Voice AI use cases for businesses in Vietnam
A voice AI agent answers your phone in Vietnamese, English or Mandarin, books, takes messages and hands calls to a person. These eight Vietnam use cases are the calls hotels, clinics, factories and schools most often miss, with the local rules for outbound calls and a plain note on what it does not cover (Zalo).
Eight use cases
How businesses in Vietnam use voice ai.
Fictional businesses in real places, to show what the agent does with calls.

- Opens by saying who is calling, why, and that the call can stop.

- Adds anyone who says stop to your do-not-contact list.
Visitors who asked for a call are reached while they are still planning, inside hours you chose.
In practice
How voice ai is used in Vietnam.
- Voice agents speak Vietnamese, English and Mandarin. We claim the language, not a northern, central or southern accent.
- International workspaces import a number from Twilio, Telnyx or Plivo. We do not sell +84 numbers and have not verified which Vietnamese numbers those providers can hold; forwarding your line is the simplest start.
- Transfer to a person and voicemail detection work on Plivo and Telnyx numbers, not on an imported Twilio number.
- We found no reliable national figure for phone-answering habits, so judge the need from your own missed-call log.
Plainly
What this will not do for you in Vietnam.
So you can rule it in or out before you start.
- No Zalo: we do not integrate with Zalo, so it cannot answer Zalo messages or calls.
- Mandarin is voice-only: WhatsApp and chat replies cover Vietnamese and English, not Mandarin.
- It does not check the national do-not-advertise list or store proof of consent; both are yours to do.
- It does not give medical advice or negotiate custom itineraries. Tell it which calls go to a person.
The rules
The rules that apply in Vietnam.
The rules differ by country and change; you are responsible for following them where you operate.
Advertising calls: Decree 91/2020 as reported
Vietnamese legal press and law-firm pages read on 25 October 2026 (not the official text) report that Decree 91/2020/ND-CP lets advertisers call only people who agreed in advance to receive advertising, and requires a check of the national do-not-advertise list (people join by SMS to 5656 or at khongquangcao.ais.gov.vn). Press quotes Article 13 as allowing advertising calls from 8:00 to 17:00 unless the user agreed otherwise. A draft replacement decree appeared in September 2026; we could not confirm its status. The platform sets no calling window of its own; you set the hours per campaign. Read the official text; not legal advice.
Personal data and recording
The Law on Personal Data Protection (No. 91/2025/QH15) has applied since 1 January 2026, with Decree 356/2025/ND-CP; summaries say silence is not consent and you must be able to show proof of it, and that sending data abroad needs an impact assessment. We support region deployments for enterprise customers. Recording is off by default; tell callers if you switch it on. Read the official text; not legal advice.
