Advancements in communication technologies have broadened the scope for audio transmission and application. For instance, continuous improvements in network bandwidth have enabled high-definition audio calls and high-quality audio streaming services. Meanwhile, audio technologies are increasingly integrated into communication devices and systems. Typical examples include intelligent voice assistants deployed on mobile phones and in-vehicle communication systems, which greatly enhance the convenience and intelligence of communications. In the future, the communication and audio industries will continue to achieve in-depth integration, constantly innovating application scenarios and service modes to bring greater convenience and richer experiences to people’s daily lives and work.
