[Bug?] TTS of "10. 9. 8. 7. 6. 5. 4. 3. 2. 1. Finished" seems to clog the system

Describe the bug

Trying to get TTS to do a countdown, but it seems to run forever, when a similar prompt seems to run in a reasonable time

Works as expected: tts --text "How is the weather today?" --model_name "tts_models/en/ek1/tacotron2" --out_path test2.wav

Runs forever on my system: tts --text "10. 9. 8. 7. 6. 5. 4. 3. 2. 1. Finished" --model_name "tts_models/en/ek1/tacotron2" --out_path test3.wav

To Reproduce

run tts --text "10. 9. 8. 7. 6. 5. 4. 3. 2. 1. Finished" --model_name "tts_models/en/ek1/tacotron2" --out_path test3.wav

Expected behavior

Reasonable execution time
