Enable Feature

To enable Filler Words, use the following parameter in the query string when you call Deepgram’s /listen endpoint :

model=nova-2&filler_words=true

ℹ️
Currently, Filler Words are only available for Deepgram's Nova and Nova-2 general models.

Deepgram is capable of transcribing the following filler words:

uh
um
mhmm
mm-mm
uh-uh
uh-huh
nuh-uh

These words will always be transcribed with the spelling listed above, regardless of their spoken duration (i.e., Deepgram will never transcribe "uhhhh" instead of "uh").

When filler_words=false or the parameter is not set, the two most common fillers, "uh" and "um", are stripped out of the transcript to improve readability.
