sip vs zip: hear and say the difference

Why this pair is hard
Spanish, Tamil and Thai have no z at all, so every plural and every 'is' ends in a hiss. Bengali, Gujarati and Korean replace z with a j sound. German and Russian devoice a final consonant, so 'rise' ends like 'rice'. Mandarin and Cantonese have no final consonants, so the ending disappears rather than changes.
