In the below are:
"stream_number" is not accessed
"stream_position" is not accessed

Can that be the reason that the output of:
"import pyttsx3

def onWord(name, location, length):
print ('word', name, location, length)
if location > 10:
engine.stop()
engine = pyttsx3.init()
engine.connect('started-word', onWord)
engine.say('The quick brown fox jumped over the lazy dog.')
engine.runAndWait()"

is still:
"word None 1 0
