An office information system having a device which provides a user with an operational message of the system is disclosed. In an embodiment of the office information system, a path record storage device stores a plurality of path records related to components of the system, each path record indicating a locating path needed to reach a location of a specific one of the components in the system when a failure related to the specific one of the components occurs. A failure location detecting device detects a location of a component in the system when a failure related to the component occurs. A reached location determining device reads a path record from the path record storage device when the location of the failure is detected, and determines a currently reached location in the system based on the path indicated by the path record. A message device generates, when the reached location is determined, an operational message needed for recovering the failure at a subsequent location in the path following the reached location.

A method and a system recognize speech based upon an approach which combines certain advantages of speech detection and word spotting for improved accuracy without sacrificing efficiency. The improved method and system is based upon the determination of a total similarity value based upon a cumulative value and power information at or substantially near a terminal frame.

Integrated endpoint detection for improved speech recognition method and

A noise eliminating apparatus includes a first feature extracting block for individually extracting a feature quantity X(f) (f =1, 2, . . . , n) of an input speech containing a noise for n channels (n is an integer), and a second feature extracting block for individually extracting a feature quantity N(f) of the noise for the n channels. The apparatus also includes a noise eliminating block for deriving a first noise eliminating variable k(f) and a second noise eliminating variable d(f) from the feature quantity X(f) of the input speech containing the noise provided for each of the n channels and the feature quantity N(f) of the noise provided for each of the n channels and for generating a feature quantity S(f) of a noise-eliminated input speech in accordance with the following formula:

Noise eliminating apparatus and speech recognition apparatus using the

A voice recognition apparatus includes a coefficient memory for storing at least one coefficient for correcting a degree of similarity which is obtained by either one of the speaker-independent recognition and the speaker-dependent recognition. The apparatus also includes a voice identification circuit for comparing the degrees of similarity of the candidates obtained by either one of the speaker-independent recognition and the speaker-dependent recognition with corrected degrees of similarity of the candidates related to the other recognition type which are obtained by performing a predetermined operation to the degree of similarity of each candidate which is supplied from the other recognition type. Then the voice identification decides one candidate having the highest degree of similarity to be an identification result.

Speech recognition method and apparatus

A voice actuated dialing apparatus has a feature extraction part for extracting a feature of an input data, a storage for storing registered standard patterns and corresponding telephone numbers of destination subscribers, a pattern matching part for comparing a standard pattern of the feature extracted by the feature extracting part with the registered standard patterns so as to recognize a predetermined one of the registered standard patterns which matches the standard pattern of the extracted feature, a speech synthesis part for outputting a speech corresponding to the predetermined standard pattern read out from the storage for confirmation of a result of the recognition, and a dialing circuit for dialing to a predetermined one of the registered telephone numbers corresponding to the predetermined standard pattern in a voice-dialing mode.
