At present, digital home assistants such as Alexa, Siri, and Google answer queries to its users. However, for any follow-up question, the conventional phrases, such as 'Hey Siri' or 'OK Google' have to be repeated each time.
However, with the new opt-in feature, Alexa will listen for five seconds after the first response. If the device is ready for a follow-up question, the blue indicator light will flash, thereby indicating to the user that he/she can ask the next question. If no follow-up question is being asked, the device will restore to the sleep mode.
The new feature, Amazon said, will be available on all hands-free Alexa-enabled devices.
