Operation of the OnStar® Speech Recognition Systems

OnStar® users communicate with 2 speech recognition systems. Speech recognition allows the user to speak to one computer in the vehicle and one reached over a phone line. The computer tries to understand the users command and responds by speaking back or by taking the appropriate action, e.g. dialing the phone.

• Personal Calling uses a speech recognition system that resides in the vehicle. When the user presses the phone button, the system states, Ready and listens for the user's command. The user can speak commands to control the hands-free phone.
• Virtual advisor is a remote speech recognition system that the caller can access by making a phone call. The user connects to virtual advisor by requesting it during personal calling use. The user is then transferred to the virtual advisor server and talks to it via a cellular connection.

The OnStar® speech recognition systems use speech technology that is designed to understand a wide range of American English speakers. Although there is no one right way to speak English, the system will work best when users try to modify their pronunciation should they encounter difficulty. Users who do not obtain good results are advised to try the tips and workarounds found in the Infotainment System Manual or the Owners Manual.
