Installation

Using npm:

npm install --save react-native-speech

or using yarn:

yarn add react-native-speech

Linking

Automatic

react-native link react-native-speech

For iOS users using Pods: You need to run pod install after running the above link command inside your ios folder.

Manual

Add the following line to your build targets in your Podfile

pod 'RNSpeech', :path => '../node_modules/react-native-speech'

Then run pod install

In XCode, in the project navigator:

• Right click Libraries
• Add Files to [your project's name]
• Go to node_modules/react-native-speech
• Add the .xcodeproj file

In XCode, in the project navigator, select your project.

• Add the libRNSpeech.a from the RNSpeech project to your project's Build Phases ➜ Link Binary With Libraries
• Click .xcodeproj file you added before in the project navigator and go the Build Settings tab. Make sure All is toggled on (instead of Basic).
• Look for Header Search Paths and make sure it contains both $(SRCROOT)/../react-native/React and $(SRCROOT)/../../React
• Mark both as recursive (should be OK by default).

Run your project (Cmd+R)

• optional in android/build.gradle:

...
  ext {
    // dependency versions
    googlePlayServicesVersion = "<Your play services version>" // default: "+"
    compileSdkVersion = "<Your compile SDK version>" // default: 23
    buildToolsVersion = "<Your build tools version>" // default: "25.0.2"
    targetSdkVersion = "<Your target SDK version>" // default: 22
  }
...

• in android/app/build.gradle:

dependencies {
    ...
    implementation "com.facebook.react:react-native:+"  // From node_modules
+   implementation project(':react-native-speech')
}

• in android/settings.gradle:

...
include ':app'
+ include ':react-native-speech'
+ project(':react-native-speech').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-speech/android')

• in MainApplication.java:

+ import com.truckmap.RNSpeech.RNSpeech;

  public class MainApplication extends Application implements ReactApplication {
    //......

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
+         new RNSpeech(),
          new MainReactPackage()
      );
    }

    ......
  }

NOTE: If you faced with this error: Could not resolve all files for configuration ':react-native-speech:debugCompileClasspath'., in build.gradle put google() in the first line (according to https://stackoverflow.com/a/50748249)

• in android/build.gradle:

allprojects {
    repositories {
+       google()
        ...
    }
}
