Abstract: Abstract: Technological advance of speech recognition facilitates intelligent human-computer interactions. And applications of speech recognition technology have made human communications easier and more instantaneous. Starting with a look at the past and the present of Russian speech recognition, this paper attempts to conduct a detailed analysis on fundamental principles of speech recognition, speech recognition technology based on Hammond theoretical groundwork for consecutive vast-vocabulary speech recognition. The paper also demonstrates steps for establishing models in Russian acoustics and speeches. As to technological barriers in speech recognition, it probes into possible way out strategies. Finally, it predicts future development direction and application prospects for Russian speech recognition technology.

俄语(Русскийязык)[1]是俄罗斯和联合国的官方语言,也是我国少数民族正式语言。在前苏联和俄罗斯使用,俄语在苏联时期具有很重要的地位,直到现在仍然有些独联体国家在广泛使用,虽然这些国家已经开始强调本地语言的重要性,但在这些国家之间依然使用俄语进行交流。全球有超过一亿四千万把俄语作为母语使用,有近四千五百万人以第二语言使用,使用俄语媒体的有3亿多人。我国俄罗斯族使用俄语进行交流,聚集地分布在新疆地区的阿勒泰、伊犁、塔城及内蒙古呼伦贝尔市的额尔古纳、满洲里等地,
语音识别(Speech Recognition)[2]是指在各种情况下,识别出语音的内容,让机器听懂人说的话,根据其信息而执行人的不同意图。它是一门交叉学科,涉及与计算机、语音语言学、通信、信号处理、数理统计、神经心理学人工智能、和神经生理学等学科。……
