The basic idea is simple, and a little bit obvious in hindsight.
"The blue indicator light on the Echo device remains on for a few seconds, letting you know that Alexa is active and ready for your next request", Amazon explained in a support note. This follows a problem last week where Amazon Alexa stopped working altogether and wouldn't respond to voice commands at all and essentially lost her voice.
Amazon's digital assistant, Alexa, who, thanks to her artificial intelligence, answers questions and receives orders from users, shows odd symptoms - which refer to parapsychological thrillers - as she suddenly starts without a reason to laugh in a frightening way it can freeze the blood.
To be clear, this doesn't mean that Alexa can handle multiple commands at once. At the very least it'll cut down the amount of times you have to say "Alexa" in any given day. Just head to the Settings page of the app, select the device you want to configure, find Follow-Up Mode and tap the toggle to switch it on.
They added: "In rare circumstances, Alexa can mistakenly hear the phrase 'Alexa, laugh.' We are changing that phrase to be 'Alexa, can you laugh?' which is less likely to have false positives, and we are disabling the short utterance 'Alexa, laugh'".
Amazon says Alexa will only respond to a follow-up commands if she's "confident" that it is a legitimate request and not just background noise. If no follow-up question is being asked, the device will restore to the sleep mode. If you need a lot doing, you can end up saying "Alexa" so many times that it starts to sound like a fake word or that you're going slightly mad talking to someone who isn't actually real.
