论文摘要
唤醒是语音互动中的主要功能，这是智能家居的人机交互（HMI）应用程序中的主流方案。如果所有设备都使用相同的唤醒单词，则所有设备都将响应。这将带来混乱并降低体验用户质量（QOE）。解决此问题的唯一方法是使基于同一评分规则的同一无线局域网（WLAN）中的所有设备与唤醒竞争。将选择最接近用户的一个进行响应。为此，在本文中提出了一种竞争性的唤醒方案，该论文采用精心设计的校准方法来接收麦克风的能量。此外，用户方向有助于确定最佳设备。实验揭示了该方案的可行性和有效性。
Wakeup is the primary function in voice interaction which is the mainstream scheme in man-machine interaction (HMI) applications for smart home. All devices will response if the same wake-up word is used for all devices. This will bring chaos and reduce user quality of experience (QoE). The only way to solve this problem is to make all the devices in the same wireless local area network (WLAN) competing to wake-up based on the same scoring rule. The one closest to the user would be selected for response. To this end, a competitive wakeup scheme is proposed in this paper with elaborately designed calibration method for receiving energy of microphones. Moreover, the user orientation is assisted to determine the optimal device. Experiments reveal the feasibility and validity of this scheme.
