Description

  • The Live Call Control say section in fern/calls/call-features.mdx shows only content and endCallAfterSpoken.
  • Documents interruptionsEnabled and interruptAssistantEnabled (both default false).
  • Documents audio playback: when the entire content is an https:// URL, the audio at that URL is played instead of synthesized. Anything else, including http:// or a URL inside a sentence, is spoken as text.

Evidence

  • live API spec (https://api.vapi.ai/api-json, 2026-10-14): ClientInboundMessageSay has content, endCallAfterSpoken, interruptionsEnabled and interruptAssistantEnabled ("@default false").
  • interruptionsEnabled default and the https-only, whole-value URL rule: verified against the current API implementation.

Testing Steps

  • fern check (pinned 5.151.1) passes locally
  • Check the preview deployment for the changed page

The say control message accepts interruptionsEnabled and
interruptAssistantEnabled (both default false), and plays content as
audio when the whole value is an https URL.
