Generative AI Audiobook Platform

An AI application that transforms manuscripts into human-like narrated audiobooks using modern generative voice technology.

PythonLLMsTTSAudio ProcessingQueue Workers
Overview

A production pipeline that parses a manuscript, identifies speakers, assigns distinct voices and renders a full multi-character audiobook through an automated, resumable workflow.

Problem

Audiobook production is expensive and slow. Generative voice makes it feasible, but only with an engineering pipeline around it that handles long-form text, consistency and failure recovery.

Impact
  • Manuscript-to-audiobook production without a studio pipeline
  • Multi-character narration from a single source document

Engineering Decisions

Chapter-level job graph

Work is decomposed into resumable units so a single failed segment never restarts the whole book.

Consistent voice mapping

Detected characters are pinned to voices for the entire manuscript to preserve narrative continuity.

Author-in-the-loop review

Authors can re-render individual segments rather than accepting whole-book output.

Challenges & Solutions

Dialogue attribution

Ambiguous speaker attribution is resolved with contextual analysis and reviewable defaults.

Long-form throughput

Queue-based workers parallelize synthesis while preserving output ordering.

Key Learnings
  • Long-running AI workloads need job graphs, not scripts
  • Consistency is the difference between demo and product
