A New Hampshire judge ruled in November 2018 that authorities could examine recordings from an Amazon Echo device recovered from the home of murder victim Christine Sullivan for use as evidence against defendant Timothy Verrill. Investigators believe that the device, which belonged to the victim's boyfriend, could have captured audio of the murder and its aftermath.[82]
Alexa can perform a number of pre-set functions out-of-the-box such as set timers, share the current weather, create lists, access Wikipedia articles, and many more things.[24] Users say a designated "wake word" (the default is simply "Alexa") to alert an Alexa-enabled device of an ensuing function command. Alexa listens for the command and performs the appropriate function, or skill, to answer a question or command. Alexa's question answering ability is partly powered by the Wolfram Language.[25] When questions are asked, Alexa converts sound waves into text which allows it to gather information from various sources. Behind the scenes, the data gathered is then parsed by Wolfram's technology to generate suitable and accurate answers.[26] Alexa-supported devices can stream music from the owner's Amazon Music accounts and have built-in support for Pandora and Spotify accounts.[27] Alexa can play music from streaming services such as Apple Music and Google Play Music from a phone or tablet.
There are a number of ways messages can be sent from Alexa's application. Alexa can deliver messages to a recipient's Alexa application, as well as to all supported Echo devices associated with their Amazon account. Alexa can send typed messages only from Alexa's app. If one sends a message from an associated Echo device, it transmits as a voice message. Alexa cannot send attachments such as videos and photos.[49]
