多关键词离线语音唤醒模块的实现

The Realization of Multi-keyword Off-line Voice Wake-up Module

语音识别技术越来越多地被应用在工业、家电、通信、医疗、汽车电子等领域,其中关键词识别是识别已知的简短词语.为了减少在线语音监听设备资源损耗,搭建了多关键词离线语音唤醒模块,基于Snowboy语音检测引擎,以Raspberry Pi 3B+为核心控制器,采用Python开发环境,实现离线语音热词的检测,支持多关键词唤醒.有效减少资源损耗,同时保护数据安全.适合各种语音识别、语音唤醒、语音控制等嵌入式系统.

Speech recognition technology is more and more used in the fields of industry,home appliances,communication,medical treatment,automotive electronics,etc.,in which keyword recognition is to recognize known short words.In order to reduce the resource loss of online voice monitoring equipment,a multi-keyword offline voice wake-up module is built.Based on Snowboy voice detection engine,Raspberry Pi 3B+as the core controller,and Python development environment is used to realize the detection of offline voice hot words,supporting multi-keyword wake-up.Effectively reduce resource loss and protect data security at the same time.It is suitable for various embedded systems such as speech recognition,speech wake-up,speech control,etc.
