Top matches by setup
Computed with the same deterministic matcher as the homepage, restricted to models whose official source lists Portuguese. To keep the shortlist useful, each row shows the best-ranked model from three different families (for example, only one Whisper size). Scores are decision guidance, not accuracy claims.

Choose by requirement
- Live captions and voice input
- Native streaming: Nemotron 3.5 ASR Streaming 0.6B, VibeVoice-ASR Streaming 1.5B, Voxtral Mini 4B Realtime 2602 and VibeVoice-ASR-Streaming-7B. Everything else needs a chunking runtime, which adds latency.
- Speaker-labelled meetings
- Native diarization: VibeVoice-ASR 7B, VibeVoice-ASR Streaming 1.5B and VibeVoice-ASR-Streaming-7B. Other models need a separate diarization pipeline.
- Commercial products
- Permissive licenses: Whisper (tiny, base, small, medium, turbo), Qwen3-ASR 0.6B, Qwen3-ASR 1.7B, Omnilingual ASR CTC 300M, Cohere Transcribe 03-2026, VibeVoice-ASR 7B, VibeVoice-ASR Streaming 1.5B, VibeVoice-ASR-BitNet, Fun-ASR-MLT-Nano-2512, Voxtral Mini 4B Realtime 2602, Granite Speech 5.0 2B, Granite Speech 5.0 470M TurboCTC and VibeVoice-ASR-Streaming-7B. 4 other models carry attribution, ShareAlike or custom terms.

Multilingual models that do not list Portuguese
Whistle and Jais-ASR are multilingual but do not list Portuguese in the reviewed official source, so the matcher does not recommend them for this language.
Common questions
What is the best local speech-to-text model for Portuguese?
There is no single winner; it depends on the workload. In the matcher, Whisper turbo leads for long recordings on a mid-range GPU, VibeVoice-ASR 7B for meetings with speaker labels and VibeVoice-ASR-BitNet for CPU-only machines. Benchmark the top two or three on your own Portuguese audio before deciding.
Is there an offline Portuguese model with real-time streaming?
Yes. Nemotron 3.5 ASR Streaming 0.6B, VibeVoice-ASR Streaming 1.5B, Voxtral Mini 4B Realtime 2602 and VibeVoice-ASR-Streaming-7B list Portuguese and have a native streaming architecture. Measure end-to-end latency on your hardware.
Does Whisper support Portuguese?
Yes. All Whisper sizes list Portuguese in the official tokenizer language list. Smaller sizes trade accuracy for speed; Whisper turbo is the usual starting point on a GPU.
Which models do not support Portuguese?
Among multilingual models, Whistle and Jais-ASR do not list Portuguese in their reviewed sources. English-only models are also excluded.
