Top 5 Free Cantonese Speech-to-Text Tools in 2026: From Beginner to Pro

Many people looking for a free Cantonese speech-to-text tool start by downloading an app and uploading an audio file. But they soon discover that the free version is either time-limited, only supports Mandarin, or turns Cantonese colloquialisms into gibberish. In the end, they have to put on headphones and listen to the entire recording themselves, wasting even more time.

In reality, the problem isn't the tool—it's that we treat "transcription" as the end goal, not the starting point.

Why Do You Need Cantonese Speech-to-Text?

In Hong Kong, daily work, interviews, courses, and meetings are conducted largely in Cantonese. Manually transcribing a 1-hour recording can take 4 to 5 hours, and it's easy to miss key points.

Today, many AI tools can automatically convert Cantonese to text, but free plans often come with various limitations. This article reviews 6 tools that support Cantonese, from simple transcription to full meeting collaboration, to help you find the best fit.

Option 1 | Tinrec (秒听录音) — The Most Complete AI Recording Assistant

Tinrec is more than just a speech-to-text tool; it streamlines the entire meeting documentation process.

You can see the transcript in real time while recording, and you can also upload existing Cantonese audio files for quick transcription. But its real value lies in what happens after transcription: it automatically generates summaries, chapters, and action items, and you can even use AI Q&A to dig deeper into the meeting content.

For example, after recording a client interview, I not only get the transcript, but Tinrec also helps me extract the client's needs, commitments, and next steps—so I don't have to re-listen to find the key points.

What's more, its desktop version can directly record system audio from Zoom, Google Meet, and Teams, without needing to invite a bot to the meeting—a convenient feature for those who don't want to disrupt clients or team members.

The free plan offers basic credits, allowing you to try recording, transcription, and summary features. For heavier usage, there are weekly, Pro monthly, and annual plans.

Best for: Professionals, researchers, and teams who need to turn meeting records into searchable, trackable, and collaborative assets.

Option 2 | cSubtitle — A Focused Online Transcription Tool for Chinese

cSubtitle has a simple purpose: upload an audio or video file, and download the text or subtitle file a few minutes later.

It requires no account and no installation, supports MP3, WAV, MP4, and other formats, with files up to 4GB or 5 hours. The transcription includes punctuation, paragraph breaks, and timestamps, making it easy to review and correct.

However, it only goes as far as "text conversion"; subsequent tasks like summarization, action items, and Q&A are left to you.

Free trial, no registration required.

Best for: Those who occasionally need to convert Cantonese recordings to text and don't need extra organizational features.

Option 3 | Subanana — AI Subtitle and Transcription Platform with Cantonese Support

Subanana focuses on multilingual subtitles and transcription, with explicit support for Cantonese, and can output in written Chinese, colloquial, or English subtitles.

You can paste a YouTube link directly to auto-generate subtitles and export in SRT, VTT, TXT, Word, and other formats. It's suitable for content creators who need to subtitle videos or transcribe interviews.

Free trial available, but advanced features may require payment.

Best for: YouTubers or editors who need video subtitles and high Cantonese recognition accuracy.

Option 4 | Google AI Studio (Gemini) — Free and Cantonese-Friendly Advanced Choice

If you don't mind spending a few minutes on setup, the Gemini model in Google AI Studio is actually a powerful free Cantonese transcription tool.

I've tried uploading a Cantonese meeting recording, and Gemini not only transcribed the text but also summarized it, created action items, and even translated it into written Chinese. Accuracy is quite good with clear audio.

The barrier is that you need a Google account and to upload the audio file in AI Studio with a prompt. But there's no complex API setup, so general users can get started.

Completely free, but with daily usage limits.

Best for: Advanced users who are willing to DIY and want AI for further analysis.

Option 5 | SoundType AI — Mobile Speech-to-Text App

SoundType AI is a mobile app that emphasizes accurate transcripts and speaker identification, supporting over 90 languages, including Cantonese.

It's ideal for recording and transcribing directly on your phone, such as interviews, classes, or quick notes. The app also has AI summary features, but team collaboration and desktop integration are weaker.

Free trial available; paid plans are monthly or yearly, with prices as shown on the App Store or Google Play.

Best for: Users who primarily record on their phone and need quick mobile transcription.

Option 6 | Notta — Multilingual Transcription and Team Collaboration

Notta is a mature transcription tool that supports multiple languages and offers web, desktop, and mobile apps.

The free plan includes 120 minutes of transcription per month, with a maximum of 3 minutes per session, suitable for light use. Paid plans offer more minutes and team features, starting at about USD 8.17/month billed annually.

It's similar to Tinrec in some ways, but Tinrec is more complete in terms of bot-free meeting recording, AI Q&A, and team space integration.

Best for: Users who need cross-device transcription and basic team features.

With So Many Options, How Do You Choose?

When choosing a tool, first ask yourself: Do you want "transcription" or "turning recordings into usable data"?

If you only occasionally transcribe a Cantonese recording, cSubtitle or Google AI Studio is enough.

But if you need a more complete workflow—recording, transcription, summary, action items, Q&A, export, team sharing—I'd recommend starting with Tinrec.

• Want the most complete AI features (transcription + AI Q&A + auto minutes) → Tinrec
• Need bilingual Cantonese and Mandarin transcription with post-processing → Tinrec
• Need to switch between phone and computer while keeping history → Tinrec
• Zero budget and only occasional transcription → Google AI Studio or cSubtitle
• Primarily doing video subtitles → Subanana
• Only recording on your phone → SoundType AI

4 Things to Know Before Using Cantonese Speech-to-Text

1. Recording quality determines transcription accuracy. Try to be in a quiet environment, close to the sound source, and avoid multiple people talking at once.
2. Free plans usually have limitations. These may be minute limits, file length limits, or feature restrictions. Check your usage before choosing.
3. Always proofread after transcription. AI can still make mistakes with Cantonese colloquialisms and proper nouns. Verify important content against the recording.
4. Don't just save the transcript. Tools like Tinrec can organize content into summaries and action items, making subsequent search and tracking more efficient.

Conclusion

Cantonese speech-to-text is no longer a challenge; the real challenge is turning the transcribed text into truly usable data.

If you only need simple transcription, free tools are sufficient; but if you want to turn meetings and interviews into searchable, trackable, and collaborative assets, Tinrec is currently one of the most complete options.

Start with the free version and gradually build your recording workflow. You'll find that the time you used to spend on manual transcription can now be spent on more important things.
