Soon Google Duo voice calls are also coming. Google Duo is the latest sensation from Google to make one-to-one video calls. The main attracting point of the app is, unlike Skype, Duo purely depends on our mobile number.
Whatsapp users have been waiting for Whatsapp video calling for a long time. Google Duo may become an attractive alternative for those we are expecting video calling from Whatsapp. You no need to create a separate account to use Duo. Similar to Whatsapp your mobile number is your identity, and you can make calls to those who are already there in your contacts.
Video calling is ok, but what about audio calls? Most of the times people prefer voice calls instead of video. In this context, in the upcoming versions, Google Duo is going to introduce voice calls support also.
Voice calls will be available in two modes. One is direct voice calls by selecting the voice call button. The second one is while talking in video calls if your net connection became unstable the video call automatically transforms into voice calls.
Google Duo already offers scaling of video quality depending on the bandwidth available on your phone. If you are using the slow net connection, the video automatically streams in low bitrate with poor quality. If there is no proper connection there, Google Duo automatically switches the call to audio mode instead of disconnecting the call.
