Silencing speech during a phone call

I posted this as a comment in the VIPhone google group: I find VO's speaking during a phone call annoying also. Here's an enhancement suggestion I have for the VO team: Add a VO setting option to turn VO speech off during a phone call. The setting would originally be off to be compatible with previous behavior. When a call comes in, the logic would be as follows: If the option is on, and VO speech is enabled, turn speech off. During the call: A three-fingered double tap would behave as normal during the call, that is, it would toggle speech. Call ends: If speech was turned off automatically at call start, and is currently off, turn it back on.
