This document presents the International Phonetic Alphabet (IPA) symbols for disordered speech. It includes symbols for consonants organized by place and manner of articulation. Diacritics are provided to denote features like voicing, nasality, and strength of articulation. Symbols are also given for connected speech phenomena like voicing assimilation and speech rate. The document aims to comprehensively cover symbols for transcribing disordered or atypical speech sounds.
