A computationally efficient speech enhancement pipeline in noisy environments based on a single-processor implementation is developed for utilization in bilateral cochlear implant systems. A two-channel joint objective function is defined and a closed form solution is obtained based on the weighted-Euclidean distortion measure. The computational efficiency and no need for synchronization aspects of this pipeline make it a suitable solution for real-time deployment. A speech quality measure is used to show its effectiveness in six different noisy environments as compared to a similar one-channel enhancement pipeline when using two separate processors or when using independent sequential processing.
基于单处理器实现，开发了一种在噪声环境中计算效率高的语音增强流程，用于双侧人工耳蜗系统。定义了一个双通道联合目标函数，并基于加权欧几里得失真度量获得了闭式解。该流程的计算效率以及无需同步的特性使其成为实时部署的合适解决方案。使用一种语音质量度量来表明，与使用两个单独处理器或独立顺序处理时的类似单通道增强流程相比，它在六种不同噪声环境中的有效性。
