Recording and browser speech services depend on permissions and may involve external providers. AI modes can download models; conventional DSP is described separately. Review every proposed cut, keep originals and backups, and interpret voice measurements as observations rather than emotion, health or proficiency diagnoses.
Keep project or progress backups when a tool offers them. Browser storage and download behavior vary by tool and browser.
