OK, this doesn’t replicate for me in my test – I can speak, stop the speech at an arbitrary point, and say speech again afterwards using the same voice. That doesn’t mean I don’t think you’re seeing a real issue, just that it didn’t immediately replicate for me so there is maybe some other factor involved that I’ll need your assistance to see.
For further troubleshooting, the next step would be for you to create a minimal replication case to share with me, so I can see the exact thing you are seeing in your local setup:
