If you're putting together your eLearning or online training content and you can't stand the sound of your own voice, or you just need a professional voice of a different accent or language to narrate the audio, look no further than www.voice123.com. Voice123 is a really cool site that has hundreds of thousands (!) of voice producers and voiceover professionals waiting to audition for the part.
How it works is that you either search the database for that perfect voice or post your requirements up on the site. If you choose to 'Post a project' you'll need to outline some criteria (female, middle age, British etc) and put your custom script up for different voiceover people to audition. They say you'll start receiving auditions within an hour and you can also invite talent you like to submit their audition.
One of the coolest things is that the casting part is free. It's essentially up to the voiceover professional to audition, then you can assess their proposals which means you can always make sure to stay within your budget.
I listened to quite a few of the voice professionals and recognized a number of the voices from various TV commercials, radio advertisements and airline videos. It's amazing what a good voiceover can do for an otherwise dull training topic!
