摘要： 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.
摘要翻译：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。

摘要： 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.
摘要翻译：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。

摘要： A microphone apparatus for processing and outputting an output signal of a microphone array including at least nine microphones includes a directivity function processing circuit that converts the output signal of the microphone array into a unidirectional signal and that outputs the unidirectional signal. The directivity function processing circuit expands a directivity function whose variable is an incident angle of an acoustic wave into a Fourier series up to at least third order. The variable in the expanded expression is produced from output signals of the microphones forming the microphone array.

摘要： An echo canceller formed of an adaptive filter is designed such that even under a condition where a system transmission delay is undefined, an appropriate delay time can be set in a delay circuit that absorbs a system delay, and that an effective echo cancellation effect can always be achieved. A time difference of a transmission path until a reproduction audio signal input to the delay circuit is input as a processing target signal of an adaptive filter system through a space between a speaker and a microphone is determined, and the delay time corresponding to this time difference is set in the delay circuit. At this time, the speaker and the microphone are placed so that the distance therebetween is small, and the delay time of the delay circuit is set to 0. Thus, the determined time difference indicates a system transmission delay in the above transmission path. That is, an accurate delay time corresponding to the system transmission delay can be set in the delay circuit.

摘要： The present invention is intended to perform text-to-speech conversion by replacing URLs and electronic mail addresses included in the text data of electronic mail by registered predetermined words. A mail watcher application control section executes the processing for converting electronic mail received by a MAPI mailer into speech data. The mail watcher application control section outputs URLs and electronic mail addresses included in the text data of electronic mail supplied from the MAPI mailer to a URL and mail address filter to replace them by registered predetermined names. Of the entered texts, the URL and mail address filter compares the URL or mail address included in the entered text with those registered in the URL and mail address table. If a the URL or mail address of the entered text is found matching, the URL and mail address filter replace it by the registered name and outputs it to the mail watcher application control section.
