Intelligibility enhancement describes intervention to improve the clarity of speech in multilingual speakers. Intelligible speech, as part of spoken language proficiency, is essential for successful verbal communication. Intelligibility is important for all people, ranging from typical speakers to children with speech sound disorders and people with dysarthria, dyspraxia, and dysphonia. Intelligibility is also necessary for effective communication in multilingual speakers when they are speaking a language other than their home language (e.g., Vietnamese speakers using English). Some multilingual speakers find that listeners have difficulty understanding them in their second (or third, fourth, or fifth) language because the sound system of their home language interferes with or transfers to their pronunciation in their other language. Most people learn new languages by focusing on vocabulary and grammar with minimal focus on learning the sounds (consonants, vowels, tones, prosody) of the new language, how they are made, and the difference between these sounds and those of the speaker’s home language.
