In one possible embodiment, as shown in fig. 3, the system further comprises a monitoring device 14 for monitoring the target area; the monitoring device 14 is configured to send the acquired monitoring data of the target area to the information processing device 11; the monitoring device 14 includes, but is not limited to, a smoke detector, a pressure sensor, a gas detector, a water immersion sensor, an infrared sensor, and a subway/bus operation monitoring device, and in the scenes of fire protection, natural disaster early warning, and the like, the monitoring data may be at least one of numerous environmental data such as temperature, humidity, smoke concentration, rainfall intensity, dust concentration, soil humidity, and the like, and in the broadcast scenes such as airports, stations, and the like, the monitoring data may be the data such as the takeoff/departure time, the landing/arrival time, and the like of the airplane/vehicle; the information processing device 11 is further configured to receive the monitoring data, analyze the monitoring data, and determine that an event to be notified exists in the target area according to the monitoring data, and after receiving the monitoring data sent by the monitoring device 14, the information processing device 11 analyzes the monitoring data by using a big data analysis or model prediction, so as to determine that an event to be notified exists in the target area, for example: the rainfall intensity and the soil humidity of a certain area are analyzed, and whether landslide and debris flow waiting notification events exist in the area or not can be predicted. For example: and when the smoke concentration of a certain area reaches a preset value, determining that a fire disaster and explosion waiting notification event exists, and generating the information to be transmitted or receiving the information to be transmitted input by a user under the condition that the event to be notified exists in the target area. The information processing apparatus 11 is further configured to send, to the information sending apparatus 12, identification information of the target information receiving apparatus 1301 arranged in the target area. The monitoring device 14 has a one-to-one correspondence with the target area, for example: the target area can be a certain floor or a certain household of a certain residential building, or can also be a certain factory building of a certain industrial park, or a certain landslide monitoring area, the smoke detector A1 is distributed and controlled in a northwest corridor of a certain residential building 8, and then the identification information of the target receiving equipment corresponding to the northwest corridor of the building 8 is 8NW, and the like. When the monitoring device 14 sends monitoring data, the information processing device 11 records a target area monitored by the monitoring device 14, and queries the relevant record table according to the target area, thereby obtaining identification information of a target receiving device corresponding to the target area where an event to be notified exists, the information processing device 11 can send the identification information of the target information receiving device 1301 corresponding to the target area to the information sending device 12, and the information sending device 12 can directly send encoded information to be transmitted to the target information receiving device 1301 according to the identification information, so as to implement unicast and broadcast for the target area.

converting the second feature sequence into a second audio signal to be processed, and identifying the keyword from the second audio signal to be processed;
and correcting the current tone of the keyword by adopting a preset coefficient to obtain the second audio information.
Specifically, the information processing apparatus 11, in dividing the text information into M text segments, is configured to: detecting punctuation marks in the text information by using a regular expression, performing word segmentation processing on the text information to detect out words such as "over", "or" yes "and the like from the text information, and segmenting the text information by using the punctuation marks and the words as segmentation points to obtain M text segments to be processed, for example: "Please note that gas leakage occurs in a certain area, please catch up with the evacuation bar! "please note" is divided into two text segments "please note" and "please note" to be processed, a gas leakage occurs in a certain area, the symbol of the end of the text segment is used as a division point to become a single text segment to be processed, and "please catch up with the evacuation bar! "due to the Bar" and punctuation "! "continuous, and thus serves as a segmentation point. And filling the tail of each text segment to be processed with the phoneme of the last word of each text segment to be processed in the M text segments to be processed to obtain M text segments, so as to solve the problem of audio discontinuity caused by directly converting the M text segments to be processed into audio segments and splicing. The keywords in the text information can be matched through a keyword template, and can also be determined by a TextRank algorithm. The preset coefficient is used to correct the current tone of the keyword mainly for enhancing the tone of the keyword, such as "fire", "landslide", "fast run", and other keywords, and therefore, the preset coefficient is usually a positive number greater than 1.
In addition, if M is 3, (y1, y2 … y12) is a feature subsequence corresponding to the first audio segment, (y13, y14 … y20) is a feature subsequence corresponding to the second audio segment, and (y21, y22 … y30) is a feature subsequence corresponding to the third audio segment, then the first feature sequence is (y1, y2, y3 … y30), when a feature subsequence segments are selected, two adjacent feature subsequence segments may bring in the same feature, and the number of the same feature may be customized, for example, 2, that is, the first feature subsequence segment (y 30, y30 y30, y30) in the a feature subsequence segments may be selected, the second feature subsequence segment (y 30, y30 y30, y30), the third feature subsequence segment (y 30, y30, y30 y30, y30) in the B target features, that is the same feature subsequence segment (y 30, y30, y 30).
Further, in terms of updating the first feature sequence based on the a feature subsequence segments and the B target features to obtain a second feature sequence, the information processing device 11 is specifically configured to:
