Abstract: Voice processing for recognizing a predetermined voice such as a place name is performed by a voice processing section 14 from an audio signal inputted from a microphone 11 on the basis of an operation of a talk switch 18. When a map display is based on the recognized place name is performed, an incorrect reading and a place name commonly mistaken can be also recognized. Accordingly, a high grade operation of a navigation apparatus can be simply performed without obstructing an operator driving while a car.

Abstract: In a speech recognizing apparatus, a grammatical qualification of a proposed speech recognition result candidate is judged without using a grammatical rule. The speech recognizing apparatus for performing sentence/speech recognition is comprised of an analyzing unit for acoustically analyzing speech inputted therein to extract a feature parameter of the inputted speech; a recognizing unit for recognizing the inputted speech based upon the feature parameter outputted from said analyzing unit to thereby a plurality of proposed recognition result candidates; an example data base for storing therein a plurality of examples; and an example retrieving unit for calculating a resemblance degree between each of said plurality of proposed recognition result candidates and each of the plural examples stored in the example data base and for obtaining the speech recognition result based on said calculated resemblance degree.

Abstract: A mapping determination method for obtaining mapping F from an N-dimensional metric vector space .OMEGA..sub.N to an M-dimensional metric vector space .OMEGA..sub.M has the following steps to get the optimal mapping quickly and positively. In the first step, complete, periodic, L.sub.m basic functions g.sub.m (X) according to the distribution of samples classified into Q categories on the N-dimensional metric vector space .OMEGA..sub.N are set. In the second step, a function f.sub.m (X) indicating the m-th component of the mapping F is expressed with the linear sum of the functions g.sub.m (X) and L.sub.m coefficients c.sub.m. The third step provides Q teacher vectors T.sub.q =(t.sub.q.1, t.sub.q.2, t.sub.q.3, . . . , t.sub.q.M) (where q=1, 2, . . . , Q) for the categories on the M-dimensional metric vector space .OMEGA..sub.M, calculates the specified estimation function J, and obtains the coefficients c.sub.m which minimize the estimation function J. In the fourth step, the coefficients c.sub.

Abstract: A pattern matching multiplies distances between an input pattern and standard patterns by distance-scale correcting weight coefficients respectively prepared for the standard patterns. This yields a distance corresponding to a category shape of a standard pattern and enhance an input pattern recognition ratio. A pattern recognition apparatus stores distance-scale correcting weight coefficients respectively prepared for all standard patterns in storage means. Distances between stored standard patterns and an input pattern generated by input pattern generating means are calculated. The calculated distance is multiplied by a weight coefficient stored in the storage means in accordance with the standard pattern used for calculating the distance from the input pattern. This structure reduces the number of templates when providing the standard patterns as multiple templates and, at the same time, enhances the input pattern recognition ratio.

Abstract: A material in the form of polyamide fibers, polyester fibers, woven and non--woven fabric thereof, thermoplastic elastomer, and polyurethane sheet is coated with a silicone coating composition to a thickness of 5 to 20 .mu.m, obtaining a silicone coated base material. The silicone coating composition contains (A) an organopolysiloxane having at least two alkenyl groups, (B) an organohydrogenpolysiloxane having at least two hydrogen atoms, (C) an organic silicon compound having at least one hydrogen atom and at least one epoxy and/or trialkoxy-silyl group, (D) a carbon, NiO.sub.2, FeO, FeO.sub.2, Fe.sub.2 O.sub.3, Fe.sub.3 O.sub.4, CoO.sub.2, CeO.sub.2 or TiO.sub.2 powder having a mean particle size of up to 20 .mu.m, and (E) a platinum catalyst. The silicone coated base material is flame resistant and fully acceptable in practical use even though the silicone coating is as thin as 5 to 20 .mu.m, namely less than about one-half of the conventional coating thickness.

Abstract: A noise signal supplied from a microphone by way of an analog to digital converter is Fourier converted to calculate a power spectrum of the noise signal by a Fourier converting section. A system controller compares an average value of the power spectrum of the signal being outputted from the microphone at present and an average value of the power spectrum of a noise signal stored in a noise memory at present with each other. When the system controller determines that the difference between the average value of the power spectrum of the signal being outputted from the microphone at present and the average value of the power spectrum of the noise signal stored in the noise memory at present is higher than a predetermined reference value, it outputs a controlling signal to a sound storing and reading out section to store the signal being outputted from the microphone at present into the noise memory.

Abstract: A speech recognition system includes an acoustic analyzer which produces a time sequence of acoustic parameters from an input speech signal in an utterance boundary thereof, and estimates a trajectory in a parameter space from the time sequence of acoustic parameters. The trajectory is re-sampled in the parameter space at predetermined constant intervals sequentially each time the acoustic parameters are produced by the acoustic analyzing means, thereby producing an input utterance pattern. The input utterance pattern is matched with reference speech patterns to recognize the input speech signal. The speech recognition system also has an utterance boundary detector for detecting the utterance boundary of the input speech signal. The trajectory is re-sampled while the utterance boundary is being detected by the utterance boundary detector.

Abstract: The present fluorosilicone composition is an addition reaction curable composition that uses, as an alkenyl group-containing organopolysiloxane, a fluorine-containing organopolysiloxane represented by the following general formula (1): ##STR1## wherein R represents a vinyl group, R.sup.1 represents an alkyl group or a phenyl group, R.sup.2 represents a group represented by the following formula (2): ##STR2## in which p is an integer of 2 to 8 and q is an integer of 1 to 10, and n and m are each a positive integer. This composition can form a gellike cured product particularly excellent in acid resistance.

Abstract: A voice responsive telephone adapter, or speech recognition adapter, for use with a telephone set having for example, telephone answering capabilities. The voice responsive telephone adapter may be used to dial telephone numbers or control auxiliary functional capabilities relating the message playback, for example in response to recognized verbal commands, such as, for example, names or operational functions.
