Embodiment 1

[0053] refer to figure 1, the embodiment of the present invention provides a voice communication method, the method is applied to a voice communication device, the voice communication device includes a sending end and a receiving end, the sending end and the receiving end are connected through a communication network, and the sending end pre-stores the first key, the method includes the following steps:

[0054] Step S101: the sending end converts the pre-acquired first analog voice signal into a first digital voice signal.

[0055] The sending end is connected with an audio device. During voice communication, the external audio device sends the first analog voice signal to the sending end. After receiving the first analog voice signal, the sending end converts the first analog voice signal into a A digital voice signal.

[0056] Step S102: The sending end encrypts the first digital voice signal to obtain a second digital voice signal.

[0057] The sending end pre-stores th...

Embodiment 2

[0062] refer to figure 2 The embodiment of the present invention provides another voice communication method, the method is applied to a voice communication device, the voice communication device includes a sending end and a receiving end, the sending end and the receiving end are connected through a communication network, and the sending end includes a first serial number The decoder and the first processor, the receiving end includes a second codec and the second processor, the first processor and the first codec are connected in communication, and the second codec is connected in communication with the second processor, the method Include the following steps:

[0063] Step S201: The sending end randomly generates a first serial number, and sends the first serial number to the receiving end.

[0064] The sending end includes a first codec and a first processor, and the receiving end includes a second codec and a second processor. Before voice communication, the sending end...

Embodiment 3

[0119] refer to image 3 , The embodiment of the present invention also provides a voice communication device. The voice communication device includes a sending end and a receiving end, and the sending end and the receiving end are connected through a communication network.

[0120] Specifically, the sending end includes a first codec 302 and a first processor 301, the receiving end includes a second codec 303 and a second processor 304, and the first processor 301 and the first codec 302 are connected in communication, The second codec 303 is communicatively connected to the second processor 304 .

[0121] The first codec 302 is configured to convert the pre-obtained first analog voice signal into a first digital voice signal, and send the first digital voice signal to the first processor.

[0122] The first processor 301 is used to randomly generate the first serial number, and send the first serial number to the second processor 304, and calculate the first serial number a...

Abstract

The embodiment of the invention provides a voice communication method and device and belongs to the communication technical field. The voice communication method is applied to the voice communication device. The voice communication device includes a transmitting end and a receiving end; the transmitting end and the receiving end are connected with each other through a communication network; and the transmitting end and the receiving end pre-store first keys. The method includes following steps that: the transmitting end converts first analog voice signals into first digital voice signals and performs encryption processing on the first digital voice signals so as to obtain second digital voice signals; the transmitting end transmits the second digital voice signals to the receiving end; the receiving end performs decryption processing on the second digital voice signals according to the first keys so as to obtain third digital voice signals; and the receiving end converts the third digital voice signals into second analog voice signals. With the voice communication method provided by the invention adopted, the security of voice communication can be effectively ensured, and the data and privacies of users will not leak assuredly.
