To improve the quality of voice transmission over the network, it is essential to consider several aspects. First, you can choose to use advanced voice compression technologies, such as efficient audio codecs, which help reduce the required bandwidth and minimize quality loss during transmission. In addition, a high-speed and stable network connection must be ensured to avoid interruptions and transmission delays. It is also important to optimize the audio quality settings on the apps and devices used, making sure they are set to provide the best possible sound quality. Finally, performing periodic tests and evaluations of the quality of voice transmission, as well as collecting feedback from users, allows to identify problems and take corrective measures to continuously improve the quality of voice transmission over the network in the context of the online education.
