Forensic Voice
Professions like Phonetics, Speech-language pathology, voice teachers and musicians deal with different aspects of voice. Forensic voice analyses voice, by examining transmitted and stored speech, enhancing it and decoding it for criminal investigations, court trials, and federal agencies. The first part is to make the speech in a recording comprehensible, since in different cases recording or samples can come from surveillance, phone calls, ‘bugs’,etc;technology that do not have the best sound quality. This is done by filtering any noise that interferes with the speech or the speaker. These disruptions can come from the environment, noises such as the wind, and any other rustling, disruption may come from another speaker or other voices, any sudden sound like a car horn, or it can come from the equipment/technology that is being used to record. The adjustments are done in a digital copy, as to not alter the original recording. Spectrogram, or waveform are useful to visualize areas of concern. The second part involves speech decoding where a background in language is necessary, like that of a phonetician. Anyone working with voice, will be able to analyse the characteristics of a voice, for example accents and dialects, any voice disguise, stress in speech, tones of voice, multiple speakers, and voice affected by intoxication, fatigue, and bad health. Reports are made to include detailed information, if there is a section of the recording that is not comprehensible or inaudible an explanation of what was happening (in the recording) and what is missing needs to be included.

Speaker Identification
Voice analysis places a role in speaker identification, 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 chance of properly identifying a voice, and distinguishing it. The exposure to a voice also aids in correctly identifying a voice, even if its 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 some cases, Individuals who speak the same language as the speaker whose voice is being analysed will have an easier time identifying them because of the accent and stress of a voice.


 * Voice analysis as evidence

Look more into the linguistic challenges, or linguistic methods of voice analyzing. When is voice analyzing in forensics appropriate. Explain or expand on how voice analysis are used as evidence. In addition, discuss what is considered a useful, or good source for voice analysis and what is not. Linguistic approach to analyzing voices, and their explanations of the evidence to others who may not be well verse in linguistic topics.


 * Voice analysis, and how they stand in the justice system and courts

How credible are they considered to be? Do they have the power to persuade the jury more than any other evidence. Do lawyers find them to be useful, and do they use these kinds of evidence appropriately, whatever that may mean.

Taylin's Ideas
This article is fairly new and does not have many resources to back up its information. The article's talk page states that the article is part of the wiki project on mass surveillance. The article itself does not mention how voice analysis can be used as a mean of mass surveillance or how it is related to this topic. More topics on the page regarding voice analysis and its benefits would be helpful to readers. This article uses a lot of technical language and is not very easy for someone who is not familiar with this topic to understand. I think it would be beneficial to the page for it to be broken into easier language and for more subtopics to be introduced.

24.45.167.146 (talk) 02:53, 8 April 2019 (UTC) The paragraph I want to edit is the first paragraph of the article; "Typical Voice Problems". The paragraph is slightly confusing because the content of the paragraph does not necessarily match the header of what it is going to be about. There is some good foundation but it does not completely get to the point. I want to edit this paragraph so that it is more informative of what different types of voice problems exist so that others are able to realize the medical benefits voice analysis may have. Two of the disorders I want to include in the revision are dysphonia and aphonia as these are disorders that affect the acoustics of the voice directly. Here are some informative websites I'm planning to use in order to make these edits.

Taylin's Second Edits
I am going to edit this section to make it easier to read. I do not think the wording makes the most sense for what it is trying to say. Original: A medical study of the voice can be, for instance, analysis of the voice of patients who have had a polyp removed from their vocal cords through an operation. Objective evaluation of voice quality improvement requires some way to measure of voice quality. An experienced voice therapist can quite reliably evaluate the voice, but this requires extensive training and is still subjective.

Edited: Medical studies of the voice can be used to analyze many patients. Voice quality improvement evaluations are effective voice analysis tests that can help track if a person's voice quality has improved or decreased. This type of test can be used, for example, on the voice of patients who have had a polyp removed from their vocal cords. This type of operation can effect the patient's voice quality. Through voice therapy and lots of training a patient's voice quality can be restored and quality can be effectively tracked through voice analysis.
