  4. 28. Achieving Automatic Speech Recognition for Swedish using the Kaldi toolkit

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Zimon Mossberg; [2016]
    Keywords : ASR; Kaldi; NST; GMM-HMM;

    Abstract : The meager offering of online commercial Swedish Automatic Speech Recognition ser-vices prompts the effort to develop a speech recognizer for Swedish using the open sourcetoolkit Kaldi and publicly available NST speech corpus. Using a previous Kaldi recipeseveral GMM-HMM models are trained and evaluated against commercial options toallow for reasoning of the performance of a customized solution for Automatic SpeechRecognition to that of commercial services.

  5. 29. Speech Recognition System for Noisy Environment

    University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Author : Hongzhe Li; [2015]
    Keywords : speech recognition; multilayer perceptron; spectral subtraction;

    Abstract : With the development of big data computing, the speech recognition has been popular for serving human’s life. However, when place the speech recognition system into noisy environments, the background noises greatly degrades the speech recognition system accuracy as it adds in unuseful information into the desired speech.

  6. 30. A critical examination of deep learningapproaches to automated speech recognition

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : NIZAR GANDY ASSAF LAYOUSS; [2014]
    Keywords : ;

    Abstract : Recently, deep learning techniques have been successfully applied to automatic speech recognition (ASR) tasks. Most current speech recognition systems use Hidden Markov Models (HMMs) to deal with the temporal variability of speech and Gaussian mixture models (GMMs) are exploited to model the emission probability of the HMM.
