TechCrunch says whisper mode is rolling out to Echo customers in the United States starting today. When the feature is rolled out to you, it can be enabled using voice or the Alexa app:

  • Whisper is an account setting, so it needs to be turned on in the Alexa App under Settings →  Alexa Account →  Alexa Voice Responses →  Whispered Responses.
  • Whisper Mode can also be enabled by voice, simply by saying “Alexa, turn on whisper mode.”

If Alexa whisper mode works as advertised, hopefully it will inspire Siri to learn a similar trick. Like Echo smart speakers, Apple’s HomePod faces a similar challenge of unnaturally loud responses in quiet situations if the speaker volume is cranked up too loud.

I think whispering can be noisier in some cases. Sort of a raspy smoker’s voice. pic.twitter.com/krrJTGCn74
