Khan, R., Ali, M., and Frank, E., "Analysis of Vehicle Voice Recognition Performance in Response to Background Noise and Gender Based Frequency," SAE Technical Paper 2017-01-1888, 2017.
Voice Recognition (VR) systems have become an integral part of the infotainment systems in the current automotive industry. However, its recognition rate is impacted by external factors such as vehicle cabin noise, road noise, and internal factors which are a function of the voice engine in the system itself. This paper analyzes the VR performance under the effect of two external factors, vehicle cabin noise and the speakers’ speech patterns based on gender. It also compares performance of mid-level sedans from different manufacturers.
