Devloper need urgent

ONLY BID IF YOU 100% CONFIDENT FOR THIS PROJECT READ CARUFULLY !!! NEED IN 1 DAY MAX !!! This is to implement the github project at [login to view URL] (or write your own code if you prefer) into the chat application i have made ([login to view URL]). For now we can just test it with 2 languages, say English and Mandarin (both supported by Google web speech API which this project uses). If the user selects "A" in the first box and "B" in the second box and they begin voice chat, the application will listen for english and translate it into Mandarin, writing the text for both languages (as in [login to view URL] except without the computer voice reading out the translation). The user will need to have the option to toggle between viewing the voice to text translations AND the normal chat text, or just the normal chat text without the voice to text translations. In terms of UI the button for that can just be in the top right next to the Voice Chat button. I will provide my good translate Api key !!! i need to be done today !!! only expert person !!!
