Google Duo Adds Audio Calling to Its Video Chat App

Google Duo is a video chat application compatible with both Android devices and smart displays powered by the Google Assistant, that will merge later this year into Google Meet, adding features like virtual backgrounds.

No registration or account are needed – simply a phone number will do. This service can only reach people on your contacts list, and cannot access any private data on your device.

Video Calling

Duo is an easy and fun video calling app designed to connect with those with the app installed or in your contact list. The interface is user-friendly and features such as seeing who is calling before answering can serve as a deterrent against unwanted calls. Best of all, Duo is completely free download without needing an associated Google account for use!

Duo automatically searches for people or groups you want to call when you open the app, displaying results for you to select and begin calling them. While on call, both parties involved can see your live image while switching between front and rear cameras or muzzling yourself as needed is also supported. In addition, Duo offers low-light features which reduce lighting during video calls so that you can look your best during conversations.

Duo stands out as an essential feature by being capable of working over low bandwidth connections, using a video codec which reduces data requirements to create full-quality video calls – making it particularly beneficial for those with limited data plans or poor mobile networks.

Google announced this week it is adding several new features to Duo this week, including photo mode that enables side-by-side photos during video calls and group call functionality that enables up to 12 people at the same time to join.

Duo offers both video and audio calls. In addition, users can make audio-only calls and record messages and send them directly to any number. All calls and messages are end-to-end encrypted. Furthermore, Duo supports augmented reality effects during video chats so you can add filters or effects such as 3D overlays that move with you as you move your head during conversations. Furthermore, Family mode makes Duo easier for children to use it.

The app also comes equipped with several settings, such as the option to disable Knock Knock and enable Low-light mode, setting vibrate while ringing or restrict mobile data usage – even unregistering your number from within the app if no longer desired!

Voice Calling

Google Duo was introduced last year as an emerging market-friendly alternative to Apple FaceTime and WhatsApp, and is now providing audio calls as part of its service. The feature can easily be enabled within the app itself.

Duo is a simple video chat app for Android, iOS, tablets and web browsers; as well as smart speakers like the Nest Hub Max. It’s free of charge with end-to-end encryption capabilities and packs surprisingly powerful functionality into its straightforward appearance.

After installing Google Duo, users will need to link a cellular phone number and verify their identity through a verification code sent via text message. After doing this, they can connect with friends also using Duo or directly dial numbers directly using Duo’s dialer feature. Furthermore, they can choose whether Duo can access contacts, receive push notifications, and turn on Knock Knock for real-time preview of callers before answering.

The user interface is user-friendly and straightforward, featuring icons to start calls or end them, along with options to mute audio or switch cameras as well as easily locate a mute button. There are also settings available to block numbers, limit mobile data usage and unregister phone numbers so as to prevent others from signing up with the service using those same numbers.

One-to-one call features are great, but group video calls, which already exist on other apps, could bring even more people onto Duo and increase its adoption rate, particularly in regions experiencing social distancing. Furthermore, it would be nice if there were an option to save voice and video messages instead of having them expire after 24 hours; Google reportedly is working on such a feature; however it may be delayed until an upcoming update or simply discontinued altogether.


Google Duo video calling app will soon offer a feature similar to Instagram or Facebook Stories: you can now post messages that include text or doodles for 24 hours after no one can call back. This update is rolling out today on both Android and iOS devices.

Duo’s new Messages feature is part of its ongoing effort to offer a comprehensive messaging experience. While not offering as many features as dedicated apps like Allo or Hangouts, such as sharing photos between Duo users or sending personalized notes via the app – it provides some alternatives. Duo offers photo sharing functionality between users while providing personalized messaging capabilities within an already impressive video calling app.

To send a message, tap on the Messages icon at the bottom of your Duo screen. Select who you wish to address it too; up to 32 people can be added for one message. When ready, press record on your Duo camera. Finally, personalize it further with filters and effects as you record your video message; choose from eight background colors and six different font styles when recording a video message!

Duo messages automatically delete after one day, though you have the option of saving them to your phone locally. In addition, messages and calls sent via Duo can be replied back using a button at the top of your screen; Duo also offers Family Mode that enables parents to monitor children’s usage of Duo as well as prevent sharing inappropriate material.

Duo’s creators have been adding new features to Duo over the last several weeks. Duo even made Digital Trends’ list of best video chat apps for mobile phones! Additionally, Knock Knock allows you to preview a video call before answering. This can be especially helpful for users who wish to maintain privacy; however, Duo may find difficulty competing against messaging services like WhatsApp which have gained in popularity over time.


Google Duo is a video call app with many privacy-focused features, such as end-to-end encryption. This ensures that only you and the person you are calling can read your messages; this prevents telecom providers, internet service providers and government agencies from listening in on conversations – making this technology far superior than Skype or Facebook Messenger which do not use such technology.

Google Duo app is easy to set up on both Android and iOS devices, using your phone number as identity verification to keep conversations secure from outside interference. Plus, with its Knock Knock feature that lets you see who is calling before answering their calls – an extra layer of protection against spam calls or scams!

Blocking specific numbers is another privacy feature available on iOS that will protect you from unwanted calls and allow you to focus on what matters. From the menu bar, simply choose from a list of numbers you would like blocked – saving yourself from unwanted interruptions while helping you focus on what matters. Plus, customize notifications only when calls come from specific contacts!

Google is well known for protecting their users’ privacy. Over time, the company has made significant strides in improving its privacy tools and products to meet users’ demands for security. Google Duo stands out as an attractive messaging and video call app because it does not require creating an account with them; however, your call history will still synchronize across devices where Duo is installed.

Duo also allows users to delete call history on an individual contact basis and seamlessly switch between Wi-Fi and cellular data without dropping calls, as well as detect when connection quality drops, automatically lowering resolution resolution if necessary. It supports group video calls of up to 12 people across mobile devices or PCs running Chrome browser.

Google Duo is a quality, secure video chat application, ideal for keeping in touch with friends and family without fear of their privacy being breached. Unfortunately, however, this service doesn’t provide instant messaging features similar to popular services like WhatsApp, Viber or Skype.
