Common Questions Answered

Everything you need to know before starting an AI project with XPndAI.

What is voice AI and what does XPndAI build?

Voice AI is AI that can hold natural phone or in-app conversations in real time. XPndAI builds inbound and outbound voice AI agents for lead qualification, customer support, appointment booking, collections, and IVR replacement — running 24/7 without human agents, in English, Hindi, and 10+ Indian languages.

How much does voice AI development cost in India?

Voice AI projects at XPndAI start from ₹8–15L for a focused inbound or outbound voice agent MVP, ₹25–60L for a full voice AI call centre replacement, and ₹75L–2Cr for enterprise multi-language voice AI at scale. Fixed-fee pricing.

Which languages does XPndAI voice AI support?

XPndAI voice AI supports English, Hindi, Tamil, Telugu, Kannada, Bengali, Marathi, Gujarati, Malayalam, Punjabi, Odia, and Arabic. Agents can switch languages mid-conversation and handle code-mixed speech (Hinglish, Tanglish). We use Vapi, Retell AI, and custom speech pipelines.

How long does it take to build a voice AI agent?

A focused voice AI agent (single use case — inbound lead qualification or appointment booking) takes 3–5 weeks to build and deploy. A multi-scenario voice AI system with CRM integration takes 8–12 weeks. XPndAI does a live demo call with your team in Week 1.

Can voice AI replace human call centre agents?

Voice AI is best for high-volume, structured conversations — qualification calls, appointment reminders, order status, collections follow-up, and FAQ handling. XPndAI voice agents handle 80–90% of calls without human intervention. Complex complaints and edge cases route to human agents automatically.
