Speech Enhancement

Speech Enhancement API improves the quality of degraded speech recordings by removing background noise, reducing reverberation, restoring clipped audio, and performing wideband spectral reconstruction (e.g., upsampling from narrowband 2 kHz to full 44.1 kHz). The output is a high-fidelity WAV audio file with enhanced clarity, making it ideal for archiving, content enhancement, and communication in challenging acoustic environments.

语音增强API（Speech Enhancement API）可通过去除背景噪声、抑制混响、修复音频削波以及执行宽带频谱重建（例如将窄带2kHz音频上采样至完整44.1kHz），提升劣化语音录音的音质。其输出为清晰度优化的高保真WAV音频文件，非常适合用于档案归档、内容增强以及复杂声学环境下的通信场景。
