"Hello - Is Anybody at Home?" - About the Minimum Word Accuracy of a Smart Home Spoken Dialogue System

Jan Felix Krebber

Ruhr-University Bochum, Germany

This paper presents the assessment of the minimum word accuracy of an automatic speech recognizer within a spoken dialogue system, which is required to reach acceptable quality. The spoken dialogue system has been developed in the context of the European INSPIRE project [3]. It is used to control a smart home environment. The assessment of the minimum word accuracy is done within the assessment of all modules of the INSPIRE system. The outcome of this assessment will act as a benchmark for the developers of other modules, mainly of the speech preprocessing (microphone array with beam forming and denoising) and for the engineers and phoneticians tuning the automatic speech recognizer. The article describes the test and the outcome of the estimation of the minimum word accuracy necessary to use INSPIRE in an acceptable way.
