语言视角
在母语中
Lexical tone is critical in Mandarin; pitch contour distinguishes word meanings, and tone sandhi and neutral tone affect real pronunciation.
妈、麻、马、骂。
mā, má, mǎ, mà = different tones, different words
在目标语言中
Punjabi has lexical tone; some Gurmukhi letters and word positions signal tonal contrasts rather than simple aspiration.
ਘੋੜਾ ਦੌੜਦਾ ਹੈ।
The horse runs.
Learners may pronounce written voiced aspirate letters as plain consonants and miss the tone contrast.
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
