Tone sandhi

Tone change (tone sandhi) in Taiwanese is the process of altering the tone of a syllable depending on the surrounding words and grammatical function. Most nouns in Taiwanese do not change tone. However, almost all verbs and adjectives do change tone when not at the end of a phrase.

Basic rules (Tone Circles)

Taiwanese tones in isolation, and the changes they undergo when they precede another tone.

• If the original tone number is 5 (curving-up tone), pronounce it as tone number 7 (basic).
• If the original tone number is 7 (basic tone), pronounce it as tone number 3 (low-falling).
• If the original tone number is 3 (low-falling), pronounce it as tone number 2 (shouting out).
• If the original tone number is 2 (shouting tone), pronounce it as tone number 1 (high).
• If the original tone number is 1 (high tone), pronounce it as tone number 7 (basic).

• If the original tone number is 8 (high-short), pronounce it as tone number 4 (low-short).
• If the original tone number is 4 (low-short), pronounce it as tone number 8 (high-short).
