摘要：- This paper addresses the impact of telephone transmission channels on automatic speech recognition performance. A real-time simulation model is described and implemented, which allows impairments that are encountered in traditional as well as modern networks to be flexibly and efficiently generated. The model is based on input parameters which are known to telephone network planners; thus, it can be applied without measuring specific network characteristics. The measured automatic speech recognition (ASR) performance degradation is compared to speech quality degradation in human-human communication
