Abstract: Example methods and apparatus for providing voice alignment are described. One example method including: obtaining an original voice and a test voice, the test voice is a voice generated after the original voice is transmitted over a communications network; performing loss detection and/or discontinuity detection on the test voice, the loss detection is used to determine whether the test voice has a voice loss compared with the original voice, and the discontinuity detection is used to determine whether the test voice has voice discontinuity compared with the original voice; and aligning the test voice with the original voice based on a result of the loss detection and/or the discontinuity detection, to obtain an aligned original voice and an aligned test voice, the result of the loss detection and/or the discontinuity detection is used to indicate a manner of aligning the test voice with the original voice.

Abstract: Signaling analysis methods and apparatus are provided to obtain a to-be-detected signaling flow that includes N pieces of signaling. First feature construction is performed on a message type and an information element that are included in each of the N pieces of signaling to obtain a first feature sequence. The first feature sequence includes N first feature vectors which are in a one-to-one correspondence with the N pieces of signaling. The first feature sequence is input to a first signaling anomaly detection model to perform anomaly detection processing. A first anomaly detection result is produced indicating that the to-be-detected signaling flow is normal or abnormal. In this way, an anomaly caused due to an information element error can be covered. The method and the apparatus can be multiplexed between different protocols.
