Not that any of this matters.  I can work around the repeating ATIS, but I can't work around getting my mic set up and working, responsive to speech-to-text in Windows, training text-to-speech to work better, then opening P2A, hearing ATIS, then tuning to clearance delivery, saying "Acey 4665 ready to copy" and getting no response at all, but working just fine when using "Say It."
Which is less than useless in VR.

I also get the distinct impression no one is reading this anyway, so this post is just a diary in frustration.

If SayIt is working, then most likely the problem is with the Mic or Mic settings.  I would focus on getting the Mic to work in Grammar Help first.  Once you get that working, you can try it with ATC.  (Sometimes an inexpensive 3.5mm jack headset is the solution.)

Here are some things you can check/try:

-  GRAMMAR HELP SCREEN AND DIAGNOSTICS: Try using the Grammar Help screen.  
⦁    Press the Grmr Help button to the right of the Flight Plan
⦁    Press the Practice button 
⦁    Take a screenshot of the resulting Message box with the connection information and email to me 
⦁    Try saying "Say Altimeter" with no other words.  It should be recognized.  Let me know the result.
⦁    If not being recognized, press the "Replay" button and see what your voice sounds like.  If no sound, then your voice is not getting through to Pilot2ATC.
- HEADSET SOUND SETTINGS: If you are using a headset, Windows may recognize that and put a set of "level" settings on the Levels tab of the Headphone Properties.  To set these, select the Headset in the playback devices Windows Settings and press "Properties". Select the Levels tab.  Be sure all levels are turned up as in this screenshot - notice the Microphone setting here on the Playback device:
- ADVANCED HEADSET / MIC SETTINGS: Be sure the Advanced tab of the Properties window for your default recording device has the sound format set to 2channel, 16 bit, and either 44,100 Hz or 48000 Hz (CD or DVD Quality).
- STERO MIX: Be sure that you have this turned off if it is an option.
- HEADSET AS DEFAULT PLAYBACK AND RECORDING DEVICE: If you have a headset mic set as the default Recording/Audio Input device, be sure and set the Headset as the Default Playback/Audio Output device.  Some users have had their microphone not working because  they set their Speakers as the Playback device.  
- NOISE CANCELLING HEADSET: If you have a noise cancelling headset like used in real aircraft to reduce engine noise, these may not work with the Speech Recognition.  Try using a standard PC headset.
- DEFAULT COMMUNICATIONS DEVICE: If using a headset as the default Playback/Recording device, be sure it is not also being used as the Default Communications Device.  This assignment of multiple duties seems to cause a problem.  Likewise, be sure the microphone is not assigned to any other duties besides the default audio input device.
-  SOUND DRIVERS AND ADD ON PROGRAMS - Many PCs come with Sound Add On programs from the manufacturer that are run at startup.  Some of these programs may "Capture" the microphone and prevent Pilot2ATC from hearing it.  Also, some addons may have such features.  Check to be sure there are not other sound programs running.  Also be sure that you have the latest Audio Drivers for your Microphone installed.
- REMOVE SONIC SUITE Check your PC for a program named Sonic Suite and remove it.  It prevents the Speech Recognition from working.  This is common on new PCs from ASUS and other manufacturers.
- Sound Bar or Other Sound Hardware AddOns Some users have reported that disconnecting sound hardware equipment like a Sound Bar or external speakers resolved the problem of a Mic not working.

So this is fun: Grammar Help works with the mic if I use the mouse to press the PTT button on the monitor.  I can say "Say Altimeter" and it hears it and plays it back.
I can set the button for PTT on my Honeycomb Alpha, and the PTT sound (that I have set) plays, meaning that the program appears to know to expect speech, but does not work with Grammar Help.
SayIt works fine when getting clearance outside of Grammar Help.
The mic still does not work when talking to ATC outside of Grammar Help.

Seems to work now.  Apparently after doing the Grammar Help, restarting 'fixed' it.

There's just so many variables anymore.

Providing more information.

Aaand now it doesn't again.

This is too frustrating.

Grammar Help only works with the on-screen PTT button, so your experience there was correct.

When using your PTT button with P2A's ATC, the PTT button on the main screen should turn green when you press the PTT hardware button on the Honeycomb Alpha.  If not, then the issue is with the PTT button setup.

If the PTT button is working, then the issue is with the Mic or Mic setup.  Going back through the earlier suggestions of things to check might be useful.  Sometimes, using an inexpensive 3.5mm jack headset works when others don't.
