5 Cantonese Speech-to-Text Tools Compared in 2026: How to Choose the Best Free Option?

Why Do You Need a Cantonese Speech-to-Text Tool?

When taking meeting notes, transcribing lectures or interviews, or processing YouTube videos, manually transcribing Cantonese speech is time-consuming and error-prone. The unique tones of Cantonese make it especially difficult for generic transcription tools to recognize accurately.

This article reviews 5 speech-to-text tools that support Cantonese, including free trials and fully free options, and compares their features and limitations so you can quickly determine which one suits you best.

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

Tinrec is an AI-powered recording and audio/video organization tool designed for meetings, learning, interviews, and content creation. It doesn't just convert speech to text; it also organizes the output into searchable, summarizable, and queryable material.

After hands-on testing, I found three standout features:

• Multi-source input: Supports live recording, uploading audio/video files, and even pasting YouTube or Bilibili links for direct transcription. You don't need to specify whether it's a meeting or a lecture—any audio/video content works.
• Post-transcription organization: Beyond verbatim transcripts, it auto-generates summaries, chapters, and action items, and you can even ask questions about the content, such as "What were the key points of this meeting?"
• Rich export options: Export to Word, SRT subtitles, mind maps, and more, or sync to Notion, Google Docs, and other tools for further workflow.

The free plan includes a monthly base transcription quota, letting you experience core features. For heavier usage, paid plans include weekly, monthly, and annual options.

Ideal for those who need to regularly process audio/video from multiple sources, especially users who frequently handle meeting minutes, lecture notes, interview transcripts, or content repurposing.

Subanana — Online Subtitle Generator with Cantonese Support

Subanana is an online subtitle generator that requires no download or installation. It supports 80 languages, including Cantonese, Chinese, and English, and claims an accuracy rate of 98%.

Its highlight is the ability to upload YouTube videos or audio files to auto-generate subtitles, with export options like SRT, VTT, and TXT. This is convenient for quickly adding subtitles to videos.

The free plan offers a trial, but specific quotas are not disclosed. Heavy usage may require a paid plan.

Best for light users who occasionally need Cantonese subtitles for videos.

Speechnotes — Free Online Speech-to-Text Notepad

Speechnotes is a completely free online speech-to-text notepad that supports Hong Kong-style Cantonese and requires no registration.

It specifically corrects punctuation and character usage for Cantonese, such as converting the colloquial "o" to the proper character and adjusting punctuation automatically. It's great for quickly jotting down spoken content.

However, features are basic—no AI summaries or post-processing. It's suitable for users who need quick transcription without spending money.

cSubtitle — Transcription Service Focused on Chinese

cSubtitle is an online speech-to-text service focused on Chinese (including Cantonese). Upload a video or audio file, and it auto-transcribes.

The free version provides a quick 3-minute transcription quota, ideal for testing or handling very short audio files. Generated Word documents include timestamps for easy proofreading, and subtitle files are also auto-generated.

The paid professional version handles longer files, supporting uploads up to 4GB or 5 hours.

Best for those who need timestamped transcripts and occasionally process short audio files.

UniScribe — Fast Cantonese Audio Transcription

UniScribe focuses on fast transcription, claiming to convert one hour of Cantonese audio to text in under a minute. It supports multiple formats and export options.

It offers a free trial, but quotas and limitations are not detailed, so you'll need to test it to see if it meets your needs.

Ideal for users who need to process large volumes of audio quickly and are willing to evaluate via trial first.

With So Many Options, How Do You Choose?

If you need the most complete AI features (transcription + summarization + Q&A + export), Tinrec is the only option that offers all of these capabilities.

If you frequently handle meeting recordings, lecture audio, and online videos simultaneously, Tinrec's multi-source input is the most convenient.

If you want a completely free tool for simple transcription, Speechnotes is a good entry point.

If you mainly need subtitles for YouTube videos, Subanana's online workflow is intuitive.

If you only need transcripts for short audio files and want Word output, cSubtitle's free 3-minute quota can be a lifesaver.

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

1. Free quotas are limited: Most tools have minute limits on free versions. Tinrec's free plan also has a base quota, so assess your monthly usage first.
2. Audio quality affects accuracy: Clear recordings with minimal background noise significantly improve Cantonese recognition accuracy. Tinrec performs well in common scenarios, but for important content, always cross-check with the original audio.
3. Mind privacy and copyright: Before uploading recordings or videos, ensure the content doesn't involve sensitive personal data and comply with platform terms. Tinrec also reminds users to respect copyright for online videos.
4. Leverage post-processing features: Converting to text is just the first step. Tinrec's AI summaries and Q&A help you quickly grasp key points—don't treat the tool merely as a transcript generator.
5. Try before you buy: If unsure which tool fits, start with free plans or trials. Tinrec's free version lets you experience the full transcription and organization workflow.

Conclusion

There are many Cantonese speech-to-text tools available, but to find a free yet sufficient option, you need to clarify your needs: is it simple transcription, or do you need summaries, Q&A, and other post-processing?

If you want a one-stop solution for recording, transcription, summarization, and export, I recommend trying Tinrec first. Its free quota is enough to experience the full features before deciding on an upgrade.
