GCompris, need some help before including syllable activity

One of my colleague (I work in a primary school) asked if we can not add a syllable activity in GCompris.
We can do it technically, using an existing activity called click_on_letter.
What we are not really sure about is, how general can be this activity.
I know that it works well in English, French, German, Spanish.
For example in french I can record an ogg file called ta.ogg and present several syllables “TA,TI,TO,TU” and ask the user to find the right one.
Our problem is, how internationalisable this activity is?
Would it be possible to translate it to Chinese for example?
Does Chinese uses syllables?
Here are the languages we cover.

Thanks in advance for your help.
