Voice-enabled speaker usage to grow nearly 130% this year. With 30–38% of Echo Dots’ spurious audio recordings were human conversations, these findings support the Echo Dot recorded private home conversations and not all audio recordings are properly logged the Alexa Application. Then, by comparing that AVS signature and logged Alexa audio commands to the 21-day network traffic dataset, this study confirmed disabling the Echo’s microphone, with the on/off button, prohibits audio recording and streaming to Alexa Voice Service. Using a k-mean cluster analysis, this study established a quantifiable AVS network signature. All recorded audio commands were inadvertent. ![]() The Echo Dots were installed in a private residence, and at no time during the experiment did family members or house guests purposely interact with the Echos. This paper contributes to the intelligent personal assistant knowledge domain by providing insight into Amazon Voice Services behavior by analyzing the network traffic of two Echo Dots over a 21-day period. As corporations integrate Alexa into their corporate networks, it is important that information technology security stakeholders understand Alexa’s audio streaming network behavior in order to properly implement security countermeasures and policies. In November 2017, Amazon expanded Alexa services into the business intelligent assistant market with Alexa for Business. Amazon’s Alexa Voice Service (AVS) provides voice control services for Amazon’s Echo product line and various home automation devices such as thermostats and security cameras.
