With 85+ million speakers worldwide, Vietnamese is one of the most widely spoken languages — and Hapi supports it with fully local, private transcription on your Mac.

Six tones, complex diacritical marks, and monosyllabic word structure make Vietnamese speech recognition demanding.

How Vietnamese Speech Recognition Works

Modern speech recognition for Vietnamese uses transformer-based AI models trained on thousands of hours of Vietnamese audio. Hapi runs these models directly on your Mac's Apple Silicon chip, so your Vietnamese audio never leaves your device.

The transcription engine automatically detects Vietnamese and applies language-specific processing including punctuation, capitalization, and special character handling.

How to Transcribe Vietnamese Audio on Mac

1. Download Hapi — it's free and installs in under a minute
2. Press the hotkey (customizable) to start recording
3. Speak in Vietnamese — the language is detected automatically
4. Release the hotkey — your transcription is auto-pasted wherever your cursor is

That's it. No configuration, no cloud accounts, no language selection menus. Hapi detects Vietnamese automatically and transcribes locally on your Mac.

Vietnamese Transcription Accuracy Tips

• Pronounce tones clearly for best accuracy
• All Vietnamese diacritics are supported in output
• Speak at a natural pace

For the best results, use a dedicated microphone rather than your Mac's built-in mic, especially in noisy environments.
