Tipa2Unicode is a little stand-alone application which let's you input Tipa-shortcuts and then displays Unicode symbols. You can then paste either side of the conversion to LaTeX or a word processor.
Until this whole project is set up, here is some background information about the problems, the tools and of course, the solution.
The Sourceforge Project Site of Tipa2Unicode. There you can download a first version of the tool.In order to display the phonetic symbols, you need a Unicode font on your computer. Why not try the Doulos SIL which you can download from the SIL pages.
The Tipa Manual (PDF). Tipa is a package for LaTex. It uses shortcuts to input the phonetic symbols.
