Double talk algorithm integrating echo cancellation and speech enhancement techniques for accurate speech endpoint detection in noisy environments

Detailed Documentation

The double talk algorithm that combines echo cancellation and speech enhancement methods can accurately determine speech start and end points in noisy environments while improving speech signal clarity and audibility. This implementation typically involves adaptive filtering for echo cancellation followed by spectral subtraction or Wiener filtering for speech enhancement.

In practical applications, the double talk algorithm serves as an effective technique for processing speech signals in challenging acoustic conditions. The algorithm employs voice activity detection (VAD) modules and cross-correlation analysis to distinguish between near-end and far-end speech, ensuring better speech quality and improved user experience through real-time signal processing.
