Chunk Box User Guide: From Import to First Shadowing Session
Published on June 20, 2026
1. Import Your Audio
Start with content you actually enjoy: a podcast episode, a dialogue from a TV show, a TOEFL listening passage, or a lecture. Tap the import button and select the audio file. Chunk Box supports common formats like MP3, M4A, and WAV.
2. Let Chunk Box Split It
Chunk Box analyzes the audio and splits it into meaningful chunks at natural pauses. You can adjust the boundaries if needed. The goal is to create units that are short enough to repeat but long enough to carry meaning.
3. Listen First
Before you speak, listen to the whole clip once or twice. Get a sense of the topic, tone, and speed. Do not read the transcript yet. Let your ears do the work.
4. Shadow Each Chunk
Tap a chunk and press play. As soon as you hear it, say it out loud along with the audio. Do not wait. This immediate imitation — called shadowing — trains your brain to process sound and produce speech at the same time.
5. Record and Compare
Turn on recording and try saying the chunk on your own. Then play back the original and your recording side by side. Listen for:
- Word stress and sentence rhythm
- Linked sounds and reductions
- Intonation at the end of phrases
6. Mark What Needs Review
If a chunk is hard, bookmark it. If you find an unknown word or phrase, add a note. Chunk Box will bring these items back later using spaced repetition, so you review them at the optimal time.
7. Build a Daily Habit
Quality matters more than quantity. Even 10 minutes of focused shadowing every day will produce better results than an occasional hour-long session. Use the streak and statistics views to stay motivated.
Next Steps
Once you are comfortable with the basics, try the 100LS method: pick a one-minute clip and practice it 100 times. Or use Chunk Box to prepare for a specific test like TOEFL or IELTS by importing official listening and speaking materials.
