Provided are a detection method for a sound source and a detection device therefor, which are capable of accurately detecting the position of a sound source through use of measurement results of sound intensities. In the detection method, I_all=√(I_x²+I_y²+I_z²), which is a total value of the sound intensities I_x, I_y, and I_z in three axial directions (x-, y-, and z-axis directions) orthogonal to each other at a sound receiving point (P) in a sound field, is calculated, and then the position of the sound source is estimated after extracting the sound source by performing processing with averaged values within a predetermined peak width instead of the magnitude of a peak in a sound intensity waveform of the total value, or the position of the sound source is estimated after extracting the sound source with attention being given to a spatial travel speed of a sound intensity or a sound particle velocity of the total value.

The invention discloses an artificial intelligence speech recognition box for old people. The artificial intelligence speech recognition box comprises a box body; a signal conversion plate is fixedlyconnected to the interior of the box body; the surface of the signal conversion plate is fixedly connected with a hollow support spring; the top of the hollow supporting spring is fixedly connected with a signal receiving plate; the bottom of the signal receiving plate is fixedly connected with a vibrating rod; a metal plate is fixedly connected to the side, away from a pressure-sensitive switch,of an extrusion rod; a conductive rod is slidably connected to the side face of the metal plate; a fixing box is slidably connected to the side face of the extrusion rod; an air cylinder is fixedly connected to the side face of the hollow supporting spring, and a bearing air pipe is fixedly connected to the side face of the air cylinder. According to the artificial intelligence voice recognition box for old people, through cooperative use of the hollow supporting spring and a transmission gear, the effects that electric signals generated by sound waves are automatically improved when the speaking sound intensity is low, and the voice box can effectively receive instructions are achieved.

The invention provides a conference voice data processing method and system, and relates to the field of voice recognition. The method comprises the following steps: arranging a plurality of acquisition modules near different participants, and acquiring identity information and initial voiceprint features of the corresponding participants according to the different acquisition modules so as to acquire speech of the corresponding participants; identifying and judging whether the voice contents of the plurality of speech are the same, if so, analyzing the sound intensity of the plurality of voice contents, and selecting the voice content with the highest sound intensity; establishing a voice feature model of the plurality of participants according to the identity information and the initial voiceprint features, and inputting the selected speech into the voice feature model to obtain an identity matching result; and judging whether the identity information is matched with the identity matching result according to the acquisition modules, and if not, selecting the same voice content of the corresponding acquisition modules according to the identity matching result. The accuracy of voice acquisition of participants can be improved, and the conference recording effect is improved.
