Creating Multiple Language Presentation with Latex Beamer

Question

I love creating presentation with latex beamer. The result is awesome. The problem is, I'd like to provide my presentation in english and in another language.

What are the tips and trick to do this? Should I manually comment the english string, translate it and compile it to have result in another language? Are there any better mechanism?

What I meant by tips and tricks are the fast and practical way to do it.

Answer 1

The following should do the trick:

Create a new package languagechooser.sty with the content:

\newcommand{\english}[1]{}
\newcommand{\german}[1]{}

\DeclareOption{english}{\renewcommand{\english}[1]{#1}}
\DeclareOption{german}{\renewcommand{\german}[1]{#1}}
\ProcessOptions

Now create your beamer presentation with the content provided for your favorite languages like this

\documentclass{beamer}
\usepackage[german]{languagechooser}

\begin{document}

\begin{frame}{\english{English title}\german{Deutscher Titel}}
\english{This ist some english content.}
\german{Dies ist ein deutscher Inhalt.}

\begin{description}
\item[\german{Hallo}\english{hello}] \german{Welt}\english{world}.
\end{description}
\end{frame}

\end{document}

By altering the option of your new package, TeX will consider only content in that language. However, it is a shame that you have to write everything twice (once for each language), but as long as there is no major improvement in automatic translations, I think this is unpreventable.
