# TTS Engine
A simple and efficient library that provides Text-to-Speech functionality for Android applications.
## Features
- Support for multiple languages and voices
- Easy-to-use API
## Installation
Add the library to your project using Gradle:
```groovy
allprojects {
repositories {
maven { url 'https://jitpack.io' }
}
}
```
```groovy
dependencies {
implementation 'com.github.aiyu-ayaan:tts-engine:Tag'
}
```
## Usage
Using the library is straightforward and simple. Here is an example of how to use it in your code:
```kotlin
TextToSpeechHelper
.getInstance(activity)
.registerLifecycle(owner)
.speak(message)
.highlight()
.onHighlight { pair ->
Log.d(TAG, "speak: ${pair.first} - ${pair.second}")
}
.onDone {
Log.d(TAG, "speak: done")
}
.onError {
Log.d(TAG, "speak: $it")
}
```
- `activity` is the activity that will be used to initialize the TTS engine.
- `owner` is the lifecycle owner that will be used to register the TTS engine lifecycle observer and can handle the lifecycle events.
- `message` is the text that will be spoken.
- `highlight()` is an optional method that will highlight the spoken words in the text.
- `onHighlight()` is an optional method that will be called when a word is spoken.
- `onDone()` is an method that will be called when the text is spoken.
- `onError()` is an method that will be called when an error occurs.
## Code Example
### For Jetpack Compose, check out the example below:
`MainActivity.kt`
```kotlin
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
TTSLibraryTheme {
val viewModel = MainViewModel()
val resource = stringResource(id = R.string.des)
val text = remember { resource }
// screen
Surface(
modifier = Modifier.fillMaxSize(),
color = MaterialTheme.colorScheme.background
) {
Screen(
state = text,
viewModel = viewModel,
) {
speak(
this,
this as LifecycleOwner,
text,
viewModel
)
}
}
}
}
}
}
@Composable
fun Screen(
modifier: Modifier = Modifier,
viewModel: MainViewModel,
state: String,
onButtonClick: () -> Unit = {},
) {
Column(
modifier = modifier
.fillMaxSize()
.padding(16.dp),
verticalArrangement = Arrangement.Center,
horizontalAlignment = Alignment.CenterHorizontally
) {
val s = viewModel.getState().value
TTSText(
textAlign = TextAlign.Center,
textHighlightBuilder = TextHighlightBuilder(
text = state,
s
),
)
Spacer(modifier = Modifier.padding(16.dp))
Button(onClick = onButtonClick) {
Text(text = stringResource(id = R.string.speak))
}
}
}
private fun speak(
activity: Activity,
owner: LifecycleOwner,
message: String,
viewModel: MainViewModel
) {
TextToSpeechHelper
.getInstance(activity)
.registerLifecycle(owner)
.speak(message)
.highlight()
.onHighlight { pair ->
viewModel.updateState(pair)
}
.onDone {
Log.d(TAG, "speak: done")
}
.onError {
Log.d(TAG, "speak: $it")
}
}
```
`MainViewModel.kt`
```kotlin
class MainViewModel : ViewModel() {
private val state = mutableStateOf(Pair(0, 0))
fun updateState(pair: Pair) {
state.value = pair
}
fun getState(): State> = state
}
```
### For XML layouts, check out the example below:
```kotlin
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val textView = findViewById(R.id.text_view)
val button = findViewById(R.id.button)
val message = getString(R.string.des)
button.setOnClickListener {
speak(
this,
this as LifecycleOwner,
message,
textView
)
}
}
private fun speak(
activity: Activity,
owner: LifecycleOwner,
message: String,
textView: TextView
) {
TextToSpeechHelper
.getInstance(activity)
.registerLifecycle(owner)
.speak(message)
.highlight()
.onHighlight { pair ->
textView.highlightText(pair.first, pair.second)
}
.onDone {
Log.d(TAG, "speak: done")
}
.onError {
Log.d(TAG, "speak: $it")
}
}
}
```
- `TextView.highlightText()` is an extension method that highlights the spoken words in the text.
