摘要： Disclosed are a target speaker separation system, an electronic device and a storage medium. The system includes: first, performing, jointly unified modeling on a plurality of cues based a masked pre-training strategy, to boost the inference capability of a model for missing cues and enhance the representation accuracy of disturbed cues; and second, constructing a hierarchical cue modulation module. A spatial cue is introduced into a primary cue modulation module for directional enhancement of a speech of a speaker; in an intermediate cue modulation module, the speech of the speaker is enhanced on the basis of temporal coherence of a dynamic cue and an auditory signal component; a steady-state cue is introduced into an advanced cue modulation module for selective filtering; and finally, the supervised learning capability of simulation data and the unsupervised learning effect of real mixed data are sufficiently utilized.

摘要： An atomic force microscope has dual probes composed of a hinge structure, two cantilever beams and needle tips arranged on free ends of the cantilever beams. The hinge structure is a U-shaped body having two ends respectively extended with a first cantilever beam and a second cantilever beam. The free end of the first cantilever beam and the free end of the second cantilever beam are respectively provided with a first needle tip and a second needle tip. The integrated dual probes is operated by the driving function of the probe clamp. Therefore, only a set of motion control and measurement system of the atomic force microscope is required to realize the rapid in-situ switching function of the dual probes.
