Alexa can also control several smart devices using itself as a home automation system.

Today, interaction and communication with Alexa are only available in English and German. Last November 2017, Alexa became available in Canada but it offers English only. As of September 2017, Amazon had more than 5,000 employees working on Alexa and related products.

These skills are third-party developed voice experiences that add to the capabilities of any Alexa-enabled device. These skills are available for free download using the Alexa app. Skills are continuously being added to increase the capabilities available to the user. All of the code runs in the cloud – nothing is on any user’s device. A developer can follow tutorials to learn how to quickly build voice experiences for their new and existing applications. Amazon allows device manufacturers to integrate Alexa voice capabilities into their own connected products when using Alexa Voice Service. Products built using AVS have access to Alexa’s growing list of capabilities including all of the Alexa Skills.

The device is technically capable of streaming voice recordings at all times, and in fact, will always be listening to detect if a user has uttered the wake word. Amazon uses past voice recordings sent to the cloud service to improve response to future questions the user may pose. To address privacy concerns, the user can delete voice recordings that are currently associated with the user’s account, but doing so may degrade the user’s experience using search functions. To delete these recordings, the user can visit the Manage My Device page on or contact Amazon customer service.
