The hardware accelerator of the automatic speech recognition for the continuous Korean words

This paper describes the hardware of the speech recognition. The embedded speech recognizer should meet two conditions for the low-latency performance and the low-power dissipation. So, we made the fully-hardwired speech recognizer as the hardware accelerator to offload the system processor without the support of the remote computing environment. Our overall design was designed and implemented on FPGA board. Our design showed speedy response as the real time factor of 0.4 ~ 0.5 at 100MHz operating frequency and uses the HW resource of 10.
