How it works

From first call to
production in weeks.

A structured engagement designed to move fast without cutting corners — you see working software at every stage.

01

Discovery & Stack Decision

We map your call flows, data sources, and compliance requirements. Together we decide: build a custom sovereign stack or deploy NextNeural — the pre-built voice AI platform.

02

Voice & Telephony Design

We select and fine-tune ASR/TTS models, clone your brand voice, integrate your SIP or telephony provider, and architect the low-latency serving layer.

03

Agent & Workflow Build

Conversational agents are built with tool access to your databases, documents, and web sources. Inbound and outbound campaign flows are wired and tested on real call traffic.

04

Deploy & Hand Off

Production deployment with call recording storage, transcript pipelines, structured data exports, and a full knowledge transfer so your team owns the stack.

The progression

Start where you are.
Build toward the frontier.

We meet you at your current maturity level and build a clear path forward — from foundational implementation to research-grade capability.

In the real world

What this looks like
when it's running.

Real scenarios, real numbers. The specifics change — the pattern is consistent.

BFSI

A microfinance company runs 30,000 daily EMI reminder calls in Hindi — with a sovereign AI stack that also captures structured responses from customers about preferred payment dates, repayment intent, and financial constraints, feeding directly into their CRM.

Higher collection rates, richer borrower data, zero third-party data exposure
SaaS

A SaaS platform streamlined its outbound sales pipeline by connecting voice AI directly to its leads database — automatically qualifying prospects, handling objections, and booking discovery calls with sales reps.

3× pipeline throughput, no SDR headcount added
E-commerce

A retailer reduced cart drop-off by deploying a voice agent that proactively reaches out to hesitant shoppers — answering product questions in real time using live catalogue, personalised transaction history, and recommendation data.

Significant reduction in cart abandonment, higher conversion on outreach
What you get

Shipped artifacts,
not slide decks.

Every engagement ends with working software, documented systems, and a team that knows how to extend them.

Sovereign voice AI stack

ASR, TTS, voice cloning, and serving infrastructure — fully deployed on your cloud or on-premise, no third-party data exposure.

SIP & telephony integration

Connectors for Twilio, Plivo, Exotel, Asterisk, FreeSWITCH, and custom SIP trunks — without replacing your existing telephony infrastructure.

Campaign & recording pipeline

Inbound and outbound campaign management, call recording storage, downloadable transcripts, and structured data export to your CRM or data warehouse.

Agentic workflow layer

Voice agents connected to your SQL databases, document stores, and web search — with handoff logic to human agents or specialist AI agents.

Common questions

Before you
book the call.

The questions most teams ask us before they decide to move forward.

Ask us anything
What does "sovereign architecture" mean in practice?

Every component — ASR, TTS, voice cloning model, and LLM — runs on your infrastructure. No audio or conversation data is sent to OpenAI, Google, or any external API. This is critical for BFSI, healthcare, and government use cases with strict data residency requirements.

Can you clone a specific voice for our brand?

Yes. We use open-source voice cloning models (Coqui XTTS, F5-TTS, Kokoro) to create brand voices from a short reference recording. The cloned voice model is yours — deployed on your infrastructure, not licensed from a vendor.

Which Indian languages do you support?

We support Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, Marathi, Gujarati, Punjabi, and Odia natively, with ASR models fine-tuned for regional accents. We also support 15+ global languages including Arabic, Spanish, French, and Mandarin.

What is NextNeural and how is it different from a custom build?

NextNeural is our pre-built Voice AI platform — it ships with the full stack already assembled: voice cloning, SIP integration, campaign management, transcription, and structured data extraction. A custom build gives you more control and deeper integration. We help you decide which path fits your timeline and requirements.

Can the voice agent query our database or documents during a call?

Yes. This is a core capability. Voice agents are connected to your SQL databases, document stores, and web search tools. When a caller asks about their account balance, policy details, or product availability, the agent queries the right source in real time and responds within the latency budget.
