“…Nevertheless, the current study showed that both LHD and RHD patients were equally impaired in the tone production task in comparison to controls. This result accords with findings for lexical tone disruption in Shona [7], which showed that there is no difference in the tones produced by LHD vs. RHD Shona speakers.…”

“…Lesions to the LH are associated with tone disruption, whereas abnormal tonal production hardly occurs in patients with RH damage [1][2][3], because tones, involving rapidly changing temporal cues, have been linked with processing in the LH [4]. However, fMRI research shows that tone production is less lateralized than other elements of speech sounds [5], and there are studies demonstrating that both LHD and RHD groups were equally impaired in tone production tasks in comparison to controls [6][7], which raises the question that where tone is processed in the brain.…”

This study identifies the acoustic characteristics of tones produced by Mandarin brain-damaged patients. We investigate the F0 characteristics of the patients' tone productions and compare them with a control group of healthy speakers. The results show tone disruption in patients with brain damage in either the left or the right hemisphere. Even patients' tone productions that were correctly identified by Mandarin native speakers were acoustically different from the ones produced by healthy speakers. The patterns of tone disruption in Mandarin brain-damaged patients might be caused by damage to the motor function in the brain.

“…Most importantly, we found that the left STG, a region critical for speech and nonspeech pitch processing widely demonstrated in auditory research [Gandour and Dardarananda, ; Gandour, ; Kadyamusuma et al, ; Liang and van Heuven, ; Binder et al, ; Price et al, ; Zatorre et al, ; Gandour et al, ; Klein et al, ; Luo et al, ; Liu et al, ; Wang et al, ; Wong et al, ; Xu et al, ; Zhang et al, ], was not involved in lexical tone reading in our experiment. The left posterior middle/medial temporal gyrus at BA 19 was indeed activated in our study, but it is close to the fusiform gyrus and is spatially different from the STG mediating auditory tone perception.…”

Research on how lexical tone is neuroanatomically represented in the human brain is central to our understanding of cortical regions subserving language. Past studies have exclusively focused on tone perception of the spoken language, and little is known as to the lexical tone processing in reading visual words and its associated brain mechanisms. In this study, we performed two experiments to identify neural substrates in Chinese tone reading. First, we used a tone judgment paradigm to investigate tone processing of visually presented Chinese characters. We found that, relative to baseline, tone perception of printed Chinese characters were mediated by strong brain activation in bilateral frontal regions, left inferior parietal lobule, left posterior middle/medial temporal gyrus, left inferior temporal region, bilateral visual systems, and cerebellum. Surprisingly, no activation was found in superior temporal regions, brain sites well known for speech tone processing. In activation likelihood estimation (ALE) meta-analysis to combine results of relevant published studies, we attempted to elucidate whether the left temporal cortex activities identified in Experiment one is consistent with those found in previous studies of auditory lexical tone perception. ALE results showed that only the left superior temporal gyrus and putamen were critical in auditory lexical tone processing. These findings suggest that activation in the superior temporal cortex associated with lexical tone perception is modality-dependent.

“…In the clinical arena of speech pathology, a minimal pair word list can be utilized to assess tone production and perception ability in individuals with voice, speech, language, and hearing disorders. Recent studies provided evidence that these communication disorders can negatively affect tone manipulation or perception in individuals who speak tone languages (Ciocca, Whitehill & Ma Ka Yin, 2004;Jones, 2016;Kadyamusuma, De Bleser & Mayer, 2011;Nguyen, et al, 2009;Van der Merwe & Le Roux, 2014a: 135-140;2014b;Wong, Perrachione, Gunasekera, Chandrasekaran, 2009). Tone production ability could be compromised by neuromotor speech disorders like dysarthria due to cerebral palsy, Parkinson's disease or motor neuron disease and apraxia of speech due to stroke.…”

This study reports on the development of a Setswana tonal minimal pair word list, which could be implemented as research tool in the field of Bantu language linguistics and in speech pathology in South Africa. The development of the list was conducted in four phases. These are described as four separate studies. All involved Setswana L1 participants living in the urban areas of Gauteng. In Study 1, a 45-pair preliminary list was compiled from dictionaries. During Study 2, eleven L1 speakers' familiarity with each word was determined. Based on these results the list was narrowed down to 20 pairs. Study 3 entailed the validation of pictorial stimuli, which illustrate the target words. Ten different participants took part. Four pairs were not consistently familiar and were removed, resulting in the experimental list of 16 pairs. This list was validated in Study 4 and involved nine typical L1 speakers and five listeners. Word-specific analyses revealed that some words had a negative impact on the results. Six pairs were removed. A final list of 10 pairs rendered results more aligned to the expectation of typical speakers and listeners. Validation should continue to determine applicability in populations from exclusively rural or urban areas.
