@inproceedings{11877, abstract = {{This paper describes the improvements in a time synchronous beam search strategy for a 10000-word continuous speech recognition task. The improvements are based on two measures: a tree-organization of the pronunciation lexicon and a novel look-ahead technique at the phoneme level, both of which interact directly with the detailed search at the state levels of the phoneme models. Experimental tests were performed for four speakers on a 12306-word task. As a result of the above measures, the overall search effort was reduced by a factor of 17 without a loss in recognition accuracy.}}, author = {{Ney, Hermann and Haeb-Umbach, Reinhold and Tran, B.

Two different effects were identified: (i) an oscillatory field of frequency corresponding to the separation between the coupled levels in the quantum-well pair (~ 1.5 THz); and (ii) an “instantaneous” electromagnetic field pulse that appears to follow the time evolution of the exciting laser pulse. The oscillatory field is understood to be caused by the coherent oscillation of optically created electrons from one well to the other.[1] The “instantaneous” part we believe is caused by a new mechanism proposed in Ref. 2. The essence of this “instantaneous” mechanism is that electron-hole pairs are created in a biased semiconductor with a net polarization. The density of these pairs follows the light field, as does the induced polarization, hence, generating an electromagnetic source that follows the light pulse. Such mechanisms have been discussed before for photon energies below the optical bandgap energy,[3] although they have so far been difficult to observe. In our work, we have generalized and extended such effects to photon energies above the handgap energy. In this paper we will discuss both of these mechanisms as well as the fourwave-mixing (FWM) signal,[4] and show how they can be understood within one unified formalism. We will also show that the calculations agree well with the experimental results.}}, author = {{Meier, Torsten and Schulze, A. and Scmittrink, S. and Thomas, P. and Chuang, S.L.}}, booktitle = {{International Quantum Electronics Conference}}, location = {{Vienna, Austria}}, title = {{{Terahertz Electromagnetic Pulse Generation and Four-Wave Mixing in Coupled Quantum Wells}}}, year = {{1992}}, }
