基于单片机可语音控制和报时的数字时钟的设计

以STC89C516单片机为主机,STC11L08XE单片机为从机,在传统按键控制式数字时钟的基础上加入语音识别模块和语音合成模块,实现了可语音控制和语音报时的功能。该时钟除具有计时功能外,还具有整点报时、询问报时和闹钟功能;既可用按键控制,也可通过人机对话的形式语音控制。经测试,语音识别率可达75%。不仅适用于广场、车站、客厅等公共场所,也适用于卧室等私人空间。

With STC89C516 as the host and STC11L08XE as the slave,the automatic speech recognition (ASR) module and the text to speech module are added to the traditional key-controlled digital clock to realize the function of speech control and voice time reporting.The clock not only has timing function,but also has the hourly chime,give current time and alarm function.The clock can be controlled by either keyboard or voice in the form of a human-machine dialogue.After testing,the speech recognition rate can reach 75%.It is not only suitable for use in public places such as squares,stations,living rooms,but also in private spaces such as bedrooms.
