Recently, "audio libraries" with flexibility, diversity and full scene advantages are "emerging" in local public libraries, urban study, communities, parks and subways. Although the "audio library" covers a small area, it has rich resource reserves. People can easily enjoy rich listening services by scanning QR codes on their mobile phones. "The bird wants to fly high, first flutter its wings, and the man wants to make progress, first read." With the development of mobile Internet, the information that can be read every day is dizzying. Although reading forms are more diverse and convenient, it is still a luxury for many people to sit down and concentrate on reading. For this reason, more and more people like "listening to books" from listening to information and novels on the way to and from work, closing their eyes to listen to online courses in their spare time, and then joining the "audio library". According to the survey, in 2020, more than 30% of China's adult citizens have the habit of listening to books, and the scale of audio reading continues to expand. From "reading" to "listening", from "silent" to "sound", sound reading makes the fragrance of books more refreshing. "Reading" with ears has become a new "posture" of reading. To some extent, audio reading not only liberates both hands, but also eyes. High quality voice and frustrated emotion also help to improve users' cognition of content and make reading "pleasant to read". At the same time, everyone's reading needs are different. Traditional paper books are difficult to meet the diversified and personalized reading needs of a large number of readers, and audio reading makes up for this shortcoming to some extent. On the one hand, today's audio reading content is very rich. It is not limited to traditional broadcast audio novels and book reviews, but also includes more detailed products such as party history learning, management and humanities, children's education and so on. On the other hand, audio reading makes it more convenient to acquire knowledge. People of different ages, different knowledge levels and different industry characteristics can find products that meet their own needs and enhance their sense of cultural acquisition. More importantly, when the pace of life is getting faster and faster, many people can't help feeling "where has time gone". The time to calm down and concentrate on reading and patiently chew knowledge is quite limited; Because of its convenience, audio reading adapts to the general trend of the popularity of personal mobile communication tools. In addition, it has convenient storage and large capacity, which can meet people's needs of real-time reading. You don't have to hold books all the time and find time to read. Just make flexible use of fragmented time such as eating, commuting and outdoor entertainment, you can open the reading mode anytime and anywhere, feel the highlights in the book with your ears and experience the pleasure of reading. What needs to be faced up to is that although audio reading has become an important way to obtain knowledge and information, with the rapid development of the industry, there are problems such as scattered upstream resources and uneven content quality in the audio reading market. In addition, the goal of barrier free use of audio resources for special groups has not been well achieved. Only by standardizing development, establishing and improving rules and standards, can the audio reading industry have a better future. For personal reading, we also need to constantly expand the boundary of reading. From the reading experience, audio reading is more suitable for easy to understand books, such as novels, biographies, historical popular science, etc. If people are eager to think deeply and read academic works or professional books, they may also need to return to the traditional way of text reading. Whether reading or listening to books, in the final analysis, it is to keep people alive and inspired by wisdom. The development of science and technology can change the way of reading, but it can not change the law of knowledge accumulation and learning. "There is a road to the mountain of books, diligence is the path, learning is boundless, and hard work is the boat". The key words of reading have always been perseverance. The law of "no small step, no even thousands of miles; no small stream, no river and sea" will not change. In this sense, audio works help people take the first step of "listening because of sound", but "thinking because of listening" and "understanding because of listening" still depend on the readers themselves.
