How to say it
The tag line for the web site Forvo.com is "All the words in the world. Pronounced." Using the power of people who want to contribute, they are creating a catalog of audio recordings of how words are spoken. You can contribute too, if you like. Behold yet another awesome tool provided by the intertubes. The site could use some better bablefish type cross-referencing. Even without that, a creative person could probably assemble a pretty good foreign language course using this as a back bone. Sentence construction would be tough, but for the simple individual word standpoint, there's some nice potential. Now that I think about it, the potential of the internet to provide foreign language education is HUGE. A quick search makes it look like at least one site is working on this: phrasebase.com. Using a Wikipedia approach to foreign language teaching/learning should be well within the realm of possibility.
