SPEECH
Speech is a big part of the audio in today's games. In the beginning, games could get away with bad voice acting because any voice acting was considered cutting edge, and because it was too new to be an integral part of the player's gaming experience. However, those days are now gone, and today, having bad voice acting is no better an option than having no voice acting.This section will take a look at some ways to get high-quality speech integrated into your game.
Hiring Voice Actors and Actresses
There are many professional, as well as aspiring, voice actors and actresses out there ready and willing to provide voices for your game's characters. Usually these talents are relatively affordable—a few hundred dollars—though, like everything else, you can pay a lot of money for a highprofile actor or actress.Working with voice actors and actresses is technically very easy, because virtually all of them have their own professional recording studios and enough technical know-how to send sound files back and forth through e-mail. Most of the time, you just send your actor or actress a script containing the exact lines you'd like him or her to say. Explaining the emotional state of the character at that point can also help (if it isn't obvious just by reading the script).If you don't want to pay for contracting voice actors or actresses, consider enlisting the help of a few friends. Talk to some people you know, give them their scripts, set up your recording equipment, and invite everyone over to speak their lines, hang out, have dinner, or whatever. Many people really enjoy voice acting, especially when they know that their likeness isn't going to go along with their voice. Also, try it yourself! Once you get past the weirdness of hearing your own voice recorded, it's actually quite fun to vocalize a range of expressions and try to add life to your characters.
Localization Issues
One of the most difficult things to deal with when it comes to in-game speech is the issue of localization. If you want your game to be easily accessible to non-English speaking players, you will need to deal with the issue of localization.Localization can quickly increase the number of lines for your voice actors. It may also require that you hire voice actors that can speak different languages.Think carefully up-front about what languages your game will be in, and whether those languages will have their own set of voice files. If dialog isn't that critical to the gameplay in your game, you might be able to keep English voice files coming out the speakers, but have text captions in the correct language displayed on screen.
Lip-Syncing
One of the most difficult aspects of in-game speech is syncing the motion of the game characters' mouths to the audio that's coming out of the speakers. Even today, most games don't do this well enough for their players to actually believe that the characters are talking. However, technology is progressing, and there are already some programs on the market specifically designed to deal with the problem of lip-syncing audio to characters in games or computer renderings.To properly lip-sync, you need to break down your source sound into distinct phonemes. Phonemes are to speech what bits are to data; in other words, phonemes are the atomic units from which all speech is created. Each phoneme can be mapped to a specific shape of a character's mouth, allowing you to easily animate the character once you have broken down the source audio file into a set of phonemes. There are programs that help you do this; I've included links to some of them on your CD.
