Build a Custom AI Recruiter Voice Agent for Phone Screens

An ai recruiter voice agent is a conversational AI system designed to conduct automated, real-time phone screens at the top of your hiring funnel. Bolti, a voice AI platform for building production-ready conversational phone agents, lets you set up these agents to call candidates, ask job-specific questions, and parse resumes starting with a free trial that includes 50 minutes.

Instead of wasting hours playing phone tag or scheduling 15-minute introductory chats, your team can deploy an AI recruiter voice agent to handle initial candidate screening. The agent reads your job description, reviews the candidate's CV, conducts a natural voice interview over the phone, and structures the feedback directly for your recruiting team.

Why use an AI recruiter voice agent for candidate screening?

Using an AI recruiter voice agent solves the most painful bottleneck in modern recruiting: high-volume, low-yield phone screens. When you have hundreds of applicants for a single role, manual screening is slow, inconsistent, and highly prone to bias.

Automating this stage with Bolti provides three distinct advantages:

• Zero scheduling friction: You do not need to send back-and-forth emails to find a slot. Bolti can trigger an outbound call instantly or let candidates self-book a call via a scheduling link.
• Consistent evaluation: Every candidate is asked the same core set of qualifying questions based on your job description, ensuring a level playing field.
• Instant turnaround: You can screen 500 candidates in parallel within an hour, rather than stretching the first-round screen across three weeks.

How the voice AI recruitment pipeline works

Every call handled by a Bolti voice agent relies on a highly optimized, sub-second loop that makes the conversation feel as natural as talking to a human recruiter. This system is split into four distinct stages that work together in real time:

1. Speech-to-Text (STT): The candidate speaks, and Bolti's pipeline transcribes their voice instantly. For Indian accents and regional languages, you can select specialized engines like Fennec or Sarvam.
2. Large Language Model (LLM): The transcribed text is processed by the underlying model (such as GPT-4o, Gemini, or Groq), which evaluates the candidate's response against your job description and custom questions.
3. Text-to-Speech (TTS): The agent's reply is synthesized back into high-quality audio using natural voice engines like ElevenLabs, Cartesia, or SarvamAI.
4. Telephony & Turn-Taking: Bolti's built-in Voice Activity Detection (VAD) and telephony-grade noise cancellation ensure the agent understands when the candidate stops speaking, handles interruptions naturally, and filters out background noise.

Step-by-step: Setting up your screening agent in Bolti

Creating an automated screening funnel on Bolti is straightforward and requires no coding. The platform organizes this workflow using a structured "Role" and "Candidate" model.

Step 1: Create the role

Navigate to Agents → HR Screening in your Bolti dashboard and click + New Role. Here, you will enter the official role title (e.g., "Senior Backend Engineer") and paste the full job description. The agent will use this job description verbatim to understand the required tech stack, responsibilities, and must-haves.

Step 2: Configure your screening variables

To ensure your agent has all the context it needs, Bolti uses four template variables that map candidate and job details directly into the agent's system prompt:

• {{ candidate_name }}: Automatically filled with the candidate's name parsed from their CV.
• {{ jd_text }}: The job description you provided in Step 1.
• {{ custom_questions }}: A specific list of questions you want the agent to ask.
• {{ candidate_details }}: Bullet points summarizing the candidate's resume.

Simply include these Jinja-style braces in your agent's system prompt (e.g., "You are screening {{ candidate_name }} for the {{ jd_text }} role. Ask these questions: {{ custom_questions }}"), and Bolti will handle the rest.

Step 3: Upload candidate CVs

Upload a batch of candidate resumes in PDF format. Bolti's parser automatically extracts the raw text, summarizes the resume into refined bullet pointers, and populates your candidate table.

Step 4: Launch your outreach

You can initiate screens in two ways: schedule immediate outbound calls to a list of phone numbers, or send a self-booking link via SMS or WhatsApp. When a candidate selects a time, Bolti calls them automatically.

Customizing the recruiter's voice and personality

Your voice agent is often the first interaction a candidate has with your company, so its tone matters. In Bolti's Voice tab, you can choose from a wide grid of curated voice cards to match your company's brand.

• Filter by characteristics: Search for voices tagged as professional, warm, energetic, or empathetic.
• Multilingual support: Choose native voices across English, Hindi, Marathi, Tamil, Telugu, Gujarati, and over 80 other global languages to match your local hiring needs.
• Live previewing: Click the play button on any voice card in the dashboard to stream a 3-second preview before committing it to your active agent.

Frequently Asked Questions

Can the AI recruiter voice agent handle candidate interruptions?

Yes. Bolti features built-in interruption handling and voice activity detection (VAD). If a candidate starts speaking while the agent is talking, the agent stops immediately, listens to the input, and adjusts its response naturally.

How does the agent know what questions to ask?

The agent pulls questions dynamically from the role configuration using template variables. It combines your custom questions, the job description, and the candidate's parsed resume to ask highly relevant, contextual questions.

Which languages does the AI recruiter support?

Bolti supports over 80 languages, including English, Hindi, Marathi, Tamil, Telugu, Bengali, Gujarati, and Kannada. You can configure different STT and TTS engines per agent to match local candidate demographics.

Does Bolti integrate with my existing Applicant Tracking System (ATS)?

Yes. Bolti is built with an open API and REST architecture. Every action you perform in the dashboard can be triggered via API calls, allowing you to sync candidate statuses, call recordings, and structured transcripts directly with your ATS.
