How to Change Wake Word
You can also change wake word from the Alexa app:
Tap Settings, and under the General section, scroll down and select “Wake Word“. Select your preferred wake word and tap OK.
How to Change Voice
Just like with changing the wake word, you can also use voice control to change Alexa’s voice on your Echo Dot and Echo Show device. All you need to say is “Alexa (or whatever wake word you’ve changed it to), change your voice.” You will immediately get a response with a masculine voice, and vice versa. Here’s how to change it on the Alexa app:
Tap the Settings icon at the top-right corner, and under the General section, scroll down and select “Alexa Voice“. Select New to enable the masculine-sounding voice.
