Speech Endpoint Detection Program

The speech endpoint detection program included in J.S. Roger Jang's "Audio Processing and Recognition" book presents fascinating and practical content for audio signal processing. This program demonstrates how to effectively identify the starting and ending points of speech segments within audio signals, utilizing key algorithms such as short-term energy analysis and zero-crossing rate calculations. The implementation typically involves frame-based processing where the audio signal is divided into short overlapping frames, followed by feature extraction and threshold-based decision making. The book provides comprehensive guidance and working code examples that allow readers to deeply understand the principles and practical applications of voice activity detection. Whether you're a beginner exploring speech processing or a professional developer working on speech recognition systems, this material offers valuable insights into implementing robust endpoint detection algorithms that significantly improve speech recognition accuracy by effectively separating speech segments from background noise.
