 Hello, I'm Sarah from the ST Microwave Tronics Communications team. Hello, I am Sami from ST Microcontrollers Division. And today we're very happy to announce our new Alexa-based Voice UI reference design. And Sami here is going to tell us all about it. Sure. So we are announcing today our AVS for AWS IoT reference design. It is a Voice UI reference design based on Alexa cloud services, allowing easy and cost-effective addition of state-of-the-art voice control to embedded devices. So thanks to this reference design, it is now easy to add natural language understanding Voice UI, but also to augment the device capabilities using Alexa cloud services. Okay, cool. Right. So as everybody can see, we have our demo here. Maybe can we just quickly talk about what we're going to have in the video? Sure. So we will have today some videos showing how Alexa voice services can enhance user interfaces of smart home devices. And we will have a video showing voice quality of our voice reference design. Okay, cool. So let's jump in. Let's go. Yes, so we have two smart appliance demos, a smart hood and a smart oven. So let's start. Alexa, set hood speed to the maximum. Okay. Alexa, set oven in grill mode. Okay. Alexa, set oven temperature to 250 degrees. It's set to 250. We can also augment device capabilities asking for some advices. Alexa, how long do I need to bake a pizza? It is recommended to bake pizza for 10 minutes to 12 minutes at 450 degrees Fahrenheit. Bake until cheese is bubbling and the pizza crust is golden brown and crisp. Great. That's brilliant. So recognizing natural language and, you know, even accents. And very handy for people like me who put pizza wrappers into the recycling and don't remember how much time it takes to cook the pizza. Okay. So, I mean, why should people choose the ST solution? The solution was built with a clear focus on integration and cost effectiveness. Okay. Thanks to this reference design, you can have a support of AVS for AWS IoT standard in a single chip solution. The CM32-H743 is handling all the audio and connectivity aspects without any need for external memories, so no flash, no external run. Okay. So, unlike DSP-based solutions or Flashless-based solutions, this is the only reference design today based on single chip approach allowing cost effectiveness and simplicity. Okay. Great. So, yeah, good cost savings and efficient for designing for the customers. Yes. On top of the STM32 microcontroller, powering this reference design, also ST microphone memes and audio amplifiers are complementing the reference design in a modular approach. They are added using daughterboards and so allowing you to adapt this reference design to your own constraints. And so, for example, adjust mic spacing, adjust audio amplification to your specific end device needs. All right. Okay. So, it's really complete solution in this reference design. Absolutely. Yeah. Okay. Cool. Okay. So, before we move on to the next part of the video where we're talking about the audio performance, you know, if people want to find out more about the reference design, where should they go? What should they do? More details are available on ST.com, where you can find different information about bump cost, about schematics and more. Okay. Great. Right. So, let's talk performance. How does the reference design perform in different conditions, for example? Yes. So, the reference design passed Amazon acoustic qualifications for far field and noisy environment. It is using Amazon wake world and also using market reference audio front end with beam forming, noise reduction and echo constellation technologies. This audio front end proved great performance even with really small mic spacing for constrained environments. Okay. It sounds great. Let's see it in action. Okay. So, now let's move to our voice quality demonstration. We are in the audio lab. Our voice UI reference design is placed in front of a voice simulator that will issue the comments at a far field distance, typically three meters, and an external noise source will be played by the speakers at 65 dB. So, let's start with the test. Alexa, what time is it in Little Rock? In Little Rock, it's 7.44 a.m. Alexa, what is the capital of India? The capital of India is New Delhi. Alexa, in Rome, are we there? Thank you very much, Sammy. That was really interesting. So, as a reminder, if people want to know more, what should they do? A lot of information are already available on ST.com. And if you want to have access to this reference design, please contact your ST sales representative. Thank you. Thank you. And thank you all for watching.
