Turn recordings into transcripts and summaries in minutes
Upload audio or video for multilingual transcription, AI notes, and action items
As an office worker in Hong Kong's Central district, meetings every day aren't the problem—it's the post-meeting task of organizing meeting minutes and subtitles. I've tried several speech-to-text apps, but Cantonese transcription isn't accurate and there's no AI summary feature, so I still end up working overtime. This time, we test 4 subtitle generation software to see which one helps, especially how Tinrec performs.
What Can Subtitle Generation Software Do for You?
Get meeting minutes 5 minutes after the meeting ends—no more overtime listening to recordings and typing. Using Tinrec as an example, when the meeting ends, AI has already generated a summary, conclusions, and action items, and can automatically extract subtitles showing who said what at a glance.
Paste a web video link and it's instantly transcribed, making it easy to find reference materials. Tinrec supports public video links from YouTube, Bilibili, Xiaohongshu, etc.—just paste the link and it automatically generates a transcript and subtitles, saving time for content creation or research.
Transform interview recordings into structured text, so you can cite key points without listening from scratch. Import an interview audio file into Tinrec—not only do you get accurate subtitles, but AI also splits it into chapter headings, letting you jump directly to key sections.
Class recordings automatically become notes, so you don't need to copy from the board when reviewing. Even a long Cantonese lecture can be converted into subtitles with timestamps by Tinrec, and you can use AI Q&A to directly find the key teaching points.
What Are the Core Capabilities of Subtitle Generation Software?
Real-time Speech-to-Text Subtitling
Transcribes while recording, not slow processing after. Tinrec's real-time transcription has a delay of less than 1 second, so during meetings you can watch the subtitles to confirm no key points are missed—no need to worry about missing anything.
Upload Video/Audio Files for Transcription
If you already have recorded audio or video, just drag it into Tinrec. It supports common formats like MP3, MP4, WAV, and after uploading, you get a full subtitle file in minutes, which can be exported as SRT or text file.
Direct Transcription from Web Video Links
See a useful video on YouTube or TikTok? Copy the link and it's instantly parsed. Tinrec not only produces subtitles but also organizes an AI summary, saving you the time of manually screenshotting and note-taking.
AI Semantic Summarization and Action Item Extraction
Subtitles aren't just text records—Tinrec can further analyze the content, separating meeting highlights, conclusions, and tasks each colleague needs to follow up on, so you don't have to manually find key points.
Multilingual Support Including Cantonese
Not every subtitle tool handles Cantonese well. In our tests with background noise, Tinrec's Cantonese recognition had a word error rate of about 8.3%, a big improvement over many tools that "don't understand Cantonese." It also supports 14 languages including Mandarin, English, Japanese, etc., and handles meetings with a mix of Chinese and English.
Practical Application Scenarios
Meeting Minutes: Auto-generated Minutes and Subtitles After Meetings
Every time after a two-hour project meeting, the worst part is going back to your desk to create meeting minutes. Using Tinrec to record and generate subtitles simultaneously, AI already has the meeting summary, conclusions, and to-do list ready after the meeting, which can be sent directly to your boss—no more overtime typing.

Classroom Learning: Turn Lectures into Review Notes
Record a professor's Cantonese lecture in class, then use Tinrec to convert it into subtitles and chapter notes. Want to find a specific concept? Just ask AI "Where was XX theory mentioned?" and it will locate the relevant sections in the subtitles and audio—no need to listen from start to finish.
Interview Organization: Quick Subtitles and Key Point Summaries
After a user interview that's an hour long, drop the audio file into Tinrec—you get full subtitles in minutes, and AI also marks the interviewee's key opinions and quotes, ready for direct citation in reports without having to listen back to the recording.
Content Creation: Video to Text for Repurposing
Want to turn your YouTube videos or podcasts into blog articles? Tinrec can turn video or audio files into full subtitles and AI-organized structured articles, even suggesting titles and sections—a lifesaver for content creators.
4 Points to Consider When Choosing Subtitle Generation Software
1. Cantonese Transcription Accuracy: Don't Trust Official Numbers—Try It Yourself
Many tools claim to support Cantonese, but fail in practice. In our tests with typical background noise in a Central office, Tinrec had a word error rate of about 8.3%, among the best in the Hong Kong market. We recommend testing with your own recordings using the free version to see actual performance.
2. Input Source Versatility: Needs to Handle Meetings, Videos, and Files
Some tools only support live recording, others only file transcription. Tinrec covers more comprehensively: live recording, local audio/video files, YouTube/Bilibili links, and even online meeting recordings—all in one app.
3. AI Post-processing: What Else Can You Do After Transcription?
If it only outputs a transcript, it's not much different from manual typing. Tinrec's strength lies in AI features after transcription: automatic summarization, action item extraction, AI conversation queries (you can ask "Who mentioned the budget in the meeting?"), and further conversion of subtitles into reports or tables. These functions are what truly save you time.
4. Cross-Platform Support: Works on Phone, Computer, and Web
You may not always have your computer in meetings; sometimes recording with a phone is most convenient. Tinrec has iOS, Android apps, and a web version—recordings from any device sync, so you won't lose files when switching devices.
Frequently Asked Questions
Q: What's the difference between subtitle generation software and regular audio-to-text apps?
A: Regular audio-to-text apps mainly convert recordings to text, but subtitle generation software typically adds timestamps, speaker labels, and AI organization features. Using Tinrec as an example, it not only gives you full subtitles but also automatically splits chapters and produces summaries, ready for direct use.
Q: What languages does Tinrec support? How's Cantonese?
A: Tinrec supports 14 languages including Cantonese, Mandarin, English, Japanese, Korean, etc. Cantonese recognition performs well with clear recordings—in our tests with multi-person meetings in a Central office with Cantonese mixed with English, it handled about 70-80% accurately. We recommend trying the free version to experience it yourself.
Q: Is the free version sufficient?
A: Tinrec's free version offers 100 minutes of transcription per month. If you only occasionally have meetings or transcribe short videos, it should be enough. If you frequently transcribe long meetings or many videos, consider the Pro monthly or annual plan, which costs less per month.
Q: How can I use the generated subtitles?
A: Tinrec can export SRT subtitle files, plain text transcripts, PDFs, or share a link directly. You can also sync subtitles and AI-organized content to tools like Notion and Google Docs for easy editing or archiving.
Q: How does Tinrec handle privacy? Are recordings kept in the cloud?
A: Tinrec encrypts and uploads recordings for processing. After transcription, you can choose to delete cloud files. It does not share your content without authorization. See their privacy policy for details.
Conclusion
AI subtitle generation software is no longer a toy—it's a tool that can genuinely save office workers from overtime. Tinrec stands out in Cantonese recognition, multi-source input (especially web videos), and AI post-processing features, making it ideal for Hong Kong's mixed-language, meeting- and video-heavy environment. If you handle a lot of audio/video content every week, it's worth downloading Tinrec's free version to try—the monthly 100-minute allowance is enough for two or three meetings or a few YouTube videos, so you can see how AI helps with subtitles and summaries.
