NEC is behind this technology, which has actually been ported over from Papero, a robotic voice translating dog. The PDA is a little more portable though, making it a great fit for the mobile business traveler. In addition to being a translator, e-Navi serves as a mobile phone, airport information guide and offers unlimited web browsing. The hardware is manufactured by an Asian firm and runs Windows Mobile.
The quality of the voice is actually very good. It doesn t sound like the typical robotic monotone voice you might expect. For an English and Japanese voice sample, visit the e-Navi site: http://www.narita-airport.or.jp/e-navi/function.html
