A speech data processing method, performed by a server, the method comprising: receiving first speech data transmitted by a sender and obtaining a speech enhancement parameter; performing speech enhancement on the first speech data based on the obtained speech enhancement parameter to obtain first speech enhancement data, and determining a first speech enhancement parameter based on the first speech data; and transmitting the first speech enhancement data to a recipient, and updating the obtained speech enhancement parameter by using the first speech enhancement parameter to obtain an updated speech enhancement parameter, wherein the updated speech enhancement parameter is used for performing, in a case that second speech data transmitted by the sender is received, speech enhancement on the second speech data based on the updated speech enhancement parameter, wherein in a case that the speech enhancement parameter corresponding to the sender is not obtained, the performing speech enhancement on the first speech data based on the obtained speech enhancement parameter to obtain first speech enhancement data comprises: obtaining a preset speech enhancement parameter, performing speech enhancement on the first speech data based on the preset speech enhancement parameter to obtain the first speech enhancement data, performing feature sequence processing on the first speech data by using a trained speech enhancement model to obtain a first speech feature sequence, the speech enhancement model being provided with the preset speech enhancement parameter; performing batch processing calculation on the first speech feature sequence by using the preset speech enhancement parameter to obtain a processed first speech feature sequence and the first speech enhancement parameter; and performing feature inverse transformation processing on the processed first speech feature sequence to obtain the first speech enhancement data. receiving first speech data transmitted by a sender and obtaining a speech enhancement parameter; performing speech enhancement on the first speech data based on the obtained speech enhancement parameter to obtain first speech enhancement data, and determining a first speech enhancement parameter based on the first speech data; and transmitting the first speech enhancement data to a recipient, and updating the obtained speech enhancement parameter by using the first speech enhancement parameter to obtain an updated speech enhancement parameter, wherein the updated speech enhancement parameter is used for performing, in a case that second speech data transmitted by the sender is received, speech enhancement on the second speech data based on the updated speech enhancement parameter, wherein in a case that the speech enhancement parameter corresponding to the sender is not obtained, the performing speech enhancement on the first speech data based on the obtained speech enhancement parameter to obtain first speech enhancement data comprises: obtaining a preset speech enhancement parameter, performing speech enhancement on the first speech data based on the preset speech enhancement parameter to obtain the first speech enhancement data, performing feature sequence processing on the first speech data by using a trained speech enhancement model to obtain a first speech feature sequence, the speech enhancement model being provided with the preset speech enhancement parameter; performing batch processing calculation on the first speech feature sequence by using the preset speech enhancement parameter to obtain a processed first speech feature sequence and the first speech enhancement parameter; and performing feature inverse transformation processing on the processed first speech feature sequence to obtain the first speech enhancement data. obtaining a preset speech enhancement parameter, performing speech enhancement on the first speech data based on the preset speech enhancement parameter to obtain the first speech enhancement data, performing feature sequence processing on the first speech data by using a trained speech enhancement model to obtain a first speech feature sequence, the speech enhancement model being provided with the preset speech enhancement parameter; performing batch processing calculation on the first speech feature sequence by using the preset speech enhancement parameter to obtain a processed first speech feature sequence and the first speech enhancement parameter; and performing feature inverse transformation processing on the processed first speech feature sequence to obtain the first speech enhancement data.
