ElevenLabs is bought for voicing videos, auto-replies and voice messages. Open speech models install on your own server: scripts and voice recordings are never handed over, you can synthesize without limits, and some models run on an ordinary CPU with no GPU at all. Several of them clone a voice from a short sample, so you can keep one consistent brand voice instead of re-recording every time a line changes. The weak spots are familiar: intonation flattens out on long or emotional copy, stress in names and technical terms often needs manual correction, and live dialogue requires real tuning. And one issue is legal rather than technical: another person's voice must not be cloned without their written consent.
Speech synthesis in 10 languages, including Russian: voice cloning from 3 seconds, ready-made voices and creating a voice from a text description.
Speech synthesis with voice cloning and adjustable expressiveness. The multilingual version supports 23 languages, including Russian; Turbo and Flash are sped up for live dialogue.
Speech synthesis with voice cloning and fine control over emotion, speed and pitch.
Speech synthesis with voice cloning and natural intonation. VoxCPM2 supports 30 languages, including Russian.
Lightweight Russian speech synthesis that runs on a regular CPU. Version v5 added CIS languages and languages of Russia's peoples: Tatar, Bashkir, Yakut, Kazakh and others.
Very fast speech synthesis that runs even on a Raspberry Pi. Ready-made voices in 35+ languages, including several Russian ones.
Qwen3-TTS, Chatterbox, Zonos and VoxCPM are listed as commercially usable, while Silero's main models are non-commercial CC BY-NC and Piper's terms depend on the individual voice. The popular XTTS and Fish Speech are non-commercial too, and cloning a real person's voice requires their consent.
An open model can run on your own server: data stays in-house, there is no per-request fee, and the model can be fine-tuned on your documents.
