+# 4TTSDeepfakeDataset
+
+## Description
+Based on the [Hi-Fi Multi-Speaker English TTS Dataset](https://www.openslr.org/109/), this dataset includes 148.06 hours and 75,575 utterances of 24kHz Mono 16-bit audio. It uses the utterances of speakers 6097, 6670, 6671, and 9017 from the original corpus.
+
+For each original bona fide utterance, there are 4 corresponding deepfake zero-shot 1:1 utterances generated by the following models (15,115 utterances each):
+* [F5-TTSv1](https://huggingface.co/SWivid/F5-TTS)
+* [MaskGCT](https://huggingface.co/amphion/MaskGCT)
+* [CosyVoice2](https://huggingface.co/FunAudioLLM/CosyVoice2-0.5B)
+* [Fish-S1mini](https://huggingface.co/fishaudio/s1-mini)
+
+## Dataset Structure
+The dataset includes 5 folders with utterances and a `parallel_manifest.json` file that provides the 1:4 (bona fide to TTS deepfakes) mapping.

+**Modifications to the Original Material:** 1. The original bona fide audio files from speakers 6097, 6670, 6671, and 9017 were modified (sliced and merged) to create the parallel baseline utterances.
+2. These preprocessed bona fide files were then used as the source material to generate 1:1 synthetic speech (deepfakes).
+
+### Synthetic Data Generation (Deepfakes)
+The synthetic deepfake utterances in this dataset were generated using the following open-source Text-to-Speech models. The generated audio inherits the licensing terms of their respective source models:
