Mandarin Tone

Abstract Using a semi-spontaneous speech corpus, we present evidence from computational modelling of tonal productions from Mandarin-speaking children (4- to 11-years old) and adults, showing that children exceed the adult-level tonal distinction at the age of 7 to 8 years using F0 cues, but do not reach the high adult-level distinction using spectral cues even at the age of 10 to 11 years. The difference in the developmental curves of F0 and spectral cues suggests that, in Mandarin tone production, secondary cues continue to develop even after the mastery of primary cues.

Mandarin Tone

This study examined how native speakers of Australian English and French, nontone languages with different lexical stress properties, perceived Mandarin tones in a sentence environment according to their native sentence intonation categories (i-Categories) in connected speech. Results showed that both English and French speakers categorized Mandarin tones primarily on the phonetic similarities of the pitch contours between the Mandarin tones and their native i-Categories. Moreover, French but not English speakers were able to detect the fine-detailed phonetic differences between Tone 3 (T3) and Tone 4 (T4; i.e., low or low-falling tone vs. high-falling tone), which suggests that the stress differences between these languages may affect nonnative tone perception: English uses lexical stress, whereas French does not. In the discrimination task, the French listeners’ performance was better than that of the English listeners. For each group, discrimination of the Tone 1 (T1)–T4 and Tone 2 (T2)–T3 pairs was consistently and significantly lower than that of the other tone pairs, and the difference between T1-T4 and T2-T3 was significant. Discrimination of the Mandarin tone pairs was not fully predicted by pairwise categorizations to native i-Categories, however. Some discrimination differences were observed among tone pairs showing the same assimilation patterns. Phonetic overlaps in native i-Category choices for the Mandarin tones, strength of categorization (So, 2012), and tonal coarticulation effects (Xu, 1994, 1997) may offer possible accounts of these discrepancies between categorization and discrimination performance. These findings support the perceptual assimilation model for suprasegmentals (So & Best, 2008, 2010a, 2010b, 2011, 2013), extended to categorization of nonnative tone words within sentence contexts to native i-Categories.

The Impact

PurposeThis study investigated the impact of metaphoric actions—head nods and hand gestures—in producing Mandarin tones for first language (L1) and second language (L2) speakers.MethodIn 2 experiments, participants imitated videos of Mandarin tones produced under 3 conditions: (a) speech alone, (b) speech + head nods, and (c) speech + hand gestures. Fundamental frequency was recorded for both L1 (Experiment 1) and L2 (Experiment 2a) speakers, and the output of the L2 speakers was rated for tonal accuracy by 7 native Mandarin judges (Experiment 2b).ResultsExperiment 1 showed that 12 L1 speakers' fundamental frequency spectral data did not differ among the 3 conditions. In Experiment 2a, the conditions did not affect the production of 24 English speakers for the most part, but there was some evidence that hand gestures helped Tone 4. In Experiment 2b, native Mandarin judges found limited conditional differences in L2 productions, with Tone 3 showing a slight head nods benefit in a subset of “correct” L2 tokens.ConclusionResults suggest that metaphoric bodily actions do not influence the lowest levels of L1 speech production in a tonal language and may play a very modest role during preliminary L2 learning.

Purpose The purpose of this study was to examine the aging effects on the categorical perception (CP) of Mandarin lexical Tones 1–4 and Tones 1–2 in noise. It also investigated whether listeners' categorical tone perception in noise correlated with their general tone identification of 20 natural vowel-plus-tone signals in noise. Method Twelve younger and 12 older listeners with normal hearing were recruited in both tone identification and discrimination tasks in a CP paradigm where fundamental frequency contours of target stimuli varied systematically from the flat tone (Tone 1) to the rising/falling tones (Tones 2/4). Both tasks were conducted in quiet and noise with signal-to-noise ratios set at −5 and −10 dB, respectively, and general tone identification of natural speech signals was also tested in noise conditions. Results Compared with younger listeners, older listeners had shallower identification slopes and smaller discrimination peakedness in Tones 1–2/4 perception in all listening conditions, except for Tones 1–4 perception in quiet where no group differences were found. Meanwhile, noise affected Tones 1–2/4 perception: The signal-to-noise ratio condition at −10 dB brought shallower slope in Tones 1–2/4 identification and less peakedness in Tones 1–4 discrimination for both listener groups. Older listeners' CP in noise, the identification slopes in particular, positively correlated with their general tone identification in noise, but such correlations were partially missing for younger listeners. Conclusions Both aging and the presence of speech-shaped noise significantly reduced the CP of Mandarin Tones 1–2/4. Listeners' Mandarin tone recognition may be related to their CP of Mandarin tones.

Purpose The purpose of the study was to examine the aging effect on the categorical perception of Mandarin Chinese Tone 2 (rising F0 pitch contour) and Tone 3 (falling-then-rising F0 pitch contour) as well as on the thresholds of pitch contour discrimination. Method Three experiments of Mandarin tone perception were conducted for younger and older listeners with Mandarin Chinese as the native language. The first 2 experiments were in the categorical perception paradigm: tone identification and tone discrimination for a series of stimuli, the F0 contour of which systematically varied from Tone 2 to Tone 3. In the third experiment, the just-noticeable differences of pitch contour discrimination were measured for both groups. Results In the measures of categorical perception, older listeners showed significantly shallower slopes in the tone identification function and significantly smaller peakedness in the tone discrimination function compared with younger listeners. Moreover, the thresholds of pitch contour discrimination were significantly higher for older listeners than for younger listeners. Conclusion These results suggest that aging reduced the categoricality of Mandarin tone perception and worsened the psychoacoustic capacity to discriminate pitch contour changes, thereby possibly leading to older listeners' difficulty in identifying Tones 2 and 3.

The article discusses unprepared reading in a non-native language and shows it to have all the signs of spontaneity that are traditionally considered integral characteristics of any spontaneous speech: hesitation pauses, both physical (ɭ) and filled with non-speech sounds (uh, m-m), word breaks, reading the whole word or part of it by syllables, vocalization of a consonant, and so forth. The material for the analysis included 40 monologues of reading the story by M. Zoshchenko Fantasy Shirt and a non-plot excerpt from V. Korolenko’s story The Blind Musician recorded from 20 Chinese informants. All the monologues are included in the block of Russian interfering speech of the Chinese as part of the monologic speech corpus Ba­lanced Annotated Text Library. As the analysis showed, it is more often that there is not one sign of spontaneity but a whole complex of such signs, and together they fill hesitation pauses, help the speaker to control the quality of speech or correct what was said, etc. In addition, the occurrence of various signs of spontaneity in the course of unprepared reading is closely related to the individual characteristics of the speaker/reader. In general, we have found that there are more signs of spontaneity in the speech of men (3,244 cases; 40.7 %) than in the speech of women (2,049; 27.7 %), in the speech of informants with a lower level of proficiency in Russian B2 (2,993; 37.9 %) than in the speech of informants with a higher level C1 (2,300; 30.8 %), in the speech of extroverts (1,521; 38 %) than in the speech of ambiverts (1,694; 35,2 %) and introverts (2,078; 31,7 %). As to the type of the source text, there turned out to be more signs of spontaneity in monologues of reading a plot text than in monologues of reading a non-plot text (3,031; 40.3 vs 2,283; 31 %). The paper concludes that reading should be recognized as a spontaneous type of speech activity.

Intonational Phrases

The objective of this paper is to describe the prosodic features of the final intonation contour of minor intonational phrases (ip) and the tonemes of major intonational phrases (IP) in Mexico City’s Spanish variety. The speech data was taken from a spontaneous speech corpus made from speakers from two social networks: neighborhood and labor. Final intonation contours of ip show a predominantly rising movement. These contours are generally produced with greater length in the last syllable of the ip, which represents the most significant difference between both networks in the case of oxitone endings. On the other hand, tonemes are predominantly descendant, although the circumflex accent has an important number of cases within the data set. Tonemes produced by the neighborhood network are produced with larger length than those from the labor network.

The Difference

The gut microbiome is essential to human health. However, little is known about the influence of the environment versus host-related factors (e.g. genetic background, sex, age, and body mass) in the formation of human intestinal microflora. Here, we present evidence in support of the importance of host-related factors in the establishment and maintenance of individual gut assemblages. We collected fecal samples (n = 249) from 44 Korean naval trainees and 39 healthy people living in Korea over eight weeks and sequenced the bacterial 16S rRNA genes. The following hypotheses were tested: 1) microbiome function is linked to its diversity, community structure, and genetic host-related factors, and 2) preexisting host-related factors have a more significant effect on gut microbiome formation and composition than environmental factors. For each individual, the difference between the initial gut microbiota and that after eight weeks was negligible even though the 44 naval trainees lived in the same area and received the same diet, the same amount of exercise, and the same amount of physical stress during the study. This suggests that host-related factors, rather than environmental factors, is a key determinant of individual gut microflora. Moreover, eight weeks of physical training and experiencing the same environmental conditions resulted in an increase in the species Bifidobacterium, Faecalibacterium, and Roseburia in most trainees, suggesting a healthier intestinal environment.

Choice Tasks

Updating predictions about which stimuli are associated with reward is an important aspect of adaptive behaviour believed to relate to prediction errors, the difference between experienced and predicted outcomes. Behavioural sensitivity to prediction errors flexibly adapts to environmental statistics. Prediction errors also influence affective states during risky choice tasks that do not require learning, but the relationship between emotions and adaptive behaviour is unknown. Here, using computational modelling we found that mood dynamics, like behaviour, are sensitive to learning-relevant model variables (i.e., probability prediction error). Unlike behaviour, mood dynamics are not sensitive to model variables that influence choice (i.e., expected value), and increasing volatility does not reduce how many trials influence affective state. Finally, depressive symptoms reduce overall mood more in volatile than stable environments. Our findings suggest that mood dynamics are selective for variables relevant to adaptive behaviour and suggest a greater role for mood in learning than choice.
