This is a whispy and unvocalized scratch sound that is done by controlling the airflow between your teeth and your lips.
{ wsh }
How it's done
- The simplest way to describe this is to say chowi, fwish, or fwewa
- Control the outward airflow by wrapping and moving your lower lip over your bottom teeth
- To make it more scratch-like fade in the ch part so it sounds more like schowi or tschowi.
- The more advanced version will be a triplet saying tschowichi tscho - wi - chi.
