FastSpeech2-gronings

GroTTS Model

This model was trained with the FastSpeech 2 architecture using approx. 2 hours of Gronings TTS dataset. For the best results, you need to download the vocoder separately from here and then use the following code:

from espnet2.bin.tts_inference import Text2Speech
from scipy.io.wavfile import write

model = Text2Speech.from_pretrained(
    model_file="path_to_the_model_file_in_pth_format",
    vocoder_file="path_to_the_vocoder_file_in_pkl_format"
)
output = model("This is a simple test.")
write("x.wav", 22050, output['wav'].numpy())

The GroTTS model is deployed here.
