Welcome to Deepdub

Deepdub provides a powerful Text-to-Speech API for generating natural, expressive speech with voice cloning, accent control, and real-time streaming. Whether you’re building voiceover pipelines, conversational agents, or content localization workflows, Deepdub delivers studio-quality audio at scale.

​
Key capabilities

Text-to-Speech

Generate speech from text using state-of-the-art models with fine-grained control over tempo, variance, and duration.

Voice Cloning

Clone any voice from a short audio sample. Upload voice prompts or pass a base64-encoded audio reference for instant cloning.

Accent Control

Blend accents between locales with precise ratio control — generate an American English speaker with a French accent, or any combination.

Real-time Streaming

Stream audio in real-time over HTTP or WebSocket connections for low-latency applications.
