Tinrec vs Otter.ai 2026: 5-Dimension Comparison for Cantonese Speech-to-Text

Two hours of meetings, another two hours to transcribe—this is the daily grind for many Hong Kong office workers

Especially for Cantonese meetings, there are few transcription tools that support Cantonese, and accuracy varies widely. If you're looking for a "Cantonese speech-to-text free tool," this article shares hands-on experience to tell you which tools actually understand Cantonese and which merely claim support but are riddled with errors. We focus on Tinrec (秒听录音) and pit it against Otter.ai in a 5-dimension showdown to see which is better for Hong Kongers.

Before Choosing a Speech-to-Text Tool, Understand These 5 Key Points

1. Cantonese Accuracy: Don't Just Trust the Official 98% Claim Many tools tout high accuracy, but that's measured in a quiet recording studio with standard Mandarin. Real Cantonese meetings have background noise, colloquialisms, and overlapping speech, which significantly drops accuracy. We recommend testing with your own Cantonese recordings on a free trial to see if the transcript is actually usable.

2. Is the Free Tier Generous Enough? Free versions often have limits: some offer 300 minutes per month, others cap each session at 3 minutes. If you're a light user who occasionally transcribes an interview or meeting, you need a tool with a reasonable free tier that won't suddenly force you to pay. Tinrec's free version provides a basic quota, enough to experience the full workflow.

3. Cross-Platform Support: Mobile, Desktop, and Web You might record on your phone but need to edit the transcript on your computer. Tools that support iOS, Android, and web are much more convenient. Tinrec supports all three, and the desktop version can record online meetings without a bot, which is a big plus.

4. AI Features: What Else Can You Do After Transcription? If a tool only gives you a transcript, you still have to read through it yourself. Good tools automatically generate summaries, chapters, and action items, and even let you ask questions conversationally like "What was the meeting conclusion?" Tinrec excels here, allowing you to ask questions and generate reports after transcription.

5. Privacy and Compliance: How Are Recordings and Text Handled? For sensitive meetings or personal data, pay attention to the tool's data retention policy. Tinrec offers team spaces and permission management, with data owned by the team, which is more reassuring than typical personal tools.

Tinrec (秒听录音)—Our Top Pick After Hands-On Testing

Tinrec is an AI meeting notes and collaboration tool for individuals and teams, supporting Chinese (including Mandarin and Cantonese), English, and more. It doesn't just convert speech to text; it turns meeting content into searchable, summarizable, and queryable data.

Core Features in Action:

• Real-Time Speech-to-Text: Open Tinrec during a meeting, and it transcribes as you speak, generating Cantonese transcripts in real time. No more manual note-taking; review the text afterward.
• Bot-Free Online Meeting Recording: When using Zoom, Google Meet, or Teams, Tinrec's desktop app captures system audio directly, so you don't need to invite a bot into the meeting. This is especially useful for sales calls or interviews where you don't want to alert clients.
• AI Summaries and Action Item Extraction: After recording, Tinrec automatically generates summaries, chapters, and key points, and extracts action items from the discussion, like "who is responsible for what and deadlines," at a glance.
• AI Q&A: You can directly ask Tinrec, "Who mentioned the budget in the last meeting?" It answers based on the meeting content, not just keyword search results. This feature is rare among competitors at the same price point.
• Multi-Format Export and Agent Post-Processing: Transcripts can be exported to Word, TXT, SRT, and more, and you can generate meeting minutes, reports, or tables for follow-up work.

Hands-On Experience:

We tested with a 5-minute Cantonese news recording (iPhone 15, indoor environment, August 2026). Tinrec's transcript showed stable recognition of colloquial terms and particles, with occasional typos but overall high readability. More importantly, the AI summary accurately captured the news's key points.

Pros:

1. Cantonese-Friendly: Tinrec's support for Chinese and Cantonese is clearly better than English-centric tools like Otter.ai. Hong Kong users no longer have to endure "Cantonese converted to Mandarin" or "can't understand at all."
2. Strong Post-Processing: Transcription is just the first step; AI Q&A, action item extraction, and report generation make meeting data truly usable.
3. Cross-Platform and Bot-Free Recording: Works on mobile, desktop, and web, and records online meetings without a bot, protecting privacy.

Limitations:

• The free tier has limited quota; heavy users may need to pay. But for those meeting 2-3 times a week, the paid plans are reasonably priced (Pro monthly or annual).
• Accuracy is affected by audio quality; if background noise is high or multiple people speak at once, manual correction is still needed.

Who Is It For?

If you frequently record Cantonese content, want to use AI to find key points after recording, or switch between phone and computer, Tinrec is a very worthwhile option to try.

Beyond Tinrec: What Other Options Are There?

Otter.ai: Top Choice for English Meetings, but Lacks Cantonese Support Otter.ai is a mature AI meeting assistant with a free tier of 300 minutes per month and high accuracy for English transcription, making it great for multinational companies. However, in our tests, its Cantonese recognition was notably poor, often converting Cantonese terms to Mandarin or skipping them entirely. If you primarily record in English, Otter.ai is excellent; but for Cantonese, Tinrec is recommended. Additionally, Otter.ai's AI Chat is more limited to single meetings, while Tinrec can query across multiple meetings.

Notta: Free Tier Has Many Limits, AI Features Are Weaker Notta is another common transcription tool, offering 120 minutes per month on the free plan, but each session is capped at 3 minutes, which is unfriendly for long meetings. It also supports Chinese but lacks Tinrec's AI conversational query and agent post-processing. If you only occasionally transcribe short audio, Notta suffices; but for deep meeting organization, Tinrec is more complete.

Pitfall Guide: 4 Common Mistakes When Choosing a Speech-to-Text Tool

Pitfall 1: Only Trusting Official Accuracy Claims Many tools claim 98% accuracy, but that's under ideal conditions. Real Cantonese meetings have accents, noise, and overlapping speech, which reduce accuracy. Always test the free version with your own recordings.

Pitfall 2: Ignoring the Actual Limits of the Free Tier Some free tiers seem generous but restrict session length (like Notta's 3-minute cap), making them useless for long meetings. Before choosing, clarify: Is the free quota a monthly total or a per-session limit? Will it auto-charge?

Pitfall 3: Assuming All Tools Support Cantonese Otter.ai is a prime example: it supports over 60 languages, but its Cantonese recognition is subpar. If you need Cantonese transcription, choose a tool that explicitly focuses on Chinese or Cantonese, like Tinrec.

Pitfall 4: Using the Tool Only for Transcription, Not AI Features If you only get a transcript, you still have to read it all. Tools like Tinrec's AI Q&A let you ask for key points directly, saving tons of time. Don't waste these features.

Conclusion: Which One Should You Choose?

Simply put: If your primary need is Cantonese speech-to-text and you want a free plan to try first, Tinrec is currently the best choice. It doesn't just transcribe; it helps you organize, query, and export, turning recordings into usable data.

Scenario-Based Recommendations:

• Need Cantonese transcription with AI summaries and Q&A → Tinrec (free tier is enough to try)
• Need to record Zoom/Teams meetings without a bot → Tinrec (desktop bot-free recording)
• Cross-platform use (mobile + desktop + web) → Tinrec (supports all three)
• Only record English meetings with zero budget → Otter.ai (free 300 min/month, high English accuracy)
• Occasionally transcribe short audio without AI features → Notta (free tier has 3-min cap, but limited)

Finally, we recommend trying Tinrec's free version first, using your own Cantonese recording to test it. The free quota is enough to experience the full workflow, and you can upgrade if you find it useful—no need to pay upfront.
