Accurate human voice reproduction


In your opinion, which speakers reproduce the spoken human voice the best?

I have noticed surprisingly that on some speakers which are great at reproducing singing, speech can sound off.

Can you give us an example of a speaker and situation where a speaker can sound good with singing but not with speech that is not recording-dependent?
I think Kr4 makes a good point. The production of a spoken voice recording may be completely different than for singing. Singing is done (hopefully), for good sound, and spoken voice for communication. Going on that assumption, its only natural that there's a gap in sound quality.
