The utility model content
The purpose of the utility model is to solve that existing Big Dipper user terminal text input speed is slow, the literal input operation is complicated thereby in case of emergency can't edit the technical matters of distress signals, and a kind of Big Dipper user terminal with speech voice input function is provided.This Big Dipper user terminal with converting related words information to after the voice content identification, is realized the purpose of quick editing short message content then through gathering the sound that the user sends.
The utility model adopts following technical scheme to realize above-mentioned purpose: the Big Dipper user terminal of this band speech voice input function comprises Big Dipper antenna, Big Dipper signal processing module, display screen, keyboard load module, main control module, voice acquisition module and the sound identification module that is used for the user's voice information translation is become Word message; Said Big Dipper antenna, Big Dipper signal processing module are connected with main control module successively; Said voice acquisition module, sound identification module and main control module are connected successively; Said keyboard load module, display screen are connected with main control module respectively.
Said voice acquisition module is a microphone.
Said sound identification module comprises analog to digital conversion circuit, filtering circuit and the central processing unit that connects successively.
Said Big Dipper signal processing module comprises antennal interface, low noise amplifier, power amplifier, radio circuit and baseband processing circuitry; Wherein low noise amplifier, power amplifier and baseband processing circuitry are connected with radio circuit respectively; Low noise amplifier, power amplifier also are connected with said Big Dipper antenna respectively through antennal interface, and baseband processing circuitry is connected with said main control module.
Said main control module is a flush bonding processor.
The utility model has following advantage and effect with respect to prior art:
1, has the phonetic entry literal function.This function can satisfy the user on the one hand can be with convenient mode inputting word information under general case; Can guarantee that on the other hand under emergency condition and particular surroundings, still can edit short message content with the fastest speed sends; For the time has been striven in the processing and the rescue of emergency, thereby drop to loss minimum.
2, has the recognizing voice command function.Send specific instruction through voice to the terminal, like shutdown, location, transmission distress signals etc.
