S AND Z SOUNDS

English has both voiceless "s" and voiced "z" sounds, which may not exist in some learners' native languages. The distinction between them is important for word meaning, e.g., "sip" vs. "zip."

"S" SOUND

The "s" sound is like a soft, hissing sound.

When you say words with "s," your vocal cords don't vibrate; they stay still.

To make this sound, place your tongue close to the roof of your mouth (but don't touch it). Then, gently blow air out between your tongue and the roof of your mouth.

"S" SOUND EXAMPLES:

• snake
• sit
• sun
• see

"Z" SOUND

The "z" sound is similar to the "s" sound, but your vocal cords vibrate when you say it. It's a bit like a buzzing or humming sound.

To make this sound, do the same tongue position as "s," but let your vocal cords vibrate. It should sound like a soft "zzzz."

"Z" SOUND EXAMPLES:

• zero
• zebra
• zip
• prize

REMEMBER

The main difference is whether your vocal cords vibrate. "S" is quiet (no buzzing), and "z" is like a gentle buzz.

Listen and repeat the examples. Place your hand on your throat to feel the difference between voiceless /s/ and voiced /z/.

1. Coloca la mano en la garganta.
2. Pronuncia 'sssss' (sin vibración) y luego 'zzzzz' (con vibración).
3. Repite las listas de ejemplos.

Ejemplo 1

Diferenciar 'sip' y 'zip'.

1. Sip: /sɪp/ — sin vibración inicial.
2. Zip: /zɪp/ — con vibración inicial.
3. Toca tu garganta al pronunciar; en 'zip' sentirás vibración.

Respuesta orientativa: Porque en español estándar (excepto algunos dialectos) no existe el fonema /z/, así que tendemos a pronunciar todo como /s/.
