With this background, we examine the McGurk effect to assess its usefulness for furthering our understanding of audiovisual speech perception, joining the voices of other speech scientists who argue that it is time to move beyond McGurk ( Alsius et al., 2017 Getz and Toscano, 2021 Massaro, 2017). We start by reviewing behavioral findings regarding audiovisual speech perception and some theoretical constraints on our understanding of multisensory integration.

In this paper, we consider how to best investigate the benefits listeners receive from being able to see a speaker's face while listening to their speech during natural communication. At the same time, the stimuli typically used to elicit a McGurk effect differ substantially from what we usually encounter in conversation. 1 Since that time, McGurk stimuli have been used in countless studies of audiovisual integration in humans (not to mention the multitude of classroom demonstrations on multisensory processing) ( Marques et al., 2016). More than 45 years ago, McGurk and MacDonald (1976) published a remarkable (and now famous) example of visual influence on auditory speech perception: when an auditory stimulus (e.g., /ba/) was presented with the face of a talker articulating a different syllable (e.g., /ga/), listeners often experienced an illusory percept distinct from both sources (e.g., /da/). Speech perception in face-to-face conversations is a prime example of multisensory integration: listeners have access not only to a speaker's voice, but to visual cues from their face, gestures, and body posture. Although the McGurk effect is a fascinating illusion, truly understanding the combined use of auditory and visual information during speech perception requires tasks that more closely resemble everyday communication: namely, words, sentences, and narratives with congruent auditory and visual speech cues. Furthermore, recent data show that susceptibility to McGurk tasks does not correlate with performance during natural audiovisual speech perception. However, despite their popularity, we join the voices of others in the field to argue that McGurk tasks are ill-suited for studying real-life multisensory speech perception: McGurk stimuli are often based on isolated syllables (which are rare in conversations) and necessarily rely on audiovisual incongruence that does not occur naturally. Not all listeners show the same degree of susceptibility to the McGurk illusion, and these individual differences are frequently used as a measure of audiovisual integration ability. One approach to measuring multisensory integration is to use variants of the McGurk illusion, in which discrepant auditory and visual cues produce auditory percepts that differ from those based on unimodal input. Send us feedback about these examples.Although it is clear that sighted listeners use both auditory and visual cues during speech perception, the manner in which multisensory information is combined is a matter of debate.
