| /s/ | The tongue is behind the teeth. | | | The teeth remain clenched. | The air flows through the tip of the tongue towards the edge of the teeth. | The vocal cords do not vibrate. |
| /p/ | Place the tip of your tongue behind your upper front teeth, or slightly below them, so that the air is completely blocked in the oral cavity. | Round your lips tightly, creating a seal to prevent any air from escaping through your mouth. | Keep your jaw relatively tense and stable, without any movement. | The teeth should not be involved in the production of this sound. | Build up air pressure behind the blockage created by your tongue and lips, and then release the air suddenly by popping open the lips, causing a burst of air to be expelled. | Do not use your vocal cords to produce this sound, as it is an unvoiced sound. |
| /i/ | The tongue is tense and rises high. Then it moves to the front of the mouth. The tip of the tongue is low and behind the bottom front teeth. | The lips are tense and wide. | The jaw drops, opening the mouth a little. | | | The vocal cords vibrate. |
| /ʧ/ | Raise the front part of your tongue toward the hard palate, the bony roof of your mouth just behind your upper teeth. The sides of your tongue should touch your upper molars. The tip of your tongue should be behind your upper front teeth. | Keep your lips slightly apart and relaxed. | Keep your jaw slightly open and relaxed. | Touch your upper and lower teeth lightly together. | Push air out of your lungs, through your mouth and over your tongue. | Keep your vocal cords apart, so that the sound is voiceless. |
