SeloraX Voice AI
Bangla AI call agent, grown into a multi-tenant platform merchants run themselves.
A working AI agent that answers and places calls in fluent Bangla end-to-end, now running as a multi-tenant product: merchants onboard themselves, buy a plan, and manage their own agents and recordings across 11 console pages. (Shown as an architecture narrative, client system, no code or data exposed.)
A voice-AI call agent for Bengali-speaking merchants: an AI that holds real phone conversations in Bangla over a SIP gateway. Built the voice engine first, then the platform around it. Each merchant is an isolated tenant with a self-serve console for agents, campaigns, and call recordings, reached through a public merchant API and a front door with real pricing. An entitlement gate ties a plan to what a tenant may actually run, inbound calls route by DID, and per-call cost is recorded against the call that caused it so the economics stay legible.
This is a client system, shown as an architecture narrative only: no source code, credentials, or user data are exposed.
Problem
Bengali merchants needed an automated phone agent, but off-the-shelf voice AI has no usable real-time Bangla speech, latency and pronunciation both break the illusion of a real call.
Constraint
A phone call tolerates only a few hundred milliseconds of round-trip lag before it feels broken, and the voice had to sound natural in Bangla, not machine-read.
Decision
Bridged a SIP telephony gateway into a realtime LiveKit audio pipeline feeding Gemini Live, and paired it with a custom-trained Bangla TTS voice tuned for phone-band audio.
Tradeoff
A custom TTS voice is far more work than a hosted one and has to be maintained, but no hosted option produced acceptable conversational Bangla.
Result
A working AI agent that answers and places calls in fluent Bangla end-to-end, now running as a multi-tenant product: merchants onboard themselves, buy a plan, and manage their own agents and recordings across 11 console pages.
