Amazon unveiled the AZ1 Neural Edge processor, a silicon module that will speed up Alexa’s ability to answer your queries and commands by hundreds of milliseconds per response. The company built this module alongside MediaTek, and it will allow for on-device neural speech recognition for new products.

It’s built into the new Echo smart speaker, Echo Dot and Echo Dot with clock, Echo Dot Kids Edition, and Echo Show 10 smart display it announced today — though only the Echo and Echo Show 10 have the on-device memory needed to support Amazon’s new all-neural speech models, the company tells us. The AZ1 will also be built into more products in the Echo lineup going forward.

Amazon’s preexisting products without the AZ1 send both the audio and its corresponding interaction to the cloud to be processed and back. The Echo and Echo Show 10 can handle the audio on-device, thus limiting the amount of time it takes to give users a response. And despite how these devices process your voice, how you view your voice history and utterances in the Alexa app isn’t changing.

Amazon says these latency benefits will be available first for English in the US, but it plans to expand to more languages “in time.”

This partnership between Amazon and MediaTek is reminiscent of Microsoft’s partnership with Qualcomm on the SQ1 processor made for the Surface Pro X, at least in terms of big companies co-engineering silicon with chipmakers. In practice, the AZ1 seems more similar to Google’s Neural Core that’s implemented in the Pixel 4. In addition to helping to improve photography, that dedicated chip enables the device to understand spoken English, to the point where it can transcribe recordings in real time without being connected to the internet.

Amazon hasn’t made the claim that these Echo devices can be used offline, but by handling more on-device than in the cloud, it should make for a slightly better user experience. We’ll be testing it out soon in the Echo Show 10.

Updated 3:00PM ET: Added more devices that will feature the AZ1, including the Echo Dot, Echo Dot with clock and Echo Dot Kids Edition.

Update, 8:10PM ET: Clarified that only the Echo and Echo Show 10 will have the faster locally generated results.
