摘要： In a signal pattern recognition apparatus, a plurality of feature transformation sections respectively transform an inputted signal pattern into vectors in a plurality of feature spaces corresponding respectively to predetermined classes using a predetermined transformation parameter corresponding to each of the classes so as to emphasize a feature of each of the classes, and a plurality of discriminant function sections respectively calculates a value of a discriminant function using a predetermined discriminant function representing a similarity measure of each of the classes for the transformed vectors in the plurality of feature spaces. Then, a selection section executes a signal pattern recognition process by selecting a class to which the inputted signal pattern belongs based on the calculated values of a plurality of discriminant functions corresponding respectively to the classes, and a training control section trains and sets a plurality of transformation parameters of the feature transformation process and a plurality of discriminant functions so that an error probability of the signal pattern recognition is minimized based on a predetermined training signal pattern.

摘要： A speech recognition unit (114) and a processor unit (116) of a foreign language learning device (100) receive sentence speech information corresponding to a sentence pronounced by a learner (2) to separate the information into word speech information on the basis of words included in the sentence. The processor unit (116) evaluates the degree of matching (likelihood) of each word speech information with a model speech, and a resultant evaluation is indicated on a display unit (120) on the basis of each word.

摘要： The present invention provides an accelerator working in place of a CPU on a motherboard to speed up the processing. The accelerator can realize the high-speed processing even when a clock on the accelerator is not an integral multiple of a clock on the CPU. When a clock frequency of a clock signal CLK on the motherboard is equal to 20 MHz and a maximum frequency of a CPU (3) on an accelerator (100) is equal to 33 MHz, for example, the CPU (3) does not work properly by a doubled clock signal. In such a case, a clock multiplication circuit (3a) multiplies the clock signal CLK by 1.5 times to generate a clock signal CLK15. There are three different patterns in the relationship between the timing of access of the CPU 3 and the timing of access of the motherboard. The accelerator of the invention determines the appropriate timing in each case and allows the access of the CPU 3 to be synchronous with the access of the motherboard.
摘要翻译：本发明提供一种用于代替主板上的CPU的加速器，以加速处理。即使加速器上的时钟不是CPU上的时钟的整数倍，加速器也可以实现高速处理。当母板上的时钟信号CLK的时钟频率等于20MHz，并且加速器（100）上的CPU（3）的最大频率等于33MHz时，CPU（3）不工作正确地通过双倍时钟信号。在这种情况下，时钟倍增电路（3a）将时钟信号CLK乘以1.5倍以产生时钟信号CLK15。在CPU 3的访问定时与主板的访问时间之间的关系中存在三种不同的模式。本发明的加速器在每种情况下确定适当的定时，并允许CPU 3的访问与主板的访问同步。
