+- Added `vad_analyzer` parameter to `LLMUserAggregatorParams`. VAD analysis is now handled inside the `LLMUserAggregator` rather than in the transport, keeping voice activity detection closer to where it is consumed. The `vad_analyzer` on `BaseInputTransport` is now deprecated.

+  ```python
+  context_aggregator = LLMContextAggregatorPair(
+      context,
+      user_params=LLMUserAggregatorParams(
+          vad_analyzer=SileroVADAnalyzer(),
+      ),
+  )
+  ```
