Microsoft has unveiled a fascinating neural model called VALL-E, which can synthesize speech based on a text prompt and three-second audio. While text-to-speech (TTS) synthesis is nothing new, the fact that AI needs so little time to create a believable recording is astounding.
According to the paper, the researchers trained the neural codec language model on 60K hours of English speech, which resulted in VALL-E "significantly outperforming the state-of-the-art zero-shot TTS system in terms of speech naturalness and speaker similarity."
The model can even preserve the speaker's emotion and the acoustic environment of the original audio prompt.
