Voice command troubleshooting

Automatic Speech Recognition allows you to speak the city, street name and house number instead of entering the information via the touch screen. This requires your device to have a built-in microphone and to be using a computer voice.

The devices that can use this feature are:

  • GO 950 / GO 750 / GO 550
  • GO 940 / GO 740 / GO 540
  • GO 930 / GO 730 / GO 630 / GO 530
  • GO 920 / GO 720 / GO 520

If the speech recognition no longer works, we need to determine if the icon is greyed out or completely missing.

To check this, do the following:

  1. On your navigation device, in the Driving View , tap the middle of the screen.
  2. In the Main Menu, tap Navigate to...
    Navigate to...
  3. Tap Address .
    Address
  4. Here, you should see the Spoken address or Spoken address (dialogue) .
    Spoken Address
    Spoken Address
    (dialogue)

These icons do not display.


Sometimes the two menu options Spoken address and Spoken address (dialogue) are missing completely. This means that a file is missing from within your device.

This file can be replaced by redownloading it.

  1. Connect your navigation device to your computer.
    If your device does not start up or connect, press the power button for about 20 seconds until you hear the start up sound, then release the power button.
  2. Click here to download the file below and save it to your computer.
  3. On your computer, the file will have downloaded as 'support_asr.zip'. Extract the contents of this zip folder. You will now have a support_asr.dat file.
  4. Copy this support_asr.dat file by right clicking on it once and selecting Copy .
  5. Open your navigation device on your computer. How to do this depends on what operating system you use.

These icons are greyed out.

If the icons are greyed out in the menu then it means that files required for the speech recognition to function correctly are missing.

This means that the map needs to be downloaded from our servers. In order to redownload the map, the map must already be assigned to your account.

Important: If you are not sure if you have a map on your account, do not continue without ensuring you have a backup of your existing map. If you have an active Map Update Service subscription, you can remove the map and redownload it.

You need to redownload your map using TomTom HOME. See: Re-downloading a map (TomTom HOME)
