Does anyone know of and TTS available now that doesn't completely muck up foreign words? I know you can make custom pronouncing dictionaries to use with some of the open source ones, but I wonder if any of the more modern systems are good for this. I have been listening to the english news podcast from a japanese news paper that is made with TTS and it gets its one job, pronouncing Japanese names and places completely jarringly wrong.
