Nemotron voice model settings - problems with low pitched voice

The new voice mode doesn't work with my dark very low pitched voice (lower than James Earl Jones, Darth Vader). According to the internet Nemotron has parameters to compensate for that, like less noise filtering, low frequency cut-off etc. Can these parameters be exposed in the settings for vs code? And if they are already exposed can they be documented?

My current experience:
- I say "hey code"
- Nothing happens
- I say "hey code" in a higher pitch, which strains my voice.
- Chat mode activates.
- I say something in Dutch, my native language.
- English gibberish appears on the screen.
- I say something in English.
- English gibberish appears on the screen.

I did use multiple different microphones and played around with the windows settings, but the result stays the same.
