      Speaker Recognition/Identification/Verification

      說話人識別/認同/驗證

       

      In phonetics and computational linguistics, speaker recognition is the acoustic analysis of a speech sample to infer the identity of the speaker. In speaker verification, a sample of speech is acoustically analysed to check a claimed identity against a stored reference sample stored in the computer. In speaker identification, a speech sample from a known speaker is compared to one obtained from an unknown speaker, to determine whether the same person is involved. This technique has been most commonly used in criminal cases, where the analysis of spectrograms (as in voiceprinting) has been used to investigate whether the speaker in a tape-recording is the same as a suspect.

       

      語音學和計算語言學對某一言語樣品作聲學分析,以此推斷說話人的身份。說話人驗證是對某一言語樣品作聲學分析,將一設定的身份與計算機內存儲的參照樣品相比較和驗證。說話人認同是將一已知說話人的言語樣品與一未知說話人處獲得的樣品相比較,以決定兩者是否為同一個人。這項技術最常用于犯罪偵破,頻譜的視覺分析(聲紋)可用來調查錄音上的說話人是否就是犯罪嫌疑人。
