Hello, I'm Manuela Saragossa. Welcome to Business Daily from the BBC. Coming up, there's a global

shortage of native English language teachers. There's 55,000 language schools in China, implying 400,000

teachers. The demand is... The amount hugely outstrips the supply. Yes, it's not feasible to do it, yes.

But then, with modern technology, will we even need language teachers in future?

I speak to you in Spanish.

We'd send that speech signal to the cloud.

Within maybe 1.5 seconds, you'll hear the translation directly in the earphone.

Wow, that is really fast. That's all here in Business Daily from the BBC.

By next year, two billion people will be speaking or learning English around the world.

So says the British Council, the UK's international organisation for cultural relations and

educational opportunities. The problem is there just aren't enough English language teachers to meet

the demand. It means new ways of teaching are opening up. More on that in just a moment. But first,

imagine a world where language is no barrier.

Yes, these days, there really is a tech solution to everything.

This one comes not from Silicon Valley, but from New York City, home to 8 million people speaking pretty much every single language under the sun.

It's where the BBC's Kizzy Cox went to meet the team at Waverly Labs,

a tech startup creating a very special set of earphones.

Hi.

Kizzy.

Yes, yes.

Nice to meet you, Andrew.

Nice to meet you.
