Creating an embedded audio chat unique to each query on API

This is a VERY difficult project and requires EXCELLENT English and understanding. There is a website called [login to view URL] & [login to view URL] which is for a video game called League of Legends. There is an official API released by the game to allow server queries and display information which is what [login to view URL] and [login to view URL] did. It allows you to realtime search your username when you are in game, and it gives information about your teammates and opponents. I want someone to help me with the design and implementation of embedding an audio chat into the page for EACH match (hundreds of simultaneous matches can exist) and also aside from audio chat for EACH unique match, also have two separate chats for EACH game because there are 2 different teams.
