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.

Keep the tongue high and forward; round the lips only for the second word.

What you are learning
After most initials, pinyin i is a clear high front vowel. On its own it is written yi. After z, c, s, zh, ch, sh and r the same letter means something different.
What your mouth is doing
The front of the tongue rises close to the hard palate, the jaw is nearly closed and the lips are spread.
Compared with English
English ee in see is close, though many English speakers glide into it. Hold Mandarin i steady from start to finish. The short i in English sit is a different vowel and should not be used.
Build the sound, step by step
- Smile slightly and raise the front of your tongue.
- Hold yī steadily with no glide.
- Say bǐ, dì and qī, with the same tense vowel.
What to watch for
- Using the vowel of sit makes bǐ sound lax. Tense the tongue.
- Reading shī or sī with this vowel: those use the empty i.
