Network and Embedded Applications of Automatic Speech Recognition

ASR (Automatic Speech Recognition) is one of key technologies in the upcoming Ubiquitous Computing and Ambient Intelligence. In this paper, first, the surveys on processing devices such as microprocessors and memories, and on communication infrastructure, especially wireless communication infrastructure re-lating to ASR are reported. Second, the embed-ded version of CSR (Continuous Speech Recognition) software for the mobile environmental use of ASR is reported. As the devices, RISC based microprocessors, semi-conductor memories, and HDD are summarized. For the communication infrastructure, mobile communi-cations and wireless LANs are described. Finally, im-plementation results of the free CSR software called Julius on the T-engineTM consisting of an SH-4A mi-croprocessor are reported
