enable_backchannel
: set to true
to enable backchannel. Default to false
.
backchannel_frequency
: When our engine determines that a backchannel is possible and appropriate here, you don’t necessarily always want
to backchannel. Humans often only backchannel at some places, not all possible cases. Therefore, this field controls how often
the backchannel is triggered, with 0 being never, 1 being always when possible. The default is 0.8.
backchannel_words
: The words that the agent can use as backchannel. The default is different for each language, and for each
voice provider, as some voice provider does not have support for some of the words. The following tab contains the default backchannel
words for each language and voice provider. You can overwrite this field to customize the backchannel words.
Note that certain voices do not work too well with certain words, so it’s recommended to expeirment before adding any words.
