LADY JUSTICE CARR:
Introduction
The facts
Grounds of appeal
"1. As your counsel accepts the Judge gave all appropriate directions to the jury. Identification by voice is permitted. It is not suggested that the Judge should have stopped the case at the conclusion of the prosecution evidence. The jury heard the evidence and in those circumstances it was for them to reach the appropriate verdict.
2. There was evidence before the jury from the complainant which was capable of supporting his identification of your voice. If the jury accepted that you had threatened him because he thought you had had a relationship with your wife, then that was some supporting evidence.
3. It is not arguable that the conviction is unsafe. Juries make decisions in criminal trials having heard all the evidence and received appropriate directions from the Judge. That is what happened in this case."
Discussion and analysis
Identification of a suspect by voice recognition is more difficult than visual identification;
Identification by voice recognition is likely to be more reliable when carried out by experts rather than lay listener identification. An expert is able to draw up an overall profile of the individual's speech patterns. The lay listener's response if "fundamentally opaque";
The ability of a lay listener correctly to identify voices was subject to a number of variables, including the quality of the recording (if any) of the disputed voice or voices, the gap in time between the listener hearing the known voice and his attempt to recognise, the ability of the individual lay witness listener to identify voices in general, the nature and duration of the speech which is sought to be identified;
The greater the familiarity of the listener with a known voice the better his or her chance of accurately identifying the disputed voice.
