Design a Minimal Pair Drill for a Tricky Sound Contrast

Two sounds blur together in your target language and you keep saying the wrong one. This builds a practice session around that contrast: why it trips up speakers of your language, twelve minimal pairs, and a drill order. For self-studying learners working on a specific pair their ear and mouth keep merging.

I am preparing self-study pronunciation exercises for {LEARNER_NATIVE_LANGUAGE} speakers learning {TARGET_LANGUAGE}. The sound contrast I want to target is {SOUND_CONTRAST} (e.g. /æ/ vs /ɛ/).

Please design a complete minimal pair practice session:

1. Explain why this contrast is difficult for speakers of {LEARNER_NATIVE_LANGUAGE}.
2. Generate 12 minimal pairs that isolate the contrast. Include word-initial, medial, and final positions where possible.
3. Write three short listening discrimination sentences where the meaning changes depending on which sound is used.
4. Suggest a 10-minute daily drill routine using these pairs.
5. Describe what the learner should listen and feel for when self-monitoring.

Format each section clearly with headers.
