Accuracy Tips
Banglish requires TalkWriter Pro or Enterprise. Upgrade to Pro →
Banglish output quality depends on how well each stage of the pipeline performs. These 7 tips are ranked by importance -- start with the top and work your way down.
The 7 Tips
Tip 1: Set Your Language Manually
Importance: ⭐⭐⭐⭐⭐ Critical
This is the single most important setting. Auto language detection does not work reliably with Banglish. You must manually select your language in Settings > Language.
| Setting | Result |
|---|---|
| ❌ Auto-detect | Inconsistent -- sometimes English, sometimes wrong language |
| ✅ Bengali (manual) | Consistent, accurate Banglish output |
How to fix: Settings > Language > Speech Language > select your language
If you only follow one tip on this page, make it this one. Manual language selection is responsible for the biggest accuracy improvements.
Tip 2: Speak Clearly at a Natural Pace
Importance: ⭐⭐⭐⭐⭐ Critical
The speech recognition engine works best with clear, natural-paced speech. You do not need to speak slowly or robotically -- just avoid mumbling and speak as if you are talking to someone across a table.
| ❌ Avoid | ✅ Do |
|---|---|
| Mumbling or speaking under your breath | Speak clearly, project your voice slightly |
| Speaking extremely fast | Use your natural conversational pace |
| Speaking unnaturally slowly | Don't over-enunciate or pause between every word |
| Covering your mouth | Keep the microphone path clear |
Tip 3: Reduce Background Noise
Importance: ⭐⭐⭐⭐ Very Important
Background noise confuses the speech recognition engine, which causes errors that cascade through the entire Banglish pipeline.
Best environments (ranked):
- ⭐⭐⭐⭐⭐ Quiet room with door closed
- ⭐⭐⭐⭐ Room with soft ambient noise (AC, fan)
- ⭐⭐⭐ Coffee shop (with a good microphone)
- ⭐⭐ Noisy office
- ⭐ Outdoors in wind or traffic
Quick fixes:
- Close windows if there is street noise
- Use headphones with a built-in microphone
- Move away from appliances (dishwasher, laundry machine)
Tip 4: Use a Good Microphone
Importance: ⭐⭐⭐⭐ Very Important
Your MacBook's built-in microphone works, but an external microphone produces noticeably better results.
| Microphone Type | Accuracy Impact | Recommendation |
|---|---|---|
| Built-in laptop mic | Good | Fine for quiet rooms |
| Earbuds/AirPods mic | Better | Good all-around choice |
| Headset mic | Best for most users | Recommended for daily use |
| USB condenser mic | Excellent | Best accuracy, especially in noisy environments |
Tip 5: Avoid Code-Switching Mid-Sentence
Importance: ⭐⭐⭐ Important
Code-switching (mixing Bengali and English in the same sentence) can confuse the romanization. The AI handles it, but accuracy drops compared to pure Bengali sentences.
| ❌ Heavy code-switching | ✅ Mostly one language |
|---|---|
| "Ami tomorrow er meeting er about bolte chacchi, basically the deadline change hoyeche" | "Ami kal er meeting er bishoy e bolte chacchi, deadline poriborton hoyeche" |
If you naturally code-switch, Banglish still works -- just expect slightly lower accuracy on the English portions. The Bengali portions will still be accurate.
Tip 6: Speak in Complete Sentences
Importance: ⭐⭐⭐ Important
The AI romanization model uses context to choose the best romanization. Single words or short fragments give it less context, which can reduce accuracy.
| ❌ Fragments | ✅ Complete sentences |
|---|---|
| "bazaar... tomorrow" | "Ami kal bazare jabo" |
| "report... pathao" | "Report ta kal pathiye diben please" |
Tip 7: Pause Between Distinct Topics
Importance: ⭐⭐ Helpful
When dictating a long message that covers multiple topics, pause briefly between topics. This helps TalkWriter identify sentence boundaries and produce cleaner romanization.
Accuracy Checklist
Use this checklist to ensure you are getting the best possible Banglish output:
- Language set manually (not Auto) -- ⭐⭐⭐⭐⭐
- Speaking clearly at natural pace -- ⭐⭐⭐⭐⭐
- Quiet environment or good microphone -- ⭐⭐⭐⭐
- External microphone if available -- ⭐⭐⭐⭐
- Minimal code-switching in sentences -- ⭐⭐⭐
- Complete sentences instead of fragments -- ⭐⭐⭐
- Pausing between topics for long dictations -- ⭐⭐
What to Do If Accuracy Is Low
If you are getting poor results despite following these tips:
- Check your language setting first -- this is the cause 80% of the time
- Test in a quiet room -- rule out background noise
- Try a shorter sentence -- isolate whether the issue is length-related
- Check Troubleshooting -- for specific error patterns and fixes
