Turn recordings into transcripts and summaries in minutes
Upload audio or video for multilingual transcription, AI notes, and action items
Recently, I needed to turn an online English course into notes. In the past, this meant constant pausing and manual typing, leaving me with a headache before I even finished. Then I tried both Tinrec and Otter.ai, and found they can both convert English speech to text, but their underlying logic is very different—one is a "meeting bot," the other is an "audio/video knowledge workbench." From my hands-on experience, this article walks you through the full process of using Tinrec for English speech-to-text, while highlighting the differences with Otter.ai, so you know which one suits you.
Before You Start｜What You Need
- A smartphone or computer (Tinrec offers iOS, Android, and Web versions with automatic sync between devices)
- Download the Tinrec app and create an account (sign in with Google or Apple ID; the free version includes basic transcription minutes)
- An English audio content you want to transcribe—could be meeting recordings, course audio, interview recordings, or a YouTube English video link
- A stable internet connection (real-time transcription requires internet; for offline use, download the English language pack first)
Step 1｜Record the English Content You Want to Transcribe
The goal here is to get a clear English audio recording, which is the foundation for all subsequent steps.
Open Tinrec, tap the record button on the main screen, and start. When recording, keep the device close to the speaker—the closer, the clearer, and the higher the transcription quality. For one-on-one interviews, place the phone between the two people; for multi-person meetings, put it in the center of the table.
Why care so much about recording quality? Because AI transcription's limit is the audio file's limit—no matter how powerful the engine, it can't do much with a blurry mess of sound. Rather than spending time proofreading later, it's better to spend 10 seconds checking the microphone position while recording.
When done, the main screen of Tinrec will show the recording file with its length and size, and you can play it back anytime.
(Illustration: In a meeting room, a phone is placed in the center of the table recording an English discussion, with real-time transcript text appearing on the screen, participants focused.)
Step 2｜Let AI Generate a Transcript
Your recording is now an audio file; to turn it into editable text, pass it to AI for transcription.
In Tinrec, after recording, transcription starts automatically. You can also select an audio file from the library and tap "Transcribe." It supports common formats like mp3, wav, m4a, and can even parse English audio from YouTube links by pasting the URL.
The key here is that Tinrec not only outputs text but also automatically adds punctuation and paragraphs—especially important for long English passages, so it doesn't read like a wall of text without periods.
After transcription, you'll see a timestamped transcript. Tap any sentence to play audio from that point, making it easy to verify.
(Illustration: On a laptop screen, the left side shows the waveform of a playing English interview, the right side shows the transcribed English transcript, clean and properly punctuated.)
Step 3｜Quickly Proofread the Transcript
AI transcription accuracy is already high, but with background noise, heavy accents, or technical terms, small errors can slip through. Instead of listening from start to finish, Tinrec's design speeds up proofreading.
In Tinrec's editor, you can listen and edit simultaneously: tap an incorrect word, the audio jumps to that timestamp, and you fix it immediately. This saves at least half the time compared to the traditional "pause, type, replay" flow.
Another method I often use is the "AI Q&A" for proofreading—if there's an unclear term in a passage, just ask Tinrec: "What proper noun is mentioned here?" It will suggest based on context, and you can replace the text with one tap.
After proofreading, the transcript becomes reliable material ready for the next step.
(Illustration: A user taps on a word in the transcript on a tablet, and a small window pops up playing the corresponding English audio. The interface is clean and intuitive.)
Step 4｜Let AI Generate Meeting Minutes or Study Summaries
Once you have the English transcript, the real value is turning it into actionable material. Tinrec's "AI Summary" feature automatically extracts key points, action items, and section headings from long English content.
For example, with this English course recording, I selected "Generate Summary" and within seconds got a structured note: an overall summary at the top, then chapter headings, and finally three key concepts to review. This summary can also be sent to AI for further processing—like converting to a table or translating into Chinese.
Stop organizing recordings by hand
Upload audio or video and automatically get a transcript, summary, and action items
Unlike Otter.ai, whose summaries are more meeting-oriented (participants, discussion topics, action items), Tinrec offers more flexibility—whether it's a meeting, course, or interview, you can produce the format you need with the same workflow.
(Illustration: On the screen, the left side shows a dense English transcript, the right side shows an AI-generated structured summary with cards for highlights, to-dos, and chapters, visually clean.)
Step 5｜Export and Share
For organized material to be truly useful, it must fit into your existing workflow. Tinrec supports export to plain text, PDF, Word, subtitle files, and can sync directly to Notion, Google Docs, or OneNote.
Personally, I export course summaries to Notion and integrate them with previous notes; meeting minutes I convert to PDF and email to the team, along with a link to the original recording for reference. All these actions are done within Tinrec, without switching between multiple apps.
(Illustration: The same English transcript is being exported in multiple format icons to Notion, Google Docs, PDF, with arrows pointing to different cloud service logos.)
Frequently Asked Questions
Q: Can Tinrec recognize English with different accents? A: Yes, Tinrec's AI model is trained on multiple accents—American, British, Indian English, etc. If you encounter particularly heavy accents, enable "Emphasize voice" mode in settings before recording to improve recognition. Compared to Otter.ai, which has strong English recognition but struggles with non-mainstream accents or mixed Chinese-English scenarios, Tinrec's flexible adjustment options are more practical.
Q: What if the transcript has many errors? A: This is usually due to a noisy recording environment or too much distance from the speaker. Tinrec has built-in noise reduction—enable it in settings before recording. For already recorded files, after importing, you can manually select "High noise environment" mode, which is uncommon in most transcription tools.
Q: Can I transcribe English from videos? A: Yes, Tinrec supports pasting links from YouTube, Bilibili, and other public video platforms. It extracts the audio track and generates a transcript, plus an AI summary. This feature in Otter.ai requires an upgrade to the Business plan to be fully functional.
Q: How long can I use the free version? A: Tinrec's free version provides a monthly base of transcription minutes, enough to try out a couple of meetings or a few classes. Otter's free version offers 300 minutes per month, which seems more but is limited to meeting scenarios; Tinrec's free version works with file uploads and online videos, making it more cost-effective for those who like to organize various English content.
Advanced Tips｜3 Ways to Double Tinrec's Efficiency
Turn English YouTube Videos into Study Notes
Paste the video link, Tinrec automatically generates a transcript and summary. Then use AI Q&A to ask: "What is the core argument of this video?" It will answer directly from the video content, saving time compared to slowing down and rewatching. Otter can't do this—it only handles live meetings, not web videos.Seamless Multi-Device Continuity
Record on your phone, proofread on a tablet, export on a computer—all data syncs in real-time. Sometimes I record an English idea on my phone during my commute, then open the web version at the office to continue editing, no cables or file conversion needed. Otter also supports multiple devices, but its sync logic is meeting-room-centric, unlike Tinrec which suits mobile personal workers.Handle Mixed Chinese and English
Many English meetings or courses include Chinese explanations. Tinrec can recognize both Chinese and English simultaneously and produce a bilingual comparison note during the summary stage. This is something pure English tools like Otter can't do—they only transcribe English, and you have to translate later.
If You Don't Use Tinrec, Here Are Alternatives
- Otter.ai: Strong in auto-joining online meetings, real-time transcription, and team collaboration, suitable for business teams focused on English meetings. But it's weaker with classroom recordings, web videos, or mixed Chinese-English content, and the free version has narrower import channels.
- Notta: Offers comprehensive multi-language transcription and translation, but at a higher price and leans toward one-time transcription, lacking Tinrec's subsequent Q&A and organizational flexibility.
Overall, if the English content you need to process goes beyond meetings to include courses, interviews, YouTube videos, or if you want to continue asking questions, summarizing, and exporting to your favorite note-taking app after transcription, Tinrec is the more fitting choice for personal knowledge workflows.
Conclusion
With these 5 steps, you can now turn any English recording, audio file, or video into structured, searchable, and organizable text. From recording to transcription, proofreading, summary generation, and export to your preferred note-taking tool—all without jumping between multiple apps. Next step: Download Tinrec's free version, try it with your own English content—whether it's meeting minutes or online courses, you'll find that organizing English material can be this effortless.
