work on speaker identification cannot be done until the recording is of proper quality. Different solutions for poor comprehensibility are done using computer programs that allow the user to filter and eliminate noise. Computer software is also able to convert the speech to spectra and waveforms, which is useful for the forensic phonetician. However, any work done on the recording should be done after a copy of the original recording is made. A main part of the forensic phonetician's job is speaker identification. The interpretation process might include piecing together a timeline, transcribing the dialog, and identifying unknown or unintelligible sounds in the audio recording. In court, the expert ultimately serves to explain the facts surrounding the audio evidence, providing an explanation of relevant acoustical and physical principles to explain what is evidenced by the recording. Reports are made to include detailed information, if there is a section of the recording that is not comprehensible or is inaudible, an explanation of what was happening (in the recording), and a description of what is missing from the recording. Speaker Identification Voice analysis has a role in speaker identification. This is when the identity of a speaker is unknown, and has to be identify from an array of other voices or suspects when pertaining to a crime investigation or court trial. Proper identification of speaker and voices particularly for criminal cases depend on a list of factors, like familiarity, exposure, delay, tone of voice, voice disguising, and accents. Familiarity with a speaker increases the chances of properly identifying a voice, and distinguishing it. The amount of exposure to a voice also aids in correctly identifying a voice, even if it is an unfamiliar one. A hearer that listen to a longer utterance or was exposed to a voice more often is better at recognizing a voice, than someone who perhaps was only able to hear one word. A delay between the time of hearing a voice and the time of identifying the speaker also decreases the prospect of identifying the correct speaker. The tone of voice affects the ability to identify the right speaker. If the tone does not match that of the speaker at the time of comparison, it will prove to be more difficult to analyse. Disguise of the voice, for example when a speaker is whispering, will also hinder the ability to accurately match and identify the speaker. In
