Codex Voice Mode Performance Reveals Mixed Results in Testing

Codex Voice Mode demonstrates uneven performance across different use cases. The system shows adequate capability for controlled computer tasks with discrete steps, but struggles with live document editing and calendar navigation errors. To manage usage constraints, the model 5.6 terra medium is recommended, though at the cost of reduced reasoning ability. The system automatically shuts down after 90 minutes, requiring manual restart. The interface presents challenges when spanning multiple monitors, with limited visibility of on-screen content. Screenshot limitations require more specific location references. Background audio or simultaneous speech confuses the system. However, the tool proved valuable for site navigation and proactively suggesting workarounds for user-reported issues.
