How do you write 智能手機 in English?

Is it: smartphone, smart-phone or smart phone?

With a hyphen, a space, or as one word?

This is an example of a technological term which has recently entered the English language. Others are:

Website, email, webpage

What often happens with technological terms is that when they first appear, they have a hyphen or space:

Web-site, e-mail, web-page

Over time, as people get used the concept and word, the hyphen tends to disappear!

But is it smart phone, smart-phone or smartphone? Listen to the programme to find out the answer.
