Embodiment Construction

[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0063] Figure 1A and Figure 1B It is a schematic screenshot of an abnormal detection result of detecting a speech signal in the related art. in, Figure 1A It is the detection result manually calibrated by comparing with the original speech, Figure 1B It is the detection result of the prior art. Figure 1A and Figure 1B In , the horizontal axis represents the sample points, and the vertical axis represents the normalized amplitude. For the short-dur...

Abstract

The present invention discloses a method and an apparatus for detecting a voice signal. The method includes: performing, in a unit of first timeframe frame length, framing on a continuous voice sample to obtain a plurality of first timeframes, detecting energy of each of the first timeframes, and determining a target first timeframe including a potential abrupt exception of a voice signal by analyzing a relationship between the energy of the plurality of first timeframes; performing, in a unit of second timeframe frame length, framing on the continuous voice sample to obtain a plurality of second timeframes, where each second timeframe frame length is an integral multiple of the first timeframe frame length, and a second timeframe including the target first timeframe is a target second timeframe; and processing each of the second timeframes to acquire a tone feature, and determining, by analyzing a tone feature of at least one of the second timeframes including at least one target second timeframe, whether the potential abrupt exception of a voice signal included in the target first timeframe included in the target second timeframe is a real abrupt exception of a voice signal. The technical solution can improve accuracy in detecting an abrupt exception of a voice signal.

Description

technical field [0001] The present invention relates to the field of audio processing, and more particularly, to a method and device for detecting speech signals. Background technique [0002] In audio technology, for the convenience of analysis, the abnormal start (abrupt start in English) and / or abnormal end (abrupt stop in English) of the speech signal indicates two types of situations in this paper: one is that it appears in the same speech segment Abnormal end and abnormal start in pairs of short duration, referred to in this context as abnormal discontinuity. For example, in the process of speaking, if a piece of speech signal loses some information in the middle, it will cause abnormal interruption. The other is a single abnormal start or a single abnormal end, which is simply referred to as abnormal start or abnormal end in the context. For example, an abnormal start of the speech signal when starting to speak, or an abnormal end of the speech signal when ending sp...
