How to Add Voice AI Questions to Your Assessments

Before you begin

Make sure you have:

• A Testlify employer account with access to at least one assessment
• A microphone-enabled device (required for candidates using Web mode)

What is Voice AI?

Voice AI questions let an AI agent conduct a spoken interview with your candidates — evaluating communication, problem-solving, and customer service skills. Candidates respond either through their browser (Web mode, free) or via a live phone call (Call mode, charged at $0.18/min).

Add a Voice AI question

1. Log in to your workspace at app.testlify.com using your registered email and OTP.

   

2. Select the assessment from your dashboard where you want to add the Voice AI question.

   

3. Click Edit to open the assessment editor.

   

4. Go to the Questions tab.

   

5. Select Voice AI as the question type.

   

6. Configure the question:
   • Choose a sample question (the AI prompt is pre-filled), or enter a custom prompt.
   • Select an Answer Mode:
     • Web — candidate responds directly in the browser. Free.
     • Call — candidate provides their phone number and receives a call from the AI agent, simulating a live interview. Charged at $0.18 per minute. Learn more about the Call feature.

   

7. Click Add to include the question in your assessment.

   

8. Click Save to apply your changes.

   

Set up the AI prompt

You can provide the AI prompt in two ways:

Option A: Write manually

• Enter instructions directly in the AI Prompt field.
• Define how the AI should conduct the interview — tone, topics, and follow-up behavior.

Option B: Generate from a job description

1. Click Generate with file.

   

2. Upload the job description (PDF).
3. Optionally, add custom instructions to guide the AI further.
4. Click Generate.

   

Testlify builds a structured AI prompt from the job description, ensuring consistent, role-relevant questions for every candidate.

Tip: Use Generate with file for role-specific interviews — it tailors questions to the exact skills and responsibilities in your job description, so you spend less time writing prompts.

How candidates experience Voice AI

• The candidate receives an invite and starts the assessment.
• The AI agent asks questions in a natural voice.
• The AI interacts with and records the candidate's responses.

  

• After the candidate submits, their responses appear on the candidate results page for your review.

  

Frequently asked questions

• Do candidates need special software or apps? No — only a stable internet connection and a microphone.
• Can I customize the AI prompts? Yes. Use a sample question or write a fully custom prompt for any role.
• Are responses recorded? Yes. All responses are recorded and available in the candidate results section.
• Can I use Voice AI for any role? Yes — it works well for customer service, sales, tech support, and any role where communication skills matter.
