  1. 1. Real-time Sound Analysis to Count Opening Cycles of Automatic Doors

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Teodor Renman; Charlie Ringström; [2023]
    Keywords : Sound analysis; signal processing; event detection; MFCC; real-time; automatic door; embedded programming; stm32; microcontroller; Technology and Engineering;

    Abstract : Counting opening cycles on an automatic sliding door is of great interest for a company manufacturing doors, such as ASSA Abloy. These metrics could be used for consumer statistics or for door diagnostics. Counting opening cycles is seemingly trivial when there is access to the door’s internal diagnostics or having adequate sensors. READ MORE

  3. 2. Instability of a bi-directional TiFGAN in unsupervised speech representation learning

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

    Author : Matthaios Stylianidis; [2021]
    Keywords : ;

    Abstract : A major challenge in the application of machine learning in the speech domain is the unavailability of annotated data. Supervised machine learning techniques are highly dependent on the amount of labelled data and the quality of the labels. READ MORE

  4. 3. Automatic Speech Quality Assessment in Unified Communication : A Case Study

    University essay from Linköpings universitet/Programvara och system

    Author : Kevin Larsson Alm; [2019]
    Keywords : speech; voice; communication; qoe; quality of experience; unified communication; uc; speech quality assessment; speech quality; voice calls; gaussian mixture model; gmm; gaussian mixture regression; gmr; mel frequency cepstrum coefficients; mfcc; human feature cepstrum coefficients; hfcc; gammatone frequency cepstral coefficients; gfcc;

    Abstract : Speech as a medium for communication has always been important in its ability to convey our ideas, personality and emotions. It is therefore not strange that Quality of Experience (QoE) becomes central to any business relying on voice communication. READ MORE
