified syllable boundaries of the audio signal of input singing voice. A dynamics parameter estimating section 11 converts the dynamics feature of the audio signal of input singing voice to a relative value with respect to the dynamics feature of the audio signal of synthesized singing voice, and estimates a dynamics parameter, by which the dynamics feature of the audio signal of synthesized singing voice is got close to the dynamics feature of the audio signal of input singing voice that has been converted to the relative value.
