A smart Android teleprompter app that provides real-time script tracking and highlighting based on simulated speech recognition. Perfect for presentations, broadcasting, and public speaking.
Intelligent Teleprompter is an advanced Android application that automatically follows along with your script as you speak. It features real-time highlighting, auto-scrolling, and robust ASR (Automatic Speech Recognition) matching that can handle both English and Chinese content.
- 🎯 Real-time Highlighting: Highlights current reading position as you speak
- 🌐 Multi-language Support: Handles both English and Chinese text seamlessly
- 🤖 ASR Simulation: Built-in speech simulator for testing without microphone
- 📜 Large Script Support: Efficiently processes scripts with 100,000+ words
- 🎨 Smooth Auto-scrolling: Keeps highlighted content always visible
- 🔇 Noise Tolerance: Robust matching algorithm handles background noise and speech variations
- ⚡ High Performance: Optimized for smooth real-time operation
- Android Studio Arctic Fox or later
- Android SDK API 24+ (Android 7.0)
- Kotlin 1.8+
# Clone the repository
git clone https://github.com/yourusername/IntelligentTeleprompter.git
cd IntelligentTeleprompter
# Build and install
./gradlew installDebug- Open the app and place your script in
app/src/main/assets/script.txt - The app automatically parses and displays your script
- Start speaking and watch as the app highlights your current position
- Use the built-in ASR simulator for testing without actual speech

- ASR Matching: O(1) sliding window algorithm with configurable search window
- UI Updates: Efficient RecyclerView with partial updates and Spannable optimization
- Memory: Optimized for large scripts with pre-allocated collections
Customize the app behavior by modifying these parameters:
// ASR matching window size
val windowSize = 50 // Search forward 50 tokens
// Auto-scroll settings
smoothScroller.calculateTimeForScrolling(dx: Int): Int = 150 // Scroll duration
// Highlight colors
val highlightColor = Color.GREEN
val normalTextColor = Color.GRAY智能提词器是一款先进的Android应用程序，可以在您演讲时自动跟随脚本进度。它具备实时高亮、自动滚动和强大的ASR（自动语音识别）匹配功能，能够完美处理中英文混合内容。

- ASR匹配: O(1)滑动窗口算法，可配置搜索窗口大小
- UI更新: 高效的RecyclerView，支持部分更新和Spannable优化
- 内存: 针对大型脚本优化，使用预分配集合
通过修改以下参数自定义应用行为：
// ASR匹配窗口大小
val windowSize = 50 // 向前搜索50个词
// 自动滚动设置
smoothScroller.calculateTimeForScrolling(dx: Int): Int = 150 // 滚动持续时间
// 高亮颜色
val highlightColor = Color.GREEN // 高亮色
val normalTextColor = Color.GRAY // 普通文本色Contributions are welcome! Please feel free to submit a Pull Request.
