摘要： Provided are an automatic speech translation system and a method for obtaining accurate translation performance with a simple structure. Because input and output sentences are written in different languages, automatic speech translation requires techniques for processing different languages. Repetition of text processing like morpheme analysis or sentence parsing in conventional automatic speech translation can complicate the overall translation process. Meanwhile, although input and output sentences are written in different languages, they have to have the same meaning and a corresponding sentence form and words. Accordingly, the corresponding words and sentence forms of the two languages can be expressed with a simple structure and utilized in the automatic speech translation process, thereby maintaining consistency during the process and avoiding unnecessary process repetition, which reduces errors and improves performance.
摘要翻译：提供了一种自动语音翻译系统和一种以简单的结构获得准确的翻译性能的方法。由于输入和输出句子是用不同的语言编写的，所以自动语音翻译需要处理不同语言的技术。在常规自动语音翻译中重复文本处理，如语素分析或句法解析可能会使整个翻译过程复杂化。同时，虽然输入和输出句子是用不同的语言编写的，但它们必须具有相同的含义和相应的句子形式和单词。因此，两种语言的对应单词和句子形式可以用简单的结构表示，并在自动语音翻译过程中使用，从而保持过程中的一致性，避免不必要的过程重复，从而减少错误并提高性能。
