Voice

Over the years, Simlish speech has been provided by a wide range of different actors, each giving their own style and charm to the Sims they voice.

The Sims
In The Sims, male Adult sims are voiced by Stephen Kearin, while female adult voices are performed by Gerri Lawlor. These two actors are the inventors of the Simlish language. Sean O' Connor, Laurel McCarl Kapros, Paul Rausmussen and Eli Sibley perform additional voices. In The Sims: Makin' Magic, Nikki Rapp makes her debut as the voice of Child sims.

The Sims 2
In The Sims 2 there is a wider range of voice actors, to accomodate the increased number of life stages.
 * Child sims of both genders are once again voiced by Nikki Rapp.
 * Teen males are voiced by Jack Conte, and teen females are voiced by Thessaly Lerner. If The Sims 2: University is installed, they are also the voices of Young Adults.
 * Adults of each gender now have two separate voices, chosen automatically by the game upon the Sim's birth or creation in Create a Sim. The player cannot control which voice the Sim is given. Gerri Lawlor returns, notably voicing Cassandra Goth, Dina Caliente and Kaylynn Langerak. Stephen Kearin also returns, notably voicing Don Lothario, Darren Dreamer and certain NPCs such as Unsavory Charlatan. They are joined by Zoe Galvez, who voices Mary-Sue Pleasant, Nina Caliente and Brandi Broke, and Dave Boat, who voices Daniel Pleasant and NPCs such as the Genie and Bigfoot.
 * Elder voices are performed by Roger Jackson and Liz Mamorsky. Roger Jackson is also the voice of certain NPCs, such as the Therapist and witch doctor.
 * Additional voices, presumably including those of Baby and Toddler Sims, are performed by Donna LeTourneau and Phil Sheridan.

The Sims 3
In The Sims 3, for the first time players are able to choose their Sim's voice, and even alter the pitch. This voice stays consistent throughout the Teen, Young Adult, Adult and Elder life stages. This, however, has the unfortunate side effect of the voice actors having to give much more "flat" performances, to keep the age ambiguous and avoid audio issues with the dynamic pitch.

The player can choose between three different voices in Create a Sim for most life stages, but only two for children. Only two past voice actors return; Nikki Rapp and Donna LeTourneau. New voice actors in The Sims 3 include Khary Payton, Elisa Gabrielli, William Salyers, Georgina Cordova, Will Blagrove, Becky Boxer, William Woff and Deborah Ben-Eliezer.
