Building Production TTS at Scale: Lessons from Real-World Voice API Development

Deploying text-to-speech in production reveals hidden complexities that prototypes never surface—character limits, scaling costs, and distributed concurrency challenges that require careful architectural decisions. This technical deep-dive through multiple TTS providers exposes the cost-quality tradeoffs and engineering patterns essential for voice AI backends operating at scale. Developers building TTS-powered applications will find practical solutions to problems they'll inevitably encounter in production environments.
