18、,drink,date,dunk”等,都会被激等,都会被激活。这些激活的词构成一个活。这些激活的词构成一个“股股”;这些交股的词是在一个目;这些交股的词是在一个目标词的声学信息的基础上提取的,并没有受到其他层面的分析标词的声学信息的基础上提取的,并没有受到其他层面的分析所影响。一个交股结构产生后,词辨认的第二个阶段就开始了。所影响。一个交股结构产生后,词辨认的第二个阶段就开始了。在第二阶段里,所有可能的信息都会影响目标词的选择,这些在第二阶段里,所有可能的信息都会影响目标词的选择,这些交互作用的信息资源都起到排除那些和交股不相似的的词的作交互作用的信息资源都起到排除那些和交股不相似的的词的作用

19、。例如进一步的声学用。例如进一步的声学/语音信息可能排除一些交股的词,如语音信息可能排除一些交股的词,如“date”和和“dunk”,而高层次的信息源也可能产生,把别而高层次的信息源也可能产生,把别的语义和句法上不合适的词,如的语义和句法上不合适的词,如“dive”和和“drink”,加,加以排除。最后才辨认到目标词。以排除。最后才辨认到目标词。(桂诗春桂诗春)25第25页,共144页,编辑于2022年,星期三26第26页,共144页,编辑于2022年,星期三vFactorsinvolvedinwordrecognition:Frequencyeffect(频率效应,词频效应)频率效应,词频效
