Echo is a series of smart voice assistant devices by Amazon. You can review and listen to voice commands given to Alexa on your Amazon Echo, inside the Alexa app, and any other device with Alexa built in. From here, you can delete the voice recordings individually or in bulk. The settings also allow you to stop saving your Echo recordings. Finally, you can even ask Amazon to no longer use your Alexa voice recordings for evaluation and training purposes. This'll ensure no human hired by Amazon listens to them. In this guide, we show you how to do all these using the Alexa app on your iPhone, iPad, Android, and the Amazon website in a browser on Mac or PC.
