Voice Expert's Report on the Alleged PGMAs
Ernst F. S. Alexanderson, president of Voice Identification Inc., also said certain recorded segments of the telephone conversations are contiguous, uninterrupted and unaltered and appear to be legitimate reproductions of the original telephone calls.
Alexandersons findings are contained in two letters dated last June 3 and 9 and addressed to lawyer Felix Carao of the Saguisag Carao Law Office.
The American voice expert said he needed to do more comparisons to find enough evidence to be convincing and conclusive. But Tatad said a Filipino voice expert told his group that Alexandersons findings are sufficient to conclude that the voices in the recordings are those of the President and Garcillano.
On Mrs. Arroyo, Alexanderson said in his June 3 letter, An aural comparison to the cassette recording of Macapagal-Arroyo indicated a strong similarity in the sounds of the voices, suggesting it was the same speaker.
On Garcillano, he said in his June 9 communication, Our aural comparison indicated a similarity in the voices. Of particular interest to us was the s sounds, in which both known and unknown Gary spoke with a lisp (a speech impediment).
Alexanderson, a certified voiceprint examiner, is said to have analyzed about 250 cases involving voiceprint comparison and trained about 100 law enforcement personnel in voice identification. He is also said to have taken part in research studies involving aspects of identification such as limited frequency response, disguised voices, electronically altered voices, mimics and family members.
As a voice identification expert, Alexanderson is regularly tapped as a court witness in the District of Columbia. He is listed in expertpages.com, the leading Internet directory on expert witnesses and consultants. His company, Voice Identification Inc., produces sound spectographs for use in forensic voice identification and for use in the speech field.
