Vietnamese is the official language of Vietnam, a country of over 100 million people and one of Southeast Asia's fastest-growing economies. Local messaging app Zalo counts 79.6 million monthly users, a sign of how much daily life runs online in Vietnamese.
Supporting Vietnamese lets you serve customers from Hanoi to Ho Chi Minh City and reach a diaspora of about 5 million, including 2.3 million Vietnamese Americans, 72% of whom speak Vietnamese at home.
People rarely stick to one language. Gladia follows Vietnamese speakers when they switch mid-sentence, so your transcripts stay clean.
Code-switchingUse cases
Whatever you're building, Vietnamese shouldn't be the thing that slows it down.
Vietnam's IT outsourcing sector has grown 20 to 30% a year, so Vietnamese engineering teams run internal standups in Vietnamese between client calls in English.
Meeting assistants →Most Vietnamese immigrants in the US speak English less than very well, so banks, insurers, and clinics in California and Texas field Vietnamese calls daily.
CCaaS →Northern Vietnamese has six tones, so a voice agent that misses one can turn ma into six different words, from ghost to mother.
Voice agents →Make Vietnamese podcasts, videos, and broadcasts searchable and subtitled, and reach audiences in other languages through translation.
Media →Supported languages
Being multilingual has been our priority since day one. Gladia supports 100 languages, with code-switching and automatic language detection integrated into all models by default.
Ship Vietnamese voice features with an API built for messy, real-world conversations.
