Listen to the Slack updates that matter
Make a useful audio recap from a Slack update, so the next important detail does not disappear in a crowded channel.
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
Scanning a fast-moving channel can make it easy to miss the one update that needs attention.
- Review a selected channel update by listening instead of rereading.
- Keep an important detail accessible while you are away from Slack.
- Reduce the effort of switching back into a busy conversation.
Setup
Build it in a few focused steps.
- 1Connect Slack and ElevenLabs to Notis once through the portal.
- 2Open Automations and create an automation, or ask Notis to create one in plain language.
- 3Tell Notis to turn a priority Slack channel message into a spoken audio clip with ElevenLabs.
- 4Choose the Slack Channel Message Received trigger and a channel for run reports.
- 5Test it by posting one real update that should become audio.
Questions about this workflow
Will every channel message become audio?
Describe the messages you want in the automation prompt. Notis uses your instruction to decide which received messages fit the outcome.
Do I need to configure audio fields?
No. Describe the spoken result in plain language; Notis interprets the request.
