Since 2007, Devall produced his own podcast, Voiceprint with Trevor Devall & Guests, where he interviewed fellow Vancouver-based voice actors and answered questions from fans. Each episode featured a different voice actor as the episode guest, though some episodes featured other people in the voice-acting business that may not actually be voice actors themselves; or behind-the-scenes looks at the life of a voice actor. Topics usually included how the guest made it into the voice-acting business, what it is like working in the industry, and the general lifestyle of a voice actor. The series concluded its first season after 36 episodes in December 2013. The second season was announced in the final episode of season 1, as Trevor moves to Los Angeles, California to continue his career and the show.
Season finale; In a reversal of roles, Devall was interviewed by series premiere guest Sam Vincent.
