The idea

Focus on the stressed vowel: Ofen begins with a long close o; offen has a short open o. Listen to each full example, then repeat the target word and return to the sentence. Long and short vowel categories can differ in quality as well as duration, so simply holding an otherwise identical sound longer is not a complete technique. Use the linked dictionary pronunciation guidance to interpret a model.

Avoid merging the target vowels

  • „Ofen“ und „offen“ brauchen hier keinen hörbaren Vokalunterschied. Ofen beginnt mit langem geschlossenem o; offen hat kurzes offenes o.

    The contrast carries meaning: Ofen is oven or stove; offen is open. Compare both duration and vowel quality with a dictionary model. This task does not assign an automated pronunciation score.

Watch out

Do not replace a vowel contrast with extra loudness or an invented extra syllable. Keep the surrounding consonants recognizable. Device read-aloud depends on the German voice installed in your browser and may not demonstrate every fine distinction equally clearly; it is synthetic playback, not a human recording or pronunciation assessment.
