Hello Greg,
just a heads-up to let you know that the CSS Working Group has reviewed this issue, and the consensus is to accept changing the markup from 'span' to 'em', as it makes more sense in the context of this particular example. However, the HTML default user-agent stylesheet remains out-of-scope (we will start a separate cross-group discussion for this).

As per the W3C process, you may choose to accept this resolution, or you may decide to raise an objection. Please let us know.

Kind regards, Dan

I also believe that this should be a concerted effort, which wouldn't really fit in the release timeframe for Level 3 of the CSS Speech Module.

In other words, I suggest to defer your proposal to include a " default user-agent stylesheet" informative appendix, and I would encourage a parallel activity to take place (e.g. within the realm of a W3C Community Group?).
