The latest official developer blog on the Star Wars: The Old Republic site gives fans more information about the voice over work for an epic sized MMO. Read a bit below:

Here are some other tidbits about the VO on The Old Republic:

• The voice-over is being recorded in 5 different cities (so far); Los Angeles , London, New York, San Francisco, and Toronto
• By the time the project is finished, we will have worked with hundreds of actors - many on multiple occasions.
• The entire game 'script' contains approximately 40+ novels worth of content.
• One of the biggest challenges of the production: consistency in pronunciation across the whole project! You would be amazed at how many ways there are to say "Thul" or "Holo" Projector. An audio pronunciation guide sure has helped :).
