Agreed 100%. Its why I've gender changed my Charr characters, the female Charr Commander voice just....grates on my nerves.
If you want a good example of what it SHOULD sound like, roll up a ranger and take it into PvP to try out the Untamed. Those Untamed specific voice lines sound perfect.
Its a shame, really. I think the body proportions on the female Charrs are way more aesthetically appealing.
