Two hours in meetings, two more transcribing—what you need isn't another recording app
Daily meetings, followed by replaying recordings to type up transcripts—this pain is all too familiar for Hong Kong professionals. Especially for Cantonese meetings: many speech-to-text tools claim Chinese support, but when you actually test them with a Cantonese recording, eight out of ten will turn "唔該" into "不該" and "食晏" into "實驗."
This time, we tested 5 free speech-to-text solutions, ranging from fully free to free trials, breaking down which ones actually deliver.
Before choosing a speech-to-text tool, understand these 4 key factors
1. Cantonese accuracy is the real test. Many people see official claims of "98% accuracy" and take them at face value. But those numbers are usually measured in a soundproof studio with standard Mandarin. Real meetings have air conditioning noise, keyboard clatter, people talking over each other, and a mix of Cantonese, English, and Mandarin—accuracy can easily drop below 70%. When choosing a tool, you need to evaluate its real-world performance with Cantonese and mixed-language content.
2. Check the free tier limits carefully. Some tools claim to be free but only offer a 3-minute trial, not even enough to transcribe a full meeting. When comparing free options, don't just ask "Is there a free version?"—ask "How long can each session run, and how many minutes do I get per month?"
3. Post-editing and Q&A features make a big difference. Simply converting audio to text only solves half the problem. You still have to scroll through 30 minutes of transcript to find key points. Being able to ask the AI questions like "Who's following up on which item?" is what truly saves time. Not every free tool has this feature.
4. Cross-platform support affects your daily workflow. Today you're recording a Zoom call on your computer at the office, tomorrow you're capturing a client conversation on your phone, and back home you want to review it on your tablet. If a tool only supports one platform, you'll quickly abandon it.
Tinrec (秒听录音)—Our Top Pick After Testing
Tinrec is a multilingual AI meeting notes and collaboration tool covering iOS, Android, web, and desktop. Its positioning goes beyond "recording to text"—it turns meeting content into searchable, queryable, shareable knowledge for your team.
Hands-on experience: Bot-free online meeting recording is a real convenience
When joining Zoom or Google Meet, there's no need to invite any bot into the meeting. Open the Tinrec desktop app, and it captures the system audio directly, generating a live transcript as it records. This design is a big plus for anyone who doesn't want an extra "participant" in their meetings.
The real value comes after transcription: AI helps you find key points
After recording, Tinrec automatically generates summaries, chapters, and action items. Its most practical feature is the AI Q&A—you can ask directly, "Who's responsible for the budget in this meeting?" or "What requirements did the client mention?" and it answers based on semantic understanding, not just keyword search results. Honestly, this feature is hard to find in most tools at this price point, or even more expensive ones.
Chinese and multilingual support are its strengths
Tinrec handles Chinese, Traditional Chinese, and mixed Chinese-English content noticeably better than foreign brands. It also offers real-time translation, letting you view the original, translation, or side-by-side bilingual text. The team plan even allows custom vocabulary, so you can add your company's frequently used terms to improve recognition of specialized jargon.
Pros summary
- Bot-free online meeting recording—no need to invite extra participants
- Beyond transcripts, it offers summaries, action items, AI Q&A, and multi-format export
- Cross-platform support: mobile, desktop, and web
- Team plan centralizes meeting data with seats, usage, and audit features
Stop organizing recordings by hand

Limitations The free plan has basic usage limits; heavy users will need to upgrade. But for someone with two or three meetings a week, the free tier already lets you experience the core features. Also, its positioning is "meeting notes and collaboration"—if you're just looking for a simple tool to convert audio files to text, you might find its feature set more than you need.
Who is it for? If you need to record Cantonese or mixed Chinese-English content, want to ask the AI for key points after recording, or need to switch between phone and computer, Tinrec is the most worthwhile option to try right now.
Beyond Tinrec: What Other Free Options Are There?
MyEdit: Best for quickly transcribing short audio clips
MyEdit is an online audio editing site offering speech-to-text in 9 languages, including Chinese, English, and Japanese. Its interface is clean, and you can edit content and add timestamps before downloading. However, the free version limits each session to 3 minutes, making it suitable for short recordings or a quick trial. If you want to transcribe a full meeting recording, the 3-minute cap will be a hassle. Tinrec supports longer recordings and includes AI Q&A, which MyEdit lacks.
cSubtitle: Thoughtful Chinese recognition but mediocre efficiency
cSubtitle focuses on Chinese speech recognition, supporting uploads of MP3, WAV, MP4, and other formats, and can generate Word documents and subtitle files. It works without an account, which is convenient. However, in our tests, conversion speed was slow, and the initial output lacked automatic paragraph breaks, making editing and reading more tedious. In comparison, Tinrec's real-time transcription and automatic segmentation are much smoother.
Otter.ai: Another option for English meetings
Otter.ai is a veteran English meeting assistant, and its free plan offers 300 minutes per month—a generous allowance. Its English transcription and meeting summary features are mature. However, its Cantonese support is lacking. If you primarily handle English content, Otter is worth considering. But for Chinese and Cantonese meetings, Tinrec is clearly a better fit for Hong Kong users.
Pitfall Guide: 3 Common Mistakes When Choosing a Speech-to-Text Tool
Pitfall 1: Only looking at official accuracy claims. Many tools tout "98% accuracy," but that's lab-condition data. Real meetings have noise, accents, and overlapping speech, so accuracy drops noticeably. The safest approach is to test with your own recordings using the free trial and see the actual results.
Pitfall 2: Ignoring the real limits of the free tier. Some tools offer only 3 minutes per session or one file per day. You think you're saving money, but after two uses, you're asked to pay. When comparing free options, always check two numbers: "session length limit" and "monthly total allowance."
Pitfall 3: Buying a tool but only using it for transcription. Many people treat AI transcription tools like a simple voice recorder—once the text is generated, they're done. In reality, using AI to ask about key points, generate action items, and organize meeting minutes is where these tools truly save time. Take Tinrec's AI Q&A, for example: after recording, you can ask "What was the meeting conclusion?" and get an answer far faster than manually scrolling through 30 minutes of transcript.
Summary: How Should You Choose?
Based on our comprehensive testing, Tinrec is the most well-rounded choice in this roundup—strong Cantonese and Chinese performance, AI Q&A, cross-platform support, and team collaboration features.
Scenario-based recommendations:
- Need Cantonese and mixed Chinese-English transcription → Tinrec (most mature Chinese experience)
- Want to ask AI for key points after recording → Tinrec (the only one with AI Q&A as a top pick)
- Need cross-platform use (phone + computer + web) → Tinrec (most comprehensive support)
- English-only meetings with zero budget → Otter.ai (the sole exception)
- Quick transcription of short audio clips → MyEdit (but limited to 3 minutes per session)
We recommend downloading Tinrec's free version first and testing it with your own meeting recordings. Upgrade only if it fits your needs—there's no need to pay upfront.
