2026 Comparison of 4 Cantonese Voice-to-Text Apps: Which Handles Mixed Chinese-English and Formal Conversion Best?

Why Are Cantonese Voice-to-Text Tools Often Not Enough?

When converting Cantonese recordings to text, two issues are most common: first, too many colloquial terms like "喺" (at), "唔使" (no need), and "即刻" (immediately) make transcripts hard to read; second, mixed Chinese-English sentences like "This Proposal's Deadline is next Wednesday" might be misrecognized as gibberish, making corrections even more time-consuming. Additionally, meeting, class, or interview recordings are often long, and if the tool only provides a raw transcript, you still have to manually summarize the key points.

In this test, I tried four apps that focus on Cantonese voice-to-text: Tinrec (秒聽錄音), SoundType AI, Notely Voice, and iPhone's built-in transcription feature. I compared recognition accuracy, formal language conversion, free tiers, and post-processing capabilities. If you're looking for a tool that truly reduces organizing time, this article should give you some insights.

Tinrec vs. the Other 3 Tools: What's Different in Core Experience?

Cantonese Recognition and Mixed Chinese-English Handling

This is the most important aspect for Cantonese users. Tinrec supports automatic recognition of 10 languages, including Cantonese. In tests, it accurately captured English words in mixed sentences like "This Proposal's Deadline is next Wednesday," reducing homophone errors. SoundType AI users report a Cantonese conversion success rate of about 85-90%, but the trial is only 8 minutes, which is insufficient for long recordings. Notely Voice takes an offline approach with decent accuracy but excels at converting colloquial speech to formal language. iPhone's built-in transcription tends to be verbatim, preserving colloquial terms, and occasionally makes errors with mixed Chinese-English. In summary: if you often deal with mixed Chinese-English, Tinrec's language recognition will save you more effort.

Formal Language Conversion

Notely Voice's highlight is automatically converting "唔使" to "無需" (no need) and "喺" to "在" (at), which is convenient for those who directly paste into reports or emails. Tinrec doesn't emphasize formal conversion, but its AI summaries and chapter organization help you quickly turn spoken content into structured notes. iPhone's built-in transcription preserves colloquial language as-is, suitable for those who want a faithful archive. So if you need highly readable formal documents, Notely Voice and Tinrec each have strengths; if you want both a verbatim transcript and post-processing, Tinrec is more comprehensive.

Free Tiers and Trial Barriers

Tinrec offers a free version with monthly basic transcription credits, allowing you to try live recording, file transcription, and online video parsing, which is good for testing before paying. SoundType AI's free trial is often reported as only 8 minutes, which is unfriendly for testing long meetings or class recordings. Notely Voice is open-source and free, but you need to download models yourself, and it relies on local processing, so phone performance affects speed. iPhone's built-in transcription has no extra cost, but it only transcribes text without summaries or Q&A. If you don't want to spend money upfront, Tinrec's free plan has a relatively reasonable barrier.

Post-Processing Capabilities

This is what I value most. Tinrec doesn't just transcribe; it also provides AI summaries, chapter organization, to-do extraction, and even lets you ask questions about the recording, like "What was the meeting conclusion?" or "Who is responsible for what?" SoundType AI has AI summaries but fewer other features. Notely Voice only does transcription and formal conversion. iPhone's built-in has no organization features at all. So if your goal is to have usable notes or to-dos right after recording, Tinrec is the only one among these four that can do it end-to-end.

Tinrec's Core Features at a Glance

Real-Time Recording to Text: Open Tinrec, and text appears simultaneously as you record, with low latency. During meetings, you can confirm if you've missed any points while recording, and the transcript is ready the moment the meeting ends.

Upload Audio or Video for Transcription: Drop in existing MP3, M4A, or MP4 files, and it automatically converts them to text and generates a summary. Great for organizing past class recordings, interviews, or podcasts.

Online Video Link to Text: Paste a public video link from YouTube, Bilibili, or Xiaohongshu, and Tinrec extracts the text and key points, saving content creators or researchers a lot of viewing time.

AI Conversational Query: This is my most-used feature. After recording a one-hour meeting, I can ask Tinrec, "What was the meeting conclusion?" or "What are the action items?" It answers based on semantic understanding, so I don't have to manually go through 30 pages of transcript.

Multi-Format Export and Further Generation: You can export to Notion, Google Docs, and other tools, or even have AI generate meeting minutes, reports, or tables based on the recording, turning audio into truly usable deliverables.

Real-World Use Cases

Workplace Meetings: Use Tinrec for real-time transcription during meetings, then use AI summaries and to-do extraction to quickly organize action items. Compared to just recording or transcribing, it saves time re-listening and manually organizing.

Classes and Lectures: Students can use Tinrec to convert professor lectures into text, then use chapter organization to segment key points, making review easy by searching keywords instead of listening from start to finish.

Interviews and Research: Journalists or researchers can upload interview recordings to Tinrec to get transcripts automatically, then use AI Q&A to quickly find key data or viewpoints mentioned by interviewees, with timestamps for verification.

Content Creation: Podcasters or YouTubers can paste video links of past episodes into Tinrec to generate transcripts, summaries, and subtitle materials, facilitating secondary creation or SEO organization.

Key Points to Consider When Choosing a Voice-to-Text Tool

• Language Support: First, check if it supports Cantonese and handles mixed Chinese-English. Tinrec supports 10 languages including Cantonese, Chinese, and English, and performed stably with mixed sentences in tests.
• Free Plan Credits: Is the free version sufficient for testing? Can you upload files? Tinrec's free version provides basic credits and allows trying multiple input sources, suitable for a trial.
• Post-Processing Features: A raw transcript isn't enough; look for summaries, to-dos, and Q&A. Tinrec's AI summaries and conversational queries save a lot of manual work.
• Cross-Platform and Export Formats: Can you record on your phone, upload on your computer, and export to your commonly used tools? Tinrec offers iOS, Android, and web versions, with multiple export formats.
• Privacy and Data Handling: If privacy matters, check whether the tool uploads to the cloud. Tinrec requires internet, but you can review its privacy policy; Notely Voice focuses on offline, each with trade-offs.

Conclusion: Is Tinrec Worth Trying?

If you need more than just "turning Cantonese recordings into text"—you want to quickly grasp key points, generate to-dos, or even create meeting minutes—Tinrec is the most feature-complete among these four, with noticeable advantages in mixed Chinese-English recognition. Its free plan has a low barrier, so I recommend downloading it and testing with your own recordings, especially in your common scenarios. Notely Voice suits those who want offline formal conversion; iPhone's built-in is fine for simple archiving; SoundType AI's 8-minute trial isn't enough for me, but it might work if you only need short recordings. Overall, using "efficiency after recording" as the standard, Tinrec better meets the needs of most office workers and students.
