    • A distributed speech recognition system and method thereof in accordance with the present invention enables a word and a natural language to be recognized using detection of a pause period in a speech period in an inputted speech signal, and various groups of recognition vocabulary (for example, a home speech recognition vocabulary, a telematics vocabulary for a vehicle, a vocabulary for call center, and so forth) to be processed in the same speech recognition system by determining the recognition vocabulary required by a corresponding terminal using an identifier of the terminal since various terminals require various speech recognition targets. In addition, various types of channel distortion occurring due to the type of terminal and the recognition environment are minimized by adapting them to a speech database model using a channel estimation method so that the speech recognition performance is enhanced.
    • 根据本发明的分布式语音识别系统及其方法使得能够使用输入的语音信号中的语音周期中的暂停时段的检测来识别单词和自然语言,以及各种识别词汇组(例如, 家庭语音识别词汇,用于车辆的远程信息处理词汇表,呼叫中心的词汇表等)在同一语音识别系统中通过使用终端的标识符来确定相应终端所需的识别词汇,因为各种 终端需要各种语音识别目标。 此外,通过使用信道估计方法使它们适应于语音数据库模型,使得由于终端类型和识别环境而发生的各种类型的信道失真被最小化,从而增强了语音识别性能。

    • A speech recognition system comprises: a speech pickup element for picking up speech from an external speaker; a speech level controller for receiving the picked up speech at a speech input level provided by a speech recognizer, and outputting the received speech to the speech recognizer; a speech detector for detecting a speech signal period needed for speech recognition from the speech output from the speech receiver; a speech saturation detector for determining, based on the threshold value, whether the speech signal in the detected speech signal period is saturated; and an input level determiner for determining a new speech input level, and outputting information on the new speech input level to the speech receiver when the speech signal in the speech signal period is saturated, whereby the speech receiver receives the speech in a unsaturated state. A speech recognition method comprises steps corresponding to the functions of the system as specified above.
    • 语音识别系统包括:用于从外部扬声器拾取语音的语音拾取元件; 语音级控制器,用于在由语音识别器提供的语音输入电平上接收所拾取的语音,并将接收的语音输出到语音识别器; 语音检测器,用于从语音接收器输出的语音中检测语音识别所需的语音信号周期; 语音饱和检测器,用于基于所述阈值来确定所检测到的语音信号周期中的语音信号是否饱和; 以及用于确定新的语音输入电平的输入电平确定器,并且当语音信号周期中的语音信号饱和时,将关于新的语音输入电平的信息输出到语音接收机,由此语音接收机接收不饱和状态的语音。 语音识别方法包括与上述系统的功能相对应的步骤。
