On the basis of the information transmitted from the user unit and current time information obtained from a time keeping unit of the service center, the service center similarly creates a one-time password and an operation permission command and transmits them to the user unit. The user unit compares the two one-time passwords. When the two one-time passwords match each other, the user-requested operation (playback) is executed.

Abstract: The invention relates to a method and apparatus for recognition processing of continuous words of a group which is structured by a plurality of words such that a recognition result of all of the words which structures the continuous words is effectively and accurately confirmed. All of the continuous words which have been input are recognition processed, the recognition result of all of the continuous words is output, a response from a speaker showing an affirmative/negative recognition result is input and recognition processed. If affirmative is determined, the recognition result at that time is confirmed for all of the continuous words. If negative is determined, for each word from a first to an nth (third in this case) which structures continuous words, the content showing affirmative/negative from the speaker is recognized, affirmative or negative is determined, and the recognition result at that time is confirmed as a recognition processing target word.

Abstract: This invention concerns obtaining high recognition capability while there is a large limitation on memory capacity and processing ability of a CPU. When several words are selected as registration words among a plurality of recognizable words, a recognition target speaker speaks the respective registration words, registration word data for the respective registration words from the sound data is created and saved in a RAM. When the recognition target speaker speaks a registration word, sound is recognized using the registration word data, and when recognizable words other than the registration words are recognized, sound is recognized using specific speaker group sound model data. Furthermore, speaker learning processing is performed using the registration word data and the specific speaker group sound model data, and when recognizable words other than the registration words are recognized, sound is recognized using post-speaker learning data for speaker adaptation.

Abstract: A voice model learning data creation method and apparatus makes possible the creation of an inexpensive voice model in a short period of time when creating a voice model for a new word not in a preexisting database. Verbal data from several persons is selected from among the verbal data held in the database. This selected verbal data is referred to as standard speaker data, and is stored in a standard speaker data storage component. The remaining verbal data in the preexisting database is designated as learning speaker data, as is stored in a learning speaker data storage component. A data conversion function from the standard speaker data space to the learning speaker data space is derived. Then, the learning data for the new word is created by the data conversion function. Thus, the data which is obtained from the standard speaker speaking the new word is converted to the learning speaker data space.
