Mother Tongue is back with double the rewards and double the impact
Mother Tongue is back. Season 4 (MTS4) brings new mechanics that don’t just refine our process — they redefine how the entire DataHub works moving forward.
This isn’t just another campaign. It’s a system upgrade.
TL;DR — How to Join MTS4
- To upload, you must stake 100 PUBLIC (28-day lock).
- Speak clearly — AI checks are stricter, so quality matters.
- Rewards in USDT, amount depends on language.
- Only Judges can vote. Uploaders focus on clean recordings.
- You can switch languages anytime, but doing so forfeits any unclaimed rewards.
- Read the rules carefully before you start — mistakes can cost your stake.

What’s New in MTS4
Staking to Upload
- To upload, contributors now stake PUBLIC. (NEAR supported for now)
- Malicious activity = ban + 100% stake slashed. (Minor mistakes can still be resolved manually)
- Stakes are locked for 28 days.
Audio Submissions
- Our AI detection got sharper.
- Speak clearly, at a steady pace, with good volume.
- Expect uploads to take longer (10–20 audios won’t be as quick as before).
Language Settings
- You can now change your language directly in your profile.
- If you’re active in a live campaign (like MTS4), language stays locked until it ends.
Voting Updates
- Only Judges can vote.
Rewards
- Rewards continue in USDT.
- Different languages, different rewards.
Referrals
- The referral system is being redesigned. It’s hidden for now.
Dashboard Updates
- Your dashboard now reflects both $PUBLIC stakes and USDT rewards for uploads.
Updated Rules for Uploads
✅ Find a quiet spot with no background noise (no fans, pets, traffic, or other people talking).
✅ Wait 1 second after hitting “start” to be sure the recording is working.
✅ Speak casually, as if you’re talking to a friend, with clear pronunciation and energy.
✅ Read the words exactly as they appear, without repeating or omitting any words.
✅ Press “stop” after reading the phrase.
✅ Play the recording to confirm it’s clear and complete.
✅ Hit “skip” if the recording is bad or words are cut off, submitting bad recordings will decrease your reputation.
❌ Do NOT repeat the phrase multiple times.
❌ Do NOT use TTS or AI voice generation or your account will be banned.
MTS4 Languages
English (for Standard, Indian & Pinoy accents), French, Spanish, Mandarin, Italian, Thai, Indonesian, Russian, Arabic (Modern Standard), German, Korean, Japanese.
Why This Matters
MTS4 isn’t just about more recordings. It’s about raising the quality bar, protecting the integrity of the data, and rewarding contributors who do the work right.
Experts win. Clients win. That’s the PublicAI model.
