As with any task involving statistical pattern recognition, the assessment of
spoofing and anti-spoong approaches for voice recognition calls for signicantscale
databases of spoofed speech signals. Depending on the application, these signals should normally reflect spoong attacks performed prior to acquisition at the sensor or microphone. Since the collection of large quantities of any biometric data is always extremely time consuming and cost prohibitive, and consistent with some telephony applications, almost all of the existing work to assess spoofing and anti-spoong in voice recognition is performed with databases of speech signals subjected to post-sensor spoong attacks. While such a setup can be justied, the lack of suitable sensor-level databases is a weakness in the research eld. Additionally, whereas spoong relates to authentication, and thus predominantly text-dependent scenarios, the majority of the related work involves
the use of text-independent databases better suited to surveillance applications than to authentication and spoong.
