Test your voice-enabled copilot

You can test your copilot with text inputs that simulate the end user’s input from speech or DTMF and see the speech response in the text output.

You can switch chat mode into Speech & DTMF to test voice features.

Known limitations

• Speech recognition, since there's no speech input.
• Multi-DTMF grammar validation and timers, such as digit length.
• Silence detection timer, reprompt, and fallback behavior.

Configure your test voice-enabled copilot

When you use Test copilot in chat in Speech & DTMF mode, you can get the copilot’s speech response through text output. A Speech & DTMF modality message is used over a text modality.

Different ways to test

You can test for different scenarios to anticipate expected outcomes in the chat:

• Set voice variable values to simulate a real phone call.

  For example, to simulate caller ID, you can manually set the variable value for conversation start by inputting “/debug set variable-name variable-value.”

  Variable name	Type	Description
  Activity.From.Name	String	Customer caller ID
  Activity.Receipient.Name	String	Voice copilot number
  Conversation.SipUuiHeaderValue	String	SIP header value for transfer-in context
  va_CustomerLocale	String	Locale value for routing to another voice that supports the desired language. This value requires you to install the OC extension solutions.
  va_SurveyConsent	Boolean (true/false)	- If the customer consents, the call is automatically transferred to the post-call survey copilot at the end of the personal digital assistant call. - If set to false, the call ends when the copilot hangs up, which requires you to install the OC extension solutions.

• If you created an SSML message for your voice-enabled copilot, you can see the text output without SSML.

• If the question node is enabled for Read out, you see the text output for multiple choice options, closed list entity options, and dynamic list variables. For example, you might get you can say book a flight or check flight status.

  

  If options accept DTMF input, you see the output for each option as Press 1 or say book a flight or Press 2 or say check flight status.

• For messages with barge-in disabled, you see Barge in is not allowed.

  

• For a long running operation latency messages, you receive a standard copilot message once. Instead of looping, the message displays until the operation completes when it plays back in the Telephony channel.

• For single DTMF, you can press a key in dial pad, or type in a command to trigger global commands, and the select menu options. You can type “/DTMFkey 1,” which is treated as if the user provided a single DTMF option “1.” Depending on the conversation state, the copilot can either proceed with option 1’s choice from the question node or trigger a global command, if applicable.

  

  Note

  Dialpad input only supports single-digit DTMF.

• For Multi DTMF, you can only use the command "/DTMFkey DTMF keys." For example, /DTMFkey 123, to simulate batched, multi-digit DTMF.

  Speech input might skip the speech recognition part of the system. Test chat doesn’t validate DTMF grammar, such as DTMF length, timer, term key, and DTMF caching.

  Tip

  Don’t input DTMF keys with term key as saved responses with all the DTMF keys.

• When transferring to a phone number or personal digital assistant, contexts that are passed display in the popup. Select View details for more information.
