The exact origin of this clip is not clearly documented, so it is best understood as a piece of Brazilian internet humour that circulates through soundboards and short-form edits rather than a line from a widely known film or series. Its title plays on everyday Portuguese words for throat and voice, which helps it travel among Portuguese-speaking creators who recognise the joke at once. It has remained in use because the premise is instantly reusable: a tired voice, a sudden attempt at polish, and a listener who knows exactly what that sounds like.
