Providing a Custom Help Prompt

In Vocera Voice Server 5.2.3 and later, the Help voice command allows you to interact with the Genie in natural language to receive information about voice commands and device features. Vocera recommends taking advantage of the built-in natural language capabilities of the system to provide user help. The rest of this section shows you how to override these built-in capabilities to provide a custom response to the Help command.

When you use this override capability, you record a custom Help prompt as a WAV file and place it in a specific folder on the Vocera Voice Server. The custom prompt then responds to the Help command, overriding it and providing users with specific site-based information (for example, the prompt could direct users to a Vocera super user, an administrator, an internal Web site, or a local help desk for assistance).

Note: If you already have a custom help prompt and want to take advantage of the built-in natural language help capabilities, remove the custom prompt from the Vocera Voice Server and the system will begin using the natural language help capability.

To provide a custom Help prompt for your Vocera system:

  1. Create a WAV file named help_top_level.wav.
    The WAV file must use the required audio format and sampling rate. See Required Format of Audio Prompt Files.
  2. Place the help_top_level.wav file in the following folder on the active Vocera Voice Server:

    \vocera\data\prompts\custom

    Important: Before putting a WAV file onto a production Vocera Voice Server, you should always test it first on a staging server. If the Nuance service is unable to play a WAV file because it was recorded incorrectly, the service throws an exception, which causes the Vocera Voice Server to restart.
  3. If you have a Vocera Voice Server cluster, restart the standby nodes to force a remote restore. This causes the custom Help prompt to be replicated on the standby nodes.
  4. To test the help prompt, log into a Vocera badge and say the command, "Help."
    The badge should play your custom WAV file.
Note: If the help_top_level.wav file is missing from the \vocera\data\prompts\custom folder, when a badge user says the "Help" command the system uses the standard Help prompt: "No help is currently available."
