Shared mechanisms for the processing of rhythm in music and speech

Music rhythm and speech rhythm share acoustic, temporal and syntactic similarities, and neuroscience research has shown that similar areas and networks in the brain are recruited to process both types of signals. Rhythm is a core predictive element for both music and speech, allowing for facilitated processing of upcoming, predicted elements. The combined study of music and speech rhythm processing can be particularly insightful, considering the stronger regularity and predictability of musical rhythm. Although speech rhythm is less regular, it still contains regularities, notably at syllabic and prosodic levels. In this chapter, we outline different research lines investigating connections between music and speech rhythm processing, including the recently proposed processing rhythm in speech and music framework, as well as music rhythm interventions and stimulations that aim to improve speech signal processing both in the short term and the long term. Implications for developmental language disorders and future research perspectives are outlined.
