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 button adopts a split structure design, a magnet is arranged in a guide post of the lower button, and the guide post is slotted but not a through hole, but the bottom of the guide post is closed; when the button is pressed down, the bottom of the guide column is in contact with the middle contact point of the base in a plastic-to-plastic manner, so that the sound generated by collision of the guide column and the base is small, and meanwhile, the materials of the guide column and the base can be changed to adjust the key sound effect required by a user.

A speech processing system receives both text data and natural understanding data (e.g., domain, intent, and / or entity) related to a command represented in the text data. The system uses the natural understanding data to modify acoustic characteristics when determining spectrogram data corresponding to the text data based on the natural understanding data.

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.
