摘要: 目前语音空调产品大都共用同一个唤醒词唤醒设备,因此,当多台语音空调被同时唤醒时,会产生“一呼百应”的现象,为解决这一现象,提出就近语音唤醒关键技术研究及空调应用。通过前端语音自适应降噪算法解决室内环境噪声以及空调内部混响,其次通过局域网语音就近唤醒组网选举得到master节点(主节点)和slave节点(子节点),最后根据声源发出声音的能量值或声源离语音空调距离值大小,经过master进行仲裁决策,最终让靠近用户最合适距离的空调被唤醒。

Abstract: At present, most voice air-conditioning products share the same wake-up word wake-up device. Therefore, when multiple voice air-conditioners are wake-up at the same time, there will be a "echo" phenomenon. In order to solve this phenomenon, proposes the key technology research and air-conditioning application of nearby voice wake-up. The front-end voice adaptive noise reduction algorithm is used to solve the indoor environment noise and the internal reverberation of the air conditioner. Then, the master node (master node) and slave node (sub node) are selected by LAN voice distributed networking. Finally, according to the energy value of the sound source or the distance between the sound source and the voice air conditioner, the arbitration decision is made by the master, finally, the air conditioner close to the user's most suitable distance is awakened.

Key words: Nearby voice wake up, Adaptive noise reduction, Distributed networking, Arbitration decision, Air conditioning application
