Home Voice Assistants (HVAs) like the Amazon Echo or the Google Home are increasingly being used to control smart devices in a smarthome. A HVA device takes in a spoken command (“Turn off the living-room lights and television”), and converts it into commands for respective devices. This paper presents CANVAS system, an Context AwareNess for Voice ASsistants system designed for multi-occupant smarthomes. CANVAS is designed to be run on a HVA, and makes use of the sounds in the home to provide additional context information to decide whether to execute the command, prompt for confirmation, or reject the command entirely. CANVAS also includes a pictorial utility to help non-expert users configure these rules. Our experiments indicate that CANVAS has a low computational overhead, making it suitable to be executed in HVAs. Our experiments Mechanical Turk suggest that the pictorial configuration utility is also intuitive.

诸如Amazon Echo或Google Home之类的家庭语音助手（HVA）越来越多地用于控制智能家居中的智能设备。HVA设备接受语音命令（“关闭客厅的灯光和电视”），并将其转换为相应设备的命令。本文呈现帆布系统，Ç ontext甲洁具Ñ ESS为V音色AS专为多人智能家居设计的sistants系统。CANVAS设计为在HVA上运行，并利用家庭中的声音来提供其他上下文信息，以决定是执行命令，提示进行确认还是完全拒绝命令。CANVAS还包括一个图形实用程序，以帮助非专业用户配置这些规则。我们的实验表明，CANVAS具有较低的计算开销，使其适合在HVA中执行。我们的实验Mechanical Turk建议图形配置实用程序也很直观。
