  1. 1. Detecting Signal Corruptions in Voice Recordings for Speech Therapy

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Helmer Nylén; [2021]
    Keywords : Noise; Classification algorithms; Audio recording; Machine learning; Acoustic signal processing; Störning; Klassificeringsalgoritmer; Ljudinspelning; Maskininlärning; Akustisk signalbehandling;

    Abstract : When recording voice samples from a patient in speech therapy the quality of the recording may be affected by different signal corruptions, for example background noise or clipping. The equipment and expertise required to identify small disturbances are not always present at smaller clinics. READ MORE

  3. 2. Development of embedded devices for automated acoustic resonance analysis in material quality classification.

    University essay from Uppsala universitet/Signaler och System

    Author : Christopher Selander; [2014]
    Keywords : signals analysis; embedded; devices; resonance frequencies; acoustic; quality; signalbehandling; akustisk; resonansfrekvenser; inbyggda; system; kvalité;

    Abstract : In this report we investigate whether an embedded system can be used to determine materials quality by analysing the acoustic resonance frequencies. Through experiments the necessary specifications are established and suitable circuits constructed. Signal analysis is performed by a FFT-based algorithm. READ MORE

  4. 3. Acoustic signature filtering and tracking on Android platforms

    University essay from Fysik och elektroteknik; Tekniska högskolan

    Author : Viktor Johansson; Daniel Josefsson; [2013]
    Keywords : signalbehandling; signal processing; FFT; STFT; Kalmanfiltrering; Android; aukustisk signatur; acoustic signature; filtering; tracking; målföljning;

    Abstract : Denna rapport omfattar ett arbete kring att förbättra signalbehandling och målföljning av en förbränningsfrekvens i en androidapplikation för effektberäkning hos accelererande fordon. Den ursprungliga applikationen är utvecklad på i3tex AB och det var även där som arbetet utfördes. READ MORE

  5. 4. Akustisk ekoutsläckare

    University essay from Blekinge Tekniska Högskola/Institutionen för signalbehandling

    Author : Jörgen Nordberg; Joakim Skoog; [1996]
    Keywords : akustiska ekovägen; Digital Signal Processor;

    Abstract : This Masters thesis report evaluates a method of acoustic echo cancellation in a hands-free mobile phone system. The method uses an adaptive subband filter architecture to get a faster convergence rate and adaptive FIR filters that are easy to handle. READ MORE
