Conference paper (peer-reviewed)abstract
- This paper reports the results of a pilot study, which examines the respiratory control exerted by chest and abdominal-muscles during the reading of a long text in the mother tongue (L1) and a targeted foreign language that is being learned (L2), with reference to syntax and prosody in Japanese and Swedish. Three datasets of read speech were obtained from Swedish speakers (SwL1), Swedish learners of Japanese (SwL2), and Japanese speakers (JL1). The results showed that the subjects used respiratory control differently while reading L1 texts and L2 texts, respectively. Both SwL1 and JL1 used chest and abdominal-muscles almost simultaneously, and the peaks of their muscular movements co-occurred at the onset of major syntactic units such as sentences and clauses. SwL2 used more chest muscles than abdominal-muscles, with muscular movements being more frequent, irregular, and small. There was no significant difference between JL1 and Swedish L1 and L2 in terms of the tonal control (pitch range). Some pitch peaks and pauses that appeared at the major syntactic boundaries coincided with the peaks of the muscular movements, but other pitch peaks and pauses did not. These results led to the hypothesis that the acquisition of intonation precedes that of respiratory control in L2 learning.

Acoustic properties of implosives in Bantu Mpiemo
- 2012
-
In: Proceedings from FONETIK 2012. - 9789163709852 ; , s. 73-76
-
Conference paper (peer-reviewed)abstract
- Previous studies on implosives have shown a great diversity in the production of implosives among the languages in the world. In the light of this, this paper seeks to identify the acoustic phonetic properties of a Bantu language, Mpiemo, spoken in the Central African Republic. One of the strong acoustic correlates of implosives is increasing voicing amplitude during occlusion, which contrasts with a decreasing voicing amplitude for voiced plosives. Another acoustic property of implosives is the increased F0 during the occlusion, which continues all the way to the end of the following vowel.

Analysis of text-reading speech produced by Japanese primary school children (age 6-12): Focus on Topic-Comment structure
- 2024

In: Proceedings from FONETIK 2024, Stockholm. - 0282-6690. ; , s. 49-54
-
Journal article (other academic/artistic)abstract
- Japanese primary school children (ages 6-12) text-reading speech is analyzed. The reading time indicates that reading aloud fluency develops in two steps: between grades 1-2 and 3-4. Most children insert a pause after the topic particle wa, regardless of punctuation, which agrees with previously reported adult performance. In contrast, the intonation captured as F0 peak relation between Topic and Comment changes constantly along with the primary school years and is still far from those produced by adults.
