What happened?
When selecting the voice for Text-to-Speech, the selected Mistral AI voice (e.g., "Paul Natural Voice") is not used. Instead, the system silently fails and defaults to the standard, robotic iOS system TTS voice.
What should have happened?
The output should use the Mistral AI's specific voice model and tone (specifically "Paul Natural Voice"), providing a natural sound that is distinct from the system's default robotic iOS voice.
How to reproduce
Select the Any Mistral TTS settings.
Select a specific voice (e.g., "Paul Natural Voice").
Test.
Observe that the audio is played using the iOS system voice rather than the Mistral AI voice.
Does this happen every time?
Yes, every time
When did this start?
Never Worked.
