| 摘要 |
The embodiments of the present invention provide a method, an apparatus, and an access network system for speech signal processing. The speech signal processing method includes: receiving an encoded speech signal sent by a user equipment UE, where the encoded speech signal includes a first substream, a second substream, and a third substream, and the first substream includes a cyclic redundancy check CRC; performing decoding processing on the first substream, the second substream, and the third substream by adopting a decoding algorithm, where a decoding algorithm that is based on an auxiliary decision of the CRC is adopted to perform decoding processing on the first substream; and sending decoding results of the first substream, the second substream, and the third substream to a base station controller, where the decoding result of the first substream includes a decoded bit stream and a CRC result. The embodiments of the present invention can improve decoding performance of the first substream to improve speech quality and meet users' higher requirements for the speech quality. |
