    摘要: 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.

    摘要: 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:s(f)=X(f)-k(f).N(f)-d(f).

    摘要: 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.
