How the Practice Lab Works
Choose a Source Video
Paste any YouTube URL — TED Talks, news broadcasts, conference speeches, or academic lectures. The lab automatically fetches the original captions as your reference text.
Record Your Interpretation
Select your target language, press record, and interpret the speaker in real time. Your audio is captured directly in the browser — no extra software required.
Get AI Feedback
The AI transcribes your rendition, compares it against the source, and delivers detailed feedback on accuracy, fluency, phrasing, and terminology — within seconds.
What the AI Feedback Covers
InterpreT3D's AI analysis goes beyond generic correction. Each session review includes:
Accuracy & Completeness
How closely your rendition captures the meaning and key information from the source speech.
Fluency & Natural Phrasing
Whether your target-language output sounds natural to a native speaker, with idiomatic alternatives suggested where relevant.
Terminology & Register
Evaluation of specialist vocabulary use and whether the register (formal, technical, conversational) matches the source material.
Actionable Improvement Tips
Concrete suggestions and native-speaker rephrasing examples so you know exactly what to work on in your next session.

Frequently Asked Questions
Do I need any special equipment?
No. InterpreT3D works entirely in your browser. Any device with a microphone — laptop, tablet, or desktop — is sufficient.
What type of videos work best?
Any YouTube video with captions enabled works well. TED Talks and conference presentations are ideal because they feature clear speech, structured content, and reliable auto-captions.
How is the AI feedback generated?
After you stop recording, the app transcribes your audio using speech-to-text, then compares your rendition against the original video captions. An AI model analyses the comparison and produces structured feedback with strengths, areas to improve, and native-speaker phrasing suggestions.
Can I track my progress over time?
Yes. Every session is logged automatically. The Stats page shows your total practice time, daily streak, session history, and language breakdown.
