摘要： In an apnea detecting apparatus, a respiratory pace analyzer determines a respiratory pace of a user based on an ambient noise (including a breathing sound, a snore, and the like of the user) generated in a surrounding area and on information of a posture of the user in determining whether or not the user suffers from the apnea syndrome. Then, an apnea time extracting unit in the apnea detecting apparatus determines whether or not a silent time is included in a time period during which the user is estimated to be breathing based on the respiratory pace and the silent time in the ambient noise.

摘要： In a pitch conversion method and device which can reduce data throughput while suppressing a degradation of sound quality due to a pitch conversion as much as possible, an input signal pitch pattern per predetermined processing unit and a target pitch pattern are inputted, and a degradation degree indicating how a waveform of the input signal degrades upon pitch conversion from the input signal pitch pattern to the target pitch pattern is calculated. Alternatively, a degradation degree corresponding to a voice state and a phonemic type of the input signal is extracted from a database in which all of combinations of voice states and phonemic types estimated are associated with the degradation degrees to be recorded. Then, a pitch converter which performs a pitch conversion with small data throughput and a pitch converter which performs a pitch conversion with large data throughput are switched over depending on the degradation degree.
