Abstract: An artificial intelligence (AI)-based audio signal generation method includes: converting a text into a corresponding phoneme sequence; encoding the phoneme sequence to obtain a contextual representation of the phoneme sequence; determining, based on a first frame hidden state corresponding to a phoneme in the phoneme sequence, an alignment position of the first frame hidden state relative to the contextual representation; decoding the contextual representation and the first frame hidden state to obtain a second frame hidden state when the alignment position corresponds to a non-end position in the contextual representation; and synthesizing the first frame hidden state and the second frame hidden state to obtain an audio signal corresponding to a text.
