Automating Zoom and Microsoft Teams Transcription with Vietnamese STT API
Streamline remote meetings by automating Zoom and Microsoft Teams transcription. See how AIVISION's Vietnamese STT API improves accuracy and workflow
In modern remote and hybrid work environments, online meetings on Zoom and Microsoft Teams happen with high frequency. Having to listen to entire recordings just to find specific information is a significant burden that reduces productivity. This article guides you on how to leverage advanced meeting speech-to-text (STT) technology to automate this process, helping you obtain accurate, clear, and fast Teams transcripts and Zoom transcripts.
Why You Need a Vietnamese-Specific STT System
Many users still rely on the default automatic note-taking features built into conferencing platforms. However, these integrated tools often struggle with the unique characteristics of the Vietnamese language, especially when speakers mix in English terms or use regional accents. Recognition errors can make the content processed by meeting recording AI difficult to read and cause the loss of important context.
AIVISION, a company specializing in speech AI solutions focused on Vietnamese, has built a Speech-to-Text system trained on a massive Vietnamese dataset of up to 690,517 hours. This ensures that the model deeply understands Vietnamese phonetics and context, minimizing spelling errors and improving accuracy.
Practical Benefits of Integrating an STT API into Zoom/Teams
When you integrate a powerful STT API into your workflow, the value you receive goes beyond raw text. Here are the specific benefits:
- Save time on minutes synthesis: Instead of spending hours listening to and retyping content, you simply review the converted draft.
- Instant information search: You can use Ctrl+F to instantly find a keyword, metric, or important decision within hours of meeting footage.
- Multilingual support: The system handles code-switching (mixing English and Vietnamese) effectively, which is very common in business meetings in Vietnam.
- Knowledge datafication: Transcripts can be stored, analyzed, and used as input data for project management or CRM systems.
Technical Process for Automating Transcription
To implement this solution, you do not need to be a deep-level programmer, but you need to understand the basic data flow. Here are the main steps to connect an STT API with a conferencing platform:
1. Collect Audio Data
The first step is to capture the audio stream from the meeting.
- For Zoom: You can use the Zoom API to access recordings after the meeting ends, or record locally if you are the host.
- For Microsoft Teams: Similarly, you can download .mp3 or .m4a recording files from SharePoint after the meeting.
2. Send Data to the STT API
Once you have the audio file, you send this data to AIVISION's server via REST or WebSocket protocols.
- REST API: Suitable for processing existing recording files (offline transcription). You upload the file and receive the result.
- WebSocket API: Suitable for real-time speech recognition if you need to display live subtitles during the meeting.
3. Process and Format Results
The API returns the converted text. A strength of AIVISION's technology is its ability to provide word timestamps. This allows you to synchronize text with audio, enabling users to click on a word to hear the exact part of the recording.
Comparison: Built-in STT vs. Specialized STT API
| Criteria | Built-in STT (Zoom/Teams) | Specialized STT API (AIVISION) |
|---|---|---|
| Vietnamese Accuracy | Average, depends on mic quality | High, trained specifically for Vietnamese |
| Code-switching Handling | Low, prone to spelling errors | Good, supports natural code-switching |
| Real-time Capability | Yes (depends on service plan) | Yes (via WebSocket, low latency) |
| Output Format | Usually plain text only | Text + Word Timestamps |
| Customization | Limited | High, integrate into internal systems |
Tips to Optimize Transcription Quality
To achieve the best results when using meeting recording AI, you should keep the following points in mind:
- Audio quality is key: Encourage participants to use headsets with good microphones or external mics. Background noise (air conditioning, keyboard typing) can affect recognition accuracy.
- Speaker Diarization: If the meeting has many speakers, try to separate audio channels if possible, or use speaker separation features if the API supports it. This helps make the Teams transcript clearer regarding who said what.
- Standardize Terminology: If the meeting uses many industry-specific terms (medical, finance, tech), consider providing a glossary to the system if possible, or carefully check important sections after receiving the results.

Frequently asked questions
How do I get the recording file from Zoom to feed into the STT API?
You can enable the recording feature in your Zoom meeting. After it ends, Zoom will send a link to download the recording file to your email. Download the file and upload it to AIVISION's STT API for conversion.
Does the STT API support recognizing English mixed within Vietnamese sentences?
Yes. AIVISION's models are trained to handle code-switching well, helping to accurately recognize both English and Vietnamese words within the same sentence.
How long does it take to process a 1-hour recording file?
Processing time depends on system configuration and bandwidth. With the REST API, this process is usually quick, much faster than manual listening, allowing you to get results in just a few minutes.
Do I need a credit card to try AIVISION's STT API?
No. AIVISION provides a free trial for every account, requiring no credit card or prepayment. You can sign up and use it immediately with a daily usage limit.
Is my meeting data secure?
