+
+**Technical Details:**
+
+The Arm Analytics demo leverages machine learning for real-time audio recognition:
+
+- **ML Framework**: The demo uses :ref:`TensorFlow Lite (LiteRT) <tflite-label>` as the deep learning runtime for efficient on-device inference on Arm Cortex-A cores
+- **Pipeline Management**: :ref:`NNStreamer <nnstreamer-label>` is used to manage the neural network pipeline, providing seamless integration between audio capture and ML inference through GStreamer plugins
+
+For more information on the underlying technologies:
