We studied the effect of pause-internal phonetic particles(PINTs) on recall for native and non-native listeners of Englishin a listening experiment with synthesized material that simulated a university lecture. Using a neural speech synthesizertrained on recorded lectures with PINTs annotations, we generated three distinct conditions: a base version, a “silence” version where non-silence PINTs were replaced with silence, anda “nopints” version where all PINTs, including silences, wereremoved. Half of the participants were informed they were listening to computer-generated audio, while the other half weretold the audio was recorded with a poor-quality microphone.We found that neither the condition nor the participants’ nativelanguage significantly affected their overall score, and the presence of PINTs before critical information had a negative effecton recall. This study highlights the importance of consideringPINTs for educational purposes in speech synthesis systems.
