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

Provided is are a method and device for processing a voice signal and achieving multi-party conversation, and a communication terminal. The method for processing the voice signal comprises steps of receiving a voice signal of at least one transmitting terminal; performing first audio processing on a first voice signal, wherein the first audio processing comprises at least one of automatic level control processing and sampling frequency converting processing, and the first voice signal is a voice signal selected from a to-be-transmitted voice signal acquired locally and a voice signal received locally, or a signal acquired by synthesizing at least two voice signals selected from the to-be-transmitted voice signal acquired locally and the received voice signal. The method may effectively solves problems of broken voice and plosive voice in multi-party conversation, achieves multi-party conversation between different sampling rates in a broadband and a narrowband, effectively guarantees a high-quality voice conversation effect in a three-party or multi-party conversation, achieves multi-party conversation without a value-added service of a network service provider, and is more convenient for a user 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...
