multiple language issues

Hello

the default language on my site is English, but i have some people posting dutch comments while on the english translated page.
how can i make it that these comments are translated into english automatically.

these comments will translate into other languages , such as spanish and french, when i click on a different language flags for my page , but when i click on the USA flag for English the comments return to Dutch.

I hope this makes sense . Any help is welcome

thank you
