The invention provides a silent anomaly detection method and a corresponding device in a voice call, and the method comprises the steps: obtaining at least one audio stream of an opposite end in a voice call process, and carrying out the continuous blank frame counting of a voice frame of each audio stream; for each audio stream, if the current voice frame is a target voice frame, acquiring a current continuous blank frame count value; if the continuous blank frame count value is not less than the preset value, acquiring the on-off state of the voice acquisition equipment of the corresponding opposite end; if the voice acquisition device at the opposite end is in the on state, determining that the corresponding audio stream in the voice call has silent abnormity; and determining whether there is a silent abnormality in the audio stream or not by combining the number of continuous blank frames in the audio stream of the opposite end and the on-off state of the voice acquisition device of the opposite end. The method is used for prompting system operation and maintenance personnel to timely monitor possible terminal and background service defects in a voice communication system.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular, the present application relates to a silent abnormality detection method and a corresponding device in a voice call. Background technique [0002] During voice calls, especially multi-person voice calls, voice quality is crucial to user experience and is an operational indicator that voice call system providers focus on. Due to the differences in the terminal equipment used by users to access the voice communication system, as well as the complex and changeable environment in which users live, voice quality problems often occur. Common voice quality problems include: silence, noise, acoustic echo, howling and other abnormalities. Among them, the silent anomaly is the most serious. [0003] Existing voice quality detection in voice calls can only determine whether there is a voice quality problem, but cannot clarify what kind of voice quality problem the existing vo...
