To do this, you will want to change the class declaration in your MainActivity.java to: This class will enable use to to use Google’s voice to text engine and add our own custom actions at different points in the voice recognition life cycle. To get our speech recognizer to work, we’ll need to implement RecognizerListener. Now that you have a UI with a TextView and Button, it’s time to get into the meat of the code. Implement RecognizerListener in our Main Activity
In this example I’ve also wrapped the TextView in a ScrollView, just in case there is enough text to fill the page! The interface looks pretty simple, but will do just fine for what we need.Ĭurrently, my activity_main.xml file looks like this: Īndroid:layout_width='match_parent'Īndroid:layout_height='match_parent'Īndroid:orientation='vertical' />We’ll use the button to turn on/off listening for speech, while the TextView will be used to place our converted speech text on the screen.
I’ll also choose to create an empty activity for this example.įor the purpose of this simple speech to text tool, let’s create a new Activity with only two elements on the page: a TextView and a Button or ImageButton. I’ll name my project “Speech Recognizer”, but you can name it whatever you like. Go ahead and create a new project using the “Create New Project” wizard in Android Studio. To get started, let’s first create a new project in Android Studio. Basic Android knowledge like how to create a layout and run a program.An Android Smartphone or Tablet (Unfortunately, Voice Recognition does not work on an emulator).Android Studio IDE downloaded and configured on your PC or Mac.By the end of this short tutorial, you’ll have a working version of a voice to text dictation app! Prerequisites In this article, we’ll learn how to build a simple speech to text app on Android using the speech recognizer library provided by Google. Many apps out there utilize the speech recognition feature, such as Google Keep. However, using Googles Speech to Text API, its actually quite simple.
If you’ve ever wanted to integrate speech to text into your applications, you might have though that it would be difficult or complicated. These systems wouldn’t be possible without some kind of underlying technology that is able to convert our spoken audio into discernible text. Industry leaders like Google, Amazon, Apple, and Microsoft are all betting on voice assistants by creating interfaces like Google Assistant, Siri, Alexa, OneNote dictation and Cortana. Just look at the VUI (Voice User Interface) systems many of us have in our homes like Google Home and Alexa. Voice To Text services are all the rage these days.
