Building a 142-language TTS engine for LuxurAI: Architecture & challenges

What We Built Today

We shipped LuxurAI TTS, an in-house text-to-speech engine supporting 142 languages and 322 voices, including 10 dedicated Indian voices. This integrates into our modular block UI synthesis engine for voice-guided workflows.

The Problem We Solved

Most AI TTS services prioritize English/European languages. For a global tool like LuxurAI, we needed native support for Indian languages from day one.

How The Architecture Works

  • Multi-voice pipeline: Parallel model routing for low-latency synthesis.
  • Hybrid orchestration: Combines our in-house Neo v0.1 model with external APIs for broad coverage.
  • Dynamic load balancing: Auto-scales based on concurrent voice requests.

Transparent Economics

  • ₹0.25 per credit (25 paise)
  • Zero subscriptions, pure pay-as-you-go

How We Can Make This Better

We'd love feedback from linguists or devs familiar with:

  • Regional pronunciation edge cases
  • Real-time streaming optimizations
