To avoid issues with your assistant's speech, always select the comma without a trailing space in the punctuation boundaries. If you accidentally select the comma with a space, remove it and use only standard punctuation marks as shown below:

json
"punctuationBoundaries": ",.!?;()-||:"

This ensures natural conversation flow and prevents audio quality problems. If you continue to see both options, it may be a UI oversight—consider reporting it to support for clarification or correction.
