+# WhisperTRT - ROS2 Node
+
+This example includes a ROS2 node for interfacing with WhisperTRT.
+
+It includes the full pipeline, including connecting to a microphone, and outputs recognized speech
+segments on the ``/speech`` topic.
+
+| Name | Description | Default |
+|------|-------------|---------|
+| model | The Whisper model to use. | "small.en" |
+| backend | The Whisper backend to use. | "whisper_trt" |
+| cache_dir | Directory to cache the built models. | None |
+| vad_window | Number of audio chunks to use in max-filter window for voice activity detection. | 5 |
+| mic_device_index | The microphone device index. | None |
+| mic_sample_rate | The microphone sample rate. | 16000 |
+| mic_channels | The microphone number of channels. | 6 |
+| mic_bitwidth | The microphone bitwidth. | 2 |
+| speech_topic | The topic to publish speech segments to. | "/speech" |
