In-car voice control lets the driver place calls, pick stations or play music by spoken command, in newer systems even in natural sentences. Some makers house it in a module of its own: FCA put Uconnect voice recognition into a hands-free module (HFM) on 2012–2017 Journey, Charger and 300; with old software it could hang while loading, ignore the steering-wheel voice key or pick up background noise, and a reflash fixed it (08-055-17 REV. A, where a silent HFM sets U0197). Ford runs voice commands on the SYNC computer (APIM). U0564 is set when a dedicated speech recognition module sends data that fail checks; U0263 covers lost contact. No manufacturer documents U0564 publicly. Voice commands may be ignored, misread or cause wrong actions.

Likely causes

Speech recognition software outdated or faulty (fixed by reflashing)

Unsupported language selection or mismatch between module and head unit settings

Speech recognition module internally faulty

Symptoms

Voice control does not respond to the steering-wheel button
Voice commands misrecognized or system stuck while loading
