Re-train existed models on augmented data

[margaritatsobenko]

Models:

• SVM
• Tacotron encoder
• XGBoost
• Neural network

[margaritatsobenko]

To improve Tacotron's results (to minimize variation of confidence interval of scores) try to change hyperparameters (convolution params, LSTM params...). NB: It's better to have the same params for each convolution layer.
