Electronic voice alert (EVA) was an option available on many Chrysler K-car-based vehicles in the mid-1980s. Using technology from Texas Instruments similar to what was used in the Speak & Spell, the EVA would automatically lower the radio volume and deliver eleven different spoken warning messages (24 on certain models) to drivers using a speech synthesizer. Generally paired with a digital instrument cluster and considered the height of technology at the time, many drivers grew weary of the system constantly admonishing them to fasten their seatbelts and turned it off via removing a fuse. Later models had the option to be turned off via a switch in the glovebox.
