Startup Idea: Volume Regulator and Voice-Controlled Text Editing Software

Startup idea to develop a software that can adjust the volume of loud commercials in free music streaming services on phones and smart TVs. Additionally, the software will allow users to rectify voice input errors on their smartphones by voicing deletion commands.

Loud commercials that come on free music streaming services on phones are annoying. Software that could regulate the volume increase (or even mute it completely) would be great.

The same could be done for smartTV's. When any noise gets too much louder than the rest at a certain volume, it could be regulated.

Also, when I speak into my smartphone and the phone types a mistake, I can't undo the mistake by voice.

It would be so helpful to delete the last word or certain number of words spoken. I would love to be able to say: delete last word, or delete last 6 words. I think that a secret code sound could be made, (that is not an English word) that could indicate that the phone should not type the delete commands.
