In my Android app, I use tts.speak to play text with a pitch setting of 1.0 and speed of 1.0, and it works correctly. However, when I export the audio to a file using tts.synthesizeToFile with the same pitch and speed settings, the audio file is created successfully.

The exported audio plays correctly on some devices but sounds high-pitched and very fast on others.

Here are some additional details:

1. I am working with small text, not large.
2. I have tried with both internet connection on and off.
3. Some languages work, while others do not.
4. Voices that do not require an internet connection also do not work
   as expected.
5. Not using any deprecated functions.

Does anyone have suggestions on how to resolve this issue?
