6 Best Audio-to-Text Tools for Cantonese in 2026: Which Free Option Is Actually Usable?

Have you ever had this experience: you have a two-hour Cantonese interview or meeting recording, and you want to turn it into text. So you search for "free Cantonese audio to text" and find a bunch of websites that look similar. You try three of them—two only recognize Mandarin, and the third hits a paywall at the 15-minute mark.

This article is here to help you avoid the two most common traps.

The first trap is mistaking "supports Chinese" for "understands Cantonese." There are many Chinese transcription tools, but tools trained primarily on Mandarin often produce disastrous results when faced with Cantonese colloquialisms, sentence-final particles, and mixed Chinese-English speech.

The second trap is the definition of "free." Some tools offer genuinely usable free tiers, while others only let you preview the first few minutes for free and charge extra for exports. Understanding this is far more important than comparing feature lists.

Below is a summary of 6 tools whose plans and pricing I've actually researched, with a priority on clarifying "can it handle Cantonese" and "how free is free."

Why Do You Need Cantonese Audio Transcription?

The demand for transcribing Cantonese content is actually quite concentrated: conference calls with Hong Kong clients, discussions among cross-border teams, recordings of Cantonese-taught courses, oral history interviews with elders, and the growing number of Cantonese podcasts and short videos.

What these scenarios have in common is that manual transcription is too slow. For a one-hour recording, pausing, replaying, and typing sentence by sentence often takes three to five times as long.

AI transcription can compress this process into minutes—provided you choose the right tool. Here are the 6 options covered in this roundup.

Tinrec (Miao Ting Lu Yin) — Turning Transcriptions into Searchable, Trackable, Deliverable Meeting Materials

Tinrec is an AI meeting notes and collaboration tool for individuals and teams. It doesn't just turn audio into text; it organizes the transcription into materials you can continue working with.

The first thing that caught my attention is that it doesn't require a "meeting bot." The desktop version directly captures your computer's system audio, so when handling online meetings on Zoom, Google Meet, Microsoft Teams, or Webex, you don't need to pull an extra bot account into the meeting room. For anyone who needs to record Cantonese client meetings, this saves a lot of hassle explaining things beforehand.

Second is the post-transcription workflow. In addition to the verbatim transcript, it automatically generates summaries, chapters, key points, and action items. You can ask AI questions about the meeting content, further generate reports, tables, and documents, or export to Notion, Google Docs, OneNote, and other tools for further processing. Real-time translation supports viewing the original text, translation, or bilingual side-by-side, which is very useful for cross-language meetings.

Third is team knowledge retention. The team version is a separate team workspace, not multiple people sharing one account. Meeting data belongs to the team, members can share and view it, and admins can manage roles, seats, usage analytics, and audit logs. When a member leaves, their data can be handed over to other active members and won't disappear with the individual. Team hotwords let you maintain commonly used professional terminology, which helps with recognition accuracy.

Pricing: The personal plan has a free version to experience basic quotas. For short-term intensive use, consider a weekly card; for steady weekly needs, choose the Pro monthly card; for long-term accumulation of recording data, choose the annual card. The team version offers a 7-day trial for first-time eligible users, 1 free seat, and 300 minutes of shared import quota; monthly billing is USD 29.80 per paid seat, annual billing is USD 199 per paid seat (about USD 16.58/month), each paid seat provides 2,000 minutes of team shared import quota per month, and real-time recording under active seats is currently not deducted by minutes.

Who it's for: People who need to start recording during the meeting, organize minutes and action items afterward, or want to turn meeting data into a team asset. If you just want to convert an existing Cantonese recording into plain text, its value lies in "what you can do after transcription."

Subanana — A Cantonese-Specific Online Transcription Tool

If your need is very simple—just "turn a Cantonese recording into a transcript"—Subanana is the most direct fit. Upload an audio file, video, or paste a public link, select Cantonese and output style (spoken or written, traditional or simplified), and AI will output a speaker-separated, punctuated transcript within minutes, handling mixed Chinese-English content as well.

Export formats are quite comprehensive: SRT, VTT, TXT, DOCX, XLSX, and Markdown are all supported. Free accounts can upload and preview the first 15 minutes of transcription for each file, no credit card required.

Note that the 15 minutes for free accounts is a "preview," and exporting files is a paid feature. It's recommended to first run a free preview on your own recording to confirm the results before deciding. Also, recordings in noisy environments or with multiple people talking over each other will still see reduced accuracy—no tool can escape that.

cSubtitle — An Online Transcription Service Focused on Mandarin Chinese

cSubtitle's process is straightforward: upload a video or audio file, no account registration required, and download the text file in as little as a few minutes. Single file limit is 4GB or 5 hours, supporting common formats like MP4, MOV, MP3, WAV, M4A, OGG, and WMA.

Output includes punctuation and paragraph breaks, and Word files come with time codes for easy proofreading by re-listening. It also generates .srt and .vtt subtitle files with timelines, which is handy for adding subtitles to videos.

But there's a keyword to note: the official description says it "focuses on Mandarin Chinese" and improves Chinese recognition accuracy through extensive Mandarin data training. So it's suitable for Mandarin content; before trying it with Cantonese recordings, it's best to verify the results and not assume it will be equally accurate.

MyEdit — A Handy Transcription Feature in a Video/Audio Editing Site

MyEdit is a comprehensive video and audio editing website that offers free speech-to-text in 9 languages including Chinese, English, and Japanese. After transcription, you can edit the content and add timestamps before exporting, which is convenient for those who need to make quick edits.

The free trial covers the first 3 minutes of each video/audio, suitable for testing with a short clip first. If you need to process a lot, there are time-based plans, e.g., 100 minutes for NT$368, 500 minutes for NT$1,476 (priced in USD, prices may fluctuate).

Before use, confirm whether Cantonese is included in the 9-language list. Language support for general-purpose tools like this changes quickly, so checking the official page before purchasing is safest.

Google AI Studio (Gemini) — Truly Free, But Requires Some Patience

Users online have shared that using Google AI Studio with Gemini for transcription shows good Cantonese recognition, supports long content, requires no extra subscription, and works on both desktop and mobile. After transcription, you can directly ask Gemini to further analyze, organize, and summarize.

The advantages of this route are low cost and high flexibility. The downside is that it's not inherently designed as an "audio-to-text" product interface; the workflow requires self-exploration, and segmentation, speaker labeling, and subtitle file output are not one-click like dedicated tools.

Suitable for those willing to spend a little time setting up and who only need occasional transcription. If your recordings are part of a team workflow, dedicated tools will save much more effort.

Notta — A Familiar Option for Multilingual Transcription and Team Plans

Notta covers multi-platform transcription, meeting notes, file import, translation, and team plans. It's a highly visible choice in the market, with multilingual support as one of its strengths.

Current official details: Free version offers 120 minutes per month, with a maximum of 3 minutes per single item; Pro annual billing is about USD 8.17/month for 1,800 minutes per month; Business annual billing is about USD 16.67/seat/month, offering unlimited transcription, role permissions, and usage reports.

The free version's "maximum 3 minutes per single item" is the most likely bottleneck in actual use—meaning a long recording must be split into many segments. If your Cantonese material tends to be long, factor this in ahead of time.

With So Many Options, How Should You Choose?

• Want to generate summaries, chapters, and action items directly after transcription, and be able to ask questions about the meeting content afterward → Tinrec, one of the few tools in this list with a complete "post-meeting workflow."
• Need to record online meetings on Zoom, Meet, Teams, Webex without inviting a bot into the meeting room → Tinrec desktop version captures system audio, so no extra participant appears.
• Meeting data needs to be available for the whole team to search and use, with seat and usage management → Tinrec team version, where data belongs to the team rather than individuals.
• Just have one Cantonese recording and want to see what the transcription looks like for free → Subanana's free preview is the most direct.
• Material is mainly Mandarin and you need complete subtitle file output → cSubtitle's .srt/.vtt workflow is smooth.
• Zero budget and willing to figure out settings yourself → The Google AI Studio with Gemini route is worth trying.
• Need to process many long files and value batch efficiency → Consider tools like TurboScribe that focus on long-file transcription, but be sure to confirm Cantonese support before purchasing.

4 Things to Know Before Using Free Cantonese Transcription Tools

1. "Supports Chinese" does not equal "supports Cantonese." This is the trap most people fall into. When choosing a tool, look directly for whether the page explicitly says "Cantonese" or "Guangdonghua." If it doesn't say so, assume it doesn't support it and verify with a short recording first.

2. Free usually means "free preview" or "free quota." Some allow viewing the first 15 minutes but not exporting; some offer a fixed number of minutes per month; some limit to 3 minutes per session. Check the limitations first before deciding whether to invest time.

3. Choose the right output to save half your proofreading time. Spoken and written Cantonese differ greatly. If your transcript is for your manager, written style will look much more presentable; if you need to preserve the original tone for interview quotes, choose spoken style.

4. Recording quality determines success—always re-listen to important content. Even the best AI will make mistakes in noisy environments, with multiple people talking over each other, or with heavy accents, and technical terms are often misheard. The correct approach is to keep a time-coded transcript like Tinrec does and replay key sections for verification. Also, recording and transcription involve personal data; handle according to local regulations and obtain consent from participants when necessary.

Conclusion

With the need for "free Cantonese audio to text," ultimately you need to ask yourself one thing: do you just want text, or do you want material you can continue to use?

If it's just text, Subanana's free preview, cSubtitle's subtitle output, and Google AI Studio's zero-cost route can all solve the immediate problem.

But if this recording represents a meeting, an interview, or a project, then the real cost is never in the transcription—it's in the organizing, tracking, and handover after transcription. That's why I recommend trying Tinrec first: it connects the transcript, summary, action items, AI Q&A, and team workspace into one workflow, so you don't have to open a bunch of windows to piece things together afterward.

The recommended approach is simple: take your own 10-minute Cantonese recording, run it through two or three candidate tools, and see which output is closest to something you can use directly. Free quotas exist for exactly this purpose.
