Vocal folds: vibrating

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

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.

What your mouth is doing

The jaw opens for an open central or front starting point. The tongue then rises toward /ɪ/, and the jaw closes within one syllable. Vowel length changes before the next consonant: ride is longer than write.

Comparing with Mandarin and Spanish

Written i can be /aɪ/ in time or /ɪ/ in tin, and final e often signals the first. Many words use igh or y, such as light and my. Exceptions like island and buy need to be learned as words.

Mandarin ai and Spanish ai, as in baile, are close starting points, without Mandarin tone. Spanish readers should remember that letter i is often /aɪ/ in English.

Build the sound, step by step

  1. Open your jaw for a wide start, as in the beginning of my.
  2. Raise the tongue smoothly toward /ɪ/, closing the jaw as you go.
  3. Say time, light and high, then compare ride and write.

What to watch for

  • Reading the letter i as in Spanish or pinyin gives tim for time. Check the silent final e.
  • Pronouncing gh or s in light and island follows the letters. Both are silent in these words.

Hear the difference in your own voice

Compare time and Tim, then light and lit. Glide in the first word of each pair, and use the short steady /ɪ/ in the second. Then try ride and write to hear the length change.
