Embodiment Construction
[0040] In order to make the purposes, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments These are some, but not all, embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present disclosure.
[0041] The audio sampling rate refers to how much the recording equipment samples the analog signal per unit time. The higher the sampling frequency, the more realistic and natural the waveform of the mechanical wave is. There are five levels of 24000Hz, 44100Hz and 48000Hz. 11025Hz can achieve the sound quality of AM broadcast, while 22050Hz and...

The present disclosure relates to a speech detection method and device, electronic equipment and a storage medium. The method includes: extracting acoustic features of the speech to be detected to obtain the first acoustic feature and the second acoustic feature; inputting the first acoustic feature sequence The pre-trained sampling rate prediction model obtains the sampling rate information features; the second acoustic feature and sampling rate information features are input into the pre-trained speech detection model to obtain the classification result of the speech to be detected as real speech or synthetic speech, combined with sampling The rate information features are used to detect the speech to be detected, which can quickly judge the audio quality of the audio in the actual scene, help the speech detection model to identify different frequency bands of the actual audio more focused, and avoid false high-frequency speech from interfering with the model discrimination. Improve the classification accuracy of the detection model.
Description
technical field [0001] The present disclosure relates to the field of speech technology, and in particular, to a speech detection method and device, an electronic device, and a storage medium. Background technique [0002] At present, in order to capture more discriminative information, speech detection models use a variety of acoustic features for speech signal processing. However, in the actual application process of speech detection, there is a situation that the nominal audio sampling rate of the speech to be detected is different from the actual audio sampling rate, which leads to the problems of insufficient robustness and low precision of speech detection. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problem or at least partially solve the above technical problem, the embodiments of the present disclosure provide a voice detection method and apparatus, an electronic device, and a storage medium. [0004] In a first aspect, an embodiment o...
