Fake audio detection is a growing concern and some relevant datasets have been designed for research. But there is no standard public Chinese dataset under additive noise conditions. In this paper, we aim to fill in the gap and design a Chinese fake audio detection dataset (FAD) for studying more generalized detection methods. Twelve mainstream speech generation techniques are used to generate fake audios. To simulate the real-life scenarios, three noise datasets are selected for noisy adding at five different signal noise ratios. FAD dataset can be used not only for fake audio detection, but also for detecting the algorithms of fake utterances for audio forensics. Baseline results are presented with analysis. The results that show fake audio detection methods with generalization remain challenging. The FAD dataset is publicly available. The source code of baselines is available on GitHub https://github.com/ADDchallenge/FAD The FAD dataset is designed to evaluate the methods of fake audio detection and fake algorithms recognition and other relevant studies. To better study the robustness of the methods under noisy conditions when applied in real life, we construct the corresponding noisy dataset. The total FAD dataset consists of two versions: clean version and noisy version. Both versions are divided into disjoint training, development and test sets in the same way. There is no speaker overlap across these three subsets. Each test sets is further divided into seen and unseen test sets. Unseen test sets can evaluate the generalization of the methods to unknown types. It is worth mentioning that both real audios and fake audios in the unseen test set are unknown to the model. For the noisy speech part, we select three noise database for simulation. Additive noises are added to each audio in the clean dataset at 5 different SNRs. The additive noises of the unseen test set and the remaining subsets come from different noise databases. In each version of FAD dataset, there are 138400 utterances in training set, 14400 utterances in development set, 42000 utterances in seen test set, and 21000 utterances in unseen test set. More detailed statistics are demonstrated in the Tabel 2. Clean Real Audios Collection From the point of eliminating the interference of irrelevant factors, we collect clean real audios from two aspects: 5 open resources from OpenSLR platform (http://www.openslr.org/12/) and one self-recording dataset. Clean Fake Audios Generation We select 11 representative speech synthesis methods to generate the fake audios and one partially fake audios. Noisy Audios Simulation Noisy audios aim to quantify the robustness of the methods under noisy conditions. To simulate the real-life scenarios, we artificially sample the noise signals and add them to clean audios at 5 different SNRs, which are 0dB, 5dB, 10dB, 15dB and 20dB. Additive noises are selected from three noise databases: PNL 100 Nonspeech Sounds, NOISEX-92, and TAU Urban Acoustic Scenes. This data set is licensed with a CC BY-NC-ND 4.0 license.
