AB - Neural activity tracks the envelope of a speech signalat latencies from 50 ms to 300 ms. Modulating this neural trackingthrough transcranial alternating current stimulation influencesspeech comprehension. Two important variables that can affectthis modulation are the latency and the phase of the stimulationwith respect to the sound. While previous studies have found aninfluence of both variables on speech comprehension, theinteraction between both has not yet been measured. We presented17 subjects with speech in noise coupled with simultaneoustranscranial alternating current stimulation. The currents werebased on the envelope of the target speech but shifted by differentphases, as well as by two temporal delays of 100 ms and 250 ms.We also employed various control stimulations, and assessed thesignal-to-noise ratio at which the subject understood half of thespeech. We found that, at both latencies, speech comprehension ismodulated by the phase of the current stimulation. However, theform of the modulation differed between the two latencies. Phaseand latency of neurostimulation have accordingly distinctinfluences on speech comprehension. The different effects at thelatencies of 100 ms and 250 ms hint at distinct neural processes forspeech processing.
