This should be doable if you add
or renpy.get_statement_name() == "say-nvl"
to the bigger conditional inside the "add_speech_pauses" function. So it should look like:
def add_speech_pauses(text_input): if prev_filter: text_input = prev_filter(text_input) if persistent.speech_pauses is not True or preferences.text_cps == 0 or renpy.get_statement_name() == "say-nvl": return text_input return speech_pause_adder(text_input)
