AI Voice Agents: How They Work, Use Cases & Pricing

AI voice agents are software programs that make and answer phone (and video) calls in a natural, human-like conversation — understanding what a person says, and increasingly how they say it. This guide explains how they work, what they're used for, what they cost, and how to evaluate one.

What is an AI voice agent?

An AI voice agent is an autonomous system that holds a spoken conversation over a phone or video call without a human operator. It combines three layers: speech-to-text (to hear), a large language model (to understand and decide what to say), and text-to-speech (to reply in a natural voice). Modern agents like Auris AI add an emotion layer that reads tone, sentiment, hesitation and confidence — so the agent responds to how someone feels, not just the words.

How do AI voice agents work?

A typical call flows through four steps:

1. Train the agent — upload a knowledge base, set the persona and tone, and define empathy thresholds. No code required.
2. Configure the flow — map triggers, escalation rules, and integrations with your CRM, ATS or HRMS.
3. Launch at scale — agents run 24/7; every call is recorded, transcribed and emotion-scored in real time.
4. Analyse and act — behaviour dashboards surface patterns, and outcomes are pushed automatically into your workflow.

What are AI voice agents used for?

Auris AI runs nine use cases live in production, across hiring, outbound, inbound and intelligence:

• HR Interview — Round 1: screen candidates on a first-round call and score them automatically.
• Video Interview: conduct video interviews, read engagement, and score candidates.
• Lead Calling: call large outbound lead lists automatically.
• Campaign Calling: launch calling campaigns to every contact, hands-free.
• Employee Feedback: capture honest feedback in a conversation, not a form.
• Customer Support: resolve inbound support calls without a human agent.
• Conversation Behaviour Analysis: detect when tone contradicts words.
• AI Resume Scoring: rank hundreds of resumes against job context in minutes.
• App Integrations: update the CRM, notify Slack and raise tickets after each call.

How much do AI voice agents cost?

Pricing models vary, but the most transparent is usage-based. Auris AI charges ₹9 per minute for voice and video sessions with no minimum commitment and no lock-in, plus a one-time ₹75,000 setup (configuration, agent training, knowledge base, go-live support). Implementation is custom-quoted after a discovery call. For context, 1,000 calls a month at ~8 minutes each costs about ₹72,000/month in usage — still well below a human calling team (~₹1.1 lakh/month for the same volume), and it scales to 100,000 calls with zero extra headcount. Prices exclude GST.

Do AI voice agents support Indian languages and Hinglish?

Yes. Auris AI agents speak English, Hindi and Hinglish — a natural Hindi-English mix that's how many Indian customers and candidates actually talk. This makes calls feel human rather than robotic, which improves pickup and completion rates.

How is an AI voice agent different from an IVR or voice bot?

Traditional IVRs and scripted voice bots talk at people with rigid menus. An emotion-aware AI voice agent listens first, adapts in real time, reads sentiment, measures conversation quality (not just call volume), and pushes insight into your workflow. Auris AI is also the only platform combining AI voice calls and video interviews in one product.

What should you look for when choosing an AI voice agent?

• Emotional intelligence — does it score tone, sentiment and hesitation, or only transcribe?
• Language fit — does it handle your customers' real languages (e.g. Hinglish)?
• Integrations — does it push outcomes into your CRM, ATS, HRMS, Slack and WhatsApp?
• Security — data residency controls, audit logs, role-based access, SOC2-aligned infrastructure.
• Transparent pricing — pay-per-use with no lock-in beats long subscription contracts.
