# TTSDS Benchmark

As many recent Text-to-Speech (TTS) models have shown, synthetic audio can be close to real human speech.
However, traditional evaluation methods for TTS systems need an update to keep pace with these new developments.
Our TTSDS benchmark assesses the quality of synthetic speech by considering factors like prosody, speaker identity, and intelligibility.
By comparing these factors with both real speech and noise datasets, we can better understand how synthetic speech stacks up.

## More information
More details can be found in our paper [*TTSDS -- Text-to-Speech Distribution Score*](https://arxiv.org/abs/2407.12707).

## Reproducibility
To reproduce our results, check out our repository [here](https://github.com/ttsds/ttsds).

## Credits


This benchmark is inspired by [TTS Arena](https://huggingface.co/spaces/TTS-AGI/TTS-Arena) which instead focuses on the subjective evaluation of TTS models.
Our benchmark would not be possible without the many open-source TTS models on Hugging Face and GitHub.
Additionally, our benchmark uses the following datasets:
- [LJSpeech](https://keithito.com/LJ-Speech-Dataset/h)
- [LibriTTS](https://www.openslr.org/60/)
- [VCTK](https://datashare.ed.ac.uk/handle/10283/2950)
- [Common Voice](https://commonvoice.mozilla.org/)
- [ESC-50](https://github.com/karolpiczak/ESC-50)
