[(l)isten/(p)ause/(q)uit]: 

• Fix bugs in the chess moves logic
• Improve web-browser audio capture - sometimes it does not record the voice properly
• Add support for more languages by making the generated grammar string multilingual
• Explore ways to improve the dynamic grammar to be narrower

PRs welcome!
