Oh, no, there isn't any problem. In order to comply with the Americans with Disabilities Act, they let a couple of wheelchair-bound Trekkies write this episode.
As it turned out, those geeks got really stoned when they wrote it, and they thought it would be hilarious if Leonard Nimoy spoke in the deepest voice he could manage.
Ah, so the sound that I'm hearing is only the sound of the low Spock of high wheeled boys?
