“…The results appear to replicate previous findings of activation in superior temporal cortex during speech processing compared to a tone discrimination baseline Jäncke et al, 2002;Demonet et al, 1992;Zatorre et al, 1992). However, they also suggest that the specific type of phonetic signal being processed will influence the character of these results, given weaker results for the Vowel condition than the Consonant condition in these regions.…”

“…The fact that this region of right STG showed some amount of activation in both of these speech conditions, in addition to the Tone Sweep condition, might reflect its involvement in the automatic processing of all types of auditory stimuli containing rapidly changing constituents, regardless of what type of cue is being actively attended to. This is supported by recent work by Jäncke et al (2002), which shows stronger activation in specific regions of STG/STS during passive listening to CV syllables, compared to vowels alone.…”

“…Multiple studies have identified bilateral regions of increased activation in the posterior STG and STS during speech processing, compared to nonspeech processing. This result has been observed across many types of speech processing tasks, including listening passively to speech compared to noise (Jäncke et al, 2002); listening to vocal sounds of all types compared to nonspeech environmental noises, distorted speech, noise with a speech-like amplitude envelope, and bells (Belin et al, 2000); listening to intelligible sentences compared to the same sentences that have been spectrally modified to destroy intelligibility (Scott et al, 2000) nonwords compared to sinewave analogues (Vouloumanos et al, 2001); listening to sentences, lists of words, and pseudowords compared to tones or noise (Binder et al, 2000); listening to words in one's native language compared to words in a foreign language (Schlosser et al, 1998); rhyme and phoneme monitoring compared to tones or noise (Demonet et al, 1992;Jäncke et al, 2002;Zatorre et al, 1992); and discriminating the initial phoneme in a pair of words compared to tones .…”

“…PET and fMRI studies have found left IFG activation during phoneme monitoring (Demonet et al, 1992;Jäncke et al, 2002), syllable counting (Poldrack et al, 1999), phoneme discrimination Fiez et al, 1995), and rhyme judgment (Poldrack et al, 2001;Zatorre et al, 1992). Burton (2001) has sug-gested that the common factor among these studies is that they require participants to access higher-order phonological representations such as phonemes and syllables.…”

Speech perception involves recovering the phonetic form of speech from a dynamic auditory signal containing both time-varying and steady-state cues. We examined the roles of inferior frontal and superior temporal cortex in processing these aspects of auditory speech and nonspeech signals. Event-related functional magnetic resonance imaging was used to record activation in superior temporal gyrus (STG) and inferior frontal gyrus (IFG) while participants discriminated pairs of either speech syllables or nonspeech tones. Speech stimuli differed in either the consonant or the vowel portion of the syllable, whereas the nonspeech signals consisted of sinewave tones differing along either a dynamic or a spectral dimension. Analyses failed to identify regions of activation that clearly contrasted the speech and nonspeech conditions. However, we did identify regions in the posterior portion of left and right STG and left IFG yielding greater activation for both speech and nonspeech conditions that involved rapid temporal discrimination, compared to speech and nonspeech conditions involving spectral discrimination. The results suggest that, when semantic and lexical factors are adequately ruled out, there is significant overlap in the brain regions involved in processing the rapid temporal characteristics of both speech and nonspeech signals.

“…Recent studies using invasive electrophysiological recordings have demonstrated that statistical regularities in the basic acoustic properties of environmental sounds shape the neural circuitry in the primary auditory cortex of animals (Nelken, 2004;Zhang et al, 2001). Whether and to what extent neural processing in non-primary auditory cortical areas, for example those involved in phonetic-phonological processing of speech (Jacquemot et al, 2003;Jäncke et al, 2002), are similarly tuned to statistical regularities in abstract properties of complex sounds, is unknown. In humans, speech constitutes the most relevant complex sound which is routinely dealt with.…”

Objective: Ample behavioral evidence suggests that distributional properties of the language environment influence the processing of speech. Yet, how these characteristics are reflected in neural processes remains largely unknown. The present ERP study investigates neurophysiological correlates of phonotactic probability: the distributional frequency of phoneme combinations. Methods: We employed an ERP measure indicative of experience-dependent auditory memory traces, the mismatch negativity (MMN). We presented pairs of non-words that differed by the degree of phonotactic probability in a modified passive oddball design that minimizes the contribution of acoustic processes. Results: In Experiment 1 the non-word with high phonotactic probability (notsel) elicited a significantly enhanced MMN as compared to the non-word with low phonotactic probability (notkel). In Experiment 2 this finding was replicated with a non-word pair with a smaller acoustic difference (notsel-notfel). An MMN enhancement was not observed in a third acoustic control experiment with stimuli having comparable phonotactic probability (so-fo). Conclusions: Our data suggest that auditory cortical responses to phoneme clusters are modulated by statistical regularities of phoneme combinations. Significance: This study indicates that the language environment is relevant in shaping the neural processing of speech. Furthermore, it provides a potentially useful design for investigating implicit phonological processing in children with anomalous language functions like dyslexia.
