Thanks for your interest in Riva,
Thanks for sharing the Riva Client Version, 0.0.5 does not support confidence scores
The latest riva-client supports confidence, current latest is 2.8.0
Please upgrade the python package
pip install --upgrade nvidia-riva-client
and you will be able to see confidence in your python transcript output
Let me know if you face any issues
Regards,
Roshandev
