EXPECTATIONS FOR VOICE INTERFACE Many of us have now experienced conversation with computers by voice. When I first experienced it more than a quarter-century ago I was a little shocked, even though it was just a simple conversation.

VOICE INTERFACE IN THE C&C INFORMATION SOCIETY There are many applications for new C&C technologies. In the area of public information services there are applications in employment, securities, risk management, taxation, health, education, marriage, entertainment, shopping, and even funeral arrangements.

In 1959 we developed a spoken digit recognizes. I believed that word recognition for a small vocabulary was within reach, and we challenged ourselves to produce a voice dialing mobile telephone system.

However, most of them needed more than a simple word recognizes, and this forced me to begin research into continuous speech recognition. Today, no one thinks about centralized machines because it is easy to install a voice dialing function inside the telephone.

To promote sales of the system, I also visited many end users, including an airline company in the United States. The Federal Aviation Administration was one of our earliest customers for speech recognition products and tested our technology for applications in flight control training in 1979.

Roughly speaking, our speech recognition processor, which was used at the TELECOM'91 demonstration, performed 1000-word continuous speech recognition at 1 GIPS processing with 100 Megabits of memory. If we apply the previous estimate for VLSI technological advances to speech recognition processing, we will see 10,000-word continuous speech recognition with 100 GIPS CPUs and 1 Gbit memories in the 2000s, even if we assume a 10 to 1 increase in hardware for vocabulary improvement.

Roughly speaking, this corresponds to 1/250 of CPU chip space in today's technology and only 50k primitive instructions per second. FUTURE RESEARCH AND DEVELOPMENT ISSUES Progress in VLSI technology is going to enable us to do an enormous amount of speech processing in a chip, and as a result the contents of the methods for speech processing become more important.

The second issue for future R&D is the smart interface. Areas of importance for the smart interface include speech-to-text conversion, or dictation, and a conversational spoken language interface.

I am glad, as a proposer and supporter, that automatic interpretation research is now receiving worldwide attention including work in the United States, Germany, and Japan. In 1991 NEC demonstrated its improved automatic interpretation system, INTERTALKER, at TELECOM'91 in Geneva.

From page 514... ...
Automatic interpretation will help us realize the dream of human global communication that bridges the language gap. It is also an important goal for voice technology.
