Alexa is a virtual assistant created by Amazon which runs on the Amazon Echo devices.
Users interact with Alexa by voice command to initiate many actions such as; set alarms, play music, podcasts, or audiobooks, create to-do lists, and inquire about the weather, traffic, news, and other information.
Until now, Alexa’s voice has been a spoken female voice, but Amazon has just added the ability for Alexa to whisper. Alexa will also be able to take a breath to pause for emphasis and adjust her rate, pitch and volume.
