Description

Phonon serves as an open-weight text-to-speech (TTS) model and inference runtime designed for developers seeking to incorporate speech generation into applications that require local and offline audio capabilities. This innovative system transforms text into spoken audio and has the ability to stream speech in real-time as it is produced. The runtime offers interfaces for Rust and Python, a Swift package for iOS and macOS, JavaScript support for web browsers, and libraries for Android; it can also function as a self-hosted server compatible with OpenAI's API. Depending on the variant of the model used, it accommodates languages such as English, French, German, Spanish, and Portuguese. Phonon is tailored for developers aiming to integrate speech functionalities into mobile, desktop, web, embedded, and server applications, particularly in scenarios requiring offline access or enhanced privacy. The English model, which consists of 31 million parameters, is licensed under Apache 2.0, while the language-specific and multilingual models, featuring 40 million parameters, operate under CC BY-NC 4.0. Additionally, the runtime’s code is available under either the Apache 2.0 or MIT licenses, making it accessible for various development needs. This flexibility and wide-ranging support make Phonon a versatile choice for speech synthesis across different platforms.

Description

gTTS, which stands for Google Text-to-Speech, is a Python library and command-line interface tool that allows users to interact with the text-to-speech API provided by Google Translate. This tool enables users to write spoken audio data in mp3 format to various outputs, such as a file, a bytestring for additional audio processing, or even directly to stdout. Additionally, it offers the option to pre-generate URLs for Google Translate TTS requests, which can be utilized by other external applications. The library features a customizable tokenizer specifically designed for speech, allowing for arbitrary lengths of text to be processed while maintaining correct intonation, handling of abbreviations, decimal numbers, and more. Furthermore, it includes customizable text preprocessing capabilities that can address pronunciation issues, enhancing the overall quality of the speech output. With these diverse functionalities, gTTS serves as a versatile tool for generating high-quality spoken audio from text.
