Voice Testing Specifications

Netflix requires dubbing studios to use voice talent that has been established as the in-territory counterpart for any actor involved in the original production. If that voice talent is unavailable for any reason and timelines cannot be shifted to accommodate or if the original production actors do not have established talent, Netflix may wish to approve casting choices via voice samples or voice test kits.

Voice Samples

Please provide audio file samples, each containing a different actor’s performance, for each role being cast. It is preferred to include samples from talent who has voiced the original actor in the past (and a clip from that performance) and/or samples of a performance that resembles the one being cast.

These files should adhere to the following:

  • The dominant speaking role in the clip should be that of the actor being considered, preferably as “dry” audio with no other music or effects.
  • File should preferably be a minimum of 45 seconds and a maximum of 60 seconds in length.
  • When available, please include file with actor reading his/her name in normal speaking voice as part of or in addition to performance sample.
  • Please name file as [NameOfRole]_[ActorName].
    • Optional: File name can contain numerical designation after the name of the role to denote director’s preference with 1 being the top choice.

Line Voice Tests

For higher touch projects, Netflix will approve roles based on a test performance of the role for which the talent is being considered. Netflix will provide the studio with a clip from the original production and will request audio files containing the dubbing performances of the voice talent being considered. Netflix accepts .wav and muxed .mov files. Please contact the specialist to see what is preferred.

The files should adhere to the following:

  • The sample performance should have the same runtime and be in sync with the clip provided.
  • Before test performance, actor should read his/her name in normal speaking voice (preferably over slate).
  • Please only dub dialogue for role(s) being cast and do not include any other production audio in the clip. If an M&E mix and/or stems are available, it is okay to use these in the mix of the voice test.
  • Each file should contain one performance/test only and be named as [NameOfRole]_[ActorName].
    • Optional: File name can contain numerical designation after the name of the role to denote director’s preference with 1 being the top choice.
