How to Build a Voiceprint System? In View of Datasets

According to the “2021 China Intelligent Customer Service Market Report”, the market of China’s intelligent customer service industry will reach 3.01 billion Yuan in 2020, a year-on-year increase of 88.1%. It is expected that the intelligent customer service market may exceed 10 billion Yuan by 2025, showing a rapid growth trend.

Using NLP, ASR and other technologies, intelligent customer service can greatly improve text and language processing capabilities. It has outstanding advantages in access channels, response efficiency, data management and analysis, and improves work efficiency.

However, the problems of customers are all kinds of strange, and intelligent customer service robots are often helpless in the face of complex problems raised by customers. Both AI and ML applications are machines with their own limitations. They can only process based on the data in the system. When any query or communication exceeds their limited data, these tools can get stuck or give false and irrelevant answers. In addition, most intelligent robots on the market cannot read between the lines or fully understand the meaning of the context. There is still a long way to go for intelligent customer service to replace human customer service.

As a world’s leading AI data services provider, Nexdata has been committed to providing high-quality customer service data solutions to help empower the industry with technology and achieve the implementation of technology in more application scenarios.
