This bachelor thesis is a literature study of the possibility to analyze and modify speech signals and will act as a pilotstudy for future theses in speaker verification.The thesis deals with the voice anatomy and physiology, synthesizer history and the various methods available when thevoice is used as a biometric method.A search and evaluation of existing programs have been conducted to determine the relevance of the attacks on theparameters used for speaker verification.

Syftet med denna uppsats är att genom textanalys av fem läroböcker i skolämnet svenska visa vilka lärstilar, ur ett perceptuellt perspektiv, som främst gynnas i böckernas övningar. Vår undersökning är därmed utförd med tre kategorier av lärstilar: auditiv, kinestetisk och visuell. Den är främst av kvantitativ karaktär men har även kvalitativa inslag.     Resultatet visar att lärstilarna inte varieras särskilt mycket i de analyserade läromedlen, dessutom finns det en avgörande mängd övningar anpassade för den visuella lärstilen i majoriteten av böckerna. De slutsatser vi kunnat dra är att det är den visuella lärstilen som framförallt gynnas, varpå de övriga två hamnar i skymundan. Det kan också konstateras att fyra av de fem analyserade läroböckerna har ett relativt liknande innehåll och upplägg..

Vad kännetecknar en bra röst? Denna studie syftar till att utröna huruvida det finns något i den akustiska talsignalen som kan säga något om vilken uppfattning lyssnaren bildar sig om talaren. I kommersiella sammanhang är sättet att förmedla viktigt för att ge lyssnaren rätt budskap och i detta är rösten ett viktigt redskap. Grunden till föreliggande studie var att låta en grupp lyssnare bedöma några olika röster samt att analysera rösterna akustiskt, varefter en jämförelse mellan resultat från lyssnarbedömning och akustisk analys gjordes.En kvinna och en man i grupperna professionella samt icke-professionella röstanvändare läste in en standardtext. Inspelningarna analyserades akustiskt och bedömdes perceptuellt av en lyssnargrupp, omfattande 10 individer utan röstprofessionell kompetens.

Nano materials can today be found in a wide range of consumer products and the number of new products on the market is expected to inrease. In the shadow of hope for nano materilas potential in various applications, low awareness of its health and environmental risks is hiding. Furthermore, the knowledge about people´s risk perception of nano materials is limited. Parallel to the situation described above, the scholls meet the challenge of incrasing the scientific literacy. To achieve this goal, skills in argumentation in science studies has been emphasized and the concept of socio-scientific issues has been emerged.

Literature and studies exist on how to create services in the best interest of the client or how these services have an impact on individuals. They are however mainly from a social work professional stand point and rarely from how clients would develop and create the services that can imply a life change for them. Especially when working with children under 18 years old issues of agency and age that can result in the disregard of the Convention on the Right of the Child (UNCRC). The target group of this study is therefore youth between the ages of 15 to 17 years old in three cities across Sweden to allow them to voice their opinion and experience of being in treatment. Resulting from that is the aim of this study ? to investigate how an intensive treatment method like Multisystemic Therapy is described from a client?s point of view.

Information about the risks involved shall be distributed to the people living in the area nearby to potentially dangerous installation. Swedish law stipulates strict requirements on what information should be supplied, but the law itself does not give any guidance on presentation. The main purpose of the study is to give recommendations on how to improve the information brochures. Within the study, eight people working with risk information have been interviewed and seven different risk information brochures have been studied. Also, a theoretical analysis and a practical experiment were performed using brochures from two municipalities.

A pilot study conducted on four patients, which we received from the Sahlgrenska University Hospital, who were all potential candidates for a cochlear implant. We fitted our test subjects with a pair of frequency compressing hearing aids called Phonak Naida V SP during the study and let them evaluate them for about seven weeks. Measurements made with monosyllabic words throughout the study showed significant differences in speech perception (p?0.05) compared to their regular hearing aids in 3 out of 4 cases. De-activation of the frequency transposed function showed significant decreases in 3 out of 4 cases compared to when it was activated.All test subjects were satisfied with the new hearing aids and chose to keep using them at the end of the study..

The purpose of this essay is to examine how librarians perceive library plans, if they are important for their work and if so, in what ways. In order to analyze this, I have used a phenomenographic approach. My goal, by using this method, is to uncover perceptions and variations among these. The research questions are: What variations of perception of library plans exist among librarians? To what extent can the varied perceptions of library plans be linked to librarians' work? What does the variation of perception say, in relation to the expectations expressed in international and national documents, about library plans? The material used in a phenomenographic analysis consists of interviews.

This bachelor thesis aims to explore the public?s personal connection and attachment to place, as well as their perception of changes in the built environment that has occurred in close proximity to the area. Based upon a questionnaire carried out in a public square in Gothenburg, namely J?rntorget, the study examines the impact of the construction of two high-rise buildings that was initiated roughly five years ago adjacent to the square. The essays theoretical framework is based on the concept sense of place, a concept which derives from the discipline of Geography. Sense of place encompasses the relationship between people and spatial settings, which includes e.g.

In outdoor education the empirical outdoor experience is an important basis for a learning process ? the teacher can affect learning with the choice of location. In order to develop the model in school, we need to build on teachers' perception of how their every day schoolwork looks like. This paper takes as its starting point at three teachers' perception of their learning environment and outdoor environments as well as a theoretical model of the site's importance in the learning process. The paper addresses both the importance of a structured and a unstructured meeting with outdoor sites.

The aim of the study has been to see if there are cultural differences in the perception of health and, if so, analyze if this is something needed to be taken in consideration in Swedish healthcare, schools and so forth.The participants were children aged between nine and nineteen. The study was performed at Islamic center's Islamic free school in Rosengård, Malmö. We have used a phenomenological approach that encourages the participants to talk freely and in their own words about a given subject, in our case, health. To analyze the transcribed interviews we have used software, Minerva, an application of Meaning Constitution Analysis (MCA) developed by Roger Sages, lector at The University of Lund.The results show that all the participants, regardless of culture, feel that eating right and exercising are crucial for their health. Additional to this we have found that the participants have a very strong solidarity whit their family and their origin country.

BakgrundKraven på evidensbaserad vård ökar ständigt. Att jämföra patienters självskattade besvär före och efter behandling är ett sätt att utvärdera behandlingseffekten.  Rösthandikappindex (RHI) och VA-skala för röstbesvär är två verktyg för utvärdering av röstbehandling. Tidigare studier har visat att röstbehandling ger minskade självskattade röstbesvär.SyfteSyftet med denna studie var att med självskattningsformulär utvärdera effekten av logopedisk röstbehandling i Västerbottens läns landsting (VLL) och undersöka om behandlingseffekten påverkas av kön, diagnos, antal behandlingstillfällen och hur mycket tid patienten är beredd att lägga på behandling, samt att undersöka om det finns ett samband mellan självskattningsformuläret RHI och VA-skala för röstbesvär.Metod102 patienter, 28 män och 74 kvinnor, som under perioden januari 2009 till september 2012 genomgått logopedisk röstbehandling inom VLL, deltog i studien. Deltagarna rekryterades retrospektivt.

Det förekommer mycket forskning kring brytning hos andraspråksinlärare. Många studier använder sig av modersmålstalare som har skattat brytning hos andraspråksinlärare på en Likert-skala (Jesney, 2004). Ett mål med föreliggande studie var att bidra till en ökad insikt om och hur personer med svenska som andraspråk uppfattar utländsk brytning i svenska på samma sätt som en modersmålstalare gör och om det fanns något samband mellan förmågan att uppfatta brytning och förmågan att utrycka sig på svenska.  Djupare analyser gjordes av perception och produktion hos andraspråksinlärare. Designen på studien bestod av tre grupper och omfattade 42 deltagare som representerade 15 språk . Två av grupperna innehöll andraspråksinlärare och den tredje gruppen bestod av modersmålstalare.
