How to Build a Multilingual AI Voice Recruiter in 2026

Finding and screening talent across diverse regions requires speed and linguistic flexibility. Bolti, a voice AI platform for building production-ready conversational phone agents, helps you automate candidate screening in minutes. With support for over 80 languages and pricing at just ₹6/minute pay-as-you-go, you can deploy a highly responsive agent that speaks your candidate's language natively.

Whether you need to filter hundreds of resumes in Hindi, screen delivery partners in Marathi, or run high-volume BDR assessments in English, a multilingual AI voice recruiter ensures no quality candidate is left waiting. Here is how to build and deploy one.

What is a multilingual AI voice recruiter?

A multilingual AI voice recruiter is an automated phone agent that contacts or receives calls from candidates to conduct initial screening rounds. It behaves like a human coordinator: it asks qualifying questions, evaluates answers in real-time, and logs structured data back into your ATS.

Unlike traditional IVR systems or basic chatbots, a voice recruiter built on Bolti handles natural conversations. It understands regional accents, allows the candidate to interrupt, and responds in under a second.

How does a multilingual voice agent work?

To make a voice agent feel human, four distinct technologies work together in a millisecond-level pipeline. Bolti allows you to mix and match providers for each layer depending on your regional needs:

• Speech-to-Text (STT): Transcribes the candidate's spoken words. While Deepgram is the default for English, Bolti supports Fennec and Sarvam-backed STT to accurately capture Indian languages and regional accents (such as Hindi, Tamil, and Telugu).
• Large Language Model (LLM): The "brain" that decides what to say next based on the transcript. You can use major models like GPT-4o or low-latency open-source models like DeepSeek-V3.1 on Baseten's GPU infrastructure.
• Text-to-Speech (TTS): Converts the model's text response back into natural audio. Bolti integrates with top-tier TTS providers like Cartesia, ElevenLabs, and SarvamAI to deliver realistic voices.
• Telephony: Carries the call over standard phone networks. You can use Bolti's built-in numbers or bring your own SIP trunk (BYOC) through providers like Twilio, Exotel, or Plivo.

Step-by-step: Building your screening agent

Setting up a recruitment agent takes less than 15 minutes on the Bolti dashboard. Follow these steps to configure your first agent:

1. Define the agent's persona and prompt

In the agent configuration tab, write a clear system prompt. Instruct the agent on its role, the target job profile, and the exact qualifying questions it needs to ask (e.g., years of experience, notice period, and salary expectations).

2. Choose the right voice and language

Navigate to the Voice tab in your dashboard. Here, you will see a grid of preview-able voice cards showing the name, gender, language, and characteristics of each voice.

• Filter the grid by your target language (e.g., Hindi, English, or Tamil).
• Click the ▶ play button on a voice card (like Anushka from SarvamAI or Robyn from Cartesia) to stream a 3-second preview in its native language.
• Select the voice that matches your company's brand tone.

3. Connect your database or ATS

Use Bolti's open API and webhooks to pass candidate information before the call. You can inject variables like the candidate's name or the job title directly into the agent's prompt so the call feels personalized from the start.

Running high-volume outreach campaigns

Once your agent is configured, you do not have to dial candidates manually. Bolti's platform supports robust batch calling capabilities designed to handle large candidate pools efficiently.

With Bulk Campaigns, you can upload a list of hundreds of applicants. Bolti's scheduler and dispatcher pipeline will automatically place the calls at a controlled rate, respecting your workspace limits. If a candidate does not pick up, the system automatically handles retries based on your custom retry budget. All call outcomes, transcripts, and screening results are sent back to your system via webhooks.

Why choose Bolti over generic voice bots?

Recruitment calls are highly dynamic. Candidates hesitate, ask clarifying questions, or interrupt mid-sentence. Generic bots fail because they cannot handle these natural conversational patterns.

Bolti is built specifically for production-grade phone calls. It features sub-second turn-taking and real interruption handling, meaning if a candidate speaks while the agent is talking, the agent stops immediately to listen. Telephony-grade noise cancellation ensures that even if a candidate answers the call while walking on a busy street in Mumbai or Bengaluru, the agent transcribes their voice accurately.

Furthermore, Bolti's transparent pricing of ₹6/minute pay-as-you-go means you only pay for the exact duration of your screening calls, with no expensive upfront licensing fees. You can review our detailed pricing structure on the Bolti pricing page.
