Embodiment 1

[0082] In this embodiment, the process of using the present invention to implement a three-party call is described in detail, and the three parties include a local terminal and two other terminals. The local terminal is a dual-mode, dual-standby communication terminal.

[0083] Figure 4 It is a schematic diagram of a dual-card dual-standby communication terminal provided in Embodiment 1 of the present invention to realize a three-party call, as shown in Figure 4 As shown, the terminals for the three-party call include local terminal C1, terminal A and terminal B, wherein, local terminal C1 has built-in subscriber identification cards SIM3 and SIM4, terminal A has built-in subscriber identity card SIM1, terminal B has built-in subscriber identity card SIM2, and terminal A A communication connection is established with the local terminal C1 through the GSM network, which is a narrowband voice call, and a communication connection between the terminal B and the local terminal C...

Abstract

A voice signal processing, a method and device for realizing a multi-party call, and a communication terminal. The voice signal processing method includes: receiving a voice signal from at least one sending terminal; performing first audio processing on a first voice signal, and the second The audio processing includes at least one of automatic level control processing and sampling frequency conversion processing, and the first voice signal is a voice signal selected from locally collected voice signals to be transmitted and locally received voice signals or A signal obtained by synthesizing at least two voice signals selected from locally collected voice signals to be sent and received voice signals. It can effectively solve the problems of popping and breaking sounds during multi-party calls, realize multi-party calls between broadband and narrowband voices with different sampling rates, effectively ensure high-quality voice calls in three-party or multi-party calls, and do not need to pass through the network operator's Value-added services can realize multi-party calls, which is more convenient for users to use.

Description

technical field [0001] The invention relates to the field of voice signal processing, in particular to a method and device for processing voice signals in a multi-party call, a method and device for realizing a multi-party call, and a communication terminal. Background technique [0002] With the widespread use of mobile devices, the demand for multi-mode, multi-card and multi-communication communication terminals is increasing. In the process of people using the communication terminal for voice call service, the basic voice service involves two callers, that is, the two callers can hear each other's voice. In addition to the above-mentioned one-to-one call, a three-way call can also be realized , The three-party call can provide the convenience of three customers talking at the same time, that is, dial a third party without interrupting the call with the other party, and realize the three-party call together. During a three-party conversation, the voice signal of any party...
