SPCE500A在语音遥控器中的应用

Application of SPCE500A in robot handler-controlled by speech

利用凌阳公司新一代 16位单片机SPCE5 0 0A能够快速处理复杂数字信号的特点 ,设计出一种空调器语音遥控器 .该设计依据非特定发音人识别原理 ,将经过处理的输入语音的特征参数作为未知模式 ,与预先存储的标准模式进行比较 ,通过调用SPCE5 0 0A的C函数库和语音处理函数库中的函数来实现语音识别、处理与控制 ,并采用SACMS4 80音频编码算法播放提示语音 .该遥控器用语音命令代替按键输入 ,具有更友好的人机界面和更人性化的操作方式 .

A robot handler controlled by speech in air conditioner is designed by using the newest 16 bit SPCE500A single chip developed by Sunplus Technology for processing complicated digital signals rapidly.According to the concept of speaker independent voice recognition,the processed feature parameter extraction of audio input which is utilized as unknown pattern is compared with criterion pattern of voice beforehand stored in ROM and then the function in function library of C language and of voice processing for SPCE series will be called for implementing voice recognizer,processor and controller.Audio coding algorithm of SACMS480 will be adopted and the hinted voice will be played.The ordinary key inputing is replaced by the voice command in this robot handler for more friendly man machine interface and more humanized operating mode.
