 note = {音響法科学はメディア法科学の一分野であり，音響学の原理と技術を犯罪捜査・法廷のために活かす研究と学問を指す．音響法科学の話題は，音声科学研究の一分野でもある話者識別，音響信号処理研究の一分野でもある雑音除去と音声強調，そして録音属性推定の三つに大別される．本講演では，前二者を概説したのち，録音属性推定に含まれる，録音対象識別，録音改ざん検出，録音機器および録音環境の推定，音響信号への情報秘匿の有無検出 (ステガナリシス) について触れる．特に，講演者が取り組んだ後二者の研究，録音機器および録音環境の推定とステガナリシスについて，少し詳しく解説する．, Audio forensics is a research field of media forensics for criminal investigations and courts by utilizing acoustical science and technology. Research topics on audio forensics include speaker identification, a field of speech sciences, noise reduction and speech enhancement, a field of audio signal processing, and estimation of recording properties. This invited talk briefly introduces the former two topics, then moves on to the latter, which consists of recording target identification, tamper detection, estimation of recording environments and recording devices, and audio steganography. Mainly, the latter two topics, recording environment and device estimation, and audio steganography, tackled by the presenter, are described in more detail.},
