Hybrid Techniques based Speech Recognition
Information processing has an important application which is speech recognition. In this paper, a two hybrid techniques have been presented. The first one is a 3-level hybrid of Stationary Wavelet Transform (S) and Discrete Wavelet Transform (W) and the second one is a 3-level hybrid of Discrete Wavelet Transform (W) and Multi-wavelet Transforms (M). To choose the best 3-level hybrid in each te...
متن کاملImproving of Feature Selection in Speech Emotion Recognition Based-on Hybrid Evolutionary Algorithms
One of the important issues in speech emotion recognizing is selecting of appropriate feature sets in order to improve the detection rate and classification accuracy. In last studies researchers tried to select the appropriate features for classification by using the selecting and reducing the space of features methods, such as the Fisher and PCA. In this research, a hybrid evolutionary algorit...
متن کاملHybrid NN/HMM acoustic modeling techniques for distributed speech recognition
Distributed speech recognition (DSR) where the recognizer is split up into two parts and connected via a transmission channel offers new perspectives for improving the speech recognition performance in mobile environments. In this work, we present the integration of hybrid acoustic models using tied posteriors in a distributed environment. A comparison with standard Gaussian models is performed...
متن کاملDistributed speech recognition using traditional and hybrid modeling techniques
We compare the performance of different acoustic modeling techniques on the task of distributed speech recognition (DSR). The DSR technology is interesting for speech recognition tasks in mobile environments, where features are sent from a thin client to a server where the actual recognition is performed. The evaluation is done on the TI digits database which consists of single digits and digit...
متن کاملApproaches to Speech Recognition based on Speaker Recognition Techniques
We have experimented with approaches to speech recognition that are inspired by work from the speaker recognition community, including an approach that was used in IBM’s best speech recognition submissions in its January 2009 evaluation. Here we explain in general terms the techniques used, without the full technical details. We initially used an approach based on Maximum a Posteriori (MAP) ada...
