Abstract (in Japanese) (See Japanese page) 
(in English) We propose a browser-based speech recognition system using HTML5 in a broad sense and report its performance in actual use. Our proposed method enables browsers in PCs and mobile devices to use speech recognition function by client-side JavaScript code. Unlike traditional Web applications, there is no need to install specific application or browser plug-in. The flow of processing, at first getting the streaming audio data from the microphone of the client, and the client device transmits its streaming data to the speech-recognition server by the WebSocket protocol. In consideration of the quality of mobile broadband, by using client-side JavaScript, compres- sion for audio data is also performed, and the Voice Activity Detector(VAD) and the speech recognition decoder are implemented to the server because of the reduction of the computational cost of the client. In this paper, we explain the architecture of our proposed system and support status of browsers and devices. And we also report the audio compression performance in the client and the quality of actual use in mobile broadband. In the result, the proposed method has adequate quality as using speech recognition system.
