Embodiment Construction

[0019] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] refer to figure 1 As shown, it is a hardware configuration diagram of the voice transmission device 100 in an embodiment. The voice transmission device 100 is mainly used in some electronic devices that can realize two-party or multi-party voice communication, such as mobile phones, landline phones, and computers. Received sounds other than the user's voice (hereinafter referred to as "environmental noise") are suppressed. In this embodiment, the voice transmission device 100 is composed of the following parts: an input unit 110 , an analog / digital conversion unit 120 , a sound analysis unit 130 , an encoding / decoding unit 140 , a transceiver unit 150 and a storage unit 160 . In this embodiment, the input unit 110 is a microphone.

[0021] The storage unit 160 stores voice data of a specific user. The voice data...

Abstract

The invention discloses a voice transmission device which is used in electronic equipment capable of realizing two-party or multi-party voice communication. The voice transmission device comprises a storage unit in which a voice material indicating voice characteristics of users is stored, an input unit, an analogue / digital conversion unit, a voice analysis unit, a coding / decoding unit and a transmitting unit. The invention further provides a voice transmission method comprising the following steps of: inputting voice; converting the voice into digital signals; analyzing which digital signals are the user voice digital signals, and which digital signals are the environment noise or others voice digital signals; shielding the digital signals of the environment noise or others voice; and coding and transmitting the digital signal of the user voice to the opposite side of call. By utilizing the voice transmission method and the voice transmission method, the environment noise or others voice can be shielded, and the purposes of improving the call quality and protecting the privacy of own call environment are realized.

Description

technical field [0001] The invention relates to a voice transmission device and a voice transmission method thereof. Background technique [0002] In modern life, when using mobile phones, landline phones, computers and other electronic devices that can realize voice communication between the two parties, sometimes because the user is in a noisy environment, in order to allow the other party to hear clearly, it is often necessary to raise the voice. , or half-cover the microphone with your hand. For another example, when the user does not want the other party to hear the surrounding sounds in some special environments, and it is inconvenient to leave the environment, a voice transmission device that can shield the ambient noise is needed. Contents of the invention [0003] In view of this, the present invention provides a voice transmission device to solve the problem in the prior art that environmental noise cannot be shielded. [0004] A voice transmission device is us...
