- [Instructor] In this and the next several videos,
we're going to present a case study
for our traveler's companion translation app.
So, suppose you're a traveler and you speak English
and you're traveling to a Spanish-speaking country.
Let's assume you don't speak Spanish
and that you need to communicate with somebody
who doesn't speak English.
So of course there's tons of different apps out there
nowadays that you can carry around on your cellphone
that will help you with just that scenario.
And what we wanted to do here was just use this scenario
as a way to introduce working with various web services
provided by IBM Watson
and also to show you how easy it can be
to implement an app using these powerful web services.
So we're actually going to work with three Watson services
as part of implementing this app
and basically what the app will do is enable two people
who speak English and Spanish respectively
to communicate with each other in near real time,
just some delays over the network
as the English spoken language
is taken from spoken language to text.
Then from English text to Spanish text.
Then from Spanish text into Spanish audio.
And the audio gets played back.
And then in reverse,
we'll do the same thing to enable the Spanish speaker
to respond perhaps to a question
that you might be asking them
like where is the nearest bathroom.
So we're going to be combining those services together
into what is commonly referred to as a mashup
which is simply taking multiple web services
and combining them to perform some greater task.
