Sarvam text to speech converts books into natural audiobooks in 11 Indian languages. A full-length novel costs under Rs 1,000 to produce. India publishes 90,000+ books a year, and fewer than 1% become audiobooks. Sarvam changes that.

Traditional recording requires 40+ studio hours, professional editing, and QA for a single 5-hour audiobook. For a regional publisher selling 500 to 2,000 copies, the production cost exceeds revenue. Sarvam AI narration drops the cost to under Rs 1,000, making every book in the catalog viable.
Audio platforms have millions of listeners but limited regional catalogs. Scaling from 500 Hindi titles to 5,000 across 11 languages through traditional recording would take years. Sarvam lets platforms batch-generate, QA, and publish their entire catalog in weeks.
Demand for regional audiobooks is real and growing. Audiences search for Telugu, Bengali, and Tamil audiobooks that do not exist yet. Sarvam supports 11 Indian languages, so publishers can meet this demand today.
Prepare your manuscript
Clean up the text. Split into chapters. Mark dialogue vs narration if you want character voices. A 200-page novel is roughly 50,000 words or 300,000 characters.
Assign voices per character
Pick a narrator voice for the main narration. Assign different voices to major characters if the book has dialogue. Adjust emotion, pitch, and pace per scene: slower for emotional moments, normal for exposition, slightly faster for action sequences.
Generate chapter by chapter
Process each chapter separately via the API. This gives you control over voice consistency, pacing variation, and quality checking. A full 200-page novel generates in 2-3 hours. Listen to each chapter, regenerate any sections that need adjustment.
Package and distribute
Stitch chapters into the final audiobook. Convert to M4B (standard audiobook format) or MP3. Add chapter markers and metadata. Distribute on audiobook platforms, Google Play Books, Spotify, or your own platform.

India's audio content market centers on music and audio stories. Full-length narrated audiobooks remain a tiny niche. Audiences actively search for regional audiobooks that barely exist. The first platforms and publishers to fill this gap with quality regional language audiobooks will define the category.
The global audiobook market is valued at over $7 billion and growing at 25% annually. India remains a small fraction of that figure, despite having one of the largest reading populations in the world. The bottleneck has always been production cost. AI narration removes that bottleneck, making it possible for a regional publisher to convert an entire catalog by next quarter.
