The mobile FFMPEG library is required to convert the audio recording we will make of our speech into an MP3 format that can be consumed by the Watson speech to text service. The IBM Watson SDK will be used to interact with the Watson Speech to Text service. The first for the IBM Watson SDK and the second for the mobile FFMPEG library. In the dependencies section of the app level adle file, we will add two dependencies. Once you have created a new Android project, open the app level adle file where we make some changes. In this section of the tutorial, we will create a new Android project in Android Studio, then we will retrieve the dependencies required to use IBM’s Watson Speech to Text service in our Android app using Gradle. Once the service has been created, go into the Manage section and note the API key and the base URL of the URL shown in this screen which we will copy over to our Android app in a subsequent step.

When you are ready to create the service, select the “Create” button. We will want to use the Lite Plan for our Speech to Text service, which currently allows you to perform 500 minutes a month of speech to text for free.
