Using stereo-EEG in 18 epilepsy patients during naturalistic listening, we show that:
• speech → brain Granger causality peaks at theta and gamma bands.
• PAC emerges during speech (not at rest)
• theta and gamma responses come from spatially segregated sources in auditory cortex.
• speech → brain Granger causality peaks at theta and gamma bands.
• PAC emerges during speech (not at rest)
• theta and gamma responses come from spatially segregated sources in auditory cortex.

We analysed speech corpora in 17 languages and found that classic theta (~4 Hz) and gamma (~30–50 Hz) spectral signatures — and their phase–amplitude coupling (PAC) — are embedded in the speech signal itself (not just in the brain).

Are cortical rhythms entrained by speech or simply evoked?
👉 Evoked.
TL;DR:
Speech acoustics already carry the nested theta–gamma structure seen in auditory cortex.
Using advanced signal analyses, stereoEEG data, and speech corpora (17 languages).
