Although the McGurk effect's importance may seem isolated to just psychological researchers and scientists, this phenomenon has been expanded to everyday audio and visual speech perception as well. Two researchers by the name of Wareham and Wright conducted a study in 2005 that may suggest that the McGurk effect can influence how everyday speech is perceived. This is especially important in witness testimony where the observations and accounts of the witness are usually expected to be accurate and correct. With this information, witness testimonies now must be interpreted with the notion that the witness may be unaware of their own inaccurate perception.
