This repository provides all the necessary tools to perform TTS quality evaluation using a WavLM finetuning model. The model
attempts to predict the Mean Opinion Score, i.e. averaged human ratings on a scale from 1 to 5.
For a better experience, we encourage you to learn more about
SpeechBrain. The model performance on SOMOS test set is:

Pipeline description
This system is composed of an WavLM model and a simple forward transformer followed by statistical pooling. The model was trained by first pre-conditioning the model on a simple classifier that attempts to determine whether the rating is above a certain threshold and then fine-tuned on the regression task.
Install SpeechBrain
First of all, please install the development version of SpeechBrain with the following command:
The prediction is a SpeechEvaluationResult named tuple instance where prediction.score and
predictions.details["score"] both indicate the predicted Mean Opinion Score.
Inference on GPU
To perform inference on the GPU, add run_opts={"device":"cuda"} when calling the from_hparams method.
cd speechbrain
pip install -r requirements.txt
pip install -e .
Run Training:
cd recipes/SOMOS/ttseval
python train.py hparams/train.yaml --data_folder=your_data_folder
Limitations
The SpeechBrain team does not provide any warranty on the performance achieved by this model when used on other datasets.
