SAPI 4: TruVoice still doesn't quite work

[Mohamed00]

Steps to reproduce:

1. Install SAPI 4 along with the TruVoice speech synthesizer.
2. Press windows+d to go to the desktop.

Actual behavior:

An error occurs after "Desktop list" is spoken, and the desktop icon name isn't announced. This occurs in any situation where multiple strings are sent to NVDA.

Expected behavior:

No error, desktop icon name should be spoken.

Hi @gexgd0419 I got you a log using your try build of this behavior, which I believe is related to that demonstrated in issue #17776 but here I demonstrated how the LHTTS voices create the error sound, but not the lhtts3000 voices. Since it doesn't say it, it's Michael, Michel, the British Peter and I've forgotten the female British one's name. For most of it I cycled between the American Male Number 1 from TruVoice and the Mike in space from Microsoft voices, noting that tabbing onto the desktop with the mike voice behaves normally but tabbing onto it with Adult Male number 1 creates an error sound instead of saying the desktop icon. If it helps you jump around, the desktop icon is called 1drv (short for one drive). The main thing to look for is whether or not the voice was able to speak 1drv.

I can reproduce the problem with TruVoice on my side. Investigating.
