XTTS v2 generates speech from text on your own hardware, using a voice recording as a reference. It's for developers adding speech to applications and researchers adapting a speech model to their own data.

StyleTTS 2 is a text-to-speech model for developers and speech researchers who want to generate expressive speech on their own hardware. It can choose a speaking style from the text without a reference recording.

NeuTTS is a collection of on-device text-to-speech models for developers building voice assistants and speech-enabled apps. It generates audio on your own hardware rather than sending speech generation to a cloud API.

MLX Audio is a Python library for developers building speech and audio applications on Apple Silicon Macs. It runs models locally using Apple's MLX framework, with support for generated speech, transcription and audio processing.

Voci is a local text-to-speech reader for Windows 10 and 11 that speaks in voices cloned from short audio recordings. It's for people who want to listen to documents or pasted text in a chosen voice without sending the content to a cloud service. After the initial downloads, it works offline and doesn't require an account or API key.

Qwen3-TTS is a family of local text-to-speech models for developers building speech applications or creating audio with custom voices.

Fish Diffusion is a Python framework for developers and researchers training diffusion models for text-to-speech, singing voice synthesis and singing voice conversion. It works with your own datasets and provides code you can adapt for different voice generation tasks.

Willow Inference Server is a self-hosted speech server for developers building voice assistants, transcription apps, and accessible interfaces. It handles speech recognition and speech generation on your own hardware.

Izwi is a local voice AI app and runtime for people and teams processing speech on their own hardware or inside infrastructure they control. It brings audio tools and voice conversations into a desktop app, browser interface, CLI and inference server.

VoxCPM is a local text-to-speech system for developers and audio creators who want to generate speech with voices they can design or clone. It supports multilingual narration and control over how a voice delivers the text.

GPT-SoVITS is a local voice cloning and text-to-speech tool for people creating speech in a custom voice. Its web interface covers speech generation, voice training and preparation of audio datasets.

Alexandria Audiobook turns books into audio with separate narrator and character voices. It's for people who want to choose the cast and correct individual passages before exporting an audiobook.

KittenTTS is a Python text-to-speech library for developers adding local speech generation to apps or producing spoken audio from text. It supports voice cloning without model training and doesn't require a GPU.

OpenVoice generates speech in a reference speaker's voice from a short audio clip. It's for developers and creators who need the same voice across languages or want to vary its delivery without changing the speaker.

Voice-Pro is a locally run speech processing and dubbing app for creators working with recordings or multilingual video. Its Gradio browser interface brings audio preparation, transcription and speech generation into one workspace. Internet access is required.

F5-TTS is a local text-to-speech system for developers and creators generating speech on their own hardware. Its Gradio app provides a browser interface for speech generation, with tools for training and fine-tuning models.
