推荐答案

如果这表示我认为的意思，请不要打扰.
语音识别很困难，所以当歌手将他们的声音遍及整个频谱，出现背景噪音等时，您希望能够做到这一点.

Althoug您只需要单词计数而不是实际单词，在歌曲2个或更多单词中，它们通常是无缝地混合在一起的，因此，如果您想使其准确，就需要对语言有一定的了解.

我不是音频分析方面的专家，但我要做的是首先删除声带范围之外的所有频率，也许使用 FFT [ ^ ]，然后尝试应用语音识别 [

If this means what I think it means, then don''t bother.
Speech recognition is difficult, then you want to be able to do it when the singer is putting their voice all through the spectrum, you have background noises, etc...

Althoug you only want the word count and not the actual words, in song 2 or more words often blend together seamlessly, so if you want it to be accurate you would need it to have some understanding of language.

I''m no pro on audio analysis, but what I would do is start by removing all the frequencies outside of the vocal range perhaps with a FFT[^], then try to apply a speech recognition[^] system over that.
