About

Phonon is an open-weight text-to-speech (TTS) model and inference runtime for developers adding speech generation to applications that need local, offline audio. It converts text into spoken audio and can stream speech as it is generated. The runtime provides Rust and Python interfaces, a Swift package for iOS and macOS, JavaScript for browsers, and Android libraries; it can also run as a self-hosted server with an OpenAI-compatible API. Depending on the model variant, it supports English, French, German, Spanish, and Portuguese. Phonon is intended for developers integrating speech into mobile, desktop, web, embedded, and server applications, including offline or privacy-sensitive use cases. The 31-million-parameter English model weights use the Apache 2.0 license; 40-million-parameter language-specific and multilingual weights use CC BY-NC 4.0. The runtime code is separately available under Apache 2.0 or MIT.

About

​PouchDB is an open source JavaScript database inspired by Apache CouchDB, designed to run efficiently within the browser. It enables applications to store data locally while offline and synchronize it with CouchDB and compatible servers when back online, ensuring user data remains in sync across sessions. PouchDB supports cross-browser functionality, is lightweight, requires just a script tag and 46KB (gzipped) in the browser, and can be installed via npm. It is easy to learn, requiring some programming knowledge, and is fully open source, with development conducted openly on GitHub. PouchDB allows developers to build applications that function seamlessly offline and online, providing a consistent user experience regardless of network connectivity. It offers a simple API for creating, reading, updating, and deleting documents.
