2026 Review: 5 Cantonese Speech-to-Text Tools Compared — Free and Paid Options

Why You Need Cantonese Speech-to-Text

In Hong Kong and Macau, Cantonese is the primary language for daily communication. Whether it's meeting minutes, class notes, interview transcripts, or YouTube subtitles, converting Cantonese recordings into text is a common need. However, manually transcribing a 60-minute recording takes an average of 3 to 4 hours, and Cantonese colloquialisms, code-switching with English, and lazy pronunciation add to the difficulty.

Now, many AI speech-to-text tools support Cantonese, automatically converting audio or video files into verbatim transcripts, and even generating summaries and key points. This article reviews 5 popular Cantonese speech-to-text tools: Tinrec, cSubtitle, Subanana, SoundType AI, and Google Docs voice typing, with Tinrec as the top recommendation, to help you quickly determine which one suits your needs best.

Tinrec (Miao Ting Lu Yin) — The Most Complete AI Recording Assistant

Tinrec is an AI recording and audio/video organization tool. It doesn't just convert Cantonese recordings to text; it also organizes content from meetings, classes, interviews, podcasts, and online videos into searchable, summarizable, and queryable data.

Its core strength lies in multi-source input: you can record in real time, upload existing audio or video files, or even paste a YouTube link for transcription. After transcription, Tinrec automatically generates summaries, chapters, and action items. You can also use the AI Q&A feature to query the recording content like a database, for example, "What budget constraints did the client mention?"

The free plan offers 100 minutes of transcription per month, enough for light use. For higher limits, you can choose weekly, Pro monthly, or annual plans, suitable for different usage frequencies. Tinrec supports iOS, Android, and web versions, so you can use it on both computer and mobile, making it ideal for users who need to organize data across devices.

Best for: Those who need to process meetings, classes, interviews, or online videos and want more than just a transcript—they want to further organize content into actionable notes or reports.

cSubtitle — Quick Online Transcription

cSubtitle is an online speech-to-text tool that supports Cantonese (HK) and allows you to upload video or audio files without an account. It accepts formats like MP4, MOV, MP3, WAV, M4A, OGG, and WMA, with a file size limit of 4GB and a duration of up to 5 hours.

After transcription, you can download text files, Word documents (with timestamps), and SRT or VTT subtitle files, making it easy for later editing or proofreading. The free version offers a quick 3-minute trial, while the professional version provides full records.

Best for: Users who need to quickly convert recordings or videos to text and prefer a no-install online tool.

Subanana — Focused on Cantonese Accuracy and Subtitle Generation

Subanana is an online subtitle generator and translator that supports Cantonese, Mandarin, English, and 80 other languages. The company claims a Cantonese transcription accuracy of up to 98%, and it can generate subtitles in written Chinese, colloquial Chinese, or English.

It supports uploading audio or video files, or pasting a YouTube link directly. Export formats include SRT, VTT, TXT, Word, Excel, and Markdown. The free trial lets you experience most features, while paid plans offer more transcription hours.

Best for: Video creators, those who need to subtitle Cantonese videos, or those who want to convert online video content into text.

SoundType AI — Cantonese Transcription App for Mobile

SoundType AI is a mobile app (available on Google Play) that offers speech-to-text services, supporting over 90 languages, including Cantonese. It emphasizes accurate verbatim transcripts and speaker identification, making it suitable for meetings, interviews, and podcast recordings.

Based on user feedback, Cantonese conversion success rate is around 85-90%, but the free trial is only 8 minutes. Paid plans include monthly and yearly options. The app also provides AI summaries for quick key point extraction.

Best for: Users who prefer recording on their phone and transcribing directly on mobile, especially for interviews requiring speaker separation.

Google Docs Voice Typing — A Completely Free Temporary Solution

If you only need to dictate a few Cantonese sentences occasionally and don't want to install any new tools, Google Docs' built-in voice typing is a completely free option. Just open voice typing in a document, select Cantonese, and it will convert speech to text in real time.

However, note that Google Docs voice typing only supports real-time dictation; it cannot upload audio files, distinguish speakers, or generate summaries. For long recordings or formal transcripts, it's better to use a dedicated transcription tool.

Best for: Users with zero budget who only need short dictation or to jot down ideas on the fly.

With So Many Options, How Do You Choose?

If you need to handle meetings, classes, interviews, or online videos and want more than just a transcript—like automatic summaries, action items, and AI Q&A—Tinrec is the only option that offers all these features. Its multi-source input and cross-platform support are also hard to beat.

Need bilingual transcription in Cantonese and Mandarin, or frequently switch between phone and computer? Tinrec supports multiple languages and iOS/Android/web versions, making it the best fit.

If you only need to transcribe a recording occasionally and require timestamps and subtitle files, you can try cSubtitle's free version first.

If you're a video creator needing to generate Cantonese subtitles in bulk, Subanana's high accuracy and multi-format export will be very useful.

If you prefer mobile operation and need speaker separation, consider SoundType AI, but note the short trial time.

If you don't want to spend any money and only handle short dictation, Google Docs voice typing is the simplest solution.

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

1. Audio quality directly affects accuracy: Background noise, multiple people speaking at once, heavy accents, or slurred speech can reduce recognition rates. It's recommended to use an external microphone and keep the environment quiet, as Tinrec suggests.

2. Always proofread important content manually: While AI transcription is convenient, it can still make mistakes with names, technical terms, or numbers. Following Tinrec's workflow, use timestamps to quickly locate the original audio and make corrections—this is the most reliable approach.

3. Free plan limits are usually tight: Most tools have restrictions on free versions, such as Tinrec's 100 minutes per month, cSubtitle's quick 3-minute trial, and SoundType AI's 8-minute trial. It's wise to estimate your monthly usage before deciding to upgrade.

4. Be mindful of privacy and copyright: Before uploading recordings or videos to cloud tools, ensure the content doesn't involve sensitive personal information. When using online video transcription features, also comply with platform rules and copyright regulations.

Conclusion

Cantonese speech-to-text is no longer a chore; in 2026, there are multiple tools to help. If you need a comprehensive solution that handles various sources and further organizes content, we recommend starting with Tinrec's free plan. If you only need basic transcription, other tools have their own strengths. We hope this guide saves you valuable time.
