Coming soon to your Alexa device is an upgrade called “natural turn-taking”. The thought behind this upgrade is that you shouldn’t have to continually say “Alexa” to complete relatively simple tasks when they are only a few seconds apart.
Alexa’s AI will be able to recognize when users have finished speaking, when their speech is directed at the device, when it’s not, and whether or not a reply is expected.
On to privacy matters, you can now delete you can now delete every interaction you’ve had with Alexa with just one command. To do so, just say “Alexa, delete everything I’ve ever said.” This follows on from being able to delete everything you had just said that was introduced last year.
