Abstract: The present disclosure provides method and apparatus for generating a response in a human-machine conversation. A first sound input may be received in the conversation. A first audio attribute may be extracted from the first sound input, wherein the first audio attribute indicates a first condition of a user. A second sound input may be received in the conversation. A second audio attribute may be extracted from the second sound input, wherein the second audio attribute indicates a second condition of a user. A difference between the second audio attribute and the first audio attribute is determined, wherein the difference indicates a condition change of the user from the first condition to the second condition. A response to the second sound input is generated based at least on the condition change.

Abstract: Semiconductor structure and formation method are provided. A method of forming a semiconductor structure includes providing a dielectric layer on a substrate, the dielectric layer including a first region and a second region under the first region, the first region including discrete first initial nanowires, and the second region including discrete second initial nanowires; etching the dielectric layer and the first initial nanowires in the first region to form a first opening in the first region, and forming first nanowires from the first initial nanowires; etching the dielectric layer at a bottom of the first opening and the second initial nanowires to form a second opening in the second region, and forming second nanowires from the second initial nanowires; forming a second source/drain layer in the second opening; forming an isolation layer on the second source/drain layer; and forming a first source/drain layer in the first opening.
