  1. 1. Decoding communication of non-human species - Unsupervised machine learning to infer syntactical and temporal patterns in fruit-bats vocalizations.

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Luigi Assom; [2023]
    Nyckelord :animal decision making; unsupervised machine learning; UMAP; autoencoders; classifiers; bioacoustics; combinatory syntax; animal communication;

    Sammanfattning : Decoding non-human species communication offers a unique chance to explore alternative intelligence forms using machine learning. This master thesis focuses on discreteness and grammar, two of five linguistic areas machine learning can support, and tackles inferring syntax and temporal structures from bioacoustics data annotated with animal behavior.

  3. 2. SIGNALBEHANDLING MED AVANCERAD BLUETOOTH-TEKNIK OCH OPTIMERADE OPERATIVSYSTEM : Optimera audiosystemet i ett avancerat inbyggt system med en fler-trådad programvara och synkroniserings mekanism

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Omar Ibrahim; [2023]
    Nyckelord :BM83 bluetooth; audio subsystem; Inter-IC sound; Digital Signal Processor; Operative System; DSP platform tests.;

    Sammanfattning : This study is about replacing an old bluetooth module with a new variant, namely the BM83 which is an integrated circuit that contains an internal DSP circuit, profiles and important functions such as noise reduction, acoustic echo removal and EQ filtering. The purpose of this study is to replace the old module with the BM83, as well as explore the internal DSP circuit in the BM83. LÄS MER

  4. 3. Undervattenskommunikation : En turboutjämnares förmåga att skatta kanalen

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Marcus Hellström; [2023]
    Nyckelord :undervattenskommunikation; turboutjämning;

    Sammanfattning : Despite advancements in wireless communication worldwide, wireless underwater communication remains a significant challenge. The marine environment presents unique and challenging conditions for wireless communication, rendering radio waves unsuitable for long-distance underwater communication due to the water's absorption of electromagnetic waves.

  5. 4. Evaluating forest restoration effects on timing of avian dawn chorus in Ranomafana National Park, Madagascar

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Marjolein Pijper; [2023]
    Nyckelord :acoustic monitoring; forest restoration; dawn chorus; avian singing; bird monitoring; automatic recognition;

    Sammanfattning : Monitoring of forest restoration efforts is essential to ensure healthy, self-sustaining tropical rainforests. Passive acoustic monitoring is used to monitor vocal activity of birds, which play a key role in forest ecosystems as seed dispersers. LÄS MER

  7. 5. Emotional Prosody in Adverse Acoustic Conditions : Investigating effects of emotional prosody and noise-vocoding on speech perception and emotion recognition

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Cecilia Ivarsson; [2022]
    Nyckelord :Speech perception; Emotional prosody; Emotion recognition; Noise-vocoding; Working memory capacity;

    Sammanfattning : Speech perception is a fundamental function of successful vocal communication, and through prosody, we can communicate different emotions. The ability to recognize emotions is important in social interaction. Emotional prosody facilitates emotion recognition in vocal communication. LÄS MER
