 Hello, my name is Maria Luisa Sacchi and I'm business development manager at BD Sound. BD Sound is a company based in Milan and we are ST's official partners. We are leading provider in the audio and speech processing fields and today at SensorExpo 2018 we are presenting our voice recognition and audio quality enhancer with the dual microphone interface. I will let Aldo, my colleague, to show you our demo. Hi, I'm Aldo Ricci, design engineer for BD Sound and today we are showing you our PCB prototype based on two MEMS microphones by ST and Cortex-M7 STM32F7 as a core processor for our AESR enhancer algorithms. So what we have here is something that interacts with a vocal assistant and I will try to show you a few use cases that we cover. Alexa, sing a song. Alexa, stop. So I was able to interrupt it very quickly, very respondingly so my colleague now will try to replicate some audio interferers coming from one side of our device which is placed in between us and I will try to interact with that even though we have this kind of interference. So Maria, you will start. Alexa, what's the capital city of Brazil? Brazil's capital city is Brasilia. Alright so you could see that even though we have like a very high interference coming from the other side the vocal assistant was able to understand what I was saying at the same distance with pretty much the same voice level. Thank you.
