A vibration exciter is disposed at a wearing position of an artificial head model where the bone conduction communication device is located. The method comprises: transmitting a test audio to first and a second digital signal processors; transmitting an audio signal processed by the first digital signal processor to the vibration exciter, and simulating vibration of a bone at a corresponding part by which human generates sound using the vibration exciter, to generate a vibration signal; transmitting an audio signal processed by the second digital signal processor to an artificial mouth and simulating human sound production to generate an acoustic signal; collecting the vibration signal and the sound signal using the bone conduction communication device, and testing the bone conduction communication device according to the collected vibration signal and sound signal.

The invention belongs to the technical field of cigarette tipping paper taste substance analysis, and particularly relates to a bionic simulation collection device and an analysis method for the dynamic migration quantity of taste substances in taste tipping paper. The bionic simulation collection device comprises a simulation lip, a simulation oral cavity, a smoke collector and a smoke suction machine which are sequentially communicated from upstream to downstream. The analysis method comprises the following steps: S1, connecting an artificial lip and a simulated oral cavity with a smoking machine, and infiltrating with artificial saliva; s2, the taste tipping paper of the cigarette is fixed to an artificial lip, the surface of the artificial lip is attached to the surface of a filter tip, and in the smoking interval process, the cigarette is inserted and pulled out; s3, after smoking is finished, the artificial lip cleaning fluid and the simulated oral cavity cleaning fluid are collected, and the migration amount of the taste substances is detected. The method is closer to the actual cigarette smoking process, and powerful technical support can be provided for cigarette product research and development, smoke physiological feeling, smoking, health and other basic research.

The application discloses a kind of intelligent cockpit voice visible can say automation test method and system, belong to automobile technical field, comprising: according to voice visible can say use scene and write test case;Test case is generated robot file and resource file by Python script, and the voice parameter required in resource file is configured in test scene;Judge whether the execution visible can say test case is dynamic name;Tactics, voice configuration parameter is input into speech synthesis model to generate wav audio file;Audio file is played by acoustic dummy-artificial mouth;Vehicle machine log and RF script assertion are grabbed by ADB command, and the vehicle machine log and RF script assertion are compared and verified;Test report is automatically generated by RF framework.The method designs test set according to visible can say use scene and process, can improve the coverage of test case, simulates intelligent cockpit user real use scene to the greatest extent.

The utility model relates to the field of floats, in particular to a fish scale float which comprises a float body, a float eye and a float foot, and fish scale blocks are arranged on the outer side of the float body in the longitudinal axis direction of the float. Extending protrusions are arranged at the two ends of the float body, and threaded grooves are formed in the ends of the extending protrusions; mounting screw rods are mounted at the positions, corresponding to the threaded grooves, of the end parts of the float mesh and the float foot, and gaskets are connected to the outer sides of the mounting screw rods in a sleeving manner. After the whole fish float enters water, the fish scale blocks on the outer side of the float body can enhance the stability of the whole fish float in the water and can filter artificial mouths of fishes, meanwhile, the extending protrusions at the two side ends of the fish float are of a conical streamline structure, and the extending protrusions are matched with the fish scale blocks on the outer side of the float body so that friction with the water can be reduced, resistance can be reduced, and stability can be improved.

The invention relates to the technical field of smart televisions, and particularly discloses a test method and a test system for voice recognition of a smart television based on real person broadcasting, which are based on the principle of voice technology, test voice recognition by using real person audio broadcasting, acquire key fields, realize automatic test and automatically generate a test report file. The test result is closer to the use scene of the user, and the test accuracy and the test efficiency are improved. The method is closer to the real human voice and can be closer to the actual use scene of the smart television, and the accuracy of the smart television voice recognition test is improved. The mode that a real person speaks an audio file and is matched with manual mouth equipment broadcasting is adopted, and compared with manual on-site broadcasting, the testing efficiency is greatly improved; by controlling a real person to speak the audio playing box to broadcast with a manual mouth, the testing process can be stable for a long time and is high in stability.
