Devin's Voice Calls Move to a Live Speech Model, Cutting Straight to Call Controls
Cognition’s September 16, 2026 release notes for Devin upgrade voice calls to run on a live speech model, replacing the earlier, more turn-based voice mode with something closer to a real phone call.
Details
- Live speech model for calls: voice calls with Devin now run on a live speech model instead of the prior voice pipeline, aiming for more natural, lower-latency back-and-forth conversation
- Faster call start: starting a call now drops users straight into the call controls, with a ringtone playing while the connection is established, instead of a loading state
- Sessions wake as you type: sessions begin activating as soon as a user starts typing in the composer, so Devin is typically already spinning up by the time a message is sent
- Formatting-safe copy: copying messages now preserves formatting when pasted into email or documents, while still pasting as Markdown into code editors
- Configurable send shortcut: users can choose whether Enter or Cmd/Ctrl+Enter sends a message, under Settings → Personal → Send shortcut
- Security scans now mandatory: Devin Review always checks for security bugs on every review; the previous optional “Security scan” toggle has been removed
- Other interface refinements: skipped questions now display what was actually asked instead of a generic “no answer” label, sessions with VM issues show a direct “Reboot VM” action in the sidebar, and session dialogs were restyled to match the rest of the app
What happened next
The live-speech upgrade builds on the voice mode Cognition had already shipped for hands-free interaction with Devin, moving it toward something closer to a natural phone call rather than a request-and-wait exchange. Paired with sessions that start warming up the moment a user begins typing, the changes point at Cognition continuing to shave latency out of every step between a developer’s intent and Devin actually starting work.
