Deep Voice 3 vs ElevenLabs

Deep Voice 3 is an open-source PyTorch implementation of the Deep Voice 3 text-to-speech model from Baidu Research. It reproduces convolutional sequence learning for scalable neural TTS and ships pretrained checkpoints with audio demos for single-speaker and multi-speaker setups.

The project includes models trained on LJSpeech for single-speaker synthesis and on VCTK for 108-speaker multi-speaker generation. The demo page hosts sample audio clips, attention plots, and links to pretrained weights on GitHub.

It is aimed at researchers and developers who want a reference implementation of Deep Voice 3 rather than a hosted speech API. Training scripts, inference code, and community contributions live in the public GitHub repository.

ElevenLabs turns text into lifelike speech and runs voice agents through three product lines: ElevenCreative for content, ElevenAgents for customer experience, and ElevenAPI for developers. The platform lists 5,000 plus voices across 70 plus languages, plus speech-to-text, voice cloning, dubbing, music, sound effects, and a Speech Engine SDK that handles turn-taking over WebSocket while your server supplies the LLM.

Legacy TTS APIs sound robotic and bolt STT on as an afterthought. ElevenLabs bundles narration, ads, character voices, dubbing studio workflows, and low-latency business tiers in one credit wallet shared across products. Business plans advertise TTS as low as 5 cents per minute and Pro unlocks 44.1 kHz PCM plus 192 kbps output, which matters when you are shipping audiobooks or IVR at scale rather than prototyping a single clip.

Creators, game studios, and enterprise CX teams pick ElevenLabs when they need commercial licensing, professional voice clones, and API concurrency. Free users get 10,000 monthly credits to test, while Scale and Business add workspace seats, team collaboration, and millions of credits for production workloads.
