# Speech Engine: Cascade timeout: Speech Engine create and update requests now accept…

By Steven Van · 2026-09-21

A new cascade\_timeout\_seconds parameter (2 to 15, default 4) controls upstream retry timing for Speech Engine requests.

Speech Engine create and update requests now accept a **cascade\_timeout\_seconds** parameter, a number between 2 and 15 that sets how long [ElevenLabs](<https://creatorstoolbox.com/tools/elevenlabs>) waits for an upstream speech engine before retrying, with a default of 4. Create requests default to this value, update requests accept a nullable value, and responses now require the field.
