Talkman is a Microphone for PSP accompanied with voice recognition software, allowing you to speak japanese in theory.
The software can be used to translate English to Japanese, Korean, and Chinese to name a few, and vice-versa. The retail price will cost £10 more than a regular PSP game, and is due for launch in Japan this November.
The Talkman will be available in Japan for approx $50. UK price will probably be in the region of £40 – £50. A UK launch date has not been confirmed.
