这是合成美国航空管制语音的VHF AM航空信道降级变体。每条记录对应一个干净语音片段及其变体，内嵌8 kHz单声道PCM_16 WAV音频。该数据集是干净数据集的噪声版本，通过概率性信道模拟流程处理，模拟了ATCO2语料库的信噪比分布（均值约8 dB，范围-5至+30 dB）和ITU-R M.1084 / DO-186B航空语音通带特性（300-3400 Hz，六阶巴特沃斯滤波器）。数据集包含3,365,754条噪声记录，由1,121,918个干净语音片段生成3个独立信道变体。VHF AM aviation channel-degraded variants of synthesized US air-traffic-control speech. One row per (clean turn × variant), embedded 8 kHz mono PCM_16 WAV. This is the noisy variant of the clean dataset — same transcripts and voices, passed through a probabilistic channel-simulation pipeline calibrated to the ATCO2 corpus SNR distribution (mean ~8 dB, range -5 to +30 dB) and shaped to ITU-R M.1084 / DO-186B aero voice passband (300-3400 Hz, 6th-order Butterworth).
