Voice Synthesizer

A Voice Synthesizer (VS for Short) is a small device seen in the Sapphire Foxx Universe that allows the user to alter the sound and pitch of their voice. A VS is often shown to take the form of a choker styled neckband with either a rounded red or a grey decorative diamond shaped charm on the front. When worn by an individual it allows them to change the tone of their voice for various reasons. Mostly for the purpose of sounding more like the opposite gender when the individual in question is unable to change their tone of voice on their own effort. A VS offers multiple settings. It can use a base sample of a certain persons voice and copy their tone and pitch to give the user the sample individual's voice or it can quickly analyze the users own voice and alter it to sound like the opposite gender thus making a female voice sound more masculine and a male voice sound more feminine. It can also simply distort a voice to make it unnoticeable over audio calls and such to help an individual hide their own identity. While the broach or charm on the front seems to house the main component of the device that effects the user's voice the back of the band where the clasp is hidden seems to house the switch that changes the settings of the device to the user's desire. 
== History ==
==== An Untrusting Fiancé ====
The VS was first introduced in the Animation series An Untrusting Fiancé where it is used by Kelvin to both assume the identity of his fiancé's friend Valery and also alter his/her own voice to become her female persona Kelly. Another VS is used by Cyrus to alter their voice between various pitches so they can live their gender fluid life style. With their natural voice being somewhat sultry but Gender Neutral Cyrus uses their VS to gain a more masculine tone when presenting as a muscular man and more feminine pitch when presenting as a woman. At first Kelvin uses his VS to get a voice sample from the real Valery's voice mail so he can disguise himself as her and attend his Fiancé's bachelorette party. Later however his curiosity and sense of self discovery get the better of him and he uses it to alter his own voice and become his female self, Kelly. Later Cyrus is seen using one to alter his more neutral toned voice to better match his Manly muscular body that he is presenting as that weekend. Both Cyrus and Kelly continue to use their VS throughout the weekend and beyond to have some fun and eventually Kelly begins using hers almost constantly after she feels she truly does identify as a woman. Cyrus is later seen using theirs to alter their natural voice into a female pitch to allow her to assume her female persona after spending the weekend as a guy.
==== Favors and Followers ====
A few VS's are seen used by a few characters in the comic series Favors and Followers. Mostly by Lara Jenson to assume her female persona online and out in public as she is unable to alter her natural voice from being Luke through natural means. Lara also discovers that her friend turned enemy Karl Bevil also uses a VS to alter his voice as part of his online presence as Cypher, a cyber stalker who gets off by finding and blackmailing transwomen online in exchange for sexual favors. Though as both of these character have only ever been seen in comic form the actual tone and pitch difference they use is not actually heard. 
== Trivia ==
* Before the introduction of the VS in the SF universe most character's either relied on magic or various vocal exercises to alter their voice between genders.
* An earlier version of the VS (possibly its precursor) has been shown in the form of Ghost Skin masks seen in "Cheater's Punishment" where it is used to alter the wearers voice based on who the mask and suite were modeled after.
* There are several times where a character using a VS is shown still speaking in their altered voice without the VS visible but this is usually a minor animation error.
