AI Voice Agents

Human-sounding AI voice agents for inbound and outbound calls at scale.

We build voice AI that answers, calls, books, qualifies and collects — with sub-second latency, natural prosody and full CRM integration.

Overview

Voice is the highest-friction, highest-value channel in most businesses. T7 Solution builds AI voice agents that replace IVR trees, handle overflow, and run outbound campaigns — 24/7, in multiple languages.

Our stack combines best-in-class speech-to-text, LLM reasoning and neural TTS with telephony (Twilio, Plivo, Exotel) and CRM (Salesforce, HubSpot, Zoho) — so every call is grounded in real customer context and logged automatically.

We measure connect rate, containment rate, conversion and QA scores — and tune the agent weekly.

Challenge

Front-desk staff were missing 30% of after-hours booking calls, no-shows were running above 20%, and callers dropped off IVR trees before reaching the right department.

Solution

T7 deployed a bilingual (English + Hindi) voice agent on Exotel — handling appointment booking with live calendar sync, running outbound reminder + confirmation calls the day before, and warm-transferring anything clinical to a human. Full HIPAA-aligned recording lineage.

Result

After-hours booking capture went to 100%, no-show rate dropped from 22% to 9%, and cost per booked appointment fell roughly 4x versus the previous BPO-assisted flow.

"The AI books slots, reminds patients, and only escalates the calls that actually need a clinician. Our front desk finally has time to look people in the eye again."

Frequently asked questions

Will callers know they're talking to AI?

We recommend disclosing when required by law. Our agents sound natural but we design for transparency and easy human handoff.

What languages do you support?

30+ languages with regional accents. Indian-language support (Hindi, Gujarati, Tamil, etc.) is a core strength.

Can it take payments over the phone?

Yes, via PCI-compliant DTMF capture or by sending a secure payment link mid-call.

What about noisy environments?

We use noise suppression, VAD tuning and confirmation prompts to stay accurate on low-quality lines.

What's the real end-to-end latency?

Median voice-to-voice is under 800 ms on Twilio/Plivo with our optimised pipeline (VAD + streaming STT + streaming LLM + streaming TTS). Below ~700 ms conversations feel indistinguishable from a human on pacing.

How do you handle interruptions and barge-in?

Full duplex with barge-in from day one — the agent stops speaking the moment the caller starts, resumes gracefully, and never talks over them. This alone is what separates natural-feeling voice AI from IVR.

Which telephony providers do you integrate with?

Twilio, Plivo, Exotel, Vonage, Telnyx, and any SIP-compatible carrier. For India we default to Exotel or Plivo for local-number regulatory compliance.

How is this priced at scale — per minute or per seat?

Voice AI is priced per usable minute (talk time). Our stack typically lands at $0.06–$0.12 per minute all-in including STT, LLM, TTS and telephony — a fraction of a BPO seat cost.

Can it run outbound campaigns compliantly?

Yes, with DNC scrubbing, per-region calling windows, consent capture, opt-out handling and full recording lineage. We honour TRAI, TCPA and GDPR requirements out of the box.

What about warm transfers and post-call CRM updates?

The agent can conference in a human agent with a spoken summary and full transcript, and it writes the disposition, notes and next-action back into Salesforce, HubSpot, Zoho or your CRM automatically.
