The McGurk effect is a well-known experiment in which, while hearing a given phoneme and seeing someone pronouncing another phoneme, we “hear” the second one instead of the first one, the correct one. This seems to mean that the auditory perception of a phoneme is already processed, it is savikalpa. Try the McGurk effect in the following video:
Now, the problem is that, after many trials, this does not work with me. I guess that this might have to do with the fact that I am not an English Native speaker and that, accordingly, I process the image of someone pronouncing the second phoneme in a non-automatic way (after all, /f/ as pronounced in my native language is probably not pronounced with the same lip movement).
What do you think, does it work with you? If yes or if no, what is your native language
