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

Keep the air small and only move your tongue.

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

These three sounds are different places for the same kind of stop-plus-friction, with no puff. English j covers part of the same space, so they are easily merged.

What your mouth is doing

For j, the tip is down and the blade high. For zh, the tip is raised and drawn back. For z, the tip is forward behind the upper teeth. Note that the vowel differs too: ji has a true i, while zhi and zi have the empty i.

Compared with English

English has only one similar sound in judge. Think of three separate tongue positions, not three variations on English j. Regional speakers may merge zh and z, which is a legitimate accent feature, but learners should keep them distinct at first.

Build the sound, step by step

Say jī, feeling your tip behind the lower teeth.
Say zhī, with your tip raised and back.
Say zī, with your tip forward. Go back and forth slowly.

What to watch for

Using an English j for all three loses all the contrasts.
Adding a puff turns these into q, ch and c.
