It can transcribe recordings into text in real time, with more diverse functions. In the future, with the further development of domestic artificial intelligence technology, the development of my country\'s smart recording pen market will continue to improve, and the future market development potential is huge. However, if the smart recorder wants to be sold safely in the market, it must apply for SRRC certification.
