Abstract: A data processing system implements techniques for automatically generating a presentation from a source document or a selection of a portion thereof. These techniques segment the document into a plurality of segments based on subject matter and transform those segments into textual content for slides for the presentation. The techniques also may selectively search for AI-generated and non-AI generated imagery to include in the slides for the presentation. These techniques provide safeguards for ensuring that AI-generated imagery is not utilized in instances in which such imagery would be inappropriate, misleading, or offensive. The techniques also provide means for user-specific control over when AI-generated imagery is utilized in the slides of an automatically generated presentation.

Abstract: A method includes receiving, by a second electronic device, a first working key sent by a first electronic device, and a first working key set sent by a first server to the second electronic device after the first server determines that a user of the first electronic device is a target user. In response to the second electronic device determining that the first working key set comprises the first working key, determining, by the second electronic device, that a user of the second electronic device is a suspected target user.

Abstract: A method for improving sound quality of a speaker includes: performing frequency division on an input signal of the speaker to obtain a first low-frequency input signal and a first high-frequency input signal, where the input signal is a time domain signal; performing transient detection on the first low-frequency input signal to determine whether the first low-frequency input signal is a transient signal; if the first low-frequency input signal is a transient signal, performing signal envelope modulation on the first low-frequency input signal to obtain a second low-frequency input signal; determining an output signal of the speaker based on the second low-frequency input signal and the first high-frequency input signal, where a startup voltage of the second low-frequency input signal is higher than a startup voltage of the first low-frequency input signal, and loudness of the second low-frequency input signal is greater than loudness of the first low-frequency input signal.
