Make useful answers easier to listen to
When a good answer appears in Slack, turn it into audio so the team can hear it again without searching the thread.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Text to speech
Converts text to speech using a specified elevenlabs voice and model, returning a downloadable audio file.
Why this helps
Repeated questions take time when a clear answer already exists somewhere in Slack.
- Make a strong answer easy to review by listening.
- Give teammates another way to absorb recurring guidance.
- Reduce time spent locating a useful answer in channel history.
Setup
Build it in a few focused steps.
- 1Connect Slack and ElevenLabs to Notis once through the portal.
- 2Create an automation in Automations or ask Notis conversationally.
- 3Describe which reusable FAQ answers should become spoken audio.
- 4Select Channel Message Received and choose where run reports appear.
- 5Test with one real answer to a recurring question.
Questions about this workflow
Can I limit the workflow to FAQ-style answers?
Yes. Explain what a reusable answer looks like in your prompt.
Will it post the audio in Slack?
The selected ElevenLabs action generates audio. Posting it back would require a separate supported action.
