Adaptiv stämning : En bedömning av acceptabilitet och tonkvalitetsuppfattning

This thesis presents an adaptive tuning system that can be described as a dynamic Just Intonation tuning system, being compatible with equally tempered instruments. The tuning system is called Hermode Tuning (HMT) and the tuning used as comparison for evaluation is the standardized western tuning, the equal tempered tuning. This study investigates preferences for these two musical tuning systems, depending on whether the tunings are presented on a piano or with woodwind instruments. A listening test was done with students at the Falun Conservatory of Music, including both a vertical listening (intervalls) and a horizontal listening (cadenses and musical compositions) of Hermode tuned musical material. Overall the results showed no significant preferences for either tuning system irrespectively of what instrument it was presented with. The clearest results was that of a misjudged just intonated perfect third on the piano and a preference for an adaptively tuned piano presented in a simple harmonic structure, with a parameter setting of HMT 70%. Materials for comparison was partly taken from Hermode´s own website, but overall the attitude towards these sequenses (using a likert scale of one to five) showed a low expected value. This shows the complexity of the topic and no general conclusions regarding the choice of intonation or tuning system could be done for the presented material.

La perception du français oral par des apprenants suédois

Swedish learners of French often experience large difficulties in understanding spoken French. Words that the learners know very well when written or when pronounced separately are often hard to recognize in the speech flow. The aim of this study is to examine Swedish learners’ perception of French speech in order to identify the problems. The thesis consists of two parts. The first part provides an introduction to the perception of a second language. It also describes the phonological structures of Swedish and French and gives an overview of studies of the perception of spoken French. The second part of the thesis contains a presentation and an analysis of four perception experiments conducted with Swedish learners of French. The results show that the learners often confuse phonological contrasts that do not exist in Swedish. It is furthermore found that the phonological processes of schwa deletion, liaison, enchaînement and voicing assimilation contribute to the perception problems. However, although liaison may complicate word recognition the results indicate that the so-called potential liaison does so to an even greater extent. In a listening test using nonsense words, the learners seem actually to expect liaison when perceiving a word that can be linked to a following nonsense word. In fact, sequences like un navas and un avas are both perceived as un avas. Paradoxically, liaison thus seems to be most problematic when it does not occur. As to schwa deletion, the results show that word recognition is delayed when the schwa in the first syllable is deleted, as in la s’maine. In addition, the learners make a large number of errors due to schwa deletion. This phonological process sometimes completely prevents word recognition, especially when combined with a voicing assimilation. Schwa deletion thus seems to strongly complicate Swedish learners’ word recognition in spoken French.

Student's second-language grade may depend on classroom listening position

The purpose of this experiment was to explore whether listening positions (close or distant location from the sound source) in the classroom, and classroom reverberation, influence students' score on a test for second-language (L2) listening comprehension (i.e., comprehension of English in Swedish speaking participants). The listening comprehension test administered was part of a standardized national test of English used in the Swedish school system. A total of 125 high school pupils, 15 years old, participated. Listening position was manipulated within subjects, classroom reverberation between subjects. The results showed that L2 listening comprehension decreased as distance from the sound source increased. The effect of reverberation was qualified by the participants' baseline L2 proficiency. A shorter reverberation was beneficial to participants with high L2 proficiency, while the opposite pattern was found among the participants with low L2 proficiency. The results indicate that listening comprehension scores-and hence students' grade in English-may depend on students' classroom listening position.
