多流多带方法可以在不过度增加复杂度的情况下提高语音识别系统的准确率。但不能盲目应用。在本文中，我们回顾了我们的经验，应用多流和多波段的方法对广播新闻语料库。我们发现，多流系统使用不同的声学前端提供了一个显着的改善单流系统。然而，尽管他们已经成功地在较小的任务，我们还没有能够显示使用多波段方法的任何改进。我们报告的经验，在应用这些方法在一个大词汇量的任务中获得的各种见解。
Multi-stream and multi-band methods can improve the accuracy of speech recognition systems without overly increasing the complexity. However, they cannot be applied blindly. In this paper, we review our experience applying multi-stream and multiband methods to the Broadcast News corpus. We found that multi-stream systems using different acoustic front-ends provide a significant improvement over single stream systems. However, despite the fact that they have been successful on smaller tasks, we have not yet been able to show any improvement using multiband methods. We report various insights gained from the experience in applying these methods in a large-vocabulary task.
