[Marvel] Does Human torch voice gets a higher pitch when he is on flames?

When Mr. Storm turns his powers on and gets super hot the air in his lungs also gets super heated. As heated air is less dense, it makes only sense to expect Mr. Storm's voice to get a higher pitch, just like when one of us normals inhale helium.
He hasn't given us a "flame on" interview, yet. But when he does should we expect a ballerina voice?

The Human Torch, when using his powers at full tilt, undergoes a full-body transformation into something that works on a completely different set of physics. This is why he can only fly when fully engulfed in flame- it's necessary to extend the reality warping effect of the cosmic rays to his entire body. This means that any assumptions about what he "should" sound like in that state are completely out the window.
