SOUND CONTRAST

s · sh · x: three fricatives

Separate s, sh and x using the same three tongue positions. Practice sān, shān and xiān until each sounds distinct.

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 airflow steady 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 fricatives share the three tongue positions of the affricate sets. Because they can be held, this is the best set for feeling the positions.

What your mouth is doing

For s, the tip is forward. For sh, the tip is raised and drawn back, without touching. For x, the tip is down and the blade high, with spread lips. The hiss gets darker as the tongue moves back.

Compared with English

English s is close to Mandarin s. English sh falls between sh and x and usually rounds the lips, so it does not match either exactly. Hold each sound for two seconds and slide between them.

Build the sound, step by step

  1. Hold s, then slide your tip back to sh.
  2. Hold sh, then drop your tip and raise the blade for x.
  3. Say sān, shān and xiān.

What to watch for

  • Using English sh for both sh and x merges two sounds.
  • Rounding the lips for x is a common English habit. Spread them unless ü follows.
