Stream speech from a WhatsApp text request
Turn text supplied by a 2chat workflow into an ElevenLabs speech stream when a quick spoken response is more useful than a saved audio file.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Text to speech stream
Converts text into speech and returns an audio file.
Why this helps
A separate audio generation step can interrupt a fast response workflow.
- Create speech output for a responsive voice workflow.
- Keep the text request and speech generation in one automated path.
- Specify text and any supported output preferences in the instruction.
Setup
Build it in a few focused steps.
- 1Connect 2chat and ElevenLabs once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis from any channel.
- 3In one instruction, say to stream the text supplied with each webhook request as ElevenLabs speech.
- 4Choose the webhook trigger and select where run reports should go.
- 5Test with one real request using a short text sample.
Questions about this workflow
Is this a WhatsApp voice note trigger?
No. 2chat exposes no trigger events here. A webhook request starts the automation, and its payload needs to include the text to speak.
When is streaming useful?
Use it when your workflow needs a spoken stream with latency or output-format options, rather than a downloadable audio file.
Are there text length constraints?
The event guidance recommends keeping text preferably under 5,000 characters and notes that output formats can depend on the account tier.
