I'm Spencir, an experienced 11 year old boy voiceover artist. My voice is perfect for your video, game, or slideshow anytime you need a boy's voice that is neither too babyish nor too grown up -- just right. Here's a sample of a gig I recently did for a client on Fiverr:
I have good voice inflection - and can do fun animated characters or serious narration.
I have upgraded my audio capacity since I did the video sample for my Fiverr page -- I now do all my voiceover work in a completely quiet environment using a Blue Microphones Snowball Professional USB microphone and a MacBookPro. Though I generally provide files in MP3, WAV or AAV, I can probably work with you if you need another format.
I hope I can help you on your project. (Even though my Dad helps me with my projects and communications, I get to keep all the $ I earn on Fiverr. Yay!)
