Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Text to speech

Why this helps
A brand name or founder's name can be spoken inconsistently across generated audio.
- Record pronunciation corrections where teammates already discuss them.
- Reduce repeated manual fixes for familiar product terms.
- Improve consistency in future speech synthesis.
Setup
Build it in a few focused steps.
- 1Connect Slack and ElevenLabs to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to create it conversationally.
- 3Instruct Notis to add the term and pronunciation from a marked Slack message to the appropriate existing dictionary.
- 4Choose Message Reaction Added and select a run-report channel.
- 5Test by reacting to one real pronunciation note; confirm an existing dictionary is available.
Questions about this workflow
Does this create a pronunciation dictionary?
No. It adds rules to an existing pronunciation dictionary. Make sure the relevant dictionary already exists in ElevenLabs.
What should the Slack message contain?
Include the term and how it should be pronounced, then use the reaction you chose for this workflow.
