Construction of a recognizer in a new target language usually involves collection of a comprehensive database in that language as well as manual annotation and model training. For rapid development of new language recognizer, we propose 1 substituting target language phoneme models by source language phoneme models trained previously; and 2 adapting target(More)
In this paper, we present a prototype speech-based Web browser, SALSA1.0, and describe some of the research issues we need to address while building this system for Hong Kong users. SALSA1.0 allows the user to speak English command words as well as partial or complete link names on any page. The research issues involved in building SALSA1.0 are mainly (1)(More)
We demonstrate the temporal and spectral evolution of picosecond soliton in the slow light silicon photonic crystal waveguides (PhCWs) by sum frequency generation cross-correlation frequency resolved optical grating (SFG-XFROG) and nonlinear Schrödinger equation (NLSE) modeling. The reference pulses for the SFG-XFROG measurements are unambiguously(More)
