Answer 1

This is a great question, Google does provide a way of doing that through the Web Speech API. Here's a link to an example usage, and a demo site from Google here.

However, you would have to extract the audio from the video first and then feed the audio to the API.

There's also the Cloud Speech API, which is free up to a certain point. It can be found here.
