Handling AI-Generated Content

About Nextory's Stance on AI

As a distribution channel, Nextory does not control the content of the books; the responsibility for the work's design lies entirely with the respective publisher. We see that more and more partners are exploring AI for, for example, synthetic voices or AI-generated illustrations. To ensure transparency towards the end customer together, Nextory requires that all AI content be strictly declared in the metadata according to industry standards.

AI Narrators (ONIX List 19)

AI and synthesized narrators should be sent using the UnnamedPersons ONIX field, with ContributorRole set to E07 (narrator).

Examples

Example 1 — Code 08, named voice basis:

Synthesized voices that are sampled based on real voice actors can be specified using AlternativeName. Only the voice actor's name is relevant for this field — it should not be used to specify narration models.

{
  "ContributorRole": "E07",
  "UnnamedPersons": "08",
  "AlternativeName": {
    "NameType": "04",
    "PersonName": "Anna Larsson"
  }
}

Display output: Anna Larsson(Synthesized voice)

Example 2 — Code 06, unnamed female voice:

{
  "ContributorRole": "E07",
  "UnnamedPersons": "06"
}

Display output: Female (Synthesized voice)

Nextory is not interested in the specific AI model used — model names cannot be added as part of AlternativeName.

⚠️ AI-narrated content without clear declaration in the metadata may be deactivated by Nextory administrators.
