Robovoice Backlog

Second-order PTT

When a game is running, it has its own PTT button (e.g. a voip push-to-talk key). Robovoice should simulate pressing the game's PTT key before TTS audio output begins, and release it after playback finishes.

This lets the TTS audio be transmitted through the game's voip channel to other players.

Considerations

• Needs a configurable "game PTT key" (separate from Robovoice's own PTT key)
• Use SendInput or keybd_event to synthesize the keypress
• Press the game PTT key right before buffered audio starts playing
• Release it after AudioOutput finishes playback (need a playback-complete signal — currently Flush() doesn't provide one)
• Edge cases: what if the user presses Robovoice PTT while game PTT is still held from a previous utterance? Flush should release game PTT too.
• Should this be a per-output-device setting? (CABLE Output vs speakers)
