Web Speech API for website with ads (commercial use)

I want to use Web Speech API and the code provided here (https://github.com/mdn/web-speech-api) in a website that i will put ads or it will support paid subscription (commercial use)

Am i allowed to use it commercially? I am not familiar with the licenses terms at all, but from my understanding, i am ok https://github.com/mdn/web-speech-api/blob/master/LICENSE
