Fundamental frequency as an acoustic cue to accent perception
Language and speech
It is generally recognized that the most significant cue to accent location is fundamental frequency (F0) in both Japanese and English. Furthermore, it is widely believed that a syllable is perceived as accented if the syllable contains an F0 peak. However, Sugito (1972) found that, in Japanese, if an F0 peak is followed by a steep F0 fall, the syllable preceding the F0 peak may be perceived as accented. In this article we present two experiments which investigate the relationship between F0 peak and F0 fall rate in accent perception for Japanese and English. The first experiment confirms that, for Japanese, both F0 peak location and F0 fall rate affect listeners' judgements of accent location. Specifically, the later the F0 peak occurs in a given syllable, relative to the syllable boundary, the greater the F0 fall rate necessary for listeners to perceive the preceding syllable as accented. The second experiment shows that this phenomenon is not unique to Japanese: Perception of...
Prominence in Japanese Is Not Only Cued Acoustically
2020
This paper studies focal prominence in Japanese. Japanese is a mora-timed pitch-accented agglutinative language. It realizes its accent by a falling H*L bi-tonal contour, and lexical H*L pitch accents trigger downstep. In the literature there are two contradictory views on Japanese focus. One is that Japanese focus has acoustic focal cues: F0-rise on the focused word and reduction in the post-focal areas. The other is that Japanese accent is relatively weak and is not principally used to convey discourse information. In this paper, we would like to investigate which view is correct. We conducted a production and a perception experiment on the focal prominence on the phrase-level. The previous works on Japanese focus were mainly on Accented (A-) words. Our study covered both A-words and Unaccented (U-) words so that we could analyze the acoustic properties of Japanese focal prominence overall. We also conducted an auditory rating task of prominence on spontaneous speech in Japanese t...

This study investigated acoustic manipulation of Japanese prosody by English speakers. It examined how English speakers who are fluent in Japanese realize Japanese lexical accent, and whether they transfer acoustic features associated with English word stress to Japanese lexical accent. The study showed that the more fluent speakers of Japanese used F0 to indicate lexical accent without increasing mora duration, whereas less fluent speakers did not, but instead increased the duration of accented vowels. The study also showed that the English speakers were unable to produce non-accented words, and instead placed an accent in a word, which triggered downstep and hence wrong phrase intonation.
The perception of non-native lexical pitch accent by speakers of 'accentless' Japanese dialects
While Standard (Tokyo) Japanese has a lexical tonal system known as a system of 'lexical pitch accent', there are some varieties of Japanese, called 'accentless' dialects, which do not have any lexical tonal phenomena. We investigated how the speakers of those dialects perceive Standard Japanese accent, which is nonexistent in their native dialect's phonology. The results of the Sequence Recall task showed that their scores were lower than those of control (Standard Japanese) participants. We also found a large variance in the results of 'accentless' participants, which was probably caused by their exposure to Standard Japanese.
Accuracy and Stability in English Speakers’ Production of Japanese Pitch Accent
Language and Speech
Standard Japanese uses pitch accent to distinguish words such as initially-accented hashi “chopsticks” and finally-accented hashi “bridge.” Research on the second language acquisition of pitch accent shows considerable variation: in accuracy scores in identification, in different dominant accent types in production, and in the unstable accent types of repeated words. This study investigates pitch accent production in English-speaking learners of Japanese, asking how accuracy and stability vary (a) with amount of Japanese experience and (b) between learners. Two groups of learners (13 less experienced; 8 more experienced) produced 180 words in three contexts (e.g., ame “rain,” ame da “it’s rain,” and ame ga furu “rain falls”). Three Japanese phoneticians identified the accent types of the words that the learners produced. The results showed no difference in accuracy or stability between the two groups and little inter-learner variation in accuracy: all had low accuracy. Although some...

The occurrence of peaks and valleys of the F0 contour of an utterance on non-prominent syllables in American English (as on the -ing or a-in reading again) raise the question of how to label these inflection points. Analysis of samples from prosodically-labelled corpora of natural speech * (MIT Maptask and BU FM Radio News) show that H* !H* sequences with an f0 peak on a weak syllable between them can occur quite commonly in continuous communicative speech. Informal listening suggests that the alignment of these f0 peaks with specific non-prominent syllables between the two accented syllables can change the perceived relative prominences of the accents. This observation is supported by results of perceptual experiments using synthesized F0 contours: the location of the peak in the weak syllable can shift the perceived strongest prominence from the initial syllable to the final syllable of a word like lemonade or millionaire. These findings illustrate the pervasiveness of F0 inflection points that are not aligned with syllables perceived as prominent, and suggest that alignment of the inflection point is a critical aspect of the specification of an intonational contour.
Prominence marking in the Japanese intonation system
2008
Abstract: Japanese uses a variety of prosodic mechanisms to mark focal prominence, including local pitch range expansion, prosodic restructuring to set off the focal constituent, post-focal subordination, and prominence-lending boundary pitch movements, but (notably) not manipulation of accent. In this paper, we describe the Japanese intonation system within the Autosegmental-Metrical model of intonational phonology, and review these prosodic mechanisms that have been shown to mark focal prominence.
