- The recording of the voiceover should be in WAV format, which provides the best audio quality
- The recording should take place in a recording studio or in a controlled environment that is acoustically desirable and isolated to reduce background noise.
- The microphone should be a high-sensitivity digital microphone, preferably unidirectional
- Closed or semi-open headphones
- Microphone stand: this makes the work easier and helps avoid vibrations

- Video editing
- The video has a voice-over, which can be turned on and off.
- The voice will accompany the sign language, not the text.
- The duration of each film block is calculated and then used to time the voice recording, which should last about the same as the sign language block.
- In the case of literary texts, the voice-over will accompany the written text.
- In the case of storytelling, a voice-over accompanies the narrator.
- The team will convene persons to put their voices to the text or story.
- A detailed timeline will be developed by the reader and the sound engineer.
- Each reader will practice reading according to the speed of the sign language narration.
- The reader must agree to the use of his or her voice.
- During the recording, an assistant will make sure that the reading of the text, the pronunciation, intonation, and timing are adequate.
- The sound engineer edits the voices and sends the files to the coordinator, who checks them before sending them to the editor
