A sound ________ is the insertion of a sound or sounds that are not part of the word itself, such as 'animamal' for 'animal'.

A sound addition refers to the inclusion of extra sounds that do not belong to the standard pronunciation of a word, such as saying 'animamal' instead of 'animal.' This phenomenon is often seen in children's speech as they develop their language skills, where they may add syllables or sounds in their attempts to pronounce words more effectively. This is particularly common in early language learners, reflecting their ongoing efforts to master the complexities of phonetics and phonology.

In contrast to other types of errors, such as substitution, omission, and distortion, which involve changing, leaving out, or misarticulating sounds, addition specifically highlights the introduction of sounds that distort the intended word but do not align with its standard form. This helps to characterize specific speech patterns and provides valuable insights into children's developing language abilities.
