S is a thin, high hiss. SH is deeper and wider.

This can be trained

Hearing S and SH apart is a skill, not a talent. Little training research has looked at S and SH on their own, but the method behind TellApart, high variability phonetic training (HVPT), is well tested. Ron Thomson's 2018 review of 32 HVPT studies found strong evidence that it works and that the gains last.

How to hear the difference between S and SH

Listen to the pitch of the hiss. S is a thin, high, sharp hiss. SH is lower and wider, more a hush than a hiss. The skill is catching that difference in every voice, above all before ee and i, where Japanese blurs the two.

How S and SH are made

For S, the front of the tongue comes close to the ridge just behind the upper teeth, and air rushes through a narrow groove against the teeth. The result is a high, sharp hiss, like air escaping a tire.

For SH, the tongue pulls a little further back and the lips push forward into a slight round. The channel is wider and the space in front of it longer, so the hiss drops in pitch and spreads out: the "shh" you use to ask for quiet.

Why do S and SH sound the same to Japanese speakers?

Japanese has no "si". The syllable し (shi) uses a sound between English S and SH, made with the tongue raised toward the roof of the mouth. So see tends to come out as シー (shii), much like she.

Katakana shows it: sea and she are both シー (shii), seat and sheet are both シート (shiito), sip and ship are both シップ (shippu), and seen and sheen are both シーン (shiin). Before other vowels, katakana does keep them apart: sell is セル (seru) and shell is シェル (sheru), sign is サイン (sain) and shine is シャイン (shain).

So the hard part is before ee and i. Japanese し sits between the two English sounds, so English S and SH can both seem close to it. In a study by Lambacher and colleagues (2001), 104 Japanese students of English picked out S and SH almost every time before the e of bet (94% and 95%), but before the ee of see, S fell to 72% and SH to 41%.

What to listen for

Listen to the pitch. S is high and thin, SH lower and fuller. Held on their own, sss and shh are easy to tell apart. The skill is hearing the same difference inside a quick word.

Before ee and i, as in seat and sheet or sip and ship, listen hardest: this is where Japanese し would stand in for both. A sharp, narrow hiss is S.

At the end of a word, as in mass and mash or class and clash, the hiss comes last with nothing after it. Listen to that last sound on its own.

When it matters: meaning

Mix them up and you get a different word. A seat is a chair, a sheet covers a bed or is a page of paper. To sip is to drink a little, a ship sails. To save is to keep or rescue, to shave is to cut hair close to the skin. Same means identical, shame is the feeling after something embarrassing. A sign is a notice, to shine is to give off light. A class is a lesson, a clash is a fight.

Many everyday words start with S before ee or i: see, sit, sick, single, city. Said with SH, some become other words, and a few become rude ones, so this pair matters for speaking as much as for listening.

How to practice hearing S and SH

Use many voices. A higher or lower voice moves both hisses up or down, so many voices teach you the difference between the two sounds, not one speaker's pitch.

Check every answer right away, keep sessions short, and go in order: S and SH before other vowels first, like sell and shell or same and shame, then before ee and i, like seat and sheet or sip and ship, then at the end of a word, like mass and mash.

S is also the sound Japanese learners put in place of the TH in think. TellApart has TH · S as a collection too.

How quickly you improve differs from person to person, so aim for short, regular sessions.
