Description

NVIDIA's Parakeet-RNNT-1.1B is an advanced multilingual automatic speech recognition system designed to deliver high-quality transcriptions for various voice applications. Comprising 1.1 billion parameters and having been trained on over 90,000 hours of audio data, it accommodates 25 different languages along with their regional dialects, such as English, Spanish, French, German, Italian, Arabic, Japanese, Korean, Portuguese, Russian, Hindi, Dutch, Danish, Norwegian, Czech, Polish, Swedish, Thai, Turkish, and Hebrew. This innovative model possesses the capability to automatically identify the spoken language and employs a universal tokenizer that integrates language-specific tokenizers into a unified vocabulary for enhanced cross-lingual learning and deployment. Furthermore, Parakeet-RNNT generates transcripts that are case-sensitive, featuring both uppercase and lowercase letters, punctuation, spaces, and apostrophes, thus ensuring that the output meets the rigorous standards required for production-level voice applications and effective downstream language comprehension. Its versatility and robust performance make it a valuable tool in the realm of speech recognition technology.

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.
