If you hate the way your voice sounds over recordings, you're not going to like hearing Google has been recording your terrible voice this whole time. Also, you officially have no privacy.
As revealed by The Independent, if you use voice command Google products, like "OK, Google," well, Google has a record of everything you've ever said while using such products. It's all in your Google History and has been in there since June 2015 when Google started keeping track of this activity on its Voice and Audio page.
On that page, you should be able to see your entire voice history, how each item was recorded, and tearfully listen to your voice. You may also see transcriptions if Google was able to translate the voice recording into text. Fortunately, from this page, you can also delete everything.
Here's how you do the deleting: Go to the right hand corner and click on the indicated dots.
