Retora Mic Check · Free tool
Drill your articulation, right in the browser.
Read 30 tiered Indonesian tongue twisters. The bot listens, scores your clarity word by word, and plays back how it should sound. A 5 minute warmup before an event. The sentences are in Indonesian, so this drills Indonesian articulation.
Hit Record, read the sentence, read the score.
Five steps, no setup, no account.
Everything runs in your browser. Audio goes straight to the transcription service and is never stored.

Hear the example
The bot reads the correct intonation pattern using the id-ID voice in your browser.

Click Record, speak clearly, and the bot listens until you finish.
04
Check the score per word
Green is on target, amber is close, red missed. Work on the red words first.
05
Go again
Repeat until it lands, or move to a new sentence. Progress saves automatically.
What people ask before they start.
Is my voice stored anywhere?
No. The Web Speech API sends audio straight to the browser vendor to transcribe, Chrome to Google and Safari to Apple, then returns text. Retora never receives or keeps the audio, and your progress stays in this browser.
Why Chrome or Safari on mobile?
Speech-to-text in the Web Speech API is not supported by Firefox or Safari on desktop. Chrome, Edge, and Safari on mobile work. The page checks first and tells you up front, so nothing fails silently.
Why is my score low when I sound clear?
Indonesian recognition in the Web Speech API lands around 70 to 85 percent on average. If one word keeps missing, that word is worth drilling. If everything misses, check your mic and the room noise first.
How do I move on to coaching?
Look at the Retora curriculum and programme pricing for tiered speaker growth with experienced trainers. This drill covers articulation only, which is one slice of delivery.
Honest note and next step
Chat on WhatsApp→The bot checks articulation. A trainer works on the whole delivery.
The bot measures how clearly you pronounce the target text. For feedback on intonation, gesture, storytelling, and MC flow, you need an experienced trainer reviewing you directly. A free initial consultation with the Retora team recommends a track and starting level for your target.
