Richard and I began our session with a list of topics that involved /th/ words. We played a tabletop battleship game while we discussed the topic. He required minimal prompting and used /th/ in the initial position was 100% accuracy. He used medial /th/ with 75% accuracy. I introduced the "tongue tap" where /th/ is produced by quickly tapping a raised tongue behind the top teeth instead of fully protruding it out of the mouth for medial /th/. This allows Richard better control and more seamless coarticulation of sounds for medial /th/. Otherwise, his 75% accuracy of medial /th/ does not effect his intelligibility. He is doing great.
