This is only recently happening, a few updates ago. For example, my doorbell sends TTS to a speaker. It will basically cache every time its used. So if you push once it will say once. Then if you push again, it will say twice, 3,4,5.... My doorbell now does TTS about 100 times 😂 I tried clear TTS Cache, but it didn't do anything 😦
Im using Piper, but this also happened with Google TTS.
