| /ʃ/ | The tongue raises a bit in the middle. It does not touch the roof of the mouth. It presses against the inside corner of the top teeth. The front part of the tongue comes down not touching anything in the mouth. | The corners of the lips are in. The rest of the lips flare. | | The teeth are together. | Air passes through the mouth. | 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. |
