I’ve started playing with some of the machine learning APIs that AWS provides. One of these is Amazon Translate — a service that translates from English to a variety of other languages. So I thought I would make an app that uses the on-board speech recognition of an Android app, then translates it to a new language.

The requirements for this project are fairly simple. You will need an AWS account (which you can get for free), an Android phone (I had problems recording audio on the emulator so I recommend a real device), and Android Studio (which is a free download).
