Abstract
A testing arrangement provided for speech recognition systems in vehicles. Preferably included are a 'mobile client' secured in the vehicle and driven around at a desired speed, an audio system and speaker which plays back a set of prerecorded utterances stored digitally in a computer arrangement such that the speech of a human being is simulated, transmission of the speech signal to a server, followed by speech recognition and signal-to-noise ratio (SNR) computation. Here, the acceptability of the vehicular speech recognition system is preferably determined via comparison with pre-specified standards of recognition accuracy and SNR values.
