Critical scientific analysis of other labor done on sound or speech evidence. The Speech Science laboratory services we present include. The Forensic Safe Laboratory provides court services to back up both the speech sound processing services and Speech Science services we offer. The court services we provide include. Currently speech evidence is dealt with in our courts in the realm of opinion with the defense and prosecution sometimes having differing opinions. This suggests that currently the chain of evidence concept does not apply to speech evidence. We at The ASL recommend that speech evidence is handled in the alike way as medical evidence. Needs to be dealt with in court as expert opinion and not opinion. Needs to have set procedures in acquisition, processing and preparation that ensure the integrity of evidence is maintained. Needs to be dealt with lower consultation of technical and humanities speech experts. The legal concept of plausible dispute suggests that a scientific or statistical framework needs to be applied to the process of dealing with speech evidence for that chain of evidence to be maintained. This is needed whether obtaining a transcript, enhancing speech, speaker identification and media authentication.
