* In the beginning of ''Machinima/RedVsBlue'' Caboose sounds completely different than how he does now. At first he sounds normal, but due to {{Flanderization}} he has gotten more idiotic sounding, with his speech pattern now halting and slow along with being more prone to random fits of SuddenlyShouting. It has happened to nearly every character to a minor extent, but Caboose is so different, it's almost disorienting when rewatching the earlier seasons.[[note]] Caboose's idiocy is explained that his mind was broken beyond repair when the evil AI controlling him at the time was ripped from his head. In addition to this, [=DVD=] extras suggest, if not state outright, that, when Caboose's mental image of Church was killed, he lost all the knowledge he'd ever been taught by Church.... which the extras go on to say was quite a lot, apparently.[[/note]]

* ''WesternAnimation/ToyStory4'' sees the return of Bo Peep after her absence in [[WesternAnimation/ToyStory3 the previous film]], with Annie Potts reprising her role from the [[WesternAnimation/ToyStory first]] [[WesternAnimation/ToyStory2 two]] films, but her voice is noticeably lower in pitch, likely due to age.

*** Matt Vogel, his understudy and eventual successor, also falls under this. At first, he sounded much like Caroll Spinney when he finally made him more innocent and naive. When he took over the role full time in 2015, while still sounding like a child, made him sound a lot older.

** Big Bird is this in more ways than one. Caroll Spinney initially gave him a deep, hick-like voice due to him being rather dumb. Once the character was retooled to be more innocent and naive, he gave him a much higher voice. During the later years of his life, when he was in his ''''80s''', he became slower and more nasally.

* ''Radio/AmericanTop40'': Compare the Casey Kasem of 1970 (the show's earliest days) to his retirement from radio in 2009. His delivery was much different during the early shows (1970-early 1972), before changing into the form that fans know him best for (c. 1973-the late 1990s). By the early 2000s, age began taking its toll, and although he was definitely still Casey, his voice had grown much weaker. Despite the changes in his voice, Casey was still sharp as ever and -- approaching his late 70s by the time of his retirement, was still able to show enthusiasm and sell the music that listeners more than 50 (and sometimes 60) years his junior were avidly listening to.

** Creator/JamesEarlJones' voice for Darth Vader in ''Film/ANewHope'' was a bit higher-pitched and more emotive, before becoming deeper and monotonous in ''Film/TheEmpireStrikesBack''. His Vader voice in ''Return Of The Jedi'' seemed to be a mix of the two. ''Film/RogueOne'' has an unavoidable case, as Jones' voice had changed with age and Vader sounds a bit deeper and speaks a bit more slowly. In ''Series/ObiWanKenobi'', Vader is back to sounding like he did in ''Empire'' and ''Jedi'' due to the use of the Respeecher software to recreate Jones'classic Vader voice (the same method was used to recreate young Luke Skywalker's voice in ''Series/TheMandalorian'' and ''Series/TheBookOfBobaFett'').

In ''Series/ObiWanKenobi'', Vader is back to sounding like he did in ''Empire'' and ''Jedi'' due to Jones' classic voice being synthesized through Respeecher.

** General Grievous' voice in ''Revenge of the Sith'' was slightly different to how he would sound in ''The Clone Wars'' and subsequent projects, being more heavily synthesized and sporting a thick Eastern-European accent, both of which were toned down in ''The Clone Wars''.

* Cecil, TheNarrator of ''Podcast/WelcomeToNightVale'', is always NPR smooth and sonorous, but as his character develops throughout the series he becomes more emotionally dynamic. This is especially obvious in the first anniversary episode "One Year Later", which begins with an IronicEcho of the intro from the pilot. The words are almost identical but the reading has changed drastically.

** Same goes for Mickey Rourke, although it's been overshadowed by the change in his physical appearance.

** Carrie Fisher's voice is noticeably huskier in ''Film/ReturnOfTheJedi'' than it is in the previous two movies.

** Anthony Daniels' voice for C-3PO got a bit higher pitched following ''A New Hope''. It is worth noting he spoke his lines in ''A New Hope'' believing he would later be dubbed over by another actor.

* Creator/SeanConnery[='=]s deep voice got raspier and his lisp and Scottish accent got thicker over the years after he did his last official ''Film/JamesBond'' [[Film/DiamondsAreForever movie]] in 1971.
* Marlon Brando's voice as Vito Corleone in ''Film/TheGodfather'' becomes raspier in the later scenes when Vito is older and more frail.

* Eva Green naturally started out with a very thick [[https://www.youtube.com/watch?v=vRsWz4oNvf8 French accent]] but years of working outside French cinema has left her sounding [[https://www.youtube.com/watch?v=cgNLNE_rF6I slightly British]]. Her voice in ''Film/KingdomOfHeaven'' is in-between - where her voice just sounds ambiguously exotic.

* Creator/JeanneMoreau's voice got [[VocalEvolution increasingly smoky and gravelly]] due to chronic laryngitis, which was related to her smoking habit.

** When Kermit the Frog was in the first 20 years of his career (1955-1975), his voice sounded deeper, softer, quieter and somewhat stuffy and dull. Beginning in 1976, his voice became louder, more rubbery and less stuffy.

* Jaleel White, who played the role of Sonic in [[WesternAnimation/SonicTheHedgehogSatAM three]] [[WesternAnimation/AdventuresOfSonicTheHedgehog animated]] [[WesternAnimation/SonicUnderground shows]], reprises his role in the ''WebVideo/{{Sonic}}'' fanfilm, with his voice sounding somewhat more like the modern incarnations.

* Wrestling/ScottHall originally used the Cuban accent he used for Razor Ramon when first debuting as an "Outsider" on WCW. He eventually phased it out altogether (due to having little choice since WWF still owned rights to Razor Ramon).

* WebVideo/TheAngryVideoGameNerd's actual voice has stayed pretty consistent throughout the series' run, but you can definitely hear a gradual improvement in his public speaking skills over the years. Strangely, in 2011, he spoke in a much lower and mellower tone than usual, which made him sound more ''irritated'' than angry (WordOfGod suggests that this is because his heart was not really into making AVGN videos at the time, because he wanted to begin work on the AVGN movie). Fortunately, in 2012, he returned to his normal pitch/aggression and now sounds pretty much the same as he did before (except more relaxed and confident).

* Jeff Sweeney, the Creator/TreehouseTv male announcer, has also went through a vocal evolution: His voice first started out high-pitched and youthful, but as years went on, his voice became slightly deeper and more masculine due to him aging.

* The male announcer for the Canadian preschool channel Creator/TreehouseTV has also went through a vocal evolution: His voice first started out high-pitched and youthful, but as years went on, his voice became slightly deeper and more masculine due to him aging.
