ABSTRACT Robust speech interaction in complex acoustic environments represents a critical challenge in human‐computer interaction. Conventional air‐conduction microphones are susceptible to environmental noise, limiting their application in noisy scenarios. To address this, we present an anti‐interference skin‐compatible voice patch (AISC‐VP). The device operates by adhering to the neck and capturing surface micro‐vibrations, thus physically bypassing ambient noise interference. Constructed from a polyurethane‐enhanced silk fibroin film (P‐SF) and a fluorinated ethylene propylene (FEP) woven layer, the sensor demonstrates exceptional mechanical properties, moisture permeability, and optical transparency. It exhibits a frequency response across a broad 20–10 000 Hz range, achieving a signal‐to‐noise ratio of 63.5 dB with a full width at half maximum below 0.3 Hz. For noise‐robust recognition, the AISC‐VP demonstrates only a 0.74% increase in character error rate when transcribing audio from an 85 dB high‐noise environment compared to direct recognition of original audio, while significantly outperforming microphones. By taking advantage of the natural orthogonal characteristics of the voice and touch spectra, zero crosstalk voice‐touch dual‐mode operation is reliably achieved without misjudgment in a high‐noise scene. This work provides a high‐performance hardware solution for speech capture in noisy environments, demonstrating AISC‐VP's potential for intelligent communication, health monitoring, and human‐computer interaction.
