如何使用 AI 錄製演講並將其轉換為筆記 (最佳工具與技巧 2025)

Recording lectures is an essential strategy for students and educators alike. It allows you to revisit complex concepts, catch details you may have missed, and study more efficiently. Today, lecture recording software, AI-powered lecture note takers, and specialized lecture note taking apps have transformed the way we capture and organize lecture content — making it easier than ever to get accurate, searchable, and summarized notes without the stress of frantic manual writing.

This guide covers several simple but powerful methods to record lectures, both in-person and online, and how to leverage AI tools like VOMO to automatically transcribe and summarize your recordings for maximum learning benefits.

Record Lectures with a Recording Device or Smartphone

The best method is to record lectures using a recording device. Basically, everyone has one. You can use a digital voice recorder or your smartphone — both are portable and effective.

Here’s an introduction to common recording devices along with their pros and cons.

Generally speaking, if you don’t have very high requirements for audio quality, a smartphone or a digital voice recorder will be sufficient.

If you choose a recording device, memory capacity is important—opt for one with a larger storage size.

🎥 4. Cameras with Built-In Microphones

Best for recording video lectures or presentations with visual aids.

Examples: GoPro, DSLR cameras, or lecture capture systems

Pros: Visual + audio recording
Cons: Expensive and less user-friendly for beginners

Step 2: Test Sound Quality

Before the lecture, do a quick test recording to ensure clear audio capture.

Background noise and distance from the speaker affect quality.

It’s better to test it while someone is speaking.

Step 3: Get a Seat Close to the Lecturer

Try to arrive early to the classroom or lecture hall so you can get a seat closer to the podium.

Sitting near the lecturer improves audio clarity and helps avoid missing important points.

Step 4: Record the Full Lecture

It's best to get the lecturer's permission before recording.

Start recording before the lecture begins and let it run to the end without interruptions.

Step 5: Use AI Note Takers to Transcribe Automatically

After recording, upload the audio to a lecture AI note taker like VOMO. It automatically transcribes and generates searchable text, saving you hours of manual note-taking.

The usage is very simple; everything is automatic. Simply upload the audio, and you will get the transcription results and AI-generated notes.

Recording Lectures with a Laptop Using Note-Taking Softwares

The most common thing to bring to class is a laptop. You can also use a laptop to record lectures. Many lecture note taking softwares combine recording with real-time transcription:

Step 1: Find a Seat Near the Speaker

Find a seat as close to the speaker as possible. If possible, coordinate with the lecturer to let them know you need to sit in the front row. Make sure to arrive early to secure your spot.

Step 2: Prepare a computer microphone.

If possible, it’s best to use an external microphone with your computer because the built-in microphones on laptops often produce poor recording quality.

Step 3: Log In and Start Recoding Lecture

Use Software such as VOMO that support recoding lecture.

All you need to do is log in and select “Start Recording.” VOMO will automatically transcribe the recording into text once it's finished.

Step 4: Stop Recording and Review AI-Generated Notes

Once the lecture ends, you get a complete transcript with timestamps and the ability to highlight key points. This instant output helps you revise immediately.
