Quality assessment for speech recognition systems is a complex problem involving many factors but it all starts and ends with a proper synthesis of user scenarios in a controlled acoustic environment. In this paper industry leading background noise reproduction methods are presented. Implementations of two ETSI standards for noise reproduction, the ES 202 396-1 and TS 103 224 are measured and compared to determine the vulnerability for sound pressure level and frequency response deviation around the setup center.
