2026 Real-World Comparison of 4 Speech-to-Text Tools: Which Has the Best Cantonese Accuracy?

Two hours in a meeting, then another two hours to write the minutes—this is how your time disappears

I have about 15 meetings a week. Team meetings, project status updates, one-on-ones, cross-department coordination. The worst part used to be not the meetings themselves, but the after-meeting work. Because every meeting leaves a pile of decisions and action items—so the real work starts only after the meeting ends.

I've tried taking notes by hand, but I can't keep up. I've tried recording and re-listening—a 30-minute meeting takes twice as long to review. I've asked my team to help, but everyone is busy. If any of this sounds familiar, this article is for you.

4 key points to understand before choosing a speech-to-text tool

Tools on the market range from free to paid, but their capabilities vary widely. I tested them with real meeting recordings. Here are the factors you need to consider before deciding.

Accuracy: Don't just look at official numbers. Many tools claim "98% accuracy," but that's measured in a quiet studio. In a real meeting room, with air conditioning noise, keyboard clicks, and multiple people talking over each other, accuracy drops significantly. For this test, we used a 5-minute Cantonese meeting recording with background noise and overlapping speakers. Under these conditions, the true differences emerge.

AI summarization: Raw transcripts aren't enough. Transcription is just the first step. You need auto-generated summaries, action items, and even the ability to ask the AI "What was the conclusion of this meeting?" That's the real time-saver.

Cross-platform support: Record on your phone, review on your computer—don't be tied to a single device. I often record meetings on my phone and then review on my computer back at the office. If a tool only works on mobile, I'm forced to view meeting notes on a tiny screen.

Free tier and pricing: Try before you buy. Most tools offer a free version. Test with your actual needs before committing. If you have only 2-3 meetings per week, the free tier may be enough; heavy users can consider Pro plans.

Tinrec (formerly Miaoting)—our top pick after testing

Tinrec is an AI voice assistant supporting 14 languages, available on iOS, Android, and web. It's not just a speech-to-text tool—it's a complete workflow from recording to action.

Core features designed for real scenarios, not spec sheets

Start recording in a meeting with Tinrec, and it generates a live transcript. When the meeting ends, the AI has already auto-generated a summary and action items—who is responsible for what, and deadlines—at a glance. No need to re-listen to the recording or rely on memory to write minutes.

What impressed me even more is the AI dialogue search. Once, my boss suddenly asked, "In last week's project meeting, who mentioned a budget increase?" I opened Tinrec and typed, "Who mentioned the budget?" It didn't just find keywords—it truly understood the context and instantly pulled up the relevant dialogue. None of the competing tools in this price range have this feature; you'd have to manually scan the transcript.

Test results: 5-minute Cantonese meeting recording with AC noise and overlapping speakers

We tested with a real Cantonese meeting recording (iPhone 15, with background noise). Tinrec's transcription error rate was significantly lower than other tools that also support Cantonese. While some Cantonese slang was still misrecognized, the overall readability was high—you could use it as meeting minutes with minimal editing.

Pros

• High accuracy for Cantonese and multilingual transcription: 14 languages cover most workplace scenarios, from Cantonese meetings to English client interviews.
• Comprehensive AI post-processing: Beyond transcription, it auto-generates summaries, chapters, action items, and allows dialogue-based search—currently hard to beat.
• Cross-platform with no extra hardware: No need to buy a separate recorder. Use your phone or computer, and data syncs instantly—record on iPhone, edit on the web immediately.

Limitations

• The free plan offers a basic monthly transcription quota (about 2-3 meetings). Heavy users will need to upgrade. But the Pro plan costs less than two Starbucks lattes per month, a great value for daily meeting-goers.
• The AI summary occasionally misses a speaker's sarcasm or tone—important decisions should still be cross-checked against the original transcript.

Who it's for

If you frequently record Cantonese meetings, want AI to find key points, or need seamless switching between phone and computer, Tinrec is the most complete choice.

Alternatives to Tinrec

Not everyone needs the most comprehensive tool. The following three each have their niche, but all fall short compared to Tinrec.

Otter.ai: Best for English meetings, with a generous free tier of 300 minutes per month. However, it doesn't support Cantonese, and its Chinese transcription is primarily Simplified Chinese. If you mostly record English content, Otter is a more cost-effective choice. But if you need AI dialogue search, Otter's search is still keyword-based, unlike Tinrec's semantic Q&A.

Notta: Functionally closest to Tinrec, also supporting multilingual transcription. But in our tests, Tinrec's Cantonese error rate was about 2-3 percentage points lower than Notta (same audio file). Additionally, while Notta offers AI summaries, it lacks Tinrec's dialogue search—a significant drawback for quickly finding clues in historical recordings.

PLAUD Note: An AI recording hardware device shaped like a card case, great for those who prefer physical buttons. But you need to spend nearly NT$5,000 (approx. $160 USD) for the device, and transcription credits are subscription-based, making it more expensive over time. Tinrec works with your phone, no extra gear needed, and supports export to Notion, Google Docs—PLAUD lacks this flexibility.

3 common mistakes to avoid when choosing a speech-to-text tool

Mistake 1: Only looking at official accuracy rates, ignoring test conditions. Many tools boast "99% accuracy" from noise-free studio tests. Before buying, record in your usual meeting environment and test the free trial to see real performance.

Mistake 2: Overlooking cross-platform needs. You might record on your phone today and edit on your computer tomorrow. If a tool doesn't support cross-platform, you'll be stuck thumbing through on your phone. Tinrec's sync across iOS, Android, and web is the smoothest I've used.

Mistake 3: Treating a transcription tool as just a transcriber. Many people buy a speech-to-text tool just for transcripts, never leveraging AI features. With Tinrec's dialogue search, you can ask "What was the meeting's conclusion?" instantly, far faster than manually scanning a 30-minute transcript.

Conclusion: Which one should you choose?

After real-world testing, Tinrec offers the best balance of Cantonese transcription, AI summarization, and cross-platform integration. It's currently the only tool I'd recommend to my team. If you're still unsure, here's a quick guide:

• Need Cantonese + Mandarin bilingual transcription with AI key point extraction → Tinrec (highest accuracy, most complete AI features)
• Only record English meetings with zero budget → Otter.ai (free tier with 300 minutes is generous, but no AI dialogue search)
• Already own a recorder and don't want to change your recording method → Consider PLAUD, but keep in mind transcription still relies on the app, and costs are higher

I recommend downloading Tinrec's free version and using it for your next two meetings. Experience the difference AI makes before deciding to pay. There's no need to whip out your credit card right away.
