Speaker Identification &
Audio Forensics

Disputed telephone recordings, extortion call notes, wiretaps, and tampered audio evidence require scientific spectrographic analysis to verify speaker identity and detect digital manipulations. At Skyline Centre of Excellence, we provide forensic Speaker Identification and Audio Examination Services using advanced acoustic spectrographic analysis, formant frequency profiling (F0, F1-F4), AI deepfake voice clone detection, adaptive audio enhancement, and Section 45 expert testimony.
