Vocal folds: vibrating

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

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

Compare steady a with the same start plus a glide.

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 a is the most open vowel in the system and an easy place to practice tones, because the mouth has plenty of room.

What your mouth is doing

The jaw opens and the tongue lies low and roughly central. The lips are neutral. Its exact quality moves forward before n and back before ng.

Compared with English

The a in English father is close, although it is often further back in English. Do not use the a of English cat, and do not add an r colour as many English accents do in car.

Build the sound, step by step

  1. Drop your jaw and say a long, relaxed a.
  2. Hold it steady, with no glide at the end.
  3. Say mā, má, mǎ and mà, keeping the same vowel on each tone.

What to watch for

  • Reading a as the vowel in cat makes bā sound wrong. Open further.
  • Letting a glide to ow or eye changes the final to ao or ai.
