List → Design a Voice
AI-generatedSummary
Designs a HeyGen voice by sending a natural-language prompt to the v3 voices API. An optional seed is included when it contains a numeric value, to request another batch of suggestions.
Inputs
- Authentication — Choose OAuth2 (the default) or the legacy API key method to authenticate with HeyGen.
- Prompt (required) — Natural-language description of the voice to design. The operation trims whitespace and errors if the prompt is blank.
- Seed — Optional numeric seed; when provided as a number, it is sent with the prompt. Non-numeric values are omitted.
Output shape
A single item containing the HeyGen API response.
The operation sends POST /v3/voices. The response is returned as received; its fields depend on HeyGen's API response. With Continue On Fail enabled, errors are returned in an item as {"error":"…"}.
