Open-source alternatives emerge for ElevenLabs text-to-speech

Several open-source and free alternatives to the ElevenLabs AI voice generator are gaining traction, offering users more control and lower costs.

Fish Audio S2 Pro is noted for its high quality and expressive emotion control, supporting over 80 languages. Other specialized models include Chatterbox for free commercial use, Kokoro for lightweight CPU-friendly tasks, Tortoise TTS for hyper-realistic results, and Piper for low-power devices like Raspberry Pi.

VoiceStudio provides a comprehensive local solution for voice cloning, video dubbing, and text-to-speech. Unlike cloud-based services, VoiceStudio processes data directly on the user's computer, enhancing privacy and eliminating monthly fees. It supports 646 languages and utilizes NVIDIA CUDA acceleration on Windows and Linux, or Apple Silicon's Metal on macOS. While it can run on a CPU, dedicated hardware is recommended for optimal performance.
