中文摘要 | 近年来,语音交互技术迎来了新的发展高潮。语音交互技术的性能得到了极大提升,语音交互技术的产品层出不穷。语音识别是语音交互系统中的前端处理模块,其性能对语音交互系统的性能非常重要。但是,传统的语音识别在交互方面仍然存在一定的不足,不能适应新产品的需要。比如,其交互的内容仅是转写文本,存在信息缺失的问题;其输入方式是按压或点击,存在操作不方便不自然、并且易受空间距离、环境光线影响的问题;其输出方式是在整句语音被完全输入并完全识别后才输出转写文本,存在响应不够快速的问题。其较少的交互内容和不自然的交互方式不利于用户的体验。 因此,本文以提高语音交互的友好性为目的,主要围绕语音识别中更丰富的交互内容,和语音识别中更方便自然的交互方式这两个方面进行了研究和探讨。下面是本论文的主要创新点和贡献。

英文摘要 | In the past few years, speech interaction technology has experienced a new wave of development. The performance of speech interaction technology has been greatly improved. And a lot of products of speech interaction technology have been developed. Speech recognition is the front-end processing module in the speech interaction system. Its performance is very important to the performance of the speech interaction system. However, there are still some deficiencies in the traditional speech recognition, which can not meet the needs of new products. For example, its interactive content is transcript; there is a problem that some information is lost. Its input method is to press or click; there is a problem that the operation is inconvenient and not natural. And its output method is that the transcript is outputted after the whole speech was completely inputed and fully recognized; there is a problem that the response is not fast enough. The less interactive content and the unnature interaction methods are not good to the user experience. Therefore, this paper aims to improve the friendliness of speech interaction. It focuses on the two aspects, which are the enrichment of the interactive content of speech recognition, and the more convenient and natural way of interaction. The main work and contributions are as follows.
