This touching video shows a woman's reaction to her cochlear implants. It seems to me amazing that someone hearing for the first time would be able to understand the signal (speech) so well and even apparently know that the sound is too high-pitched. I imagine that the technician is probably signing quite a bit, but nonetheless, it seems like the patient is understanding spoken speech at least to a significant degree.
Do people who have never experienced sound immediately have the ability to interpret spoken language? (I've seen another video where a person with cochlear implants is moved by her first exposure to music, which raises similar questions.)
(Not sure if this is more a straight biology / medicine SE question...)
