Short bio

Piergiorgio Svaizer received his degree in Electronic Engineering from the University of Padova in 1989. In 1991 he joined ITC-IRST (now FBK-IRST) where he has been working in the Speech Recognition Group and then in the SHINE research unit. His current research interests include digital signal processing, microphone arrays, automatic speech recognition in noisy and reverberant environments.

    Use of parallel recognizers for robust in-car speech interaction,
    This paper refers to an activity under way at the speech recognition technology level for the development of a hands-free dialogue interaction system in the car environment. The use of a set of HMM recognizers, running in parallel, is being investigated in order to ensure low complexity, modularity, fast response, and to allow a real-time reconfiguration of the language models and grammars according to the policy indicated by natural language understanding and dialogue manager modules. A corpus of spontaneous speech interactions was collected using the Wizard-of-Oz method in a real driving situation with a microphone placed far from the driver. The use of parallel recognition units, each specialized on a given geographical domain, was explored using the resulting real corpus. Experiments show the advantage of selecting the recognized sentence according to the maximum likelihood among the active units when compared to the use of a single language model based on a very large vocabulary.,
