Vietnamese text to speech across all six tones
Vietnamese is a tonal language with six distinct tones, spoken by around 85 million people, mostly in Vietnam. It’s written in Quốc ngữ, a Latin-based script — which looks approachable until you notice how much work the diacritics are doing. Those marks encode both vowel quality and tone at the same time, and a single missing or misread one turns one word into another. For text to speech, precise handling of every diacritic isn’t a nicety; it’s the entire task.
Notevibes generates Vietnamese in the vi-VN locale with neural voices that distinguish all six tones and read the full diacritic set correctly, across the country’s main regional accents.
Where every mark counts
Vietnamese diacritics pull double duty. Some — ă, â, ê, ô, ơ, ư — mark which vowel you mean, while the tone marks stacked on top (à, á, ả, ã, ạ) mark how to pitch it. Because most morphemes are a single syllable, there’s little surrounding context to fall back on, so the marks themselves carry the meaning. Reading “ma”, “má”, “mà”, “mả”, “mã”, and “mạ” as six different words is exactly the kind of distinction a Vietnamese engine has to make every syllable.
Three regions, three tone systems
Accent in Vietnamese is largely a matter of how the tones are realised. The Northern (Hanoi) accent is the prestige standard used in media and education and keeps all six tones cleanly separated. The Central (Hue) accent has its own tonal mergers and regional vocabulary, giving it a distinctive sound. The Southern (Ho Chi Minh City) accent merges some tones — distinguishing five in practice — and carries a relaxed, modern rhythm that suits a lot of contemporary content.
A fast-growing digital market
As Vietnam becomes one of Southeast Asia’s most active digital markets, demand for natural Vietnamese speech is rising across e-learning, app and product localisation, video voiceover, and phone systems. Plain-words direction and a persona line keep long narration lively, and MP3 or WAV export with a commercial license makes the output ready for release.
