The invention discloses an external voice changing method and system, and the method comprises the steps: building a mapping relation between a voice changing scene and voice changing parameters, and enabling the voice changing scene to be used for representing an external environment where a vehicle is located; in response to the user operation, determining a target voice changing scene; obtaining a target voice changing parameter corresponding to the target voice changing scene based on the mapping relationship between the voice changing scene and the voice changing parameter; and performing voice changing processing on voice played by a loudspeaker outside the vehicle by adopting the target voice changing parameter. According to the method, the voice interaction mode of the vehicle and the external environment has scene perception and self-adaptive capabilities, and the voice outside the vehicle can be matched with the specific environment and is easier to accept.

A system S according to an exemplary embodiment of the present invention acquires head-related transfer functions (HRTFs) obtained by emitting sound toward the head of an individual P from multiple sound emission directions D in an anechoic chamber, averages the plurality of HRTFs, and calculates a target response curve (TRC) for the individual P, which is referred to as TPTRC, and which clarifies information related to sound timbre. The system S generates TPTRC(W) by multiplying the TPTRC by each of different multipliers W, presents sounds conforming to the respective TPTRC(W) to individual P, to prompt individual P to select from among the sounds a preferred sound, storing the TPTRC(W) selected by individual P as TPTRCadj. The system S generates a generic TPTRCadj by averaging TPTRCadj stored for each of a plurality of different individuals P1 to Pn. A sound data processing device according to the exemplary embodiment of the present invention superimposes the generic TPTRCadj on input sound data and outputs the processed sound data to a sound-emitting device such as earphones.

The invention discloses a variable voice authentic identification and traceability method and system based on multi-task learning, and relates to the field of artificial intelligence and computer security. Obtaining an original voice sample; constructing a variable voice authentic identification and traceability model; inputting the original voice sample into a final variable voice authentic identification and traceability model to obtain a voice forgery probability and an original speaker; the variable voice authentic identification and traceability model integrates a feature extraction module, a shared encoder module, an authentic identification task branch module and a traceability task branch module; according to the invention, a joint learning framework capable of collaborative optimization and mutual promotion is constructed, multi-task learning is utilized to improve the authenticity identification accuracy and traceability of the voice-changing voice at the same time, and on the basis of high-precision discrimination of whether an original voice sample is forged or not, the original speaker voiceprint in the voice-changing voice is further reversely recovered, so that the voice-changing voice identification accuracy and traceability of the voice-changing voice are improved. And a high-performance defense technical scheme for variable voices is realized.

The utility model relates to a kind of integral switch of suspending and can change sound, including integral shell, button, suspension sleeve and return spring, recess is opened in the middle of suspension sleeve top, and suspension sleeve bottom is closed structure, magnet is embedded in recess inside bottom portion;The two opposite sides of the button are respectively provided with the guide groove passing through its top and bottom portion, and the two opposite sides of the integral shell are respectively provided with the guide rail with the corresponding side guide groove limit sliding cooperation;The other two opposite sides of the button are respectively provided with limit recess, and the other two opposite sides of the integral shell are respectively provided with the limit step with the corresponding side limit recess cooperation.The button and suspension sleeve in the utility model are split structure, when the contact point of pressing button drives suspension sleeve and integral shell bottom is contacted, both will impact to produce sound, since suspension sleeve and button are split, and there is buffering effect between both, the sound generated by button depression impact sound relative to integral handle is smaller.

A sound playback device includes: a sensor, output of which changes in accordance with a position or movement of an object including a first area and a second area; a detection part configured to detect a position of the object based on output of the sensor; a sound control part configured to control playback of sound; and a determination part configured to determine whether a first condition is satisfied based on detection results. The sound control part changes a sound playback manner when a second condition, including a position of an object detected in the first area being detected in the second area, becomes satisfied, and changes a sound playback manner based on satisfaction of a third condition including a position of an object detected in the first area becoming not detected in the detection area and the first condition being determined not to be satisfied.
