In a syllable-based speaker-independent Chinese continuous speech recognition system based on classical Hidden Markov Model (HMM), a Bayesian approach of keyword confidence estimation is studied, which utilizes both acoustic layer scores and syllable-based statistical language model (LM) score. The Maximum a posteriori (MAP) confidence measure is proposed, and the forward-backward algorithm calculating the MAP confidence scores is deduced. The performance of the MAP confidence measure is evaluated in keyword spotting application and the experiment results show that the MAP confidence scores provide high discriminability for keyword candidates. Furthermore, the MAP confidence measure can be applied to various speech recognition applications.

全无机CsPbBr_(3)钙钛矿材料因其本征稳定性好、成本低廉从而在光伏领域展现出巨大的应用潜力,但目前CsPbBr_(3)太阳能电池的光电转换效率仍远低于其他体系的钙钛矿太阳能电池.本文以无空穴传输层结构的碳基CsPbBr_(3)全无机钙钛矿电池作为研究对象,以多步旋涂法为基础,通过在PbBr_(2)(DMF)溶液中添加2-苯乙胺溴盐(PEABr)来调控CsPbBr_(3)薄膜的结晶质量,降低薄膜缺陷态密度,钝化晶粒间界,并对其中的关键工艺参数包括CsBr的用量(旋涂次数)、旋涂PbBr_(2)薄膜时的衬底预热温度以及退火温度进行了优化.最终在大气环境下获得了兼具稳定和高效的无空穴传输层结构的碳基CsPbBr_(3)太阳能电池,器件的光电转换效率达到8.25%,并在无封装条件下保存1500 h仍可保持90%以上的效率,对于进一步拓展CsPbBr_(3)钙钛矿电池的优化设计思路具有重要意义.
