Australians hoping to get their hands on one of the most sought-after features in Google Pixel 3’s latest smartphone – the ability to stop telemarketers in their tracks – will miss out.

Call Screen, the telemarketer-detecting software on the new phone, will be released only in the US, a Google Australia spokeswoman told The New Daily.

Nor was there any date for its likely release here.

Call Screen uses Google’s Duplex technology to answer calls and instantly transcribe them.

The phone’s owner can then choose if they want to take the call. Calls from telemarketers can be instantly marked as spam.

Two versions of the new smartphone – the Pixel 3 and Pixel 3 XL – Google’s Home Hub and a Pixel Slate (tablet) were unveiled in New York on Tuesday (local time). 

The Pixel 3 will rival the best phones on the market, with Google’s greatest weapon: artificial intelligence (AI).

Google’s senior vice-president of hardware, Rick Osterloh, started the launch by showing off the tech giant’s slew of new products and highlighting the AI features. 

“This approach is what makes Google’s hardware experience so unique and it unlocks all kinds of helpful benefits,” Mr Osterloh said.

Earlier leaks of many of the phones’ hardware specs were on the money, including the 5.5-inch and 6.3-inch displays on the Pixel 3 and Pixel 3 XL.

The phones are available in 64GB and 128GB storage options.

A feature called Top Shot uses AI to help capture the perfect photo.

For example, when taking a motion photo, it captures alternate shots in HDR+, then recommends the best photo – choosing one where everyone is smiling and facing the camera.

Another highlight is the rear-facing 12.2-megapixel camera and two front-facing 8MP cameras.

Other features include Night Sight, used in low-light settings without a flash, and Super Res Zoom, which improves zooming without losing image quality.

The phones come in three colours, with somewhat quirky names: Just Black, Clearly White and Not Pink.

They have glass backs with matte and glossy textures in two tones.

Pre-orders for the Google Pixel and Google Pixel XL can be made at the Google Store, with the phones launching on November 1. There are no plans to sell the Pixel Slate in Australia.

Pricing for Australian customers start at $1199 for the Pixel 3 and $1349 for the Pixel 3 XL.

The Google Home Hub has a 7-inch display screen with an internet-connected speaker.

It is similar Amazon’s Echo Show and Facebook’s new Portal. However, unlike its rivals, Google has opted not to include a camera, saying it wants to ensure users feel comfortable using the device in private spaces.

The Home Hub supports YouTube – complete with Google Assistant voice controls such as (“Play my favourite song”) – as well as music services such as YouTube Music, Spotify and Pandora. 

The Home Hub will be released in Australian stores on October 23. It will retail for $219.
