Coventry South Labour MP Zarah Sultana claims Parliament must change to become more relevant.
She said language was very important to that and explained: "If we really want to relate to people and if we want to be accessible, then we need to be talking the way people talk.
Ms Sultana succeeded Jim Cunningham in December's general election.
She added: "There's a lot of people who feel like Parliament and politics is something beyond their reach. That it's something that they need to study a degree to understand. And that's absolutely not the case."
