语音测试WAV噪声库.zip

应用于语音识别数据加噪的数据，这里面包含了各种噪声，kaldi下面thchs30里面有具体的加噪代码，增加噪声可以使得声学模型更具有鲁棒性。有兴趣的可以尝试。

各种不同环境下噪声库

noizeus数据库，这个语音库有纯净的语音和不同信噪比的带噪语音，但是没有纯噪声。

Noise_92噪声库的文件，包含了15个纯噪声数据，可以用于做语音增强算法的研究

含有十五种噪声，Noise data White noise Pink noise HF channel noise Speech babble Factory floor noise 1 Factory floor noise 2 Jet cockpit noise 1 Jet cockpit noise 2 Destroyer engine room noise Destroyer operations room noise F-16 cockpit noise Military vehicle noise Tank noise Machine gun noise Car interio

音频分析里面常用的噪声库

很有用的噪声库，可进行语音信号处理的离线仿真测试等 File: Matlab or WAV formats (compressed) sampling rate: 19.98 KHz A/D: 16 bit pre-filter: anti-aliasing filter pre-emphasis: none filter: none duration: 235 sec length (uncompressed): approx 9 Mb (uncompressed) 白噪声：White noise White Noise acquired by sampling high-quality analog noise generator (Wandel & Goltermann). Exhibits equal energy per Hz. bandwidth. 车内噪声：volvo Volvo 340 noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). This recording was made at 120 km/h, in 4th gear, on an asphalt road, in rainy conditions. 军用车辆噪音：Military vehicle noise Leopard 2 noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). The Leopard 1 vehicle was moving at a speed of 70 km/h. The sound level during the recording process was 114 dBA. 坦克内部噪声:Tank noise M109 noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). The M109 tank was moving at a speed of 30 km/h. The sound level during the recording process was 100 dBA. 餐厅内嘈杂噪声：speech babble Voice Babble acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). The source of this babble is 100 people speaking in a canteen. The room radius is over two meters; therefore, individual voices are slightly audible. The sound level during the recording process was 88 dBA. 高频信道噪声：HF channel noise Recording of noise in an HF radio channel after demodulation 粉红噪声：pink noise Pink Noise acquired by sampling high-quality analog noise generator (Wandel & Goltermann). Exhibits equal energy per 1/3 octave. 机枪噪声：Machine gun noise Machine Gun noise acquired by recording samples from 1/2" B&K condensor microphone onto digital audio tape (DAT). The weapon used was a .50 calibre gun fired repeatedly. 工厂车间噪音1：Factory floor noise 1 Factory noise acquired by recording samples from 1/2" B&K condensor

含有 NoiseX-92噪声库-完整版,包含15种音频文件，每种包含mat,wav两种格式。wav采样率为16khz,单声道

这些非语音的环境声音可以用作评估语音分离系统等的非语音噪声。
