Multilingual voice AI for calls and support
Trusted by 100+ innovative teams
What we build
Unlike traditional IVR systems that force callers through rigid menus, voice agents use large language models to understand intent, handle interruptions, and speak naturally. They operate 24/7, handle thousands of concurrent calls, and cost a fraction of human agents — typically Rs 1-2 per conversation versus Rs 50-100 for a human agent. Boolean & Beyond builds custom voice agents with multilingual support for Indian languages, integrated with your CRM, calendar, and business systems.

Deep dive
AI voice agents replace traditional IVR systems with natural conversation. Callers speak normally — no "press 1 for billing" — and the agent understands intent, pulls relevant data from your systems, and resolves requests in real time. Our voice agents handle 500+ concurrent calls with sub-second response times.
We build voice agents for customer service, appointment booking, order tracking, outbound collections, and survey calls — across English, Hindi, Tamil, Kannada, and 10+ Indian languages.
The pipeline has four stages: Speech-to-text (Whisper/Deepgram) converts caller audio to text in real-time. The LLM (Claude/GPT-4) processes the request, reasons about the right response, and decides which tools to call. Tool execution queries your CRM, booking system, or database for real data. Text-to-speech (ElevenLabs/Azure Neural TTS) converts the response to natural-sounding voice.
End-to-end latency is under 500ms — fast enough that conversations feel natural, not robotic. We optimize each stage: streaming STT, prompt caching for the LLM, pre-fetched common responses, and chunked TTS synthesis.
Inbound Support: Replace your IVR with AI that understands natural language. Handle account inquiries, billing questions, order status, and troubleshooting without hold queues. Escalate complex issues to human agents with full conversation context.
Appointment Booking: Restaurants, clinics, salons, and service businesses. The agent checks availability, books slots, sends confirmations, and handles rescheduling — all by phone.
Outbound Campaigns: Payment reminders that negotiate installment plans. Appointment confirmations with rescheduling options. NPS surveys that adapt follow-up questions based on sentiment. Lead qualification calls that route hot leads to your sales team.
India requires multilingual voice AI. Our agents detect the caller's language automatically and switch seamlessly. We handle code-switching (Hindi-English mix), regional accents, and colloquial expressions. Fine-tuned Whisper models for Indian English achieve 95%+ accuracy vs 85% for generic models.
Every call generates structured data: intent classification, sentiment score, action items, and full transcript. Integrate with your CRM, ticketing system, and analytics platform. Dashboards show call volume, resolution rate, average handle time, and customer satisfaction.
Voice agent projects start at ₹15 lakhs for a single-use-case deployment (e.g., appointment booking). Enterprise multi-channel deployments range from ₹30-60 lakhs. Per-call costs (telephony + AI) average ₹2-5 per minute depending on complexity and model tier.

Fintech: Automated compliance checking, fraud detection pipelines, and intelligent document processing for KYC/AML workflows. We build systems that process thousands of applications daily with 95%+ accuracy.
Healthcare: Clinical decision support, patient communication automation, and medical record analysis. HIPAA and DPDP Act compliant architectures with proper audit trails.
E-Commerce: Personalized recommendation engines, semantic product search, dynamic pricing algorithms, and conversational shopping assistants that increase conversion by 20-35%.
Manufacturing: Computer vision quality inspection, predictive maintenance models, and production scheduling optimization. Edge deployment for real-time factory floor decisions.
Fixed-scope projects: Clear deliverables, timeline, and investment. Ideal for well-defined features or MVPs. You know exactly what you get and what it costs before we start.
Dedicated team: 2-6 engineers embedded in your workflow for ongoing development. Sprint-based delivery with weekly demos. Scale up or down based on your roadmap.
Technical advisory: Architecture review, technology selection guidance, and hands-on mentoring for your team. Ideal when you have developers but need senior technical direction.
How long does a typical project take? MVPs in 6-8 weeks, production features in 8-12 weeks, enterprise platforms in 3-6 months. We use 2-week sprints with weekly demos so you see progress continuously.
What does it cost? Projects range from ₹10 lakhs for focused integrations to ₹50+ lakhs for full platform builds. We provide detailed estimates after the discovery sprint — no surprises.
Do you support post-launch? Yes. Most clients transition to a maintenance retainer (₹2-5 lakhs/month) for ongoing optimization, bug fixes, and feature additions. We don't build and disappear.
An AI voice agent POC typically costs Rs 5-10 lakhs and takes 3-4 weeks. A production-ready multilingual voice agent with CRM integration costs Rs 15-40 lakhs depending on complexity. Ongoing costs are Rs 1-2 per conversation versus Rs 50-100 for human agents — a 95%+ cost reduction per interaction.
Yes. Modern voice AI models from Sarvam AI, Bhashini, and custom fine-tuned models support Hindi, Tamil, Kannada, Telugu, Malayalam, Bengali, Marathi, and Gujarati with near-native fluency. We build voice agents that can switch languages mid-conversation based on caller preference.
Traditional IVR forces callers through numbered menus ('Press 1 for billing'). AI voice agents understand natural speech — callers just say what they need. Voice agents handle complex multi-turn conversations, remember context, access your systems in real-time, and can complete transactions like booking appointments or processing refunds without human intervention.
AI voice agents can handle thousands of concurrent calls simultaneously — there is no queue. Each caller gets immediate attention. This eliminates hold times entirely. For comparison, a 50-seat call centre handles roughly 50 concurrent calls; a voice agent system handles 5,000+ with the same infrastructure cost.
