IndicF5 is a text-to-speech model for developers and researchers who need to generate spoken audio in Indian languages. It supports Assamese, Bengali, Gujarati, Hindi, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil and Telugu.

llama.rn is a library for developers adding local LLM features to React Native apps on iOS and Android. It brings llama.cpp inference onto the device, so an app can process model requests on the user's hardware.

Offline Translator is an Android app for translating material when you don't have an internet connection or want translation to stay on your device. It handles everyday text as well as images and PDF/ODT documents.

TTS WebUI is a self-hosted browser interface for people creating speech and music or processing audio with AI models. It brings these tasks into one place, with model choices for different kinds of audio work.

PaddleSpeech is a speech and audio toolkit for developers and researchers building applications on their own machines or servers. Built on PaddlePaddle, it supports pretrained models alongside training and evaluation workflows.

Seamless Communication is Meta's family of AI models for developers and researchers building multilingual speech applications. It covers translation and transcription, with dedicated models for conversations and expressive speech.

Kokoro-FastAPI generates speech on your own machine or server using Kokoro-82M. It's for developers adding narration to reading apps, audiobooks or voice assistants through an OpenAI-compatible speech API.

Voicebox combines speech creation and dictation for people producing audio or working with AI agents. It's a free, open-source alternative to ElevenLabs and WisprFlow that processes voice data on your own machine.

Abogen turns books, documents and subtitle files into narrated audio for readers making audiobooks and creators producing voiceovers. It can generate matching captions or follow timestamps for timed narration.

RealtimeTTS is a Python text-to-speech library for developers building voice assistants and other apps that need spoken responses before the full text is ready. It accepts both complete text and incoming LLM output.

Vocaldi is a paid Mac app that combines voice typing with read-aloud for people who prefer speaking to typing or listening to written text. Transcription, dictation cleanup and speech synthesis run on your Mac, so the audio and text you process stay on the device. It requires Apple Silicon and macOS 14 or later.

Sandbook is an offline text-to-speech reader for iPhone and iPad, for people who want to listen to books and documents without uploading them. It runs Kokoro-82M on the device through Apple MLX, with the speech model and voices included in the app. It needs no account and has no ads or tracking.

MLX Omni Server lets developers use local models through both OpenAI-compatible and Anthropic-compatible APIs on an Apple Silicon Mac. It's for applications built around those SDKs that need inference on hardware the developer controls. Apple's MLX framework provides hardware acceleration, and all AI processing stays on the Mac.

Subtitle Edit is an offline desktop application for people creating captions or revising subtitle files alongside video. Editing, format conversion and playback run on your computer. Optional translation and speech services send requests to external providers.

IndexTTS is a local text-to-speech system for people creating spoken audio and developers adding speech generation to applications. It can reproduce a voice from a single reference recording.

MOSS TTS generates speech for developers and creators working on narration, dubbing and other long audio content. It supports consistent voices across long passages and can clone a speaker from reference audio without separate training for that voice.
