By pre-training on text and speech at the same time, it learns unified representations for both, resulting in improved modeling capabilities. SpeechT5 can be fine-tuned for different speech tasks. This space demonstrates the text-to-speech (TTS) checkpoint for the English language. See also the speech recognition (ASR) demo and the voice conversion demo. How to use: Enter some English text and choose a speaker. The output is a mel spectrogram, which is converted to a mono 16 kHz waveform by the HiFi-GAN vocoder. Because the model always applies random dropout, each attempt will give slightly different results. The Surprise Me! option creates a completely randomized speaker. """ article = """
