The National Center on Accessible Educational Materials (AEM) also emphasizes that captions help everyone when:
- People are in noisy public environments such as airports, gyms, and restaurants.
- A person wants to watch TV while someone else is sleeping or studying in the room.
- A speaker in the video has a strong or difficult to understand accent.
- A video includes specialized or unfamiliar vocabulary (legal, medical or scientific terms).
- A sound system is not working, or the sound quality is poor.
Conversely, according to Automatic Sync Technologies (AST), poorly captioned and uncaptioned videos can negatively impact students who are relying on captions to access video content, including their educational outcomes.
