My partner is from the midwest and has a "neutral American accent" while I'm from the south and have a slight southern accent. The irony is that even with the touch of drawl in my voice, I usually have more success with the VR than he does in both of our STSs.
I'm not sure what the difference is. Even my mom sometimes has a hard time telling us apart on the phone, so our voices are similar. He can say something several times and gets "pardon?" and I can say the same thing in the same way and it works for me the first time.
Maybe there are overtones to different peoples' voices that the human ear can't hear but the microphone picks up. I haven't been able to figure it out.
He says the car is kind of like me in that it isn't always good at listening when he's talking.
