6 Free AI Speech-to-Text Tools Tested in 2026: Which Offers the Best Free Tier and Cantonese Recognition?

Choosing a free AI speech-to-text tool isn't about comparing which feature list is longest—it's about answering three questions first: How many recordings do you need to transcribe per day? Are your recordings in Cantonese, Mandarin, or a mix of Chinese and English? Do you need a verbatim transcript, or meeting minutes you can send out directly?

Get any of these wrong, and your free tier will run out fast: a few recordings and you're at the limit, and you'll end up paying anyway. Below are 6 options, organized by three dimensions: whether the free tier is sufficient, how well Chinese is recognized, and what you can do after transcription, so you can find your match.

Why You Need Free AI Speech-to-Text

Meeting notes, classes, interviews, video subtitles—all are the chore of "listening back to what was said." Manually transcribing a 1-hour recording can take 3 to 4 hours, constantly pausing and rewinding, and your focus quickly fades.

Now AI speech recognition (ASR) can produce a draft in minutes, automatically adding punctuation, paragraphs, and even generating subtitle files with time codes. This article covers 6 options with free tiers, from "occasional transcription" to "daily meetings and team knowledge retention," and finally how to choose.

Option 1 | Tinrec — The Most Complete AI Recording Assistant

One-sentence positioning: Tinrec doesn't just turn sound into text; it turns meetings into searchable, collaborative, actionable data.

Highlight 1: Desktop version records online meetings without a bot. When hosting a Zoom, Google Meet, Microsoft Teams, or Webex meeting, the most awkward thing is pulling in a meeting bot that everyone sees. Tinrec's desktop version directly captures system audio, no extra participant needed, and you can record and get a transcript as the meeting starts.

Highlight 2: The workflow after transcription is the key. Besides the transcript, Tinrec automatically generates AI summaries, chapters, key points, and action items, and you can even ask AI questions directly about the meeting content, such as "What were the three concerns the client mentioned in this meeting?" No need to listen from the beginning again—this is the biggest difference from ordinary transcription tools.

Highlight 3: Chinese, mixed Chinese-English meetings, and real-time translation. During recording, you can view the original text, translation, or bilingual comparison, so cross-language meetings don't require waiting for a translator; teams can also maintain a glossary of common terms to improve recognition of specialized vocabulary.

Highlight 4: Team space retains meeting assets. The team version is a separate space, not a few people sharing one account: meeting data belongs to the team, you can manage members, roles, and seats, view usage trends, check audit logs, and there's an audio recycle bin. If a colleague leaves, the data doesn't go with them.

Free/Paid Plans: The free version has a basic quota, allowing you to try recording, importing, summaries, and transcription; for short-term intensive use, you can choose a weekly pass; for steady use, choose a Pro monthly or annual plan. The team version's first eligible trial is 7 days, 1 free seat, 300 minutes of team shared import quota; monthly payment USD 29.80 per paid seat per month, annual payment USD 199 per paid seat per year (about USD 16.58 per month), each paid seat gets 2,000 minutes of team shared import quota per month; under an active team plan and seats, real-time recording currently does not deduct minutes. Actual prices are subject to the official purchase page.

Who it's for: Professionals who have daily meetings and need to submit minutes afterward; teams that want to centralize meeting data and need member and usage management.

Option 2 | cSubtitle — Online Transcription Focused on Chinese

Positioning: A cloud tool that requires no registration or app installation, just upload a file for instant transcription, specifically trained for Mandarin Chinese.

Highlights: Supports MP4, MOV, MP3, WAV, M4A, OGG, WMA formats, single file up to 4GB and 5 hours; text is automatically punctuated and paragraphed, and besides text files and Word transcripts, it automatically generates .srt and .vtt subtitle files with timelines, suitable for adding subtitles to videos, and also supports batch processing.

Free/Paid: Divided into free and professional versions; the free version has a quick conversion quota, the professional version allows viewing history, etc. Details are on the official website.

Who it's for: People who occasionally need to add subtitles to videos or convert Chinese recordings into usable subtitle files.

Option 3 | MyEdit — Multilingual Transcription with Daily Free Credits

Positioning: An online AI speech-to-text tool that offers free quota through daily login credits.

Highlights: Supports 9 languages including Chinese, English, Japanese, and can output plain text .txt or subtitle .srt; after generation, you can freely edit the transcript, choose whether to include timestamps, and the official statement says generated content can be used for commercial purposes.

Free/Paid: Log in daily to use credits for free transcription; upgrading to Audio Pro gives you 360 credits per month and unlocks other AI audio editing tools.

Who it's for: People who only need to transcribe one or two short recordings per day and don't want to pay for sporadic usage.

Option 4 | TurboScribe — Cost-Effective for Long Files and Batch Transcription

Positioning: A document transcription tool focused on long files, batch uploads, and subtitle translation.

Highlights: The free version allows 3 files per day, up to 30 minutes per file; after payment, single files can be up to 10 hours or 5GB, and you can upload 50 files at once, suitable for long meetings, podcasts, and class recordings. Supports subtitle and translation output.

Free/Paid: Free 3 files per day; Unlimited annual payment USD 120, about USD 10 per month.

Who it's for: People who have a bunch of long recordings to clear at once and don't need real-time meeting features.

Option 5 | Notta — Multilingual Meeting Transcription and Team Permissions

Positioning: A tool covering multi-platform transcription, meeting notes, document import, and translation, with team plans offering role permissions and usage reports.

Highlights: Strong multilingual capabilities, supports multi-device use and team management, suitable for cross-language teams.

Free/Paid: Free version has 120 minutes per month, up to 3 minutes per content; Pro annual payment about USD 8.17 per month, 1,800 minutes per month; Business annual payment about USD 16.67 per seat per month, offering unlimited transcription, role permissions, and usage reports.

Who it's for: Teams that handle multilingual meetings and also need team permissions and usage reports.

Option 6 | inFin — A Completely Free Voice Note Option

Positioning: A voice note app for both phone and computer, free and no registration required.

Highlights: After recording, you can one-click ask AI to organize into summaries, meeting notes, class key points, and to-dos, so you don't have to take notes yourself during meetings or classes.

Free/Paid: Free to use, relatively generous compared to similar tools' free trial quotas.

Who it's for: People with zero budget who just want a quick note draft. Note that its recognition accuracy is average, so it's best to check the output yourself.

With So Many Free Options, How Should You Choose?

• Want the most complete AI features (transcription plus AI chat query plus automatic minutes) → Tinrec, one of the few options that has all of these. • Host Zoom, Meet, or Teams meetings and don't want to pull a bot into the meeting → Tinrec desktop version, directly captures system audio. • Need accurate Chinese and mixed Chinese-English, plus bilingual comparison → Tinrec, supports real-time translation and team glossary. • Need to switch between phone and computer, and submit reports after meetings → Tinrec, available on iOS, Android, and web, can export to Notion, Google Docs, etc. for further processing. • Want to build a unified meeting database for the team, manage members and usage → Tinrec team version, with space, roles, seats, usage analytics, and audit logs. • Only need to occasionally transcribe a Chinese recording and add subtitles → cSubtitle or MyEdit. • Need to clear a large number of long recordings at once → TurboScribe. • Zero budget, just want a note draft → inFin.

4 Things to Know Before Using Free AI Speech-to-Text

1. Free quotas are mostly measured in minutes, not unlimited. Common practices are 120 to 300 minutes per month, or only 3 minutes per session, 3 files per day. If you use it frequently, you'll hit the limit quickly, so calculate how many minutes you need to transcribe per month before choosing a plan.

2. Chinese and Cantonese are the dividing line. Many tools focus on English meetings, and performance on Chinese and mixed Chinese-English varies greatly. Before formal use, it's recommended to test with a real recording of your own.

3. Recording quality determines accuracy. No tool should promise a fixed accuracy rate; background noise, accents, and multiple people speaking at once all affect results. The correct approach is to use a transcript with time codes and playback the recording, verifying important content yourself.

4. Handle legal and privacy issues before recording. Laws in Hong Kong and many places require obtaining consent from participants before recording, and companies may have internal policies. It's safest to clarify before the meeting.

Conclusion

Free AI speech-to-text tools aren't hard to find; the hard part is choosing one that you'll actually use after transcription. If you only occasionally transcribe a recording, the free tiers of cSubtitle, MyEdit, or inFin are sufficient; but if you have daily meetings, need to produce minutes, track action items, and even retain meeting data for the team, Tinrec's completeness is clearly a notch above—from bot-free online meeting recording to AI Q&A, action item extraction, and team space, all designed around what you need to do after the meeting. You can start with the free tier, test with one or two of your own real meeting recordings, and then decide.
