Dynamic caption generation on a vehicle display unit

A method for dynamic caption presentation on a display unit of a vehicle, the method comprising:

• receiving, using control circuitry, speech data and background noise data at one or more microphones associated with a vehicle;
• receiving, using control circuitry, user interaction data indicating a first confidence level relating to assisting in a user's understanding the speech data, wherein the user interaction data comprises eye-tracking data indicating one or more portions of the display unit at which the user is looking, the display unit being configured to display captions;
• determining, using control circuitry, a second confidence level relating to a speech recognition system being able to accurately transcribe the speech data by separating it from the background noise data;
• receiving, using control circuitry, vehicle data indicating an operational state of the vehicle;
• determining, using control circuitry, that the first confidence level and the second confidence level are greater than respective first and second confidence thresholds, wherein the first confidence threshold is based on the operational state of the vehicle;
• and
• generating, using control circuitry, the captions for display on the display unit when the first confidence level and the second confidence level are greater than the respective confidence thresholds.
