Telegram has announced the rollout of voice calls to its platform. This comes months after the company asked users in a survey about what kind of features its users would want implemented in the app.
According to the blog post, the new update will rollout to Western Europe in the first stage with gradual rollout to countries across the world. The company assures that the call quality will be clear and fast in addition to the security standard - end to end encryption - that one has come to expect from Telegram.
The voice calling interface is normal like any other calling app, with no overhauls to the experience on the surface. The company has extended its end-to-end encryption technology used in Secret Chats to audio calling. However, the company has made the encryption process easier by improving the key exchange mechanism. Using this you no longer need to verify a long cryptic key code to ensure that the call is secure. Instead, the screen shows four emoji signs which you can cross-check to confirm security and privacy.
The company has used state-of-the-art audio codecs to reduce the data used while providing crystal-clear voice quality. The app uses peer-to-peer connection but if that can't be established then it uses the closest server to the location to connect the user to the audio call in the shortest amount of time.
The distributed infrastructure model of Telegram helps it achieve speed in calling and all other operations in comparison to other messaging apps. Telegram detailed that it will expand its content delivery network around the world in coming months to improve the connection speeds even in remote areas.
The most interesting thing for this update is the use of Artificial Intelligence, a neural network to be precise to improve the voice calling on the app. A neural network learns about the technical details like network speed, ping times, packet loss percentage every time one would make a call, helping it to optimise the parameters based on this input to improve the quality of future calls in those conditions.
The parameters can be adjusted in the same call if the system shifts from cellular data to stable Wi-Fi connection. The company has promised that it does not collect any other information for the AI to function ensuring privacy during audio calls.
The addition of this new feature also comes with full privacy settings for calls where the users can block certain contacts to turn the voice calling feature off entirely. Telegram has also added a 'Use Less Data' if the users want to reduce the consumption even lesser than what is is right now. As soon as the update rolls out for everyone, users will see a calling button in the profile section.
Last but not the least, Telegram has added controls for users to select the degree of compression of videos before the users share these videos with their friends and family. According to the company the app will remember the compression the user selected and then proceed to send the video in that quality. Once selected, the app will use the same quality for all the videos that you send.
