5 5 Toshiba Speech and Language R&D Toshiba China R&D, Beijing Toshiba Corporate R&D Center, Kawasaki Toshiba Research Europe Ltd, Cambridge

6 6 CRL Speech Technology Group Toshiba China R&D, Beijing Toshiba Corporate R&D Center, Kawasaki Focus on embedded ASR and TTS –Core technology research and development Noise and speaker robustness LVCSR HMM-TTS –European and North American languages Approx 15 researchers –Multinational team –Mix of engineers, computer scientists and linguists

7 7 Vision of Toshiba Speech Research Enhance the human-machine interface  Interact with devices how, when and where you want Create a paradigm shift  Input/output  communication

8 8 Speech Recognition Challenges Speaker Robustness Noise Robustness Task Robustness Current ASR engines still suffer from lack of robustness –Major limitation in deploying speech recognition systems

9 9 Text-to-Speech Synthesis Challenges Increase in naturalness of synthesis –Same or even smaller footprint! Increase in voice variety –Faster, cheaper addition –Non-professional voices neutral friendly expressive emotional large corpus professional voice small corpus professional voice small corpus amateur voices
