Tone Discrimination

Aims and objectives:The present study explored children’s discrimination capacities for lexical tones and consonants between 3 and 6 years of age and the effect of native language on this ability. Recent studies in infants have shown a perceptual rebound for non-native listeners during the second year of life, but only for lexical tones. However, the later stages of development, and particularly when children start pre-school, are yet not clear.Design:Discrimination abilities of 134 children were measured in three age groups between 3 and 6 years using a behavioural task where children detected a change in lexical tones or consonants. Children were either French monolinguals, French bilinguals exposed to an Asian tone language or French bilinguals exposed to a second non-tone language at home.Data and analysis:Overall, results indicated that higher detection scores for consonants were observed from 4 to 5 years, while for lexical tones the highest scores were observed only at 5–6 years. Moreover, bilingual children exposed to an Asian tone language had higher scores for tones compared to monolingual French children. Interestingly, both bilingual groups, whether exposed to an Asian tone language or to a non-tone language, had better scores for tones than for French consonants, while monolinguals performed equally with both.Conclusions:Language exposure from an early age influences phonological development and bilingualism seems to enhance the perception of prosodic information.Originality:This study is the first to show a different developmental trajectory for consonant and lexical-tone discrimination between 3 and 6 years according to the native language.Significance:Similar detection scores for tones and consonants for monolingual French children and better detection for tones than for consonants for both groups of bilinguals suggest that the perception of lexical tone is determined by both language-specific influences and non-linguistic/auditory processing during childhood.

Purpose Theoretical models and substantial research have proposed that general auditory sensitivity is a developmental foundation for speech perception and language acquisition. Nonetheless, controversies exist about the effectiveness of general auditory training in improving speech and language skills. This research investigated the relationships among general auditory sensitivity, phonemic speech perception, and word-level speech perception via the examination of pitch and lexical tone perception in children. Method Forty-eight typically developing 4- to 6-year-old Cantonese-speaking children were tested on the discrimination of the pitch patterns of lexical tones in synthetic stimuli, discrimination of naturally produced lexical tones, and identification of lexical tone in familiar words. Results The findings revealed that accurate lexical tone discrimination and identification did not necessarily entail the accurate discrimination of nonlinguistic stimuli that followed the pitch levels and pitch shapes of lexical tones. Although pitch discrimination and tone discrimination abilities were strongly correlated, accuracy in pitch discrimination was lower than that in tone discrimination, and nonspeech pitch discrimination ability did not precede linguistic tone discrimination in the developmental trajectory. Conclusions Contradicting the theoretical models, the findings of this study suggest that general auditory sensitivity and speech perception may not be causally or hierarchically related. The finding that accuracy in pitch discrimination is lower than that in tone discrimination suggests that comparable nonlinguistic auditory perceptual ability may not be necessary for accurate speech perception and language learning. The results cast doubt on the use of nonlinguistic auditory perceptual training to improve children's speech, language, and literacy abilities.

Tone Discrimination

Abstract The current study investigated how the role of pitch in one’s native language and L2 experience influenced musical melodic processing by testing Turkish and Mandarin Chinese advanced and beginning learners of English as an L2. Pitch has a lower functional load and shows a simpler pattern in Turkish than in Chinese as the former only contrasts between presence and the absence of pitch elevation, while the latter makes use of four different pitch contours lexically. Using the Musical Ear Test as the tool, we found that the Chinese listeners outperformed the Turkish listeners, and the advanced L2 learners outperformed the beginning learners. The Turkish listeners were further tested on their discrimination of bisyllabic Chinese lexical tones, and again an L2 advantage was observed. No significant difference was found for working memory between the beginning and advanced L2 learners. These results suggest that richness of tonal inventory of the native language is essential for triggering a music processing advantage, and on top of the tone language advantage, the L2 experience yields a further enhancement. Yet, unlike the tone language advantage that seems to relate to pitch expertise, learning an L2 seems to improve sound discrimination in general, and such improvement exhibits in non-native lexical tone discrimination.

Level Tone

AbstractL2 sounds present different kinds of challenges to learners at the phonetic, phonological, and lexical levels, but previous studies on L2 tone learning mostly focused on the phonetic and lexical levels. The present study employs an innovative technique to examine the role of prior tonal experience and musical training on forming novel abstract syllable-level tone categories. Eighty Cantonese and English musicians and nonmusicians completed two tasks: (a) AX tone discrimination and (b) incidental learning of artificial tone-segment connections (e.g., words beginning with an aspirated stop always carry a rising tone) with synthesized stimuli modeled on Thai. Although the four participant groups distinguished the target tones similarly well, Cantonese speakers showed abstract and implicit knowledge of the target tone-segment mappings after training but English speakers did not, regardless of their musical experience. This suggests that tone language experience, but not musical experience, is crucial for forming novel abstract syllable-level tone categories.

Production Accuracy

Purpose Previous studies reported that children acquire Cantonese tones before 3 years of age, supporting the assumption in models of phonological development that suprasegmental features are acquired rapidly and early in children. Yet, recent research found a large disparity in the age of Cantonese tone acquisition. This study investigated Cantonese tone development in 4- to 6-year-old children. Method Forty-eight 4- to 6-year-old Cantonese-speaking children and 28 mothers of the children labeled 30 pictures representing familiar words in the 6 tones in a picture-naming task and identified pictures representing words in different Cantonese tones in a picture-pointing task. To control for lexical biases in tone assessment, tone productions were low-pass filtered to eliminate lexical information. Five judges categorized the tones in filtered stimuli. Tone production accuracy, tone perception accuracy, and correlation between tone production and perception accuracy were examined. Results Children did not start to produce adultlike tones until 5 and 6 years of age. Four-year-olds produced none of the tones with adultlike accuracy. Five- and 6-year-olds attained adultlike productions in 2 (T5 and T6) to 3 (T4, T5, and T6) tones, respectively. Children made better progress in tone perception and achieved higher accuracy in perception than in production. However, children in all age groups perceived none of the tones as accurately as adults, except that T1 was perceived with adultlike accuracy by 6-year-olds. Only weak association was found between children's tone perception and production accuracy. Conclusions Contradicting to the long-held assumption that children acquire lexical tone rapidly and early before the mastery of segmentals, this study found that 4- to 6-year-old children have not mastered the perception or production of the full set of Cantonese tones in familiar monosyllabic words. Larger development was found in children's tone perception than tone production. The higher tone perception accuracy but weak correlation between tone perception and production abilities in children suggested that tone perception accuracy is not sufficient for children's tone production accuracy. The findings have clinical and theoretical implications.

Like the vast majority of Bantu languages, Chichewa is a tone language. The chapter begins with a brief introduction to the Chichewa tone system. The lexical tone patterns for noun and verb stems are taken up next. Lexical tones do not always surface on their input sponsor syllable due to the application of tone processes such as tone doubling, tone plateauing, and final retraction. These processes, all conditioned by phrase penult lengthening, are defined and illustrated in detail in this chapter, along with the OCP-motivated process, Meeussen’s Rule. The tonal properties of clitics and clitic-like nominal modifiers are shown to motivate the process of tone shift. The phonetics of tone and the accentual properties of the Chichewa tone system are discussed in the concluding sections.

This study examined how bilingualism in an atonal language, in addition to a tonal language, influences lexical and non-lexical tone perception and word learning during childhood. Forty children aged 5;3–7;2, bilingual either in English and Mandarin or English and another atonal language, were tested on Mandarin lexical tone discrimination, level-pitch sine-wave tone discrimination, and learning of novel words differing minimally in Mandarin lexical tone. Mandarin–English bilingual children discriminated between and learned novel words differing minimally in Mandarin lexical tone more accurately than their atonal–English bilingual peers. However, Mandarin–English and atonal–English bilingual children discriminated between level-pitch sine-wave tones with similar accuracy. Moreover, atonal–English bilingual children showed a tendency to perceive differing Mandarin lexical and level-pitch sine-wave tones as identical, whereas their Mandarin–English peers showed no such tendency. These results indicate that bilingualism in a tonal language in addition to an atonal language—but not bilingualism in two atonal languages—allows for continued sensitivity to lexical tone beyond infancy. Moreover, they suggest that although tonal–atonal bilingualism does not enhance sensitivity to differences in pitch between sine-wave tones beyond infancy any more effectively than atonal–atonal bilingualism, it protects against the development of biases to perceive differing lexical and non-lexical tones as identical. Together, the results indicate that, beyond infancy, tonal–atonal bilinguals process lexical tones using different cognitive mechanisms than atonal–atonal bilinguals, but that both groups process level-pitch non-lexical tone using the same cognitive mechanisms.

The effect of short term musical experience on lexical tone perception was examined by administering four hours of daily musical ear training to non-tone language speakers. After training, participants showed some improvement in a tone labeling task, but not a tone discrimination task; however, this improvement did not differ reliably from controls indicating that short-term musical training is thus far not able to replicate language effects observed among lifelong musicians, but some linguistic differences between musicians and nonmusicians may likely be due to experience, rather than individual differences or other factors.

Abstract The functions of acoustic-phonetic modifications in infant-directed speech (IDS) remain a question: do they specifically serve to facilitate language learning via enhanced phonemic contrasts (the hyperarticulation hypothesis) or primarily to improve communication via prosodic exaggeration (the prosodic hypothesis)? The study of lexical tones provides a unique opportunity to shed light on this, as lexical tones are phonemically contrastive, yet their primary cue, pitch, is also a prosodic cue. This study investigated Cantonese IDS and found increased intra-talker variation of lexical tones, which more likely posed a challenge to rather than facilitated phonetic learning. Although tonal space was expanded which could facilitate phonetic learning, its expansion was a function of overall intonational modifications. Similar findings were observed in speech to pets who should not benefit from larger phonemic distinction. We conclude that lexical-tone adjustments in IDS mainly serve to broadly enhance communication rather than specifically increase phonemic contrast for learners.

AbstractPrevious studies on bilingual children found intact tonal development at the initial stages of interaction between Cantonese and English in successive bilingual children, whereas children exposed to both languages from birth have not been studied in this regard. We examined the production of Cantonese tones by five simultaneous bilingual children longitudinally at 2;0 and 2;6, and compared them with age-matched monolingual children using auditory analysis. Our results showed that some bilingual children had a delay at 2;0, compared to their monolingual peers. Some bilingual children also exhibited a ‘high–low’ template in their production, resembling the pitch pattern of English trochaic words. These findings suggest a possible early interaction of the Cantonese and English prosodic systems in which bilingual children adopted the English stress pattern in Cantonese production. The time-point along the trajectory of phonological development is important in modulating whether cross-linguistic transfer can be observed.
