🎗 Warm-up drills

Choose a drill, set your speed, then start

Practice speed:

🎧 Shadowing

Same language. Listen and repeat every word with a 2-3 second delay, speaking at the same time as the audio. Builds ear-voice span, fluency, and concentration under pressure.

💡 Tip: don't stop when you make a mistake - keep going and self-correct mid-stream.

💬 Paraphrasing

Same language. Press ▮▮ Pause after each sentence, restate it in your own words, then press ▶ Resume. Use the player below — spacebar also works. Builds active listening and reformulation speed.

💡 Tip: use different vocabulary and sentence structure each time to build flexibility.

🧠 Dual Tasking

Multitasking under load. Shadow a speech while performing simple physical tasks, such as writing down the numbers 1-100, writing phone numbers, or walking.

💡 Tip: have a notepad ready. Focus on capturing figures, proper nouns, and technical terms first.

Listen & record your interpretation

Play the audio — record yourself on a separate device

🎙Before pressing play, have a separate device ready to record — a phone or recorder app ready before pressing play. Record yourself interpreting as the audio plays. You will upload your recording in Step 3 to compare your interpretation to the transcript.
