Snippet: Voicemail Transcription
This snippet will show you how to implement a transcription process for a recorded voicemail message. The resulting text will be emailed to the given address.
You will need a machine with Python installed, the SignalWire SDK, a provisioned SignalWire phone number, and optionally Docker if you decide to run it in a container.
For this demo we will be using Python, but more languages may become available.
- SignalWire SDK
- SignalWire Phone Number
- MailGun Account (For administrator notifications, https://www.mailgun.com/)
- Docker (Optional)
How this Voicemail Transcription application works
We are going to build off of our Simple IVR Menu, and add ring groups

Build and Run on Docker
Let's get started!
- Use our pre-built image from Docker Hub:
For Python: docker pull signalwire/snippets-voicemail-transcription:latest
- Or build your own image:
docker build -t snippets-voicemail-transcription .
- Run your image:
docker run --publish 5000:5000 --env-file .env snippets-voicemail-transcription
- The application will run on port 5000
Build and Run Natively
1. Replace environment variables 2. From command line run, python3 app.py
