2026 Comparison of 4 Cantonese Speech-to-Text AIs: Which Saves the Most Time on Cantonese Transcripts?

Cantonese speech-to-text—the real challenge has never been 'which tool is the most accurate.'

It's what this recording in your hands ultimately needs to become.

A written-language transcript you can paste directly into meeting notes? An SRT file for subtitles? Or a meeting database your colleagues can go back and query?

These three answers will point to completely different tools and workflows.

My decision order is: output first, then language, and finally price.

Below, I'll walk through my usual Cantonese recording workflow using Tinrec, and I'll honestly explain which parts it suits and which parts you should supplement with other tools.

Before You Start | What You Need to Prepare

Before you begin, confirm these four things:

• A recording containing Cantonese (meetings, interviews, classes, or phone calls are all fine; start with a short 10- to 20-minute file)
• A Tinrec account (the personal plan is enough to start; the free quota lets you try the full workflow)
• The output format you want—write it down first (transcript, summary, to-do list, subtitle file)
• Obtain consent from participants before recording, and confirm the relevant regulations for your setting

The fourth point is the most overlooked.

But it's the only step in the entire workflow that cannot be remedied.

Step 1 | Define the Output Format Before Opening Any Tool

The purpose of this step is to avoid spending two hours producing something you can't use at all.

My approach is to spend thirty seconds writing one line on paper: 'A week from now, who will open this recording, and what will they use it for?'

If the answer is 'the manager wants to see the decisions,' you need a summary and to-dos, not a transcript.

If the answer is 'editing for subtitles,' you need a subtitle file with time codes.

If the answer is 'research citation,' you need a complete, searchable transcript.

Why think about this first? Because 90% of the differences between tools show up 'after output,' not 'during transcription.'

Most tools differ only slightly in accuracy; the big difference is whether the result can directly become what you need.

Once done, you'll have clear acceptance criteria to check each subsequent step against.

Step 2 | Ensure Recording Quality—This Step Determines 80% of the Result

The purpose of this step is to make all subsequent steps easier.

Cantonese has many tones and dense sentence-final particles, and overlapping speech is especially prone to blurring together.

So when recording, I only do two things: place the microphone close to the speaker, or in meetings, place it in the center of the table.

Recordings captured from a distance are a bottomless pit no matter how much proofreading you do afterward.

Rather than spending time fixing errors later, spend thirty extra seconds confirming placement before recording.

If the recording is already done, don't re-record—just select the appropriate environment type when importing, and let the tool use more conservative parameters.

Once done, you'll have a clean audio file without large areas of echo.

Step 3 | Let AI Transcribe for You

The purpose of this step is to turn sound into searchable, quotable text.

Open Tinrec, and you can record live directly or import existing audio or video files.

It covers Chinese and multilingual meeting scenarios, and handles mixed Chinese-English segments as well.

But I want to remind you: any tool's performance on Cantonese will be affected by accent, speaking speed, noise, and overlapping speech.

No tool performs equally well on all recordings.

So my approach is—first run a segment of your own recording using the free quota, then decide whether to invest more based on the results.

This is also my consistent advice for all AI tools: validate with your own material, don't decide based on someone else's benchmark numbers.

Once done, you'll get a transcript with timestamps.

Step 4 | Proofread and Lock In Proper Nouns with Hotwords

The purpose of this step is to fix 'errors you have to correct every time' only once.

Transcripts will inevitably mishear names, company names, and product codes.

My habit is to first scan quickly and note recurring proper nouns.

Then add these terms to team hotwords.

Why do this specifically? Because it's the only action that makes 'next time' faster.

Ordinary transcription tools only help you with this one recording; tools that retain terminology will get smoother over time.

For team use, one person maintains the hotwords, and the whole department benefits.

Once done, your transcript error rate will drop noticeably, and next time will be even better.

Step 5 | Turn the Transcript into Usable Post-Meeting Material

The purpose of this step is to make the recording truly enter the workflow, rather than sit in a folder.

The transcript is just raw material.

I then do three things: view the AI summary to grasp the big picture, view chapters to jump to key sections, and extract to-dos for assignment.

If there's something you didn't understand or want to follow up on in the meeting, you can ask questions directly about the meeting content without re-listening to the whole segment.

Finally, export—to Notion, Google Docs, OneNote, or Dropbox for further editing.

When you need formal deliverables, you can further generate reports, tables, and meeting minutes.

Once done, you'll have a result you can send out directly or put straight into project documents.

FAQ and Troubleshooting

Q: There are many errors in the transcription. What should I do?

First check the recording environment—usually the distance is too far or the background is too noisy. Next, check whether multiple people were talking over each other. After improving these two things, the results usually bounce back immediately.

Q: Will mixed Chinese-English segments get cut off incorrectly?

Cantonese meetings often have 'English terms mixed into Chinese sentences.' For such content, I recommend keeping the original appearance and not rushing to rewrite; it's more efficient to organize it uniformly afterward.

Q: I need written language, not a colloquial transcript

This is the most unique need in Cantonese transcription. Some Cantonese-specific tools directly offer an option to convert colloquial speech to written language.

My approach: keep the transcript in its original form (for easy verification and citation), and separately produce a written version using summaries and post-meeting documents.

One copy for evidence, one copy for people to read.

Q: How do we manage it when multiple team members need to use it together?

Personal accounts are not suitable for shared use. Tinrec's team plan is a separate team space that can manage roles, seats, shared benefits, usage, and activity logs; members without a seat can still view and read team materials, but need a seat to record, upload, and edit.

Q: If a member leaves, will their data disappear too?

Team data belongs to the team. When a member exits or is removed, the resources they were responsible for need to be handed over to other active members.

Advanced Tips | 3 Methods to Double Your Efficiency

1. No bot needed to join online meetings

Tinrec's desktop version directly captures computer system audio, handling meetings like Zoom, Google Meet, Teams, and Webex without an extra bot joining.

This is especially useful for external client meetings—you don't have to explain 'there's an extra participant' to the other party.

2. Treat past meetings as a queryable database

A single meeting has limited value; ten meetings together are an asset.

Before a project ends, I ask questions about the entire series of meeting materials to quickly review how decisions evolved.

This is something the transcript alone cannot do.

3. Let it settle in team space, not chat groups

Meeting links pasted in a group chat become unfindable three months later.

Once placed in team space, new members can browse historical materials themselves, and managers can see usage trends.

The team plan currently offers a 7-day trial with 1 free seat and 300 minutes of shared team import quota; paid seats provide 2,000 minutes of shared team import quota per month. Actual prices and benefits are subject to the official purchase page.

If You Don't Use Tinrec, Here Are Other Options

CantoSub: Focuses on Hong Kong Cantonese, Guangzhou dialect, Dongguan dialect, Shunde dialect, and other Cantonese branches. It can automatically convert colloquial speech to written language and output Traditional Chinese. New users get a 30-minute trial quota. If your need is purely Cantonese transcription and you care a lot about Cantonese branches, it's worth trying first.

Subanana: Supports file upload and pasting links, outputs transcripts with speaker separation and punctuation added. The first 15 minutes of each file can be previewed for free; export is a paid feature. Suitable for seeing results before deciding.

Both lean toward 'transcription and subtitles'; if you want post-meeting summaries, to-dos, follow-up questions, and team data retention, the workflow will still come back to tools with complete post-processing.

Conclusion

Looking back at these five steps, what really takes time has never been which button to press.

It's the two seemingly boring things: 'define the output first' and 'ensure recording quality.'

Quick-start checklist:

1. Write one line: who will use this recording a week from now, and for what
2. Confirm microphone placement; for multi-person meetings, place it in the center of the table
3. Run a segment of your own recording using the free quota first
4. Scan for proper nouns and add them to hotwords
5. Use summaries and chapters to grasp the big picture, and extract to-dos
6. Export into your existing workflow

Tools will change; methods will remain.

Take the most troublesome Cantonese recording you have on hand and try it once—you'll quickly know which part of your workflow is still missing. Test step by step, and you'll gradually master this method.
