Talkers adjust their speech to resemble that of their interlocutors—a phenomenon known as speech convergence. Broadly defined, convergence describes automatic synchronization to some external source, and this effect has been recognized in various linguistic domains (e.g., syntactic structuring, morphological choices, and vowel production). Using a speech-in-noise reading-task, this paper explores whether or not speech production also converges with non-linguistic signals: Specifically, might a speaker’s rhythm, pitch or intensity be influenced by fluctuations in background music? Participants read passages aloud while music was presented at ~45 dB(A) via headphones. Music was composed with relatively flat envelopes in the domains of interest, and in test-conditions only Pitch, Tempo, or Intensity was altered. Manipulation was gradual (linear function) and would similarly return to the point of origin after reaching a target (Pitch = -200 cents; Amp = + 6dB; Tempo = -20 beats per minute).
