Does the following text say that the soundtrack consists of three voices: 1. an authoritative voice, 2. a child’s voice, and 3. Hiller’s own voice?
Context:
Over the flame images, a soundtrack consisting of an authoritative voice interspersed with a child’s (Hiller’s son) recounting of a memory of seeing Rembrandt’s Belshazzar’s Feast, is combined with whispering, improvisational nonsense in Hiller’s own voice to invoke different mnemic registers that explore the interchange between image and word.
