Did Whiz ever speak English anywhere besides Daredevil Versus Hitler #1, as that's the only place I've seen him do so so far.

Ok, I've had the chance to go thru the bulk of Silver Streak's appearances, and except for what seem to be misplaced word balloon pointers, Whiz doesn't seem to be speaking English (or any other language) until Daredevil #1. It's pretty clear from the context of those word balloons that they make more sense coming from one of the humans standing next to Whiz than from Whiz himself. Whiz disappears from the feature after Mickey/Mercury/Meteor is introduced in Silver Streak #11, except for reprints, until he appears in a new "untold" story in #23, set before the introduction of Mickey, and in that story, he was clearly shown speaking. I guess he actually did have the power of speech, even if he only seems to have used it in two stories.
