It includes synthetic audio generated by commercial TTS services, open-source models, and Chinese TTS websites. An equal amount of bonafide speech from CommonVoice is included for a 1:1 balance between genuine and spoofed samples. This dataset is designed to support research and model training for audio anti-spoofing. - 📥 [Download on huggingface](https://huggingface.co/datasets/jhsdfbsdjfu/MultiAPI-Spoof) - 🖥️ [Code on github](https://github.com/kjsdhsjkhckjsa/MultiAPI-Spoof) - 🤗 [Model on huggingface](https://huggingface.co/jhsdfbsdjfu/Nes2Net_LA) *** ## Spoofed Audio Data Sources Our new dataset, **MultiAPI Spoof**, contains speech samples generated from a variety of API sources, including: 1. **Commercial TTS APIs** – speech generated by commercial services. 2. **Open-Source Model Generation** – speech generated by open-source models. 3. **TTS Websites** – speech on TTS web platforms. The dataset is organized into 30 API, labeled **A0–A29**, with each group corresponding to a unique speech generation API source. The duration of speech in each API ranges from **0.2 to 12 hours**. *** ## Dataset Split | API NO. | train | dev | eval | | :------ | :---- | :--- | ---- | | A0-A20 | 70% | 10% | 20% | | A21-A23 | / | 100% | / | | A24-A29 | / | / | 100% | *** ## Metadata The dataset includes three metadata files: MultiAPI`_train.txt`, MultiAPI`_dev.txt`, and MultiAPI`_eval.txt`. Each line has four fields: audio_path api class_label XXX.mp3 A0 spoofed XXX.mp3 - bonafide ## 📖 Citation If you use this code or dataset, please cite: ``` Anonymous ``` *** ## 📧 Contact Anonymous *** ## 🔏 License The dataset is released under [CC BY-NC 4.0](https://creativecommons.org/licenses/by-nc/4.0/deed.en) license.
