2021 Chevrolet Silverado 2500HD Owners Manual - Voice Recognition

Voice Recognition

If equipped, voice recognition allows for hands-free operation within the navigation, audio, phone, and weather applications. This feature can be started by pressing g on the

steering wheel or touching g on the

infotainment display.

However, not all features within these areas are supported by voice commands.

Generally, only complex tasks that require multiple manual interactions to complete are supported by voice commands.

For example, tasks that take more than one or two touches, such as a song or artist to play from a media device, would be supported by voice commands. Other tasks,

like adjusting the volume or seeking up or down, are audio features that are easily performed by touching one or two options, and are not supported by voice commands.

In general there are flexible ways to speak commands for completing the tasks.

If your language supports it, try stating a one-shot command, such as “Directions to address .” Do not include the ZIP code while stating the address during the command. Another example of a one-shot Destination Entry command is, “Directions to Place of Interest at .” If these commands do not work, try saying, “Take me to Place of Interest” or “Find address” and the system will walk you through by asking additional questions.

If equipped, this feature helps distinguish words by using Internet-based information along with the system’s voice recognition database. This allows you to speak more naturally when using voice recognition.

Voice recognition becomes available once the system has been initialized. This begins when the ignition is turned on. Initialization may take a few moments.

Press g on the steering wheel controls to activate voice recognition.

The audio system mutes and the system plays a prompt.

Clearly speak one of the commands described in this section.

A voice recognition system prompt can be interrupted while it is playing by pressing g again.

Once voice recognition is started, both the infotainment display and instrument cluster show the selections and visual dialog content. These displays can be turned on or off in the Tutorial Mode under Settings

0 181.

There are three voice prompt modes supported:

. Informative verbal prompts: This type of prompt will provide more information regarding the supported actions.

Short prompts: This type of prompt will provide simple instructions about what can be stated.

Auto informative prompts: This type of prompt plays during the first few speech sessions, then automatically switches to the short prompt after some experience has been gained through using the system.

If a command is not spoken, the voice recognition system says a help prompt.

Prompts and Infotainment Displays

While a voice recognition session is active, there may be corresponding options showing on the displays. A selection can be made by manually touching the option,

or by speaking the number for the option to select. Manual interaction in the voice recognition session is permitted. Interaction during a voice session may be completed entirely using voice commands while some manual commands may expedite a task. If a selection is made using a manual control, the voice recognition dialog will progress in the same way as if the selection were made using a voice command. Once the system completes the task, or the session is terminated, the voice recognition dialog stops.

An example of this type of manual intervention is touching an entry of a displayed number list instead of speaking the number associated with the entry desired.

Touch or say “Cancel” or “Exit” to terminate the voice recognition session and show the display where voice recognition was initiated.

Press i on the steering wheel controls to terminate the voice recognition session and show the display where voice recognition was initiated.

Natural Language Commands

Most languages do not support natural language commands in sentence form. For those languages, use direct commands like the examples shown on the display.

Voice recognition can understand commands that are naturally stated in sentence form or direct commands that state the application and the task.

For best results:

Listen for the prompt before saying a command or reply.

Speak the command naturally, not too fast, not too slow.

Use direct commands without a lot of extra words. For example, “Call at work,” “Play” followed by the artist or song name, or “Tune” followed by the radio station number.

Navigation destinations can be made in a single command using keywords. A few examples are: “I want directions to an address,” “I need to find a place of interest or (POI),” or “Find contact.”

The system responds by requesting more details. For other POIs, say the name of a category like “Restaurants,” “Shopping Malls,” or “Hospitals.”

Navigating to a destination outside of the current country takes more than one command. The first command is to tell the system where the navigation will take place, such as an Address, Intersection, POI, or Contact. If Address or Intersection is selected, the second command is to say, “Change Country.” Once the system

responds, say the country before saying the rest of the address and/or intersection.

If POI is asked for, say “Change Location,” then “Change Country.”

Direct commands might be more clearly understood by the system. An example of a direct command would be “Call .” Examples of these direct commands are displayed on most of the screens while a voice session is active. If “Phone” or “Phone

Commands,” is spoken, the system understands that a phone call is requested

and will respond with questions until enough details are gathered to make a call.

If a cell phone number has been saved with a name and a place, the direct command should include both, for example “Call

at work.”

When a list is displayed, a voice prompt will ask to confirm or select an option from

that list.

When a display contains a list, there may be options that are available but not displayed. The list on a voice recognition screen

functions the same as a list on other displays. Scrolling or flinging can be used to help display other entries from the list.

Manually scrolling or paging the list on a display during a voice recognition session suspends the current voice recognition event and plays the prompt “Please select manually or touch the Back icon on the infotainment display to try again.”

If manual selection takes more than 15 seconds, the session terminates and prompts that it has timed out. The display returns to the display where voice recognition was initiated.

The Back Command

Say “Back” or touch the Back icon on the infotainment display to go to the previous menu.

If in voice recognition, and “Back” is spoken all the way back to the starting display, and then “Back” is spoken one more time, the voice recognition session will cancel.

Help

Say “Help” on any voice recognition display and the help prompt for the display is played.

Handling Large Amounts of Media Content

It is expected that large amounts of media content will be brought into the vehicle.

It may be necessary to handle large amounts of media content in a different way than smaller amounts of media. The system may limit the options of voice recognition by not allowing selection of files by voice at the highest level if the number of files exceeds the maximum limit.

Changes to voice commands due to media content limits are:

Files including other individual files of all media types such as songs, audiobook chapters, podcast episodes, and videos.

Album type folders including types such as albums and audiobooks.

There are no restrictions if the number of files and albums is fewer than 12,000. When the number of files connected to the system

is between 12,000 and 24,000, the content cannot be accessed directly with one command like “Play .”

The restriction is that the command “Play Song” must be spoken first; the system will then ask for the song name. The reply command would be to say the name of the

song to play.

Similar limits exist for album content.

If there are more than 12,000 albums, but fewer than 24,000, the content cannot be accessed directly with one command like, “Play .” The command “Play

Album” must first be spoken; the system

will then ask for the album name. The reply

would be to say the name of the album to play.

Once the number of files has exceeded approximately 24,000, there is no support for accessing the songs directly through voice commands. There will still be access to the media content by using commands for playlists, artists, and genres.

The access commands for playlists, artists, and genres are prohibited after the number of this type of media exceeds 12,000.

The system will provide feedback the first time voice recognition is initiated if it has become apparent that any of these limits are reached during a device initializing process.

Voice recognition performance will degrade to some extent based on many factors when adding large amounts of data to recognize. If this is the case, perhaps accessing songs through playlists or artist name would work better.

“Navigation” : Begin a dialog to enter specific destination information.

“Navigation Commands” : Begin a dialog to enter specific destination information.

“Address” : Begin a dialog to enter a specific destination address, which includes the entire address consisting of the house number, street name, city, state/province,

and country. Do not include the ZIP code.

“Place of Interest” : Begin a dialog to enter a destination Place of Interest category or major brand name.

The name must be precisely spoken. Nicknames or short names for the businesses will not likely be found. Lesser known businesses might have to be located by category, such as fast food, hotels,

or banks.

“Navigate to Contact” : Begin a dialog to enter a specific destination contact name.

“Cancel Route” : End route guidance.

“Take Me Home” : Create a route to a stored home location.

“Call ” : Initiate a call to a stored contact. The command may include location if the contact has location numbers stored.

“Call At Home,” “At Work,” “On Mobile,” or “On Other” : Initiate a call to a stored contact and location at home, at work, on mobile device, or on another phone.
