The present disclosure provides an audio data processing method and apparatus, an electronic device, a computer-readable storage medium and a computer program product and relates to the field of artificial intelligence, in particular to an audio processing technology. An implementation solution is: obtaining human voice audio data to be adjusted and reference human voice audio data, wherein the reference human voice audio data and the human voice audio data to be adjusted are obtained based on the same text information; performing framing on the human voice audio data to be adjusted and the reference human voice audio data respectively so as to obtain a first audio frame set and a second audio frame set respectively; recognizing a pronunciation unit corresponding to each audio frame respectively; determining, based on a timestamp of each audio frame, a timestamp of each pronunciation unit in the human voice audio data to be adjusted and the reference human voice audio data respectively; and adjusting the timestamp of at least one pronunciation unit in the human voice audio data to be adjusted to make the timestamp of the pronunciation unit in the human voice audio data to be adjusted to be consistent with the timestamp of the corresponding pronunciation unit in the reference human voice audio data.
