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.

Kokoro is a text-to-speech model and inference library for developers adding speech generation to personal projects or production applications. It runs on your own hardware and uses the compact Kokoro-82M model.

SurfSense is a desktop NotebookLM alternative for people working with confidential documents, research or study material. It answers questions across your files and turns selected sources into editable outputs.

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.

Lingolay is a free, open source screen translator for people who want translated subtitles while playing games or watching videos. It reads visible text with OCR, translates it on your computer and displays the result in a floating overlay. Optional Piper voices read the translations aloud.

SillyTavern is a locally installed interface for AI hobbyists who want control over prompts and access to text, image and voice models in one place. It's an independently developed fork of TavernAI and connects to a separate model backend or API provider.

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.

Amuse is a Windows app for people who want to generate media and text with models running on their own hardware. It combines generation with editing tools for both generated output and existing local video.

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.

sherpa-onnx is a toolkit for developers building speech features that work offline on their own devices. It covers transcription, speech generation and audio analysis, with processing kept local.
