alt Hacker NewsYou.know, this is very funny to me. Back in the early 90s, when mobile moved from analog to digital, I bought the first Motorola digital flip phone. And it regarded my voice as "noise" over a certain level, which (as I have a loud voice), meant it was clipping all the time.
I engaged Motorola on this, spoke with the engineering team. We even did a few calls, me with a Nokia and then a Motorola so they could see the difference. You could sense the shoulder shrugs at their end.
To discover they still have the same limitations is beyond amusing, and I wonder of the same engineering team still exists in part, decades later, refusing to care.
I'm sure this isn't actually what happened, but when you said "as I have a loud voice" and then "did a few calls" and finally "shoulder shrugs at their end", I imagine you shouting over the phone to them, and them not understanding why your are shouting instead of just talking :P I'm sure it wasn't like that though, just what popped into my head.
Maybe this isn't any of my businesses, but couldn't you just talk less loudly, if this is such a issue? Most microphones are good enough, and were in the 90s too, to pick up normal conversational volume :)
