Embodiment Construction

[0051] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0052] see figure 1 , figure 1 It is a schematic diagram of a model of a digital baseband communication system applicable to an embodiment of the present invention, such as figure 1 As shown, the process of voice data transmission from the source to the sink includes: analog-to-digital conversion, source coding, channel coding, channel transmission, channel decoding, source decoding and digital-to-analog conversion, wherein, in the process of channel transmission, often There will be noise sources added. In addition, the information source can be understood as the voice data publisher or the voice data sending end, and the information sink can be understood as the voice data receiver or the voice data receiving end.

[0053] In addition, in the embodi...

Abstract

The invention provides a voice problem positioning method and device. The method comprises steps that to-be-analyzed voice data is acquired, and the to-be-analyzed voice data is analyzed to acquire analyzed voice data; the corresponding relationship of each voice frame including the source frame number information of the analyzed voice data is established; problem frames with voice problems of theanalyzed voice data are searched; the result information including the source frame number relationship of the problem frames is outputted. The method is advantaged in that the problem frames with the voice problems can be rapidly positioned, and the voice problem positioning speed is enhanced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for locating voice problems. Background technique [0002] When analyzing terminal voice problems, locating the voice problem often requires analyzing a large amount of data to locate the voice problem, that is, to find out the voice problem. For example: Take narrowband as an example, the sampling frequency is 8000Hz, 20 milliseconds (ms) is one frame, and there are 50 frames in one second. Voice tests are usually measured in hours, and there is often a time difference of a few seconds or even tens of seconds or minutes when the problem is reported, which may require a few minutes of searching before and after the problem point to locate the problem when analyzing the problem. Speech problems, that is to say, thousands to tens of thousands of frames of data need to be analyzed. And now when analyzing voice problems, it is usually based on the local s...
