Voice AI Integration

We integrate your voice agent with your CRM, helpdesk, ERP, and data infrastructure so it can look up customer records, update tickets, schedule appointments, and complete transactions in real time during a call.

Voice AI for Industries

Healthcare, banking, and insurance have specific compliance requirements for customer conversations. We build voice AI agents for regulated industries with data handling, consent management, and audit trails designed to meet sector-specific standards from day one.

How We Build Voice AI Agents?

01

Real-Time Communication Infrastructure

LiveKit and Twilio establish a secure, low-latency WebRTC audio channel between the user and the AI agent handling room management, authentication, and bidirectional streaming so voice conversations flow without delays or dropouts.

02

Speech-to-Text (STT) Processing

OpenAI Whisper or Deepgram transcribe the caller's voice into text in real time accurately handling accents, background noise, and natural speech feeding clean input into the conversation layer.

03

LLM-Powered Conversation Intelligence

GPT or Claude processes the transcribed text using custom system prompts understanding intent, maintaining context across the call, and executing business logic through function calling to generate the right response.

04

Text-to-Speech (TTS) & Voice Synthesis

ElevenLabs converts the LLM's response into natural-sounding speech and streams it back to the caller in real time completing the loop with a voice that sounds human, not robotic.

What Makes Our Voice AI Development Different?

Industry-Specific Knowledge

Voice AI for a healthcare provider has fundamentally different requirements to voice AI for an e-commerce company. We build with your industry's specific conversation patterns, compliance requirements, and customer expectations in mind from day one.

Fast Deployment Without Cutting Corners

We move from conversation design to a working voice AI agent prototype in weeks. Speed matters when you are losing operational hours to manual call handling every day.

NDA and Data Security from Day One

Every voice AI engagement is covered by an NDA from the first call. Your call data, conversation logic, customer data, and the systems we build remain fully under your control and ownership throughout and after the engagement.

FAQs

A voice AI agent is an autonomous software system that understands spoken natural language, processes the intent behind what a caller says, accesses relevant business systems in real time, and responds conversationally completing transactions, answering queries, or routing the call appropriately without human operator involvement. The core technologies are automatic speech recognition (ASR), which converts speech to text; natural language understanding (NLU), which identifies intent and entities from the transcribed text; business logic and system integration, which retrieves or updates data; and text-to-speech (TTS), which delivers the response in a natural-sounding voice. Modern voice AI agents handle dynamic conversations not scripted call trees and can manage interruptions, topic changes, and ambiguous requests that rigid IVR systems cannot.

Voice AI agents are effective across a broad range of call types including inbound customer support queries, outbound appointment reminders and confirmations, lead qualification calls, payment collection and account balance enquiries, order status and tracking updates, FAQ and information requests, survey and feedback collection, and first-line triage before escalation to a human agent. The most effective voice AI deployments focus on call types with clear intent patterns, high volume, and repetitive handling requirements where consistency, speed, and 24/7 availability create the highest operational value compared to human agent handling.

A voice AI agent integrates with business systems through API connections built during the development process. During a call, the agent can query your CRM for customer records, look up order status in your fulfilment system, check appointment availability in your scheduling platform, update ticket status in your helpdesk, or process transactions in your payment system all in real time within the conversation. At Third Rock Techkno, we treat system integration as a core part of voice AI development, not an add-on. An agent that cannot access and act on your real business data delivers a fraction of the operational value of one that can.

Yes. Modern voice AI systems support multiple languages and regional dialects. At Third Rock Techkno, we build multilingual voice AI agents that communicate naturally in English, Hindi, Arabic, and other major languages with regional accent handling designed into the ASR configuration. Multilingual capability is most valuable for businesses serving customers across India, the Middle East, Southeast Asia, or global English and non-English markets. We design multilingual support into the voice AI architecture from the beginning not added as a translation layer after the fact because the NLU models and conversation flows for each language need to be built and tested independently.

Production accuracy varies significantly based on how well the voice AI is designed and tested. Intent recognition accuracy in well-built systems exceeds 90% for in-scope call types. Factors that affect accuracy include the quality of the ASR model selected for your caller demographics, how thoroughly the NLU models have been trained on real call data from your business, how well edge cases and unexpected conversation flows have been handled in the conversation design, and the quality of the integration with your business systems. At Third Rock Techkno, we test voice AI agents against hundreds of real conversation scenarios including regional accents, background noise, and off-script user behaviour before any production launch.

Compliance requirements for voice AI depend on the industry and geography. For healthcare, HIPAA compliance governs how call recordings and patient data are handled. For businesses operating in the EU or UK, GDPR applies to the processing of personal data captured during calls. For businesses in India, the DPDP Act establishes data handling requirements for customer information. At Third Rock Techkno, we build voice AI agents for regulated industries with compliance requirements designed in from the start including consent management, call recording policies, data retention controls, and audit trails. We do not retrofit compliance onto a system built without it.

A focused voice AI agent handling a single call type such as appointment scheduling or FAQ handling can be designed, built, integrated, tested, and deployed in six to ten weeks. More complex deployments handling multiple call types, deep CRM integration, multilingual support, or regulated industry compliance typically take three to five months. The timeline depends primarily on the number of call flows to be handled, the complexity of system integrations, and the thoroughness of testing required. At Third Rock Techkno we provide a clear project scope and timeline after a discovery session before development begins.

A traditional IVR system navigates callers through a fixed menu of pre-scripted options using keypad input or limited keyword recognition. If the caller does not fit the script, the system fails. A voice AI agent understands natural language callers can say what they need in their own words, in any order, at any point in the conversation. Voice AI agents are dynamic: they handle interruptions, clarify ambiguous requests, access live business data, and complete transactions in real time.
