Speech Synthesis Middleware: ToSpeak™

ToSpeak™ is Text-To-Speech software IP that enables smooth and natural reading of text data while running on the CPU and memory of a local device.

Features

Smooth Reading
  • Using Toshiba's proprietary technology, ToSpeak™ delivers smooth and natural speech with uniformly high sound quality.
Clear and Natural Sound Quality even with Small Memory Footprint
  • Clear sound quality is kept enough even with only a few megabytes of memory for the synthesis unit dictionary (voice database).
Small Computational Cost
  • With its compact size, ToSpeak™ can work in real-time even when run on local terminals. In this case it eliminates the problem of network delay, which is unavoidable with cloud solutions.
