Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcoming that the traditional loudspeaker can only simply amplify the sound but cannot realize the control of the PPT demonstration software, and adopts a special central processing unit with functions of speech recognition, training and speech storage, compilation and modulation The wireless transmitting module, the wireless receiving demodulation module, and the USB interface control module realize the remote voice wireless control PPT demonstration software. This invention can not only solve the single function of the traditional loudspeaker, but also facilitate the fast, accurate and intelligent use of the loudspeaker. Control PPT software presentation

Embodiment

[0013] Embodiment: A method for controlling PPT presentation software with voice input of a loudspeaker in this embodiment includes a dedicated central processing unit with voice recognition, voice training, and voice storage functions, programming and modulation wireless transmitting module, and wireless receiving Demodulation module and USB interface control module. Before using the loudspeaker, the user first needs to perform voice command training and store the specified voice command. The voice command can be "previous page", "next page", "full screen", " "Exit full screen" and so on. This system requires that the length of each voice command not exceed 1.3 seconds. When the voice command exceeds 1.3 seconds, only the first 1.3 seconds are valid. When the system starts to work for the first time, initialize the variables, input and output interfaces, RAM, call the voice playback function, and play the prompt tone for voice training. The training part includes the training o...

Abstract

The invention discloses a method for controlling PPT presentation software by voice input of a microphone. The remote voice wireless control over the PPT presentation software is achieved by a special-purpose central processing unit which has the functions of voice recognition, training and voice storage, a compilation and modulation wireless transmitting module, a wireless receiving demodulation module and a USB interface control module. First, voice control instruction training is conducted, specified voice control instructions are stored after training is over, then, voice signals input through the voice tube end of the microphone are detected and identified, after identification is successful, different control codes are sent through the compilation and modulation wireless transmitting module, then, the control codes are decoded and transmitted through the wireless receiving demodulation module and the USB interface control module, a computer is used for sending the codes to drive and control the PPT presentation software, and the microphone further achieves voice wireless control over the PPT presentation software at the same time when the microphone amplifies voices.

Description

Technical field [0001] The present invention relates to a loudspeaker, in particular to a loudspeaker that can control PPT presentation software. Background technique [0002] At present, PPT presentation software has been widely used in speech, report, publicity, teaching and other fields, but the traditional PPT operation must rely on the computer's mouse or keyboard operation when operating the page change. The National Patent Office of the People’s Republic of China published an invention patent on January 19, 2011, called the waistband type FM wireless megaphone, including FM transmitter and FM receiver. The FM transmitter includes the body and is set on the body. Inside the circuit board, a fixed installation slot is arranged on the circuit board, an antenna is arranged in the fixed installation slot, a plug-in interface is arranged on the housing, a wire is arranged in the plug-in interface, and a microphone is arranged on the wire. The frequency modulation receiving devic...
