本申请实施例提供了一种基于人工智能的通信方法。
参照图2,图2为本申请基于人工智能的通信方法第一实施例的流程示意图。
本实施例中,所述基于人工智能的通信方法包括以下步骤:
步骤S10,在接收到第一语音信息时,对所述第一语音信息进行语音识别,获得第一语音文本;
本实施例中的基于人工智能的通信方法是由基于人工智能的通信设备实现的,该通信设备可以是个人计算机(personal computer,PC)、笔记本电脑、移动终端(如平板电脑、掌上电脑、手机)等。本实施例中该通信设备以手机为例进行说明;该手机中预先安装有若干社交应用(如即时通讯应用),该手机的用户为一正常人,可称为正常用户;当需要通过该社交应用与某一聋哑用户进行交流时,可以启动该手机中的社交应用,并通过语音的方式进行录入自己的第一语音信息。而对与聋哑用户而言,若将该第一语音信息发送至聋哑用户所用的智能终端(如手机),由于聋哑用户的听力缺陷,可能会出现无法获知该第一语音信息的真实含义;对此,正常用户的手机在接收到该语音信息时,可对该语音信息进行转换,将其转换为对应的手语视频,再将该手语视频发送至聋哑用户的智能终端。 具体的,手机在接收到该第一语音信息时,首先会对该第一语音信息进行分析和识别,提取该语音信息中的语音特征,并根据该语音特征在预设语音库中进行特征查找和匹配,获取到对应的语音文本,并根据该语音文本获取对应的第一文本信息。其中,对第一语音信息的识别和第一文本信息的生成过程,可以是通过预先建立的语音识别模型实现,也即先收集一定数量的语音样本和这些语音样本对应的文本样本,并建立初始语音识别模型,然后通过这些语音样本和文本样本对初始语音识别模型进行迭代训练,不断调整模型参数,直至得到最优模型参数(或是满足预设次数的迭代训练次数、或是识别正确率达到一定阈值),从而根据该最优模型参数得到训练好的语音识别模型。当然,在实际中,对于该语音信息向文本信息的转换过程,也可以是通过第三方提供的API接口(Application Programming Interface,应用程序编程接口)、SDK(Software Development Kit,软件开发工具包)等实现的,例如手机在获取到第一语音信息时,可以调用第三方提供的API接口或SDK,并通过该API接口或SDK调用对应应用程序或工具包对第一语音信息进行语音识别,获得对应的第一语音文本。
步骤S20,通过预设文本校正模型对所述第一语音文本进行文本校正,得到校正文本;
本实施例中,考虑到部分用户由于口语习惯的原因,可能会出现第一语音信息的语句构成与标准语句不完全匹配的情况(句子不通顺),而在语音信息转化为文本信息的过程中,也可能会出现误匹配、误转化,进而导致出现错别字的情况;这些情况会对手语视频的转换准确度造成不利的影响,甚至可能会出现无法识别和转换的情况。对此,本实施例的手机得到在对第一语音文本时,将通过一预设的文本校正模型对该第一语音文本进行文本校正处理,以得到符合一定语法规则(或通用语言习惯)的校正文本,再对该校正文本进行手语转换处理。
具体的,通过预设文本校正模型对第一语音文本进行文本校正,得到校正文本的的步骤包括:
基于预设中文分词规则对第一语音文本的原始语句进行词划分,得到对应的语句词序列;
在文本校正过程中,首先需要根据预设中文分词规则对第一语音文本中的原始语句进行词划分,也将一个连续的句子划分成若干个单独的词,这些若干个单独词由于是按照一定的顺序排序,也即划分后得到的是一个语句词序列。在该语句词序列中需要纠正处理的词可称为目标词,当然在实际中该目标词可能具有多个。而对于该预设中文分词规则,可以基于字符串匹配的方式设置,也即预先存储一词典,该词典中包括有若干标准字符串,然后通过标准字符串匹配的方式进行分词;该预设中文分词规则还可以是基于统计分词的 方式设置,也即在收集大量分词样本的基础上,通过统计类机器学习模型学习词语切分的规律(即训练),得到分词模型,再用该分词模型进行分词。当然,还可以是接入第三方的分词工具进行分词(如SnowNLP、THULAC、jieba分词等)。
获取所述语句词序列中的目标词对应的混淆词,并通过所述混淆词替换所述语句词序列中的目标词,得到候选序列;
在得到语句词序列时,将确定该语句词序列中的目标词,并获取目标词的混淆词。其中,该混淆词可包括一些发音相似的汉字,如汉语同音字(“字”和“自”)、鼻音(“藏”)和非鼻音(“赞”)、卷舌(“找”和非卷舌“早”等;还可包括形似的汉字,例如汉字的同一字根(“固”和“回”)和类似的五笔输入法(“丏”和“丐”);此外,还可包括其它类型(如基于统计)的汉字(如“妻”和“西”、“嫂”和“搜”等)。值得说明的是,对于某个目标词的混淆词,可能具有两个以上(此处“以上”包括本数,下同),也即得到可以混淆集。在得到该目标词的混淆词时,会通过混淆词替换语句词序列中的目标词,得到候选序列;例如,原始语句的语句词序列为(李某/的/是/的确/是/一个/问题),目标词为左起的第一个“是”,对应的混淆词为“事”,则对应的候选序列为(李某/的/事/的确/是/一个/问题)。当然,若混淆词有两个以上,则对应的候选序列也为两个以上。
基于预设文法语言模型分别计算所述语句词序列和所述候选序列的文法得分,并根据所述文法得分在所述语句词序列和候选序列中确定校正序列;
在得到语句词序列和候选序列时,即可根据预设文法语言模型分别计算语句词序列和候选序列的文法得分;该文法得分可认为是该序列所对应的语句在整个中文语言中的出现概率,文法得分越高,其出现概率越大。对于该预设文法语言模型,基于N-Gram汉语语言模型的思想,可以为二元(假设一个词的出现概率只取决于其前面的一个单词)或三元(假设一个词的概率取决于其前面的两个词)文法语言模型,该模型结合了马尔科夫假设、最大似然估计和条件概率进行设置。
具体的,该模型中包括有预设语料库;该预设预料库中包括有预先收集的若干样本语句,还包括有根据这些样本语句所统计的单词出现次数表、以及多元词相邻次数表;其中单词出现次数表记录有预设语料库中各样本语句的每个词在整个预设预料库中的出现次数,如下表1所示:
表1 单词出现次数表
| 词 | 单词出现次数 |
| 我 | 1215 |
| 的 | 3437 |
| 事 | 938 |
| ... | ... |
| 总计 | 13738 |
而多元词相邻次数表,则记录有多个词在整个预设预料库中的出现次数,例如对于二元词相邻次数表,则记录有两个词以一定顺序相邻出现的次数,如下表2所示:
表2 二元词出现的次数
| 我 | 的 | 事 | ... | |
| 我 | 8 | 786 | 3 | ... |
| 的 | 20 | 0 | 988 | ... |
| 事 | 121 | 56 | 228 | ... |
| ... | ... | ... | ... | ... |
对于上述表2,各数值所表示的是(行,列)顺序的单词相邻出现的此时,例如对于上述第二行第三列的数值“786”,所表示的是“我”和“的”两个词以“我/的”形式在预设预料库中出现次数为786次。对于三元词相邻次数表,则记录有三个词以一定顺序相邻出现的次数,以此类推。
在计算语句词序列和候选序列的文法得分时,首先分别需要统计语句词序列和候选序列中各单词在预设语料库中的单词出现次数;对于该单词出现次数的统计,可根据各序列所包括的单词在预设预料库中的单词出现次数表查询得到。其次,还将统计语句词序列中各单词与前位历史词在语料库中的语句词相邻次数,以及候选序列中各单词与前位历史词在预设语料库中的候选词相邻次数;值得说明的是,对于不同的文法语义模型,所需要统计的相邻词的词数可能不同;例如,对于语句词序列(李某/的/是/的确/是/一个/问题),当预设文法语言模型为三元文法语言模型时,所统计的是二元词相邻次数,即需要统计“李某/的”、“的/是”、“是/的确”、“的确/是”、“是/一个”、“一个/问题”的语句词相邻次数;而当预设文法语言模型为三元文法语言模型时,所统计的包括二元词相邻次数和三元词相邻此时,即需要统计“李某/的”、“李某/的/是”、“的/是/的确”、“是/的确/是”、“的确/是/一个”、“是/一个/问题”的语句词相邻次数;以此类推。在得到各单词出现次数、语句词相邻次数和候选词相邻次数时,即可分别计算各序列的文法得分;在计算时,即将语句词序列对应的单词出现次数和语句词相邻次数代入至预设得分公式计算语句词序列的文法得分,并将候选 序列对应的单词出现次数和候选词相邻次数代入预设得分公式计算所述候选序列的文法得分。
可选地,当预设文法语言模型为二元文法语言模型,该预设得分公式为:
其中,P为语句词序列或候选序列的文法得分;
k1为第一预设得分系数,k1>0;
m为语句词序列或候选序列的单词数,m≥2;
C
0为预设语料库中的单词总数,C
0>0;
C(w
1)为语句词序列或候选序列中第1位单词在预设语料库中的单词出现次数;
C(w
i-1)为语句词序列或候选序列中第i-1位单词在预设语料库中的单词出现次数,2≤i≤m;
C(w
i-1,w
i)为语句词序列中第i位单词与前一位历史词在预设语料库中的语句词相邻次数,或为候选序列中第i位单词与前一位历史词在预设语料库中的候选词相邻次数。
可选地,当预设文法语言模型为三元文法语言模型,该预设得分公式为:
其中,P为语句词序列或候选序列的文法得分;
k2为第二预设得分系数,k2>0;
m为语句词序列或候选序列的单词数,m≥3;
C
0为预设语料库中的单词总数,C
0>0;
C(w
1)为语句词序列或候选序列中第1位单词在预设语料库中的单词出现次数;
C(w
1,w
2)为语句词序列中第1位单词与第2位单词在预设语料库中的语句词相邻次数,或为候选序列中第1位单词与第2位单词在预设语料库中的候选词相邻次数;
C(w
i-2,w
i-1)为语句词序列中第i位单词的前一位历史词与前二位历史词在预设语料库中的语句词相邻次数,或为候选序列中第i位单词的前一位历史词与前二位历史词在预设语料库中的候选词相邻次数;
C(w
i-2,w
i-1,w
i)为语句词序列中第i位单词与前一位历史词、前二位历史词在预设语料库中的语句词相邻次数,或为候选序列中第i位单词与前一位历史词、前二位历史词在预设语料库中的候选词相邻次数。
在计算得到语句词序列和候选序列的文法得分时,该文法得分可认为是该序列所对应 的语句在整个中文语言中的出现概率,文法得分越高,其出现概率越大,因此可将文法得分最高的序列所对应的序列作为校正序列。当然,在实际中,可能是语句词序列即为校正序列,也可能是候选序列为校正序列。在确定校正序列时,即可根据该校正序列获得对应的校正文本。
步骤S30,根据所述校正文本在预设手语库中查询对应的手语样本帧,并将所述手语样本帧封装为对应的手语视频;
本实施例中,在得到校正文本时,即可根据该校正文本进行手语视频的转换。具体的,手机可对该校正文本进行语义识别,确定该校正文本的文本语义;当然该文本语义可能是以多段的方式记录的。在得到各段文本语义时,服务器将根据该文本语义在预设手语库中查找与之对应的手语样本帧,然后将各段手语样本帧进行拼接和封装,得到对应的手语视频;其中对于该预设手语库,预先存储有若干语义对应的标准手语样本视频,这些手语样本视频可以是预先录制并存储的。对于该预设手语库,可以是存储在社交应用的服务器或数据库,由手机根据校正文本在服务器中查询得到,从而节约手机的存储空间;当然该预设手语库也可以是存储在手机本地,以方便离线使用。而对于封装的手语视频,则可以根据实际情况(如手机播放器的支持格式或网络条件)选择不同的视频格式(如mp4、mkv、flv等)和清晰度(如480P、720P等)等。
步骤S40,将所述手语视频发送至对应的智能终端,或播放所述手语视频。
本实施例中,手机根据校正文本得到对应的手语视频时,即可将该手语视频发送至聋哑用户所用的智能终端(如手机),以使得聋哑用户通过该智能终端看到该手语视频,并获知正常用户所表达的含义。当然,手机在得到该手语视频时,也可以是直接播放该手语视频,以供正常用户查看,并根据正常用户的操作对该手语视频执行发送、存储或是删除操作。
进一步的,本实施例中的语音信息转化手语视频,是以“正常用户要向聋哑用户发送语音消息前进行转换”为例进行说明;而在实际中,还可以是正常用户通过手机直接向聋哑用户的智能终端发送语音信息,当聋哑用户的智能终端接收到该语音信息时,可根据聋哑用户的操作将该语音信息转化为手语视频,其过程与上述实施例的各步骤类似,此处不再赘述,此时,聋哑用户的智能终端也可认为是本实施例中的基于人工智能的通信设备。
再进一步的,本实施例中的语音信息转化为手语视频的过程中,是先将语音信息转化为文本信息;而若正常用户是直接以文本录入的方式录入文本信息,则手机也可直接对该文本进行校正处理,并进一步对校正后的文本执行手语视频的转化,其过程与上述类似,此处不再赘述。
值得说明的是,本实施例中的语音信息向手语视频转化功能,可以是社交应用中的某个功能,也可以是以API接口或SDK的方式集成在手机等终端中,以供终端中的应用进行调用。
本实施例中,在接收到第一语音信息时,对所述第一语音信息进行语音识别,获得对应的第一语音文本;通过预设文本校正模型对所述第一语音文本进行文本校正,得到校正文本;根据所述校正文本在预设手语库中查询对应的手语样本帧,并将所述手语样本帧封装为对应的手语视频;将所述手语视频发送至对应的智能终端,或播放所述手语视频。通过以上方式,本实施例通过人工智能的方式实现语音向手语的转换,使得聋哑用户也可获知正常用户以语音方式在社交应用发送的信息,为聋哑用户提供了方便,提高聋哑用户的使用体验;其次,在语音转化过程中,还将对语音信息对应的语音文本进行校正处理,以得到符合一定语法规则(或通用语言习惯)的校正文本,再对该校正文本进行手语转换处理,从而避免语句不通顺、错别字等情况对手语视频的转换准确度造成不利的影响,有利于聋哑用户获知语音信息的正确含义。
基于图2所示实施例,提出本申请基于人工智能的通信方法第二实施例。本实施例中,所述基于人工智能的通信方法包括以下步骤:
步骤S50,在接收到手语视频时,基于预设特征提取算法对所述手语视频的各视频帧进行特征提取,获得所述各视频帧的手语特征;
目前,由于聋哑人语音方面具有一定的缺陷,因此通常是以手语与外界进行沟通,在这种情况下聋哑人往往无法直接使用社交应用的语音功能,但对正常人而言在不经过系统学习的情况下也无法获取聋哑人的手语所要表达的含义,这就为双方带来了不便。对此,本实施例中提出一种基于人工智能的通信方法,通过人工智能的方式实现手语视频向语音/文本进行转换,使得正常人利用该方法也可通过社交应用与聋哑人进行沟通,为双方提供了方便。
本实施例中的基于人工智能的通信方法是由基于人工智能的通信设备实现的,该通信设备可以是个人计算机(personal computer,PC)、笔记本电脑、移动终端(如平板电脑、掌上电脑、手机)等。本实施例中该通信设备以手机为例进行说明;该手机中预先安装有若干社交应用(如即时通讯应用),该手机的用户为一聋哑人,可称为聋哑用户;当聋哑用户需要通过该社交应用与某一正常用户进行交流时,可以启动该手机中的社交应用,并通过手机录像的方式录入自己的手语视频。手机在接收到该手语视频时,首先基于预设特征提取算法对手语视频的各视频帧进行特征提取,获取到各视频帧的手语特征,例如手势形状、各手指的指向、手部动作的运动轨迹等。对于该特征提取的过程所使用的预设特征 提取算法,可以是依靠机器学习得到的;也即先收集一定数量的手语图像样本,并建立初始特征提取模型,然后通过这些手语图像样本对初始特征提取模型进行迭代训练,不断调整模型参数,直至得到最优模型参数(或是满足预设次数的迭代训练次数、或是识别正确率达到一定阈值),从而根据该最优模型参数得到训练好的特征提取模型,该特征提取模型中的模型逻辑即为预设特征提取算法。当然,在实际中,该预设特征提取算法也可以根据静态规则设置的。
进一步,对于手语而言,其含义主要是靠手势以及手部动作运动轨迹等进行表达,因此在进行特征提取时,也主要是针对手语视频帧中的手部分图像进行。对此,为了提高特征提取的效率,可先对各视频帧进行一定的分割处理,再对分割后的图像进行特征提取。具体的,基于预设特征提取算法对所述手语视频的各视频帧进行特征提取,获得所述各视频帧的手语特征的步骤包括:
对所述各视频帧进行预处理,得到待提取图像;
手机在得到手语视频时,首先可对手语视频的各视频帧进行预处理,得到待提取图像,从而为后续的图像分割处理提供方便,例如图像二值化、降噪等操作。其中,二值化是指将视频帧转化为只含两种黑白颜色的二值图像,这是由于彩色图像所含信息量巨大,对其进行后续处理时计算量也会随之增大,花费的时间也会边长,因此为提高处理和识别的效率,可先对彩色图进行二值化处理;去噪则是通过滤波器或是其它方式解决数字图像由于噪声干扰而导致图像质量下降的问题。当然预处理的内容还可以根据实际情况添加或替换为其它的处理操作。
对所述待提取图像进行实例区域识别,并根据识别结果对所述待提取图像进行图像分割,得到手势区域图像;
在得到待提取图像时,将对该待提取图像进行实例区域识别,识别出其中的手势区域;对于该实例区域识别的过程,可以通过基于待测物的图像中每个像素点的像素值进行,例如通过各像素点的像素值以及临近相似点的像素值确定出像素突变点,进而得出各区域轮廓,然后对区域轮廓进行对象识别,确定各区域轮廓的含义,从而识别出手势区域轮廓;然后即可根据该轮廓进行图像分割,得到手势区域图像。
对所述手势区域图像进行特征提取,获得对应的手语特征。
在得到手势区域图像时,即可对该手势区域图像进行特征提取操作,获得对应的手语特征,从而无需对视频帧中的非手势区域图像进行相关检测和特征提取,降低了运算量,提高了特征提取的效率。
步骤S60,根据所述手语特征在预设手语库查询与所述各视频帧对应的手语样本帧, 并根据所述手语样本帧确定所述各视频帧的视频帧语义;
本实施例中,手机在提取得到手语特征时,即可根据该手语特征在预设手语库中查询与各视频帧对应的手语样本帧;其中该预设手语库中包括有标准手语样本帧、该手语样本帧的样本语义以及该手语样本帧的样本特征;而该手语样本帧的样本特征,也是通过上述步骤S50的预设特征提取算法对手语样本帧提取得到。在查询与各视频帧对应的手语样本帧时,即将视频帧的手语特征与各手语样本帧的样本特征进行比较,当某一样本特征与该手语特征的相似度达到一定阈值时,即可认为该样本特征所属的手语样本帧与该视频帧对应;而对于该相似度,则可以是通过距离的方式进行表征(如欧式距离等)。值得说明的是,若存在两个以上的样本特征与某一手语特征的相似度均达到一定阈值,则可将相似度最高的样本特征所属的手语样本帧作为与该视频帧对应的手语样本帧。在查询到与视频帧对应的手语样本帧时,手机获取该手语样本帧的样本含义,并根据该样本含义确定该视频帧的视频帧语音。
步骤S70,根据所述各视频帧的视频帧语义获取所述手语视频的手语视频语义,并根据所述手语视频语义生成对应的第二语音/文本信息;
本实施例中,在确定各视频帧的视频帧语义时,即可将各视频帧语义进行拼接,从而获得整段手语视频的手语视频语义,并根据该手语视频语义生成对应的第二语音/文本信息。当然,对于是生成语音信息还是文本信息,可以是根据聋哑用户的选择进行确定,又或是在手机系统中进行预先设置,又或者是两者均进行生成)。
步骤S80,将所述第二语音/文本信息发送至对应的智能终端,或播放/显示所述第二语音/文本信息。
本实施例中,手机得到对应的第二语音/文本信息时,即可将该第二语音/文本信息发送至正常用户所用的智能终端(如手机),以使得正常用户通过该智能终端看到该第二语音/文本信息,并获知聋哑用户所表达的含义。当然,手机在得到该第二语音/文本信息时,也可以是播放第二语音信息/显示第二文本信息,并根据聋哑用户的操作对该第二语音/文本信息执行发送、存储或是删除操作。
进一步的,本实施例中的手语视频转化语音/文本信息,是以“聋哑用户要向正常用户发送手语视频前进行转换”为例进行说明;而在实际中,还可以是聋哑用户通过手机直接向正常用户的智能终端发送手语视频,当正常用户的智能终端接收到该手语视频时,可根据正常用户的操作将该手语视频转化为语音信息/文本信息,其过程与上述实施例的各步骤类似,此处不再赘述,此时,正常用户的智能终端也可认为是本实施例中的基于人工智能的通信设备。再进一步,本实施例中的手语视频向语音/文本信息转化功能,可以是社交应用 中的某个功能,也可以是以API接口或SDK的方式集成在手机等终端中,以供终端中的应用进行调用。
本实施例中,在接收到手语视频时,基于预设特征提取算法对所述手语视频的各视频帧进行特征提取,获得所述各视频帧的手语特征;根据所述手语特征在预设手语库查询与所述各视频帧对应的手语样本帧,并根据所述手语样本帧确定所述各视频帧的视频帧语义;根据所述各视频帧的视频帧语义获取所述手语视频的手语视频语义,并根据所述手语视频语义生成对应的第二语音/文本信息;将所述第二语音/文本信息发送至对应的智能终端,或播放/显示所述第二语音/文本信息。通过以上方式,本实施例通过人工智能的方式实现手语视频向语音/文本的转换,使得正常用户可以方便地获知聋哑用户的手语含义,而聋哑用户也可以以手语表达的方式与正常用户进行社交通信,为双方提供了方便,提高了双方的使用体验。
值得说明的是,对于上述第一实施例的语音向手语的转换功能和第二实施例的手语向语音/文字的转换功能,可以是同时集成在同一基于人工智能的通信设备中,根据用户的选择和设置确定是否启动其中的某一功能,从而为用户的使用提供方便。
