| Outline of Final Research Achievements |
In this study, a new and novel speech recognition system has been developed. It is suitable for noisy circumstances and sustainability environment. The developed system has been evaluated under several real noisy circumstances and thus it is realized into an autonomous robot for actual application. In the first step, a new automatic speech recognition system with high performance noise robust has been designed and developed. The expected noise SNR is lower than 10 dB. In order to apply this system into severe noise conditions, noise reduction over the running spectrum domain and psychoacoustic processing have been introduced. At the same time, the system is also considered to be suitable for the sustainability environment. In order words, the low power consumption system design, i.e., the software and hardware co-design method, has been applied to the proposed system and it may be useful for the system with energy harvesting mechanism.
