Usage

Dependencies

• Step 1. Add the JitPack repository to your project build.gradle:

      allprojects {
  	    repositories {
  		    ...
  		    maven { url 'https://jitpack.io' }
  	    }
      }

  or

  If Android studio version is Arctic Fox then add it in your settings.gradle:

     dependencyResolutionManagement {
  		repositories {
      		...
      		maven { url 'https://jitpack.io' }
  		}
     }

• Step 2. Add the dependency in your app module build.gradle:

      dependencies {
          ...
          implementation 'com.github.Mindinventory:AutoHighlightTTS:X.X.X'
      }

Implementation

• Step 1. Initialization of the MiTextToSpeech inside your viewmodel :

  ...
  
     lateinit var instanceOfTTS: AutoHighlightTTSEngine
  
    init {
        initTTS(context)
    }
  
    private fun initTTS(context: Context): AutoHighlightTTSEngine {
        instanceOfTTS = AutoHighlightTTSEngine
            .getInstance()
            .init(context)
            .setLanguage(Locale.ENGLISH)
            .setPitchAndSpeed(1f, 1f)
            .setText(context.getString(R.string.text_to_speech_text))
        return instanceOfTTS
    }
  
  ... 

• Step 2. Add listeners and MITextToSpeechText inside your composable :

  ...
    
         var instanceOfTTS by remember {
            mutableStateOf<AutoHighlightTTSEngine?>(null)
        }
  
        LaunchedEffect(instanceOfTTS == null) {
            instanceOfTTS = viewModel.instanceOfTTS
        }
  
  ...
  
        // Listeners to get status
  
        tts.setOnCompletionListener {
            Log.e("TAG", "TTSScreen: Completed From Callback")
        }.setOnErrorListener {
            //Perform action for error
        }.setOnEachSentenceStartListener {
            Log.e("TAG", "TTSScreen: onEachSentenceStart is called")
        }
  
  
  ...
  
    // The composable function displays the text and helps us to highlight the currently spoken sentence.
  
        TTSComposable(
            tts = tts,
            textAlign = TextAlign.Center,
            fontFamily = fontFamily,
            fontWeight = FontWeight.ExtraLight,
            miTextHighlightBuilder = MITextHighlightBuilder(
                text = tts.mainText,
                tts.highlightTextPair.value,
                style = SpanStyle(
                      fontFamily = fontFamily,
                      color = Amaranth,
                      fontWeight = FontWeight.Bold,
                    )
                ),
            style = TextStyle(
                fontSize = 20.sp, color = Color.Black,
                lineHeight = 35.sp
            ),
        )
  
  ...
