For example, the current document information is divided into 4 paragraphs, and the 3 content tags obtained by speech recognition include: product name, promotional planning and dissemination topics. After the content tag is obtained, marking the content participating in the content tag extraction in the document information, for example, if the content tag of "product name" is obtained based on the first segment, marking the first segment as a first text area; and marking the second paragraph and the third paragraph as a second character area if the content label of the 'propaganda plan' is obtained based on the second paragraph and the third paragraph, marking the fourth paragraph as a third character area if the content label of the 'propagation subject' is obtained based on the fourth paragraph, and directly obtaining the character area corresponding to the manuscript information corresponding to each content label in the optimal presentation manuscript template, and filling to construct and obtain the corresponding delay manuscript.
