The firm demonstrated a piece of software called Talkman, which utilises the built-in microphone port of the PSP and allows users to speak into the device in one language and have what they said translated into another, spoken, language. The software uses a cartoon bird as its main interface, which is able to converse in, and translate between, up to nine languages.

The demonstration at the conference only showed Talkman translating between Japanese and English, but the company suggested that in its final incarnation, the software will be extremely useful as both a foreign language training tool, and as a translation device for people abroad.

It' s not clear whether it would be possible to use Talkman to translate real-time voice conversations between PSP users - a feature which was recently revealed for mobile phones by Toshiba.
