If you want Amazon's Alexa digital assistant to do something for you all you need to do is say "Hey, Alexa" and it will wake up and start listening for a command. The follow-up mode won't work, however, if Alexa isn't "confident you're speaking to her", according to Amazon. The blue ring on your Alexa device of choice will light up during these five seconds to indicate that she's listening. As usual, saying "stop", "cancel" or "go to sleep" will stop Alexa from listening. This means that the user will have to clearly issue the command because if they don't, Alexa probably won't separate it from the background noise.
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'". You'll know if Alexa is ready for a follow-up question if the blue indicator light is on after Alexa answers your first question. ALEXA: "OK, the heat is set to 68".
The have been widespread reports that Amazon Alexa has been freaking users out by giving a creepy laugh at unexpected moments and even reading out the names of funeral homes.
The feature is available on all hands-free Alexa-enabled devices, like the Echo, Echo Dot and Echo Spot. Select the device in question, then scroll down and toggle the Follow-up Mode slider into the on position (it's off by default). If you say nothing, it will soon go off to show she's stopped listening.
Only available in US English and on Amazon Echo devices for now, Follow-Up Mode can be switched on via the Alexa smartphone app.
