KDDI corp., a cell phone network operator in Japan, has been working for the
communication services under mobile environment. KDDI is also working for the
development for the future telematics services over cell phone network. KDDI is now
developing a common platform for car drivers and cell phone users to provide mobile
information services based on speech recognition technology, as we believe the
user-friendly HMI is a key element for the growth of mobile services including motor
vehicles.
One of our current efforts to provide such services, is the development of the voice
service platform based on distributed speech recognition (DSR), as this technology
provides the following merits compared to the conventional speech recognition over cell
phone network:
-
Resilience to intermittent errors due to mobile circumstances
-
Multi-modal access using both voice and data
-
Lower bandwidth
To explore and evaluate the possibilities of DSR, we are conducting on the experiment
using IP technologies such as XML and Web browser based multi-model DSR client and
DSR recognition server.
We present the development of DSR evaluation system and discuss the following:
1)
Voice service architecture for multi-modal applications
2)
Development of voice service platform based on DSR
3)
Evaluation of DSR-based system
4)
The area of standardization
