How to Choose Cantonese Voice-to-Text in 2026? A 5-Step Comparison of Tinrec vs Otter.ai

Meetings day in and day out can be exhausting, but the worst part isn't the meeting itself—it's writing the meeting minutes afterward. Especially when you speak in Cantonese, most voice-to-text tools fail you—either they can't distinguish between "喺" and "係", or they turn mixed Chinese-English speech into gibberish. Today, we tested two popular tools, Tinrec (秒聽錄音) and Otter.ai, to see which one is the real lifesaver for office workers.

Tinrec vs Otter.ai | Quick Overview

Tinrec positions itself as an AI recording and audio/video organization workstation, focusing on turning meetings, courses, interviews, and online videos into searchable, organized data. Otter.ai, on the other hand, is a veteran AI meeting notes tool, excelling in English meeting transcription and team collaboration.

Below, we compare them across five dimensions to see which one suits Hong Kong users better.

Dimension 1 | Cantonese Recognition Accuracy

Otter focuses on the English market, and its Cantonese recognition has never been outstanding. It often makes mistakes with Hong Kong accents and colloquial expressions, such as "唔使" and "仲有", which easily become wrong characters. Tinrec, on the other hand, has clearly optimized for Chinese content, offering better support for Traditional Chinese and Cantonese accents. In a real test with a 5-minute Cantonese meeting recording, Tinrec's character error rate was significantly lower than Otter's, especially in environments with continuous speech and slight background noise.

→ This dimension: Tinrec clearly wins.

Dimension 2 | Handling Mixed Chinese-English

Hong Kong people often mix Chinese and English when speaking, which is the ultimate test for transcription tools. When Otter processes sentences like "呢份 Proposal 嘅 Deadline 係下週三", it easily misinterprets English words as homophones in Chinese, making subsequent corrections time-consuming. Tinrec supports mixed Chinese-English content; in tests, even with fast-paced mixed speech, it accurately captured English words, greatly reducing the pain of correcting homophones afterward.

→ This dimension: Tinrec clearly wins.

Dimension 3 | Input Source Diversity

Otter mainly focuses on online meetings, supporting automatic joining of platforms like Zoom and Google Meet, and also allows uploading audio files, but its support for online videos and local video files is weaker. Tinrec is much more comprehensive: besides real-time recording and file upload, it can directly paste links to public videos like YouTube and Bilibili for transcription. For office workers, this means no need to download and convert videos first—just paste the link and you're done, which is much more convenient.

→ This dimension: Tinrec wins.

Dimension 4 | AI Organization and Q&A

Otter has AI summaries and AI Chat, allowing you to ask about meeting content, but its features are more geared toward meetings, with average support for organizing courses, interviews, and video content. Tinrec's AI organization is more comprehensive: it automatically generates summaries, chapters, and action items, and also allows AI Q&A around the recording content, even generating meeting minutes, reports, and other deliverables. For example, you can directly ask "What issue does the client care about most?" and Tinrec will instantly find the relevant segments, saving you a lot of re-listening time.

→ This dimension: Tinrec wins (Otter's AI features are stronger for English meetings, but for Cantonese and multi-source organization, it falls short of Tinrec).

Dimension 5 | Pricing and Plan Flexibility

Otter's free version offers 300 minutes per month, and the Pro annual plan costs about US$8.33/month (approximately HK$65), which is reasonable for English users, but for Hong Kong users dealing with a lot of Cantonese content, the low accuracy effectively wastes minutes. Tinrec's free version includes a basic transcription quota, and its paid plans come in weekly, monthly, and yearly cards, offering much more flexibility than Otter. If you only use it occasionally, you can choose the weekly card for short-term projects; long-term users can opt for the yearly card for a lower monthly cost.

→ This dimension: Tinrec wins (more flexible plans, better suited to Hong Kong users' needs).

What Unique Advantages Does Each Have?

Tinrec's Unique Advantages:

• Multi-source audio/video organization: Handles meetings, courses, interviews, and online videos—all in one app.
• AI conversational queries: You can "chat" with the recording content to quickly find key points and generate action items, saving time.
• Multiple export formats: Supports third-party tools like Notion and Google Docs for easy follow-up organization.
• Optimized for Chinese content: Excellent recognition of Traditional Chinese and mixed Chinese-English, suitable for Hong Kong workplaces.

Otter's Unique Advantages:

• Strong meeting bot: Automatically joins online meetings, identifies speakers, suitable for team collaboration in English environments.
• Mature English transcription: High accuracy for English, user-friendly interface, favored by employees in foreign companies.

Summary: Who Should You Choose?

• If you need to process Cantonese recordings with frequent Chinese-English mixing → Tinrec (more stable in Cantonese recognition and English word capture)
• If you want to use AI to ask about key points and generate action items after recording → Tinrec (more comprehensive AI Q&A and organization features)
• If you often need to transcribe online videos or podcasts → Tinrec (directly paste links to convert to text; Otter can't do this)
• If you primarily have meetings in English and need team collaboration and speaker identification → Otter.ai remains the strong choice

In a nutshell: For most Hong Kong office workers, Tinrec is the more complete and time-saving choice. We recommend trying the free version first to see how it handles your recordings, then decide whether to upgrade.
