specific example

[0037] On-the-spot rescue and disaster relief personnel find new situations and need to communicate with the command center. First use the keypad 101 to input the other party's number, and then select the communication mode: one of boy, girl, male adult, female adult and text message. If you choose the text message mode, you can directly use the keypad to send text messages like an ordinary mobile phone; or when you choose one of the boy, girl, male adult and female adult modes according to your gender and age, you can use the special anti-interference microphone for voice recording.

[0038] When the audio analog signal enters the audio analysis and recognition engine IC (MPU) through the data line, A / D conversion is performed. The conversion is to sample and analyze the audio digital signal, extract the characteristic number to be recognized, and compare it with the stored character and word features. (The speech recognition IC used in this patent supports speech recognition ...

Abstract

The invention relates to a satellite communication system, in particular to Beidou satellite communication equipment with a voice recognition function. The Beidou satellite communication equipment is structurally characterized by comprising a voice input unit, an audio analysis and recognition unit, a satellite communication unit, an audio synthesis unit, a character storage unit and a voice output unit, wherein the voice input unit is connected with a data input interface of the satellite communication unit by the audio analysis and recognition unit, a data output interface of the satellite communication unit is connected with the voice output unit by the audio synthesis unit, and the character storage unit is respectively connected with the audio synthesis unit and the audio analysis and recognition unit. The Beidou satellite communication equipment has the advantages that the problem of communication outage when outdoor rescue and relief work is carried out far away from a base station or base stations are out of service in a large area is solved, characteristic values of audio signals of a caller are analyzed, so that the voice signals are recognized and translated into short messages to be transmitted via a Beidou satellite communication system, the short messages are converted into voices to be played after being received, and the technical effect of real-time communication of the Beidou satellite is realized.

Description

technical field [0001] The invention relates to a satellite communication system, in particular to a Beidou satellite communication device with voice recognition function. Background technique [0002] With the rapid development of China's satellite communication technology, as of now, my country has successfully launched 13 Beidou communication satellites. At the same time, the number of GPS (Global Positioning System) users in the United States is almost saturated, and the U.S. government does not promise to be responsible for civilian GPS users, and does not guarantee the accuracy and reliability of civilian GPS. In recent years, the Beidou satellite positioning and communication system has been successfully used many times in national defense military exercises. Some remote border posts in my country have been equipped with Beidou satellite communication and positioning terminals. In the past two years, the Beidou satellite positioning and communication market has been...
