Well, sometimes, it does. You know when someone is insulting you and you say something like "Enough!" or two people are fighting and you say just the same thing or any other case like that? Well, in these cases, in Portuguese, you'd say "Chega!" (or "Já chega!" "Basta!" or something like that).
As a matter of Interest, text-to-speech could not recognize the speakers words no matter how many tries. If I try to emulate this I get the same result. The male native speaker needs to speak a little slower so that all learners can pick up the nuances of pronunciation. If Google can't recognize it as any Brazilian Portuguese phrase, then there definitely is an issue.
