Two hypotheses have been proposed in order to account for velar softening, i.e., a process through which /k/ changes to an affricate. Whereas one hypothesis states that for the process to apply the velar stop has to be realized as an (alveolo) palatal stop (articulation-based hypothesis), the other claims that velar softening is triggered by acoustic similarity between the input and output segments (acoustic equivalence hypothesis). The present paper investigates the acoustic equivalence hypothesis by comparing several acoustic properties of /k/ in various vowel contexts with those of /ts , ts , tc / for three languages differing in stop burst aspiration, i.e., German, Polish and Catalan. Results suggest that the acoustic equivalence hypothesis could account for velar softening in aspirated velar stops but not in unaspirated velar stops. The results also provide an explanation as to why aspirated velar stops are prone to undergo softening more easily when followed by front vocalic segments than in other contexts and positions
This paper shows that several typologically unrelated languages share the tendency to avoid voiced sibilant affricates. This tendency is explained by appealing to the phonetic properties of the sounds, and in particular to their aerodynamic characteristics. On the basis of experimental evidence it is shown that conflicting air pressure requirements for maintaining voicing and frication are responsible for the avoidance of voiced affricates. In particular, the air pressure released from the stop phase of the affricate is too high to maintain voicing, which in consequence leads to a devoicing of the frication part.
A model is proposed that interprets a variety of connected speech processes as resulting from prosodic modulations at different tiers of functional speech motor control along the hypo-hyper dimension [10]. The general background of the model is given by the trichotomy of A-, B- and C-prosodic phenomena [15] that together constitute the acoustic makeup of any speech utterance (with regard to their respective time domains at the uttarance/phrase level, the syllabic level and the segmental level).
Bilabial stops undergoing Surface Palatalization (SP) were analyzed in an EMMA/EPG study. Articulatorily, the point of maximal palatal contact and the labial opening movement were analyzed. The acoustic analysis pertained to stop related timing and the point of the highest F2-value. Results show (i) that SP yields a higher F2 at vowel onset and a lengthened opening gesture and (ii) that morphemeinduced palatalizations are distinguished from word initial ones and sandhi-palatalizations articulatorily and acoustically by a shorter delay of palatal target position with respect to stop production; (iii) no differences are found between ‘repalatalized’ and plain segments in case of sandhi palatalization.
Coherence in hypertext
(1999)
At first sight hypertext does not look !ike a good subject for research on coherence. Hypertext is non-linear text, and coherence is typically defined for linear text. So coherence does not seem to be involved in hypertext at all. But on closer inspection it emerges that some of the basic structural problems with hypertexts are classical problems of coherence.
Our study is concerned with the identification of ‘difficult’ structure s in the acquisition of a foreign language, which will shed light on theoretical considerations of L2 processing. We argue that – compared to simple vocabulary items or abstract syntactic patterns – structures that contain lexical material as well as categorial variables are especially difficult to acquire. The difficulty level for particular patterns is shown to depend on surface invariability but not on the syntactic categories within which target patterns are embedded. As an example we study the distribution of certain structures which are underused by L2 German learners.
Word formation in Distributed Morphology (see Arad 2005, Marantz 2001, Embick 2008): 1. Language has atomic, non-decomposable, elements = roots. 2. Roots combine with the functional vocabulary and build larger elements. 3. Roots are category neutral. They are then categorized by combining with category defining functional heads.
This article discusses the divergent status of the two particles lé and lá in the grammar of Konkomba, a Gur language (Niger-Congo) of the Gurma subgroup. While previous studies claim that both particles are focus markers, this author argues that only the particle lá should be analyzed as a pure pragmatic device. Distributional studies suggest that the use of particle lé, on the other hand, is only required under specific focus conditions, and primarily represents a syntactic device.
