Abstract
Embodiments of the disclosure provide a speech signal encoding and decoding methods and apparatuses, an electronic device, and a computer-readable storage medium. The decoding method includes: obtaining a bitstream including a first substream, and the first substream being a bitstream obtained by encoding a low-frequency subband signal of an original speech signal by using a first encoding method; and performing signal reconstruction based on the first substream in a case that the bitstream includes no second substream, to obtain a reconstructed speech signal; or performing signal reconstruction based on the first substream and at least one second substream in a case that the bitstream includes the at least one second substream, to obtain a reconstructed speech signal, each second sub stream being obtained by encoding a high-frequency subband signal of the original speech signal, and the encoding being performed by using a second encoding method corresponding to the each second substream.
