However, there are several synonyms that describe people who perform similar roles. Linguists study language and how it works, including phonology. Speech pathologists work with individuals who have difficulties with speech and language, including sound production. Phonemicists focus on the analysis of speech sounds and their functions in a specific language. Phoneticians specialize in the acoustic and articulatory properties of speech sounds.
