    • Voice Quality Enhancement (VQE) is performed directly in a coded domain. A Coded Domain Voice Quality Enhancement (CD-VQE) system modifies at least one parameter of a first encoded signal, resulting in corresponding modified parameter(s). The CD-VQE system replaces the parameter(s) of the first encoded signal with the modified parameter(s), resulting in a second encoded signal. In a decoded state, the second encoded signal approximates a target signal that is a function of at least the first encoded signal in at least a partially decoded state. Thus, the first encoded signal does not have to go through intermediate decode/re-encode processes, which can degrade overall speech quality. The CD-VQE system may cascade functions. Computational resources required for a complete re-encoding are not needed. Overall delay of the system is minimized. The CD-VQE system can be used in networks in which signals are communicated in a coded domain, such as a Third Generation (3G) wireless network.
    • 语音质量增强(VQE)直接在编码域中执行。 编码域语音质量增强(CD-VQE)系统修改至少一个第一编码信号的参数,导致相应的修改参数。 CD-VQE系统用修改的参数替换第一编码信号的参数,从而产生第二编码信号。 在解码状态下,第二编码信号在至少部分解码状态下近似至少是第一编码信号的函数的目标信号。 因此,第一编码信号不必经历中间解码/重编码处理,这可能降低总体语音质量。 CD-VQE系统可以级联功能。 不需要完全重新编码所需的计算资源。 系统的整体延迟最小化。 CD-VQE系统可用于在诸如第三代(3G)无线网络的编码域中传送信号的网络中。
