Event-related potentials (ERPs) were utilized to study brain activity while subjects listened to speech and nonspeech stimuli. The effect of duplex perception was exploited, in which listeners perceive formant transitions that are isolated as nonspeech "chirps," but perceive formant transitions that are embedded in synthetic syllables as unique linguistic events with no chirp-like sounds heard at all (Mattingly et al., 1971). Brain ERPs were recorded while subjects listened to and silently… 
Auditory Spectral Integration in Nontraditional Speech Cues in Diotic and Dichotic Listening
Underlying auditory processes in speech perception were explored, and results indicated that auditory spectral integration may occur above the auditory periphery but at stages more intermediate rather than central.
Spectral Integration of Dynamic Cues in the Perception of Syllable-Initial Stops
Results indicate that virtual F3 transitions can provide phonetic information to the perceptual system and that auditory spectral integration (completed by the central auditory system) may play a significant role in speech perception.
Effect of continuous speech and non-speech signals on stuttering frequency in adults who stutter
Findings are consistent with the notion that the percept of a second signal as speech or non-speech can respectively augment or attenuate the potency for reducing stuttering frequency.

This review presents an account of the areas and circuits of the brain that are thought to be involved in such cognitive functions as memory, affect and consciousness, and convincing evidence is presented that these high level functions are represented in a complex organization of interconnected cortical and subcortical areas.

Late Responses to Speech Stimuli as Demonstrated by Electroencephalography Utilizing a Summing Computer Technique
Whether speech, considered to be a species‐specific function, did in fact elicit different EEG behavior than nonlinguistic signals is determined.
The effect of attention on the average evoked response to speech sounds.
Lateralization of phonetic and pitch discrimination in speech processing.
Processing changes in pitch produced activation of the right prefrontal cortex, consistent with the importance of right-hemisphere mechanisms in pitch perception.

Auditory Speech Processing in the Left Temporal Lobe: An Electrical Interference Study
Auditory syllable discrimination, identification, and comprehension were investigated by direct cortical electrical interference in three patients with indwelling subdural electrode arrays, suggesting that lower-level auditory speech functions can operate independent of higher-level processes, as claimed by traditional hierarchical models.
The role of “chirp” identification in duplex perception
Results suggest that listeners do not need to perceptually integrate F2 transitions or F2 and F3 transition pairs with the base in duplex perception, and it appears that listeners identify the chirps as speech without reference to the base.
Duplex perception: Confirmation of fusion
Both experiments support the hypothesis that the speech percept in the duplex situation results from dichotic fusion at a relatively early stage in processing.
