z: unaspirated dental affricate

Pinyin z sounds like the ds in English kids, with no voice and no puff. Learn zǐ, zài and how they differ from zh and j.

Vocal folds: vibrating

TongueTeethUvula

Simplified human pronunciation. The small uvula hangs from the palate; it is not the vocal folds. The wave indicates voicing.

Sound to demonstrate
Tone

High and level, around 55 on the five-level pitch scale.

Voice settings

The mouth starts slightly open. Movement is slowed for observation; the synthetic sound plays once at its original speed. Pause holds the current mouth shape; reset returns to the relaxed position. The panda is a symbolic teaching aid for human pronunciation, not animal anatomy. A simplified teaching model, not a measured or anatomically validated simulation. It shows the soft palate lowering for nasal sounds, but not airflow. Single syllables use eSpeak NG, a synthetic voice on your device. Its pitch range is narrower than natural speech, so use the tone diagrams and word buttons as well. Words and sentences use a voice from your browser or device when one is available. No native recordings are bundled.

Listen and compare

Same mouth position; add a puff on the second word.

Pinyin here shows dictionary tones. Spoken tones change in some contexts, such as nǐ hǎo; see the lessons on tone changes.

What you are learning

Pinyin z is not the buzz of English zoo. It starts with a closure, and it is not voiced in the English sense.

What your mouth is doing

The tip touches just behind the upper teeth, stopping the air, and then releases into a narrow s-like hiss with little breath.

Compared with English

The end of English kids or cats is the nearest cue: a stop followed by a hiss. English puts that sound at the ends of words, so beginners need practice starting a syllable with it.

Build the sound, step by step

  1. Say cats and hold the ending.
  2. Move that ending to the start of a syllable: z-ài.
  3. Say zài, zǎo and zì with no puff and no buzz.

What to watch for

  • An English z buzz in zài replaces the closure. Start with the stop.
  • Adding air changes zì to cì.
