摘要： A method and system for reducing perplexity in a speech recognition system based upon determined geographic location. In a mobile speech recognition system which processes input frames of speech against stored templates representing speech, a core library of speech templates is created and stored representing a basic vocabulary of speech. Multiple location-specific libraries of speech templates are also created and stored, each library containing speech templates representing a specialized vocabulary for a specific geographic location. The geographic location of the mobile speech recognition system is then periodically determined utilizing a cellular telephone system, a geopositioning satellite system or other similar systems and a particular one of the location-specific libraries of speech templates is identified for the current location of the system. Input frames of speech are then processed against the combination of the core library and the particular location-specific library to greatly enhance the accuracy and efficiency of speech recognition by the system. Each location-specific library preferably includes speech templates representative of location place names, proper names, and business establishments within a specific geographic location.
摘要翻译：一种用于基于确定的地理位置减少语音识别系统中的困惑的方法和系统。在针对表示语音的存储模板处理输入语音帧的移动语音识别系统中，创建并存储代表语音的基本词汇表的语音模板的核心库。还创建和存储多个位置特定的语音模板库，每个库包含表示特定地理位置的专门词汇表的语音模板。然后，利用蜂窝电话系统，地理定位卫星系统或其他类似系统周期性地确定移动语音识别系统的地理位置，并为该系统的当前位置识别特定位置的语音模板库。然后根据核心库和特定位置特定库的组合对输入的语音帧进行处理，以大大增强系统语音识别的准确性和效率。每个位置特定的图书馆优选地包括表示特定地理位置内的位置地名，专有名称和商业场所的语音模板。
