I have probably had over 100 roles online for non-profit projects from sites such as newgrounds, Voiceactingallience and of course youtube.
I have had my voice in a few video games, machinima, an amateur film and even some songs.
Most of my work is for over-overs and character style voices. Though I know I can easily sound like a reporter or instructor depending on the job description.
I took acting classes for a year which really helped me open up and not be afraid to try new things.
I also read plenty of blogs from professional voice actors and watched videos about voice acting to learn what I could do differently.
I have a small second of my room reserved for recording. I make sure it is quiet and sound and that there isn't anything disturbing around to change the quality of my recording.
I use a samson q2u microphone and record and either audacity or mixcraft 5.
I am very reliant and have gotten several great messages from people who have worked with me and enjoy my work. I try to be quick to reply to all messages and am OCD about organization and being on time.
