Investigating the impact of lip visibility and talking style on speechreading performance

► We explore the impact of lip visibility and speaking style on speechreadability. ► We compare speechreading from talkers with natural, bright and concealed lips. ► Highlighting the lip area by lipstick or concealer improves speechreading. ► Speaking in a clear (rather than conversational) manner improves speechreading. ► Results are discussed in practical terms and in relation to attention and movement.
