The release includes two models: **Phonon 31m** (Apache 2.0 license, supports English) and **Phonon 40m** (CC BY-NC, supports five languages: English, French, German, Spanish, and Portuguese). Both are under **75 MB** and feature **100+ built-in voices**, with custom voice cloning via **Gradium Studio**. Phonon handles complex inputs like phone numbers and dates, and it supports devices from phones to single-board computers and browsers.\n\nThe model tops benchmarks on **intelligibility** (first in German/Spanish, top 3 across languages) and **speed** (fastest CPU streaming). Hugging Face built a new inference framework (**ptts**) for cross-device compatibility, including support for **CPU, GPU, and NPU** backends. Phonon integrates with **Hugging Face Transformers** (v5.21+) and has been downloaded **200,000+ times** in its first two weeks. The company also introduced the **Open TTS Leaderboard**, a new tool for comparing open TTS models across 23 languages.","keyPoints":["Phonon runs offline on devices like phones, laptops, and browsers with no cloud dependency","Two models released: **Phonon 31m** (English, Apache 2.0) and **Phonon 40m** (5 languages, CC BY-NC)","Tops benchmarks for intelligibility and speed, supports 100+ voices and custom cloning"],"whyItMatters":"Phonon shifts TTS from cloud-dependent to on-device, enabling privacy-focused speech synthesis without latency or connectivity costs.
