intonation question
 

hi all, i was wondering when you say desu ka the intonation is rising at ka right?

what if i say deshita ka is the intonation still rising?

Rising intonation at the end of a sentence is generally a question in Japanese. For example if you were asking someones name in this way:

なまえは
namae wa

The intonation would still rise at the end.

Someone correct me if I'm wrong but this is what I have observed.

un, I agree^__^
I think the same as SceptileMaster.
As much as I know it's right..xD

I don't intonate Japanese questions the same way I do in English, if that's what you're asking.

actually i meant like when a sentence is turned from present tense to past tense. something like this:

1. nihongo o benkyo shimasu ka?
(this is rising intonation)

2. nihongo o benkyo shimashita ka?
(what intonation would this sentence be at the end, is this still rising cause it sounds a bit weird)

It doesn't sound strange because only the final syllable needs to rise in pitch. If it's a question normally it rises in pitch at the last syllable.

Raising the intonation of the ka sounds weird. In fact, I`d say that you lower it instead of raising it. Question intonation is not the same in Japanese and English.

yeah... nan-desu ka ;-)

This. You seem to be applying English interrogative rules to Japanese. This is patently not correct. I kept trying to think of questions where I'd raise my voice like in English questions, but I couldn't find anything that sounded natural to my ears. The existence of the か there means you do not need to raise the intonation at the end of a question.
