Assigning a voice to an agent

curl -X PATCH https://voxbridge.cc/dashboard/agents/AGENT_UUID \
-H "Authorization: Bearer YOUR_JWT" \
-H "Content-Type: application/json" \
-d '{"voice_id":"english_uk"}'
Invalid voice_id values return 422 validation errors. New agents default to default unless specified at creation.

-H "Authorization: Bearer YOUR_JWT"

Design guidance
- Match voice tone to call intent — authoritative voices reduce rapport on welcome calls.
- Use regional accents when callers expect UK, Indian, or Caribbean English — not only script wording.
- Pair voice choice with system prompt tone; a calm prompt with an authoritative voice sounds inconsistent.
