Altering Voice envelope Rise times without altering formants?

Hi!

I see great way to speed up, slow down, change pitch and tempo, however is there a way to alter the voice envelope rise time without altering the rate of change of the vocal formants? As in the speech spectrogram?

Thanks for any help you can offer!

You need to use a program such as Antares AutoTune with a supported host application.
