2019 Chevrolet Silverado 2500HD Owners Manual - Voice Recognition

Voice Recognition

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

wheel or by selecting the g on the

screen 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 button presses such as selecting 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 pressing one or two buttons, and are not supported by voice commands.

In general there are flexible ways to speak commands for completing the tasks. Most of them, except destination entry and voice keypad, can be completed in a single command. If the task takes more than one command to complete, the first command would be to indicate the kind of task that is to be performed. The system replies with prompts that lead through a dialog to enter the necessary information.

Voice recognition can be used when the ignition is on or when Retained Accessory Power (RAP) is active.

See Retained Accessory Power (RAP) 0 251.

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 control to activate voice recognition, or select g on the infotainment display.

If voice recognition is started from the steering wheel control, the instrument cluster displays the selections and visual dialog content.

If voice recognition is started from the infotainment display, the selections and visual dialog content are displayed on both the infotaonment display and the instrument cluster display.

The audio system mutes and the system plays a prompt followed by a beep.

Wait until after the beep completes, then clearly speak one of the commands described in this section.

Press g to interrupt any voice recognition system prompt. For

example, if the prompt seems to be taking too long to finish, press g again and the beep should happen right away.

There are two voice prompt modes supported:

Long verbal prompts: The longer prompts provide more information regarding the supported actions.

Short prompts: The short prompts provide simple instructions about what can be stated.

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

Prompts and Screen Displays

While a voice recognition session is active, there will be corresponding buttons on screens displayed.

Manual interaction in the voice recognition session is permitted. Interaction during a voice session may be completed entirely using

voice commands, or some selections may expedite a session. If a selection is made using a manual control, the dialog will progress in the same way as if the selection was made through a voice command. Once the system is able to complete the task, or the session is terminated, the voice recognition dialog stops.

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

Press the Home screen button to terminate the voice recognition session which was initiated by pressing g on the infotainment display.

Press or say “Cancel” or “Exit” to terminate the voice recognition session and display the screen from which voice recognition was initiated.

. Press i on the steering wheel controls to terminate the voice

session and display the screen from which voice recognition was initiated.

Voice recognition can understand commands that are either naturally stated in sentence form (English only), or direct commands that state the application and the task.

For languages that do not support natural language commands in sentence form, use the direct commands shown as examples on the display screen.

For best results:

Listen for the prompt and wait for the beep before saying a command or reply.

Say “Help” or look at the screen display for commands.

Voice recognition system prompt can be interrupted during a prompt by pressing g again.

For example, if the prompt seems to be taking too long to finish, or if what is being prompted causes a need for an immediate reply, press g again

and wait for the beep.

Speak the command naturally, not too fast, not too slow. Use direct commands without a lot of extra words.

Usually Phone and Audio commands can be spoken in a single command.

For example, “Call Dave Smith at work,” “Play” followed by the artist or song name, or “Tune” followed by the radio station number.

There is no need to memorize specific command words. Direct commands might be more clearly understood by the system. An example of a direct command would be “Call 555-1212.” Examples of these direct commands are displayed on most of the screens while a voice session is active.

If “Phone” or “Phone Commands,” is

stated, the system understands that a phone call is requested and will respond with questions until enough details are gathered.

If the phone number has been saved with a name and a place, the direct command should include both, for example “Call Dave Smith at work.”

When a list is displayed, a voice prompt will ask to confirm or select an option from that list. A selection can be made by manually selecting the item, or by speaking the line number for the item to select.

When a screen contains a list, options may be available but not displayed. The list on a voice recognition screen functions the same as a list on other screens. Scrolling can be used to help display other entries from the list.

Manually scrolling or paging the list on a screen during a voice recognition session suspends the current voice recognition event and

plays the prompt “Make your selection from the list using the manual controls or press the Back button to try again.”

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

The Back Command

Say “Back” or press the Back button to go to the previous screen.

If in voice recognition, and “Back” is stated all the way through to the initial screen, then “Back” is stated one more time, the voice recognition session will cancel.

Help

Say “Help” on any voice recognition screen and the help prompt for the screen is played. Additionally, a

pop-up displays a text version of the help prompt. Depending on how voice recognition was initiated, the Help pop-up will either display on the instrument cluster or the

infotainment display. Press the Dismiss button to make the pop-up go away.

Pressing g while the help prompt is playing will terminate the prompt

and a beep will be heard. Doing this will stop the help prompt so that a voice command can be used.

Select the g screen button to launch audio voice recognition.

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 song titles by voice at the highest level if the number of songs exceeds the maximum limit.

Voice command option changes through media content limits are:

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

Album type folders including types such as albums and audiobooks.

There are no restrictions if the number of song files and albums is less than 4,000. When the number of song files connected to the system is between 4,000 and 8,000, 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 4,000 albums, but less than 8,000, 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 songs has exceeded approximately 8,000, 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 4,000.

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.

“Call ” : Initiate a call to an entered 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 an entered

contact and location at home, at work, on mobile device, or on another phone.

“Call ” : Initiate a call to a standard phone number seven or 10 digits in length, and also 911, 411, or 611.

“Pair Phone” : Begins the Bluetooth pairing process. Follow instructions on the radio display.

“Switch Phone” : Select a different phone for outgoing calls.

“Voice Keypad” : Begins a dialog to enter special numbers like international numbers. The numbers can be entered in groups of digits with each group of digits being repeated back by the system. If the group of digits is not correct, the command “Delete” will remove the last group of digits and allow them to be re-entered. Once the entire number has been entered, the command “Call” will start dialing the number.

“Voice Mail” : Initiate a call to voice mail numbers.

“OnStar” : Begin OnStar Voice Recognition.
