在这里，我们提出了一种稳健的语音识别算法，用于辅助设备的语音激活控制。我们实现了一种基于Mel倒谱系数互相关的有效方法。该方法在低噪声环境下具有较高的精度。因为我们的实现是基于每个命令的一组训练样本，所以它可以很容易地适应任何用户。一旦加载了训练集，就将每个命令与训练集中所有样本的MFCC进行比较。然后，我们使用“赢家通吃”的方法来决定该命令属于哪个组。
We present here the implementation of a robust voice recognition algorithm for voice activated control of assistive devices. We implemented an effective method based on cross correlation of Mel Frequency Cepstral Coefficients (MFCC). The developed method yields high accuracy in low noise environment. Because our implementation is based on a set of training samples for each command, it can be easily adapted for any user. Once the training set is loaded, every command is compared to the MFCCs of all samples in the training set. We then use a "winner-takes-all" method to decide which group the command belongs to.
