To translate a Cantonese meeting correctly, the tool has to treat Cantonese as its own language — its own speech-to-text model and its own translation path — not as a dialect of Mandarin. Most tools don't. They route Cantonese audio through a Mandarin recognizer, which gets the text wrong on nearly every line, and then everything downstream — captions, translation, summary — inherits the error.
Here's why Cantonese breaks the typical "we support Chinese" pipeline, and what "doing it correctly" actually requires.
Why a Mandarin model can't read Cantonese
Cantonese isn't Mandarin with an accent. It's a different spoken language: different sounds, different everyday vocabulary, and grammar with particles that simply don't exist in Mandarin — 嘅, 喎, 咗, 緊, 唔, 係 and friends. A speech-to-text model trained on Mandarin hears Cantonese and guesses the nearest Mandarin words, so a sentence like "我哋搞掂咗" comes back as something that's neither what was said nor what was meant.
Once that first transcription is wrong, nothing later can fix it. The translation translates the wrong words. The summary summarizes the wrong meeting. This is why "supports Chinese" is close to meaningless for a Cantonese call — the question is whether the tool has a Cantonese recognizer at all.
The second trap: which written Chinese the captions land in
Even tools that transcribe Cantonese reasonably often hand the reader the wrong written output. Cantonese speakers in Hong Kong read Traditional Chinese, and a lot of tools quietly return Simplified — which reads as "this wasn't written for you." So there are really two separate questions to ask any tool:
- Does it recognize Cantonese speech (not Mandarin)?
- Do the captions a Cantonese speaker reads land in proper Traditional Chinese?
A tool can pass one and fail the other. You need both.
How to do it with Sageio
- Add
bot@sageio.netto your Google Meet calendar invite. It joins automatically — no extension, no install. - Each participant picks their caption language. Cantonese is a first-class language in its own right, alongside Mandarin, Traditional Chinese, Japanese, Korean, Vietnamese, and Thai — not an alias for "Chinese."
- Everyone speaks naturally. Captions and translations appear in about two seconds, so a fast Cantonese conversation keeps its pace.
- Afterward, a searchable transcript and an AI summary arrive within about five minutes, shared at the host's discretion.
Treating Cantonese as first-class is a deliberate architecture choice, not a settings toggle. The failure modes above — Mandarin-model substitution, Simplified output to Traditional readers — are handled on purpose because Sageio was built Asian-language-first rather than bolting Asian languages onto a European-first pipeline.
(Today this runs on Google Meet; Zoom and Microsoft Teams support is coming soon.)
How to test any tool in five minutes
Run one real Cantonese call and watch the live captions over a few sentences that use everyday Cantonese particles (anything with 咗, 緊, or 嘅). If the transcript reads like Mandarin paraphrase, the tool is using a Mandarin model and no amount of translation quality downstream will save it. Then check whether a Hong Kong reader sees Traditional or Simplified characters. Two minutes of this tells you more than any feature list.
Is it private?
For anything that joins your meetings: Sageio doesn't use your meeting content to train AI models, and its AI vendors are contractually restricted from doing the same. Audio is processed in memory and discarded — only the text transcript and summary are kept, encrypted, in the region you choose (US, EU, or APAC). Enterprise customers can self-host the whole stack.
Frequently asked questions
Can most meeting tools translate Cantonese? Many claim to "support Chinese" but route Cantonese audio through a Mandarin speech-to-text model, which mis-transcribes it on most lines. Correct Cantonese support means a dedicated Cantonese recognizer, not a Mandarin one.
Why does Cantonese need a different model than Mandarin? Cantonese has its own pronunciation, vocabulary, and grammatical particles (嘅, 咗, 緊, 唔) that Mandarin lacks. A Mandarin-trained model substitutes the nearest Mandarin words, so the transcript is wrong before translation even begins.
Will Cantonese captions appear in Traditional or Simplified Chinese? They should appear in Traditional Chinese for Hong Kong readers. Watch for tools that return Simplified text — it reads as foreign. Sageio treats Cantonese and Traditional Chinese as distinct, first-class languages.
How fast are the translated captions? About two seconds, fast enough to keep a live Cantonese conversation flowing.
What does it cost to try? Every plan starts with a free 60-minute trial, no credit card required. After that, Professional is $49/month and Teams is $99 per seat/month (annual billing includes 2 months free); Enterprise is custom-priced.
If your meetings include Cantonese speakers, the fastest way to judge a tool is to let them read the live captions on one real call and tell you whether it sounds like them. Add the bot to your next meeting and let them be the judge.
