The HMM-based TTS can produce a highly intelligible and decent quality voice. However, sometimes the synthesized speech exhibits perceptibly annoying glitches due to F0 extraction errors in the training data and voiced/unvoiced swapping errors in F0 generation. In the conventional MSD based F0 modeling [10], the dual but incompatible two probabilistic(More)
Learning a second language is hard, especially when the learner's brain must be retrained to identify sounds not present in his or her native language. It also requires regular practice, but many learners struggle to find the time and motivation. Our solution is to break down the challenge of mastering a foreign sound system into minute-long episodes of(More)
Sinus histiocytosis with massive lymphadenopathy (SHML) or Rosai-Dorfman disease (RDD) is an uncommon but well-defined benign self-limited clinicopathological entity. It mainly involves lymph nodes. Extranodal involvement is seen in up to 43% of cases, with the most common location in the head and neck region. Primary RDD occurring in the bone is rare with(More)
Multiple input multiple output (MIMO) systems that use antenna arrays at both the transmitter and receiver are gaining much more attention and efforts in wireless communication research due to their potential to increase considerably capacity in mobile cellular communications. However, in the real propagation environment of cellular communications, it is(More)
Herein, we reported a yellow emission probe 1-methyl-4-(6-morpholino-1, 3-dioxo-1H-benzo[de]isoquinolin-2(3H)-yl) pyridin-1-ium iodide which could specifically stain mitochondria in living immortalized and normal cells. In comparison to the common mitochondria tracker (Mitotracker Deep Red, MTDR), this probe was nontoxic, photostable and ultrahigh(More)
Bidirectional long short-term memory (BLSTM) recurrent neural networks are powerful acoustic models in terms of recognition accuracy. When BLSTM acoustic models are used in decoding, the speech decoder needs to wait until the end of a whole sentence is reached, such that forward-propagation in the backward direction can then be performed. The nature of(More)
Stress-induced viscous flow is the characteristic of atomic movements during plastic deformation of metallic glasses in the absence of substantial temperature increase, which suggests that stress state plays an important role in mechanically induced crystallization in a metallic glass. However, it is poorly understood. Here, we report on the stress-induced(More)
Recently, several fast speaker adaptation methods have been proposed for the hybrid DNN-HMM models based on the so-called discriminative speaker codes (SC) [1-3] and applied to unsupervised speaker adaptation in speech recognition [4]. It has been demonstrated that the SC based methods are quite effective in adapting DNNs even when only a very small amount(More)
Recently, the speaker code based adaptation has been successfully expanded to recurrent neural networks using bidirectional Long Short-Term Memory (BLSTM-RNN) [1]. Experiments on the small-scale TIMIT task have demonstrated that the speaker code based adaptation is also valid for BLSTM-RNN. In this paper, we evaluate this method on large-scale task and(More)
