A single word for "liking someone's speech/quote/idea"?

I usally hear the word compounds "well-said, well-spoken etc.." to express the appreciation of someone's speech or a useful idea, but I never heard such a single word to express that.

PS : I'm not searching for answers like : "To agree etc..." or general terms of "admitting/accepting things".

EDIT : I've found a useful interjection "Touche", but still wondering if it can be used in business speech.
