# MultiAPI Spoof: Multi-Source Audio Anti-Spoofing Dataset
## Introduction
MultiAPI-Spoof is a multi-source audio anti-spoofing dataset that contains approximately 230 hours of spoofed audio. 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.

## 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**.
