It appears that a line was inadvertently deleted when the feedback was combined. Here's that section from the original draft, which clarifies that the sentence was referring to voice-balance, not voice-volume.

voice-volume: silent;
The spec should give an example of expected appropriate usage of this value. Because this generates a period of silence equal to the length of the would-be-spoken content, most listeners will just assume speech output has prematurely stopped. In radio terms, this is "dead air." How do you expect this value to be useful?

voice-balance:
Despite the at-risk status of this property, we believe it would be extremely useful for conveying context, particularly in situations such as two-party dialogue. 

Cheers,
James
