      Voiceprint

      聲紋

       

      A display of a person’s voice based upon a spectrographic or similar output. The analogy is with the term ‘fingerprint’, and the claim is sometimes made that a person’s voice is as individual fingerprints. Several legal cases have in fact used voiceprints as evidence of speaker identification. But, while there are several idiosyncratic features in a spectrogram of a person’s voice, it is not the case that such displays are always unequivocal indications of identity. It is difficult to visually compare and interpret sets of spectrographic features, and the limitations of the display techniques used must always be borne in mind.

       

      依靠頻譜儀和類似儀器的輸出來顯示的個人的嗓音;系仿照“指紋”一語而來。有人認為每個人的嗓音和指紋一樣都不同于其他人;有一些司法案件也確實用聲紋來作說話人認同的證據。但是,個人嗓音的頻譜儀圖雖然有一些與眾不同的特征,并不總能確定無疑地識別一個人的身份??恳曈X很難比較和解釋一組組頻譜儀圖特征,因此必須隨時提醒這種顯示技術的局限性。
