No, they certainly won't.
That's the problem with a tonal language. If you don't use the right tone for a word (and there are five different (possible) tones for each word in Thai, whether the tone has an actual meaning or not), the word you're using (or think you're using, ) will have a total different meaning from the one you intended to, OR no meaning at all cause the specific tone you used for this word has no existing meaning.
I've had three consecutive years of Thai language classes in a proper school here in Phuket. (for the context of what I'm saying).
