Transcribe Vietnamese audio with WhisperAI
WhisperAI transcribes Vietnamese (Tiếng Việt) audio for the around 85 million speakers who use the language across Vietnam, with significant diaspora in the US, France, Australia and Canada. Built on OpenAI Whisper and tuned for the realities of Vietnamese speech, the service produces publication-grade transcripts in Latin-based Vietnamese alphabet with extensive diacritics for tone and vowel quality.
Six tones and a diacritic load that breaks generic ASR
Vietnamese is tonal — six tones in the northern dialect, five in the south — and tones are written as diacritics on vowels. Get the tone wrong and you've written a different word. Whisper handles Vietnamese tone marks correctly and distinguishes Hanoi from Saigon dialect, which is essential because the tone systems differ.
Northern (Hanoi), Central (Huế) and Southern (HCMC) Vietnamese are all supported, with full tone-mark preservation.
