连续语流中声学地标的检测与分割

在语音识别系统中,针对汉语普通话语音特点,增加采用分层级多参数加权综合的检测方法,以感知线索为依据,对连续语音流中的辅音性、阻塞性、擦音性、送气性、响音性、延续性、鼻音性、元音性、后位性等区别特征和语音特征的声学地标进行检测和分割。算法充分考虑了不同说话人、语音语境、语速和说话风格对声学地标的影响,这有助于提高检测和分割的准确率和鲁棒性。

Motor adaptation in complex sports – The influence of visual context information on the adaptation of the three-point shot to altered task demands in expert basketball players

Abstract

We examined the influence of visual context information on skilled motor behaviour and motor adaptation in basketball. The rules of basketball in Europe have recently changed, such that that the distance for three-point shots increased from 6.25 m to 6.75 m. As such, we tested the extent to which basketball experts can adapt to the longer distance when a) only the unfamiliar, new three-point line was provided as floor markings (NL group), or b) the familiar, old three-point line was provided in addition to the new floor markings (OL group). In the present study 20 expert basketball players performed 40 three-point shots from 6.25 m and 40 shots from 6.75 m. We assessed the percentage of hits and analysed the landing position of the ball. Results showed better adaptation of throwing performance to the longer distance when the old three-point line was provided as a visual landmark, compared to when only the new three-point line was provided. We hypothesise that the three-point line delivered relevant information needed to successfully adapt to the greater distance in the OL group, whereas it disturbed performance and ability to adapt in the NL group. The importance of visual landmarks on motor adaptation in basketball throwing is discussed relative to the influence of other information sources (i.e. angle of elevation relative to the basket) and sport practice.     

民众对城市地标感知和认可的实证研究——以广东省惠州市为例

从民众感知和认可的角度以惠州市为例对城市地标的塑造进行实证研究。通过发放470份问卷,在可信度分析的基础上,运用多重响应分析方法和交叉分析方法对数据进行分析,总结出城市地标塑造的民众感知与认可标准,即满足民众文化需求且融入民众生活。因此,关注内涵比关注类型更重要。
