    • 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.
    • 语音识别系统包括声学分析器,其从其语音边界中的输入语音信号产生声学参数的时间序列,并根据声学参数的时间序列估计参数空间中的轨迹。 每当由声学分析装置产生声学参数时,以预定的恒定间隔在参数空间中重新采样轨迹,从而产生输入的发音模式。 输入语音模式与参考语音模式相匹配,以识别输入语音信号。 语音识别系统还具有用于检测输入语音信号的话语边界的话语边界检测器。 当话语边界检测器检测到话语边界时,重新采样轨迹。

    • 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.
    • 模式匹配通过分别为标准模式准备的距离尺度校正权重系数来乘以输入模式和标准模式之间的距离。 这产生与标准图案的类别形状相对应的距离,并增强输入模式识别率。 模式识别装置存储分别为存储装置中的所有标准模式准备的距离尺度校正权重系数。 计算存储的标准图案与由输入图案生成装置生成的输入图案之间的距离。 根据用于计算与输入图案的距离的标准图案,将计算出的距离乘以存储在存储装置中的加权系数。 当将标准图案提供为多个模板时,该结构减少了模板的数量,并且同时增强了输入模式识别率。

    • 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. Consequently, the signal being outputted from the microphone at present is stored into the noise memory in place of the noise signal stored in the noise signal at present.
    • 通过模数转换器从麦克风提供的噪声信号被傅里叶变换,以通过傅里叶变换部分计算噪声信号的功率谱。 目前,系统控制器将目前从麦克风输出的信号的功率谱的平均值和当前存储在噪声存储器中的噪声信号的功率谱的平均值进行比较。 当系统控制器确定目前从麦克风输出的信号的功率谱的平均值与当前存储在噪声存储器中的噪声信号的功率谱的平均值之间的差异高于预定值 参考值,它将控制信号输出到声音存储和读出部分,以将当前从麦克风输出的信号存储到噪声存储器中。 因此,目前从麦克风输出的信号被代替存储在噪声信号中的噪声信号而被存储在噪声存储器中。
