Description

一种用于家电的语音交互装置
技术领域
本实用新型涉及一种用于家电的语音交互装置。
背景技术
目前,在使用家用电器查找某一种功能时,大部分仅能通过上一个下一个这样的按键操作进行选择和功能切换,而这种操作方式在家电功能越来越复杂的情况下,尤其是目前的微波炉、冰箱、空调、彩电等功能丰富的电器,在功能上的选择多种多样,操作选择也更加复杂,采用传统的交互方式操作起来非常麻烦,尤其是对于一些老年用户来说,甚至无从下手。此外,目前家电产品的功能说明和使用指导等信息,还都是通过纸质说明书的形式提供给消费者,用户常常因为不愿看内容繁多的说明书,往往只了解和使用最常见的功能,而不会去用这些家电的高级功能,比如,虽然买了一个非常高档的多功能微波炉,却只用它来加热剩饭剩菜,而不会使用智能菜单程序来烹制菜肴,或者使用里面的光波消毒来消毒餐具等等,这样的情况使得家电的价值无法充分体现,也无法得到消费者的认可。
实用新型内容
本实用新型的目的在于提供一种能够全面实现对家电的便捷、人性化交互式操控的用于家电的语音交互装置。
为实现上述目的,本实用新型采用了以下技术方案:一种用于家电的语音交互装置,包括语音处理单元,其音频信号输入端与音频输入单元的输出端相连,其音频信号输出端与音频输出单元的输入端相连,其通讯输入输出端与家电主控单元的输入输出端相连。
由上述技术方案可知,本实用新型可通过语音处理单元实现对家电的语音搜索和语音命令,如立即找到某个特定的智能做菜程序,或一步切入某个操作命令,如“加热三分钟”,此外,在使用家电的过程中,用户还可以通过音频输出单元让家电自己“开口”读菜单列表、菜谱、操作步骤说明、使用注意事项和产品功能介绍等,通过听播报来方便的了解家电的相关信息,操作家电变得更加轻松自在。本实用新型可以帮用户通过语音实现对家电进行快捷、人性化的交互式操控。 
附图说明
图1是本实用新型的电路框图。
具体实施方式
一种用于家电的语音交互装置,包括语音处理单元1,其音频信号输入端与音频输入单元的输出端相连,其音频信号输出端与音频输出单元3的输入端相连,其通讯输入输出端与家电主控单元4的输入输出端相连。所述的语音处理单元1上设置通讯接口,语音处理单元1的通讯输入输出端通过该通讯接口与家电主控单元4的输入输出端相连,所述的通讯接口为串口或I2C接口,通讯接口用于向家电主控单元4反馈语音识别结果,从家电主控单元4获得需要播报的信息,如图1所示。 
如图1所示,所述的音频输入单元采用麦克风2,所述的音频输出单元3由音频放大电路和扬声器组成,语音处理单元1的信号输入端与麦克风2相连,语音处理单元1的信号输出端与音频放大电路的输入端相连,音频放大电路的输出端与扬声器相连,电源电路分别向语音处理单元1和音频放大电路供电。语音处理单元1的作用如下:采集并处理由用户通过麦克风2输入的语音信号;将由家电主控单元4发出的文本或代码信息合成为语音信号输出;将其内部预置的录音文件进行播放。麦克风3用于采集用户说出的语音信号,扬声器用于播报语音输出信号。
以下结合图1对本实用新型作进一步的说明。
用户通过麦克风3说出专门的语音唤醒命令来开启语音识别功能,使家电进入语音识别状态,接着,用户再发出语音控制命令,将语音控制命令传输到语音处理单元1进行语音命令的识别,语音处理单元1将识别结果发送到家电主控单元4,家电主控单元4发送提示和确认信息至语音处理单元1,通过其播报相应的语音,提示用户确认是否要执行相应的操作,用户确认后,由家电主控单元4控制相应的机电部件执行相应的工作。语音处理单元1的语音播报可选择采用TTS语音合成播报功能或预录音播报功能。
以微波炉这种家电为例,集成本装置的微波炉上电后,用户通过麦克风3说出专门的语音唤醒命令,比如用户说出“语点语点”这条语音唤醒命令,使微波炉进入语音识别状态;接着,用户再说出“加热3分钟”这条语音控制命令,语音处理单元1接收到语音控制命令后,对这条语音控制命令进行识别,将识别结果发送到微波炉的主控单元,微波炉的主控单元发送提示和确认信息至语音处理单元1,由语音处理单元1播报语音信息“是否确定加热3分钟?”,如果是采用语音确认的设计,采集到用户说出语音命令“是”,语音处理单元1将该确定信息发送至微波炉的主控单元,如果是采用按键确认的设计,微波炉的主控单元需要采集按键的信号,总之在用户确认后,微波炉的主控单元再控制加热装置执行加热3分钟的动作。
当用户想知道微波炉的某个功能的操作方法时,可以先唤醒微波炉,然后说出命令词“智能烹调功能怎么使用?”,语音处理单元1识别到此命令词后,发送给微波炉的主控单元,微波炉的主控单元会发送相应的播报命令到语音处理单元1,语音处理单元1通过扬声器直接播报具体的操作方法给用户听,使其轻松知晓微波炉的操作方法。
综上所述,本实用新型使家电本体上无需再设置用以启动语音识别工作的触发装置,语音识别创新性地通过某个特定的语音唤醒命令来启动,可以帮用户全面实现对家电进行快捷、人性化的交互式操控。
