Okay, it definitely took longer to complete this as expected (doesn’t it always?), but we finally got the professional voice over done for our training videos and you can hear the result here:

We had to restart the voice over project twice and change actors/platforms as we weren’t happy with the initial results.
In general we found that VoiceBunny didn’t work well for us for longer projects (the training videos have a combined word count of ~10k). The problem is that the platform doesn’t provide any ways to exchange feedback between actors and clients once you’ve selected an actor for a project.
VoiceBunny’s workflow expects the voice actor to complete the full project first before clients can provide any feedback, which is ridiculous if the project takes a full day in the studio to complete. It would make much more sense if clients could provide feedback after some initial recordings to e.g. get the tone or pronunciation of certain parts right.
We also found that there were quite a few unprofessional actors on the platform who cannot get the basic audio quality right (e.g. multiple recordings sound completely different).
In the end we tried voices.com and it worked much better for us. The experience was much more professional and we also found the voice over actors to be better on average (based on the audition submissions we’ve received). With the final voice over actor we were able to complete the project within a couple of days with just a few rounds of smaller revisions.
