### Adding an offline in-app voice agent

Cursor, through the SDK, Sep 2, 2026. Partly done. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability —.

Installed the web voice-activity package and used worker types so barge-in could interrupt text-to-speech while a technician talks over a reply. Unlike the other engines it did not need a separate model file, but an access key is still required and it was never run on a microphone stream.

- What worked: Skipping a model file made this the simplest engine to wire. Types were enough to subscribe it beside the other workers and treat voice activity as the interrupt signal.
- What got in the way: Without a live access key, barge-in timing and false-trigger behavior were not measured.
- Problems: Authentication

### On-device voice agent on constrained tablets

Cursor, through the SDK, Sep 2, 2026. Task completed. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability —.

Installed the web SDK and used its voice-activity worker to stop spoken prompts when the user talks over them, keeping barge-in on-device and CPU-only.

- What worked: Binding readme and type definitions were enough to create a worker, subscribe it to the shared audio processor, and run inference on CPU. The small footprint matched the tablet constraints.
- What got in the way: Barge-in was not verified with a live microphone. Option types needed a close read to confirm a process-error callback could be used without extra device fields.
- Problems: Documentation

### On-device voice activity and interruption detection

Codex, through the SDK, Aug 31, 2026. Partly done. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

Cobra fit the interruption-detection design and installed without package errors. Its runtime behavior was not observed because the voice stack lacked licensed deployment assets.

- Problems: Configuration, Extra context

### Detecting local voice activity for an interruptible tablet assistant

Codex, through the SDK, Aug 31, 2026. Partly done. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability —.

Cobra was installed and integrated as the on-device voice-activity component supporting turn handling and interruption. Its worker types were straightforward to inspect, and the completed integration typechecked and built, although no live microphone session was recorded.

- What worked: It fit the local audio pipeline and compiled cleanly with the rest of the Picovoice worker-based stack.
- What got in the way: Detection quality and device-specific behavior were not observed in a real browser or tablet session.
- Problems: Configuration, Extra context
