摘　　要：在介绍超声波测距原理的基础上,设计并实现了一种基于SYN6288语音合成芯片的超声波语音测距拐杖。系统以STC89C52单片机为核心,采用高性能的KS103超声波模块,具备温度补偿功能,可以对超声波的速度进行校正。并采用语音合成芯片SYN6288对实时采集的距离信息进行转换,该芯片采用TTS技术,无需预先录音,可以直接实现文字到语音的转换,通过外置扬声器进行语音提示,实现了测量结果的语音化。实验证明,该超声波语音测距拐杖具有较高的精度和使用方便的特点,可为盲人行走提供安全的保障。On the basis of introducing the principle of ultrasonic distance measurement,this paper designs and implements an ultrasonic voice ranging walking stick based on the SYN6288 speech synthesis chip. The system takes STC89C52 single-chip microcomputer as the core and uses the high-performance KS103 ultrasonic module that with temperature compensation function,so the ultrasonic speed can be corrected. The system adopts the speech synthesis chip SYN6288 for real-time acquisition of distance information. The chip uses TTS technology which is no need to make advanced recording and can directly implement the conversion from text to speech,then the voice prompt by the external speaker is made to achieve the voiced measurement results. Experiments show that the ultrasonic voice range crutch is easy to be used with high precision,and can provide security for the blind to walk.
