    • The speed of an input speech is changed without any change of the pitch of the input speech. Raw data of a speech are stored so that the speed of the speech can be modulated continuously on the basis of the raw data of the speech. In the speech speed conversion method, a speech speed conversion process for the input speech is carried out in a period designated when speech speed conversion is needed, which the speech speed conversion is not carried out in the other period. Further, in the speech speed conversion apparatus having a unit for inputting a speech, a speech speed conversion unit for changing the speed of the input speech, and a unit for supplying the output of the speech speed conversion unit as an output speech to listener's ears, the apparatus further includes a speech speed conversion switch, and a unit for outputting a speech while changing the speech speed of the input speech in a period in which the speech speed conversion switch is turned on, but for outputting a speech without any change of the input speech in the other period in which the speech speed conversion switch is turned off.
    • 改变输入语音的速度,而不改变输入语音的音高。 存储语音的原始数据,使得可以基于语音的原始数据连续地调制语音的速度。 在语音速度转换方法中,在需要语音速度转换时指定的时间段中进行用于输入语音的语音速度转换处理,而在另一个周期中不执行语音速度转换。 此外,在具有用于输入语音的单元的语音速度转换装置中,用于改变输入语音的速度的语音速度转换单元和用于将语音速度转换单元的输出作为输出语音提供给听众的耳朵的单元 该装置还包括语音速度转换开关,以及用于在语音速度转换开关导通的时段中改变输入语音的语音速度而输出语音的单元,但是用于输出语音而不改变语音 在语音速度转换开关关闭的另一周期中的输入语音。

    • A speech recognition apparatus has a speech input unit for inputting a speech; a speech analysis unit for analyzing the inputted speech to output the time series of a feature vector; a candidates selection unit for inputting the time series of a feature vector from the speech analysis unit to select a plurality of candidates of recognition result from the speech categories; and a discrimination processing unit for discriminating the selected candidates to obtain a final recognition result. The discrimination processing unit includes three components in the form of a pair generation unit for generating all of the two combinations of the n-number of candidates selected by said candidate selection unit, a pair discrimination unit for discriminating which of the candidates of the combinations is more certain for each of all .sub.n C.sub.2 -number of combinations (or pairs) on the basis of the extracted result of the acoustic feature intrinsic to each of said candidate speeches, and a final decision unit for collecting all the pair discrimination results obtained from the pair discrimination unit for each of all the .sub.n C.sub.2 -number of combinations (or pairs) to decide the final result. The pair discrimination unit handles the extracted result of the acoustic feature intrinsic to each of the candidate speeches as fuzzy information and accomplishes the discrimination processing on the basis of fuzzy logic algorithms, and the final decision unit accomplishes its collections on the basis of the fuzzy logic algorithms.

    • An object of the present invention is to provide a user interface method and a device capable of arbitrarily and efficiently performing the dialog through the speech input in an in-vehicle information service system, and a system configuration which can cope with network connection loss with a center is also provided. In addition, the present invention provides the system configuration in which access from a terminal to the center is not always performed but can be performed arbitrarily according to needs. As a terminal-side configuration, a flexible dialog management unit and a task management unit for performing application management are separated from each other. Furthermore, the terminal configuration has a four-tier structure of a user interface, dialog management, task management, and applications. In addition, means for fetching application information from the center in accordance with needs is provided.
