卡拉OK機器如何為您的歌唱評分?

People in karaoke often compare their singing scores with the others, but little did they know that those karaoke machines never really tell the true score. In fact, people mistake themselves as better singers as the karaoke machine gave them a higher score. So how do karaoke machines actually score your singing?

Input is all that matters

Truth to be told, those karaoke machines only consider the input when you sing. In other words, if you sing at the correct moment when the lyrics appears on the screen with a loud voice, it will show you higher score.

Theoretically, the karaoke machine score your singing by comprising the following steps:

  1. detecting frame energy of a Karaoke singer’s singing voice singing to pre-recorded music in the karaoke machine

  2. detecting frame enegery of an original artist’s singing voice on the pre-recorded music

The more the frame energy of the karaoke singer match the frame energy of the original artist, a more higher score will be given.

Hence, Never trust singing scores given by karaoke machines !

唱卡拉OK的人經常將他們的歌唱分數與其他人比較,但他們大多都不知道這些卡拉OK機打的從來不是真實的分數。事實上,人們都把自己誤認為是更好的歌手,是因為卡拉OK機給了他們較高的分數。那麼卡拉OK機是如為你的歌唱打分的呢?

聲音的輸入是評分的最大標準

說實話,那些卡拉OK機只在你唱歌時只會評核你聲音的輸入。換句話說,如果你在歌詞出現時並大聲地唱出正確的歌詞,機器就會顯示一個更高的分數。

從理論上講,卡拉OK機通過以下步驟為您的歌唱打分:

  1. 檢測卡拉OK歌手唱歌聲的聲音能量,再將其能量跟在卡拉OK機中預先錄製音樂的聲音能量作對比。

  2. 在預先錄製的音樂中檢測原唱者的歌聲的聲音能量,並作對比。

如果卡拉OK歌手的聲音能量與原唱著的聲音能量相匹配得越多,卡拉OK機就會給予更高的分數。

所以,永遠不要相信卡拉OK機打的歌唱分數!
