You're about to listen to a BBC podcast and maybe it's when I had a hand in.

I'm Tammy Walker and I produce podcasts for the BBC.

My role is to give new and diverse creators a voice with the opportunity to build a career.

That's the thing I love about podcasts.

You start with just a good idea, but then you have the space to see where it goes.

And doing that at the BBC means we can really run with the best stories

while developing the most unique audio talent.

So if you like what you hear, why not check out the huge range of podcast we've got on BBC Sounds?

Hello and thanks for downloading this podcast. I'm Marnie Chesterton, fallible human and presenter of crowd science from the BBC World Service.

And I should probably introduce the thing that's going to take my job.

Alexa, introduce yourself.

Hello, Marnie.

I am a voice-activated smart speaker from Amazon you might recognize.

Other brands are available.

I can answer questions, play music, podcasts and

radio stations and access various data from the internet, but today I shall

mainly be helping you present your program.

Alexa, can you tell me what the remit of crowd science is?

Crowd science, as everybody should know, is the BBC program that takes answers from you

the listener and scours the world in search of an answer.

Mm, whatever. I still reckon my job is safe for at least another six months.

Alexa, why are you here?
