You can use STT and include a workflow that automatically extracts the requirements (filters all the um's, ah's, pauses) and it becomes more like an interaction where you act as the Product Owner/Manager and Codex is your Architect/Dev.

At least, that's how I code through my phone. But it does require some forethought in establishing your automated workflows. I'm at the point where my entire dev system has established templates for CI/CD so I can preview work in staging and production is still a manual step (obviously).
