An aspiration contrast without changing the word target

A learner studies 包 bāo and 抛 pāo using written Pinyin. Both examples share the written final ao and the first-tone category, while the initial contrast concerns aspiration. The learner can select the right option but then produces both words with the same consonant release. A teacher asks for a focused comparison using a reliable recording and a short meaningful phrase. No actual recording is embedded in this exercise, so the written answer cannot establish that the production improved. The purpose is to identify what to compare and how to avoid confusing aspiration with loudness or an English voicing distinction. This is language learning, not medical diagnosis of a speech condition or a certified PSC score. The learner’s home-language sound system should be discussed respectfully while practicing the specified target.
