Web Call Testing

Web Call testing bridges the gap between text chat and real telephony. It uses Verloop’s web SDK to connect your browser’s microphone directly to the Voice AI Agent, allowing you to test Speech-to-Text (ASR) and Text-to-Speech (TTS) performance without dialing a phone number.

​

Initiating a Web Call

1. Click the Play Icon in the Recipe Builder.
2. Select Test as Webcall.
3. A configuration popup will appear.

​

Configuration Options

You can configure the test in two ways:

​

Option 1: Test from Phone Settings

Select an existing phone number from your account. The system will auto-populate the specific Voice, Language, and Boosted Keywords assigned to that line.

• Best for: Regression testing an existing live agent.

​

Option 2: Custom Configuration

Manually tweak settings to experiment with new accents or languages.

• Language: Test how different models handle your script (e.g., switch between English (India) and Hindi).
• Voice: Audition different voices(e.g., Arjun vs. Riya) to see which tone fits your brand.
• Boosted Keywords: Add terms like “UPI” or “IBAN” to test if the ASR accuracy improves.

​

Simulating Context (Request Data)

Real calls often come with data (Caller ID, CRM info). You can simulate this in Web Call:

• Add Variable: Click + Add More in the test popup.
• Key/Value: Enter context like customer_name: "Rahul" or account_type: "Gold".
• Result: The AI Agent will start the call knowing this context (e.g., “Hello Rahul, thanks for being a Gold member”).

​

Debugging Web Calls

During the Web Call, the Chat Interface remains active.

• Live Transcript: Watch the ASR convert your speech to text in real-time.
• Debug Logs: If the agent misunderstands you, check the logs to see if it was a transcription error (ASR) or a logic error (LLM).
