Interacting with James

The user can give James instructions or ask questions using the following methods:

Voice Commands

James can be controlled by using voice-commands.

James will listen to pre-programmed voice commands after the wakeword "OK James" has been understood. Stand in front of the robot for the best results.

Supported languages

The currently supported languages on James are the following:

Language ASR / Listening TTS / Speaking




Thai (th-TH)






Arabic (ar-WW)



French (fr-FR)



English (en-US)



English (en-GB)



Dutch (nl-NL)



German (de-DE)






Chinese (zh-CN)



French (Canadian)



The language the robot will listen to can be set in the option speech-language of the kiosk. When connecting ZBOS Control and stating messages, only the TTS languages that the robot can speak will be shown.


The following speech-related settings can be found in the advanced-section of the settings in the Kiosk.

  1. Listen to voice-commands

  2. Rotate the robot when the wake-word is recognized

These options can be toggled on or off to suit the user’s needs.


The microphone at the bottom of the home-screen on the tablet can also be used as an indicator to see if James is listening.

Not listening



Prerequisites for the voice commands

Not all voice commands can be used all of the time. Some voice-commands will only be available once the following conditions have been met:

  1. Settings of the robot

The setting 'Spoken commands' in the general settings needs to be turned ON before the robot will respond to the wake-word "Okay James" and start listening.

If the option 'Spoken commands' is off, the option 'Rotate the robot when wake-word is recognized' will be greyed out and unable to be changed.
  1. Internet

Certain features require an active internet-connection to retrieve the latest data and to keep up-to-date.

For example:

  • Weather

  • Verklizan or VoIP/SIP

  • Installed apps

  1. VoIP

In addition to having a connection to the internet, a stable connection is needed to make calls using VoIP-services (the minimum bandwidth needed for a VoIP-call is between 85 and 100 kbps).

The section VoIP / SIP in the settings has been created to enter the account-information needed to call the Verklizan help center (or any other VoIP-service). A SIP-account needs to be registered at Verklizan before any VoIP-calls to their help-center can be made.
