- Remove condition that skipped word count check for empty/undefined STT text - Apply minInterruptionWords filtering uniformly to all speech scenarios - Normalize undefined/null transcripts to empty string for consistent handling - Update onEndOfTurn to use same splitWords logic as onVADInferenceDone - Add comprehensive test suite with 23 test cases covering: * Empty and undefined transcript handling * Word count threshold logic * Punctuation and whitespace handling * Integration scenarios between both methods This ensures consistent interruption behavior regardless of transcript content, preventing unwanted interruptions from silence or very short utterances. All 23 tests pass successfully.

Description
This PR resolves an inconsistency in the interruption detection logic for
minInterruptionWordswithin LiveKit agents. Previously, the word count check was skipped for empty or undefined STT transcripts, leading to unwanted interruptions triggered by silence or very short utterances.Now, interruption filtering based on
minInterruptionWordsis uniformly enforced across all speech scenarios, ensuring robust and predictable turn detection regardless of transcript content.Changes Made
minInterruptionWordsfiltering uniformly to all speech scenarios.onEndOfTurnandonVADInferenceDoneto use the samesplitWordslogic.All 23 tests pass successfully.
