It is shown that the inclusion of the NN model between the acoustic processor and the HMM improves the recognition and avoids the clustering and labelling phases.Arriola, Y.Carrasco, R.A.Institute of Electric and Electronic EngineerTelecommunications Symposium, 1990. ITS '90: SBT/IEEE ...
“传统”方式的声学模型一般采用隐马尔可夫模型(HMM),而“端到端”方式一般采用深度神经网络(DNN) Kaldi架构如所示,最上面是外部的工具,包括用于线性代数库BLAS/LAPACK和我们前面介绍过的OpenFst。中间是Kaldi的库,包括HMM和GMM等代码,下面是编译出来的可执行程序,最下面则是一下脚本,用于实现语音识别的不同步骤(比如...
This new paremeter models the acoustic HMM's temporal evolution. Using the expanded set of HMMs for speech recognition a significant improvement in performance is achieved. Next, we will use this new architecture for utterance verification in a second opinion framework. We will consign to the ...

Hidden Markov models (HMM) and dynamic time warping (DTW) are two such examples of traditional statistical techniques for performing speech recognition. Using a set of transcribed audio samples, an HMM is trained to predict word sequences by varying the model parameters to maximize the likelihood ...
Speech segmentation is a crucial step in automatic speech recognition because additional speech analyses are performed for each framed speech segment. Conventional segmentation techniques primarily segment speech using a fixed frame size for computational simplicity. However, this approach is insufficient for...
