Abstract: In order to produce and store a pattern of reference words for use in a speaker-dependent speech recognition system, the system prompts the operator of the system to speak standard words in a predetermined sequence. For this purpose, a prestored standard word is spoken by the system with a predetermined length, power and rhythm, and the operator then repeats the standard words while attempting to simulate the same predetermined length, power and rhythm. The standard word repeated by the operator is detected and processed to determine whether it meets a certain resemblance criteria with respect to the standard word as spoken by the system. If the standard word repeated by the operator does not meet the resemblance criteria, the system repeats the same standard word to prompt the operator to try again; and, if the standard word repeated by the operator meets the resemblance criteria, it is stored as a reference word. This operation is repeated for each of the sequence of prestored standard words.

Abstract: A speech recognition system comprising a speech input device an analyzer for analyzing input speech to produce analyzed parameters and a discriminator for recognizing the input speech based on lthe analyzed parameters, has store/matching circuit at an input or output port of the analyzer for adjusting write time and read time. The store-matching circuit acts as a buffer with independent read and write addressing.

Abstract: In a floating point digital differential analyzer, multiplication and division of constants are carried out by an adder which truncates a summation SDY.sub.i of l secondary increments calculated by ##EQU1## into a third increment having an n-bit mantissa including a sign bit, and an integrator for carrying out an integration ofR.sub.i :=R.sub.i-1 +Y.sub.i .multidot..DELTA.X.sub.i -.DELTA.Z.sub.iirrespective of a value of a first increment .DELTA.X.sub.i to generate .DELTA.Z.sub.i from R.sub.i.

Abstract: In a figure displaying device which generates edge data corresponding to the individual horizontal scanning lines, to display figures on the raster scanning type Braun tube relying upon the edge data, the improvement comprising at least two sets of memory groups which have a capacity corresponding to the number of picture elements at positions of even numbers and odd numbers on the horizontal scanning lines, and which store predetermined data in the addresses corresponding to the picture elements at which edges are present, at least two converter means for converting the data read in parallel from the memory groups into series data, selection means for selecting the outputs of said converter means, and control means for displaying figures on the monitor responsive to the output of said selection means.

Abstract: A figure displaying device operates to display a plurality of fundamental figures each defined by a preset number of vectors on a display device of the raster scanning type. The figure displaying device stores the start and end point coordinates of the respective vectors of the respective fundamental figures and the gradient data of the respective vectors of the fundamental figures, and determines whether the respective vectors are located on a horizontal scanning line or not for each fundamental figure prior to the scanning operation of the horizontal scanning line. If the vectors are located on the horizontal scanning line the gradient data corresponding to the vectors on the aforementioned horizontal scanning line is read out and added to the start point coordinates thereby to renew the start point coordinates.

Abstract: A data transfer system for use in a data processing system using a direct memory access mode of operation, which is equipped with a processor, a main memory and an input/output device. The data transfer system is characterized in that, when a group of data to be transferred exists in a plurality of areas of continuous addresses of the afore-mentioned memory, a table is provided in the afore-mentioned main memory with identifying information for each group of data indicative of the first address and the number of data items to be transferred from each area of continuous addresses.

Abstract: Herein disclosed is a figure displaying device for producing and displaying a figure on a raster scan television. The figure displaying device includes first memory means for storing the vertical and horizontal coordinate values of the stop information of one frame to be displayed and second memory means for storing preset information. Further inclusive is control means for locating such dot information having a vertical coordinate value corresponding to the vertical scan of the television from the first memory means so that the dot information may be stored at the address of the second memory means corresponding to the horizontal coordinate value of the dot information located.
