To be quite honest I haven't really thought deeply about the CVR for years.
Most crew regard it as a system sitting back doing its own thing to be analyzed when necessary.
During an emergency the priority will always be getting the issue resolved and getting the aircraft safely down.
If I had a crew member annunciating every detail for the benefit of the CVR then I would be VERY concerned as to what his priorities were.
Is he was working with me to achieve a safe outcome or is he working for the crash investigators for a comprehensive report?
