KAWASAKI, Japan—Toshiba Digital Solutions Corporation’s ToSpeak™ RECAIUS speech synthesis middleware has been adopted for use in Sourcenext Corporation’s Pocketalk® W, an AI-powered voice translation device, as its new Japanese speech engine. Sourcenext will begin distributing the update starting today, December 27, 2018.

ToSpeak™ is a software library product for embedded devices that provides text to speech synthesis. It enables the synthesis of very natural sounding speech, instead of machine-like speech, which was the reason for the adoption of the middleware in Pocketalk® W.

Going forward, Toshiba Digital Solutions will continue to strengthen the function of the RECAIUS speech synthesis middleware, ToSpeak™ and support its application in various business circumstances.
