+# 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**.

+## 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
