adaptive speech enhancement的用法和样例：
- Based on the idea of adaptive noise cancellation (ANC), a new second-order feedforward architecture was proposed for speech enhancement.
- In the presence of additive white Gaussian noise, an adaptive wavelet-based de-noising algorithm for speech enhancement applications is proposed.
- An adaptive noise cancellation method is presented to extract desired signal from array cross talk signals, and is used to microphone array speech enhancement.
- Simulation results demonstrate the method is very effective in speech enhancement.
- A method based on fractional spectral subtraction for speech enhancement (FSS) is proposed.
