A roundup of our Girl Geek Dinner on 24th October
We teamed up with the Bristol Girl Geek dinners network to host a Girl Geek event at XMOS HQ in Bristol. Over 45 people joined us to learn about the science of voice, see a little deeper into the magic of voice capture technology and find out how a virtual assistant can ‘hear’ your voice across a crowded room and execute your command.
It was a strong showcase of the talent in the South West, with female-identifying techies (and a few men) from across deep tech, finance, marketing, consulting and start-ups. The room was full of courage, easy camaraderie and razor-sharp minds, with representatives from the worlds of cyber-security, robotics, AI and imaging, together with others who are starting a business, freelance, starting a new life, studying or gone back to studying. With so energy and creativity across this space, it’s staggering that there’s still so little diversity.
Separating voice from noise
At the Girl Geek evening, we discussed how success of voice-enabled technology depends on its ability to identify when a human is talking and then isolate that voice signal from other noise such as room echo, other people talking, music and background or outside noise. This is achieved with a series of algorithms, housed on our silicon, which captures speech from across the room, cleans it up and sends the digital command to speech recognition service – such as Amazon Alexa.
Alex Craciun, our Algorithm Engineer, took us through the science of speech and explained that, if we know how speech is produced, we can extract features which model speech-like structures and from there create a speech detection algorithm to identify a speech source or a non-speech source accurately. Gwen Edwards, Director of Product Marketing, was then able to demonstrate the different techniques we use to extract human speech and clean up the digital signal – with the help of a talking lamp and an XMOS development kit that showed how far-field microphones and algorithms capture voice and strip out a cacophony of music to have a clear ‘Alexa ready’ voice command.
From understanding how this works, we then had a glimpse into the future at how other sensors (such as radar and imaging) will augment voice to make our interactions with technology more human. Once a voice assistant is able to sense our identity, mood, routine and personal preferences properly, it can start to evolve into something more meaningful – more like a trusted ‘digital twin’ or augmented extension of ourselves, than a tool to take orders.
Why are events such as Girl Geeks important?
Serrie-Justine Chapman, Founder of Women’s Tech Jobs says: “Bristol Girl Geek Dinners is a great network of over 850 members of brilliant, intelligent women. We welcome all women (or identifying as such) to the group whether already working in tech or simply tech-curious and wanting to see if there’s opportunity that might suit. I spent the majority of my career in that side of the industry, it’s dynamic, cutting edge and all about problem solving – great fun! I’m excited to watch the industry moves forward in such leaps and bounds and to see a Bristol based engineering company like XMOS being at the forefront of it all. Even more importantly, they’ve recognised the importance of encouraging women into the industry and are involving themselves in the change that’s needed. Our thanks to XMOS for a fabulous Girl Geek Dinner – everyone in the group is still buzzing from a great and welcoming evening!”
Here at XMOS, we look forward to holding more events like this one – and encouraging more women to come into (or back into) engineering and technology. The world’s changing and technology is moving at incredible speed – it’s time we Girl Geeks show just how much we can achieve!
XMOS is hiring!
