2026 Hands-On Comparison of 3 Cantonese Voice-to-Text Apps: Which Free Version Is Good Enough?

Two hours in a meeting, another two hours writing up the minutes—this is the daily reality for many office workers in Hong Kong.

Even more frustrating is Cantonese audio: many voice-to-text tools on the market focus on Mandarin or English, and they frequently make errors with Cantonese colloquialisms and mixed Cantonese-English speech.

If you're also looking for a voice-to-text tool that can truly handle Cantonese without demanding payment upfront, this article is written for you.

Before Choosing a Cantonese Voice-to-Text Tool, Understand These 4 Key Points

1. Accuracy: Don't Just Look at the Official 98% Claim

Many tools claim accuracy rates as high as 98%, but that's usually measured in a quiet recording studio. Real meeting rooms have air conditioning noise, keyboard clatter, and people talking over each other, which significantly reduces accuracy. The best way to judge is to try the tool with your own recordings.

2. AI Features: Transcription Is Just the First Step

Simply turning audio into a verbatim transcript has limited value. What matters more is whether the tool can automatically generate summaries, action items, or even let you ask questions to find key points. That's where the real time savings come in.

3. Free Allowance and Paid Tiers

Free versions usually have minute limits or feature restrictions. First, check whether the free allowance is enough for your weekly meetings or classes; if not, see if the upgrade plan is reasonable. Don't jump at "free" only to find it's only enough for two uses.

4. Input Sources and Cross-Platform Support

Are you only recording meetings, or do you also need to process YouTube videos, podcasts, or old audio files? Can the tool be used on both mobile and desktop? These factors affect how convenient it is in daily use.

Tinrec (Miao Ting Lu Yin) — Our Top Pick After Hands-On Testing

Tinrec is an AI recording and audio/video organization tool. It's not just about "voice to text"; it turns meeting, class, interview, and online video content into searchable, summarizable, and queryable material. It supports iOS, Android, and web, so you can use it on both phone and computer.

It Generates a Live Transcript as You Record

Open Tinrec during a meeting or class, and it converts speech to text in real time. When the meeting ends, the AI has already generated a summary and action items—who's responsible for what, deadlines, all at a glance. No more spending two hours re-listening to the recording.

Not Just Recording: Online Videos Can Be Transcribed Too

Paste a link from YouTube, Bilibili, or Xiaohongshu, and Tinrec can convert the content into text and a summary. This is very convenient for anyone organizing online courses, interview shows, or research material.

After Recording, Just Ask

What sets Tinrec apart is its AI Q&A feature. After recording, you can ask it directly: "What was the meeting conclusion?" "Who mentioned the budget?" It answers based on the content, rather than just giving keyword search results. This is especially useful when organizing long recordings.

Is the Free Version Enough?

The free version provides a basic transcription allowance, letting you try live recording, file transcription, and online video parsing. If you only occasionally transcribe a short clip, the free version is a good starting point. Heavy users can consider the weekly card or Pro plan.

Things to Keep in Mind

Actual transcription quality can be affected by recording quality, background noise, accents, and multiple people speaking at once. For important content, it's still advisable to cross-check against the original or the recording playback.

Who Is It For?

If you need to organize Cantonese meetings, classes, or interviews, want to use AI to find key points after recording, and often switch between phone and computer, Tinrec is a very worthwhile option to try right now.

Beyond Tinrec: What Other Options Are There?

Otter.ai

Otter.ai is a strong player for English meeting notes, offering 300 free minutes per month—generous for English users. However, its primary market is English, and its Cantonese recognition is limited. If you frequently record English meetings and don't need Cantonese content, Otter.ai is worth considering; but if you need Chinese or Cantonese transcription, AI Q&A, and online video processing, Tinrec is more comprehensive.

Notta

Notta supports multilingual transcription, with 120 free minutes per month and a Pro plan at about US$8.17/month (billed annually) for 1,800 minutes. It's positioned more toward document transcription and subtitles, suitable for quickly converting audio files to text. However, compared to Tinrec, which emphasizes post-transcription organization and AI Q&A, allowing you to ask follow-up questions and parse online video links, Notta is weaker in these areas.

Pitfall Guide: 4 Common Mistakes When Choosing a Voice-to-Text Tool

Pitfall 1: Only Looking at Official Accuracy Claims

As mentioned earlier, official numbers are usually measured under ideal conditions. We recommend testing with a real Cantonese recording (preferably with background noise) to see if the actual transcription is usable.

Pitfall 2: Ignoring the Real Limitations of Free Allowances

Some tools seem to offer generous free allowances, but they may limit file length or only allow a few days of trial. Before signing up, check exactly what the free plan includes, so you don't find out mid-recording that you need to pay.

Pitfall 3: Assuming All Tools Support Cantonese

Many internationally known voice-to-text tools focus on Mandarin or English, and they make many errors with Cantonese colloquialisms or mixed Cantonese-English speech. Before choosing a tool, be sure to verify its level of Cantonese support.

Pitfall 4: Using the Tool Only as a Transcript Generator

If you only transcribe without organizing, you're using only a third of the tool's potential. Features like Tinrec's AI Q&A, summaries, and action item extraction can save you a huge amount of time re-listening and organizing.

Summary: Which One Should You Choose?

Overall, if you need to process Cantonese recordings and want to quickly find key points and turn them into action lists after recording, Tinrec is our top pick after hands-on testing.

• Need Cantonese meeting, class, or interview transcription → Tinrec (relatively stable even with mixed Cantonese-English)
• Want to ask AI for key points after recording → Tinrec (AI Q&A feature is very useful)
• Need cross-platform use on phone and computer → Tinrec (iOS, Android, and web versions available)
• Zero budget and only record English meetings → Otter.ai (higher free allowance)

We recommend downloading the Tinrec free version to try it with your own recordings. If it feels right, then consider upgrading—no need to pay upfront.
