Google Duo upgrade will ready the worst thing about video calls

Poor internet connections can ruin a video call, turning a group chat into an irritating mess of glitches, hanging and dropouts. But Google Duo aims to tackle that with the power of artificial intelligence.

Announced via a Google AI Web log post, a new voice communication codec called Lyra is gear up to better vox advice by compressing the user's speech into a lower bitrate "even on the slowest networks." That basically means there'll exist a reduced chance of glitches, dropouts and freezing, and thus less disruption in video calls.

Aimed at reducing data usage and minimizing latency when compressing and transmitting voice signals, Lyra is surprisingly non that complex in the mode it works.

Every 40 milliseconds, the codec extracts any noticeable features or "distinctive oral communication attributes" from the user, which are and then "compressed for manual." The encoded features are then used to recreate the speech indicate using Lyra's generative model at the receiving end; basically what a person on the other end of a Duo call will hear.

According to Google, "since the inception of Lyra, our mission has been to provide the all-time quality sound using a fraction of the bitrate information of alternatives."

For reference, Opus, 1 of the most popular audio codecs, is designed to obtain transparent speech quality at 32kbps (kilobits per second), though this can go down to 6kbps with noticeably worse quality if needed. In comparison, Lyra operates at just 3kbps, significantly reducing overall information usage.

Google's listening tests also claim that "Lyra outperforms whatever other codec at that bitrate and is compared favorably to Opus at 8kbps, thus achieving more than a threescore% reduction in bandwidth."

In several sound examples included in the blog post, we can clearly hear a drastic improvement in quality when using Lyra at 3kbps as opposed to Opus at 6kbps.

This ultimately means that users suffering from inconsistent internet speeds will soon be able to see an improvement in call quality when using Google Duo on either Android or iOS devices. However, it's unclear as to when exactly Lyra volition become widely available.

To ensure amend functioning, Lyra is constantly being trained through machine learning using countless hours of speech audio data. The sound comes from speakers fluent in over 70 languages to enable wider international usage.

Google's blog also mentioned that in addition to constantly improving Lyra, the squad is exploring ways as to how information technology can use the aforementioned technology to meliorate other codecs in the future.
