Citation Form

The purpose of this paper was to analyze the acoustic characteristics of Thai tones produced by tonal language speakers, namely Vietnamese and Burmese, and non-tonal language speakers, namely Khmer and Malay, in citation form and connected speech. The test words in citation form and connected speech comprised five tones, which were the Mid tone, the Low tone, the Falling tone, the High tone, and the Rising tone occurring in non-checked and checked syllables. The informants were twenty-four Vietnamese, Burmese, Khmer, and Malay native speakers with high experience in Thai (three speakers for each language) and low experience in Thai (three speakers for each language). The informants’ speech was recorded directly on to a computer. The fundamental frequencies (F0) of tones were measured using Praat Version 5.1.43 and then converted to semitones.

Low Tone

The Western dialect of Naxi has four lexical tones: High, Mid, Low and Rising; the latter is rare in the lexicon. Rising contours on monosyllables are frequent in connected speech, however, as a result of a process of syllable reduction: reduction of a morpheme carrying the High tone results in re-association of its tone to the syllable that precedes it in the sentence, creating a rising contour. An experiment (with one speaker and five listeners) establishes that there is not only one rising contour that originates in tonal reassociation, as reported in earlier descriptions, but two: Low-to-High and Mid-to-High – as could be expected by analogy with phenomena observed in Niger-Congo languages and elsewhere. A second set of experiments (same speaker; six listeners) investigates the reduction of Mid- and Low-tone syllables: they reduce to [] and [], respectively, and coalesce with the preceding syllable (in Naxi, syllabic structure is simply consonant + glide + vowel). Unlike High-tone syllable reduction, this process stops short of complete tonal de-linking. These experiments aim to provide a complete picture of syllable reduction patterns in Naxi. It is argued that the notions of floating tones and tonal reassociation can be usefully applied to the Naxi data.

<p style="text-align: justify;">The purpose of this study was to analysis of angklung sound intensity. The research method is using angklung musician 2 octaves. Each consists of two tube tone that sounded from the tone of G to G ', length and diameter of the tube every tone becomes independent variable, while intensity of the sound produced becomes dependent variable. Sound intensity is measured using a Sound Level Meter is placed with a constant distance. The result showed that G tone was a low tone which had a frequency of 49.5 Hz, first tube had 21.6 cm length and 4.1 cm diameter, second tube had 10.1 cm length and 3.4 cm diameter produced the sound intensity of 90.7 dB. G’ tone was a high tone which had a frequency of 99 Hz, first tube had 10 cm length and 3 cm diameter, second tube had 5.5 cm length and 2.1 cm diameter produced the sound intensity of 99.1 dB. It can be concluded that the higher the frequency, the greater the intensity of the sound produced. The shorter tube length and the smaller tube diameter, the greater the intensity of the sound. ©2016 JNSMR UIN Walisongo. All rights reserved.</p>

Prosodic Focus

Production and perception experiments were conducted to examine whether focus prosody varies by phrase-initial tones in Seoul Korean. We also trained an automatic classifier to locate prosodic focus within a sentence. Overall, focus prosody in Seoul Korean was weak and confusing in production, and poorly identified in perception. However, Seoul Korean’s focus prosody differed between phrase-initial low and high tones. The low tone group induced a smaller pitch increase by focus than the high tone group. The low tone group was also subject to a greater degree of confusion, although both tone groups showed some degree of confusion spanning the entire phrase as a focus effect. The identification rate was, therefore, approximately half in the low tone group (23.5%) compared to the high tone group (40%). In machine classification, the high tone group was also more accurately identified (high: 86% vs. low: 68%) when trained separately, and the machine’s general performance when the two tone groups were trained together was much superior to the human’s (machine: 65% vs. human: 32%). Although the focus prosody in Seoul Korean was weak and confusing, the identification rate of focus was higher under certain circumstances, which avers that focus prosody can vary within a single language.

Physiological Variations

Gastric tone may mediate gastric accommodation and emptying; however, it cannot be recorded by manometric methods. We have developed an electronic barostat that maintains a constant pressure (2 mmHg) within an air-filled bag and have validated the system in vitro and in vivo. In four conscious dogs, the bag was introduced orally into the stomach, and gastric tone was monitored from the barostat as variations in intrabag volume. Simultaneously, we recorded upper gut pressure activity by implanting manometric catheters. Studies were performed in fasting and fed (200-ml solid meal) dogs. The barostat system did not distort fasting motor activity. Intrabag volume correlated with manometrically measured fundic pressure activity. However, tonic changes undetected manometrically were clearly registered by the barostat. Meal induced marked changes in gastric tone. A receptive relaxation during feeding was followed by a low-tone accommodation period. Later, the barostat registered a sustained high tone until the return of the fasting pattern. We conclude that the electronic barostat measures physiological variations in gastric tone that are not recorded by conventional systems.

Pulmonary Vascular Bed

The effects of an increase in base-line tone on pulmonary vascular responses to acetylcholine were investigated in the pulmonary vascular bed of the intact-chest cat. Under conditions of controlled blood flow and constant left atrial pressure, intralobar injections of acetylcholine under low-tone base-line conditions increased lobar arterial pressure in a dose-related manner. When tone was increased moderately by alveolar hypoxia, acetylcholine elicited dose-dependent decreases in lobar arterial pressure, and at the highest dose studied, acetylcholine produced a biphasic response. When tone was raised to a high steady level with the prostaglandin analogue, U46619, acetylcholine elicited marked dose-related decreases in lobar arterial pressure. Atropine blocked both vasoconstrictor responses at low tone and vasodilator responses at high tone, whereas meclofenamate and BW 755C had no effect on responses to acetylcholine at low or high tone. The vasoconstrictor response at low tone was blocked by pirenzepine (20 and 50 micrograms/kg iv) but not gallamine (10 mg/kg iv). The vasodilator response at high tone was not blocked by pirenzepine (50 micrograms/kg iv) or gallamine or pancuronium (10 mg/kg iv). The present data support the concept that pulmonary vascular responses to acetylcholine are tone dependent and suggest that the vasoconstrictor response under low-tone conditions is mediated by a high-affinity muscarinic (M1)-type receptor. These data also suggest that vasodilator responses under high-tone conditions are mediated by muscarinic receptors that are neither M1 nor M2 low-affinity muscarinic-type receptor and that responses to acetylcholine are not dependent on the release of cyclooxygenase or lipoxygenase products.

This paper describes and accounts for the tonal split between bound argument prefixes of Il-Keekonyokie Maa verbs with (apparently) High and Low tone. Data with the tonal split are given, followed by an analysis showing that the apparent High tone must be lexically unspecified for these prefixes. This analysis is required because a lexical High prefix tone in certain verbs would cause downstep, where down step is not observed. Neutralization of the tone split is then considered, with the data presented and accounted for by an analysis for each of the two verb root classes. The conclusion discusses the need for the apparent word initial High tone to be spread from the stem tone.

This paper examines negation and types of tense negation in Urhobo. It also identifies negation marker(s) and the manner in which these negation marker(s) are used in sentences. Transformational generative grammar theory of analysis was used in the work. The aim of this study is to determine the syntactic characteristics of negation in Urhobo. The study shows that negative construction in the Urhobo language involves the doubling of the last vowel of the last word in sentences; or what may be called the lengthening of the last vowel of the lexical item in the sentence. Also, the low-high tone can do the same function as the lexical or grammatical tone. It was observed that negation is a natural phenomenon that cuts across Urhobo, and that the orthographic representation of the low tone, which is the copying of the final vowel, is written contiguously while other negative markers are written separately. It was also observed that Urhobo operates suffixation. Finally, the study work reveals ejo, je, odie and and oyen as negative markers in Urhobo.
