The invention relates to a metal detector, which comprises a human-machine communication system and an OSC (Open Source Commerce) reference signal generator, wherein the human-machine communication system is connected with a signal processor; the OSC reference signal generator is connected with a waveform shaping circuit, a power amplifying circuit, an emitting coil of a detecting head, a phase calibrating circuit, an orthogonal reference adjusting circuit and a synchronous demodulating circuit in order; a receiving coil of the detecting head is connected to a differential receiving circuit, the synchronous demodulating circuit, a low-pass filtering circuit, an A / D (Analog / Digital) conversion circuit and a digital signal processor in order; and the digital signal processor is also connected to the power amplifying circuit and the differential receiving circuit. Output signals of synchronous demodulating circuit after the low-pass filtering circuit are mainly envelope signals of the differential motion output signals with varied amplitude, and are sampled into the digital signal processor after A / D conversion. The digital signal processor restrains material effect signals by adding two paths of signals, collected by the A / D conversion circuit, which are respectively multiplied by a specific coefficient.

The invention belongs to the technical field of man-machine interfaces of instrument control systems and relates to a dynamic man-machine interface system based on facial features recognition and a man-machine communication method thereof. A static man-machine interface system, a camera, an alarm and a control switch are connected with an operator working state detecting module respectively; the camera is used for obtaining a real-time dynamic image in an operation area of the instrument control system and transmitting the obtained image to the operator working state detecting module; the operator working state detecting module is used for detecting and judging the image, sending a signal for reducing operator operation credibility to the static man-machine interface system and sending an alarm signal to the alarm at the same time if judging as undesirable operator working state; and the control switch is controlled by the operator and used for determining whether allowing to send a signal for reducing the operator operation credibility and the alarm signal or not. According to the dynamic man-machine interface system based on facial features recognition, a real-time working state of an operator is detected dynamically by using an image recognizing method; and the dynamic man-machine interface system has the advantages that the dynamic man-machine interface system is not easily realized by a detected individual; and the dynamic man-machine interface system is convenient to implement.

The invention discloses a deep learning-based emotional speech synthesis method and device, belonging to the field of speech synthesis. The method at least comprises the following steps: extracting text information to be processed and preceding information of the text information to be processed, the preceding information including preceding text information; The text information to be processed and the preceding information are input, and the emotional feature information is generated by the pre-built first model; the emotional feature information and the text information to be processed are used as the input, and the emotional speech is synthesized by the pre-trained second model. On the basis of only obtaining text information, based on deep learning, the synthesis of emotional speech is realized without the need to manually label each acoustic pronunciation in advance. This method can further reduce the labeling error and improve the emotional information while reducing labor costs. It can enrich the emotion of dialogue speech, improve the naturalness and fluency of synthesized speech, improve the human-computer communication experience, and has wide adaptability.
