NVIDIA released Magpie TTS Multilingual, a 364M-parameter open-weights text-to-speech model supporting 12 languages including newly added Modern Standard Arabic, Korean, and Brazilian Portuguese. It's designed for cascaded voice agent architectures where ASR, LLM, and TTS run as independently tunable components on infrastructure you control, deployable via NVIDIA NIM.

Why: If you're building voice agents and currently relying on a single integrated speech API, this gives you an open-weights TTS you can self-host for data residency and latency tuning — but the 12 supported languages don't include Malay, Mandarin, or Tamil, so check the language list before committing. The cascaded architecture pitch matters: swapping individual components (ASR, LLM, TTS) independently is a real advantage over monolithic speech models when you need domain-specific tuning.
