That is some heavy accent. Those don't sound alike at all and I can't think of any accent that would make Herbert sound like Hanners. I think you have an unhealthy obsession.. go outside.
Your mom goes outside.
And I guess Hanners wasn't my first thought... it sounded more like Hannnnbaah and I was like "Hannah?" and she was "No, is Hhhaaannnbattt!" and I was like "Hanbat?" which made me think of Hanners. It was a Russian or Russian like accent, for what that's worth.
Also I should add that this is someone I rarely receive calls for and there are like fifty people on our switchboard.
