Not an onomatopoeia

My Spin Instructor, John, is making us all crazy by insisting that there is a word that means, “sounding out the word” such as, “fast and LOW” saying the word low in a deeper voice. I don't believe there is such a word but need some back up.

It's time to spin your spin instructor! If he's the one insisting that there is a word for it, the burden of proof is on him! In such situations I challenge the person to a bet, for some small amount like ten dollars, or lunch or dinner. If he's so unsure that he's not willing to put his money where his mouth is, then he loses the right to "insist." And, if he is right and there is a word for it, the ten dollars you lose is well spent because you learn something, making it a win-win in my book!
Of course, now that you've posted the question here, Grant or Martha will surely know the answer.
I always thought that when people speak in dramatic fashion, "sounding out the words," it is called opera. π
Thanks, I will do just that!
Margaret, I can't think of a word like that offhand, although of course it may exist. I suppose there's a chance it might be some obscure term of rhetoric. But I agree with samaphore.
Is your instructor insisting on this while all of you are spinning? It's a great mental picture, in any case!
