这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在智能家电领域,通常是通过语音交互对智能家电设备进行控制。在一个家庭场景中,可能存在属于不同领域的智能家电设备,语音交互中的语音数据会被不同领域的智能家电设备接收,每个领域的智能家电设备在服务器上都有自己独立的指令识别模型,这个时候服务器就会通过树形流的方式将语音数据同时下发到每个领域的智能家电设备具有的指令识别模型,不同领域的指令识别模型识别语音数据是否适配本领域的智能家电设备。这种语音数据的识别和处理方法中,多个指令识别模型的同时运行会对服务器造成压力,导致服务器负载压力过大,从而导致服务器宕机风险增大。
基于此,本公开提供一种语音数据处理方法、装置及电子设备、存储介质,在获取到语音数据后,将语音数据转换为文本信息,再识别出该文本信息指示的家电设备领域类别,根据该文本信息指示的家电设备领域类别确定出与该目标家电设备的领域类别匹配的目标指令识别模型,再基于该目标指令识别模型识别该文本信息后生成执行指令。向该目标家电设备发送执行指令,使得该目标家电设备执行该语音数据指示的操作。由此,在获取到语音数据时,只调用领域分类模型和一个指令识别模型来对语音数据进行处理,不需要调用所有的指令识别模型都对语音数据进行处理,减少了服务器的负载压力,进而减少了服务器宕机的风险。
本公开提供的语音数据处理方法应用于电子设备,该电子设备例如智能家居系统所用 的计算机、智能家居系统所用的服务器等。图1为本公开提供的语音数据处理方法的应用示意图,图中,该电子设备在获取外部输入的语音数据后,将语音数据转换为文本信息,再将文本信息输入至领域分类模型,确定出目标家电设备的领域类别,再根据目标家电设备的领域类别确定对应的目标指令识别模型。基于该目标指令识别模型处理该文本信息后输出执行指令至目标家电设备。
请参考图2,本公开实施例一提供一种语音数据处理方法,包括:
S210,获取语音数据,并将该语音数据转换为文本信息。
该语音数据由用户定义,例如用户说的“开启洗衣机”就是一个语音数据。该电子设备在接收到语音数据后,将该语音数据转换为可以处理的文本信息,例如语音数据“开启洗衣机”转换后的文本信息为“开启洗衣机”。
该语音数据可以是短句,也可以是长句,对应的,该文本信息可以为字数较少的语句,也可以是字数较多的语句。该语音数据可以是包含一个操作,也可以是包含多个操作,例如语音数据“开启洗衣机后开始洗衣服”。
S220,将该文本信息输入至领域分类模型,得到目标家电设备的领域类别。
该领域分类模型用于识别该文本信息后确定出该文本信息所指示的目标家电设备所属的领域类别。例如该文本信息为“开启洗衣机后开始洗衣服”,将该文本信息输入至该领域分类模型后,得到的该目标家电设备的领域类别为“洗衣机”。
该领域分类模型用于根据该文本信息预测并输出目标家电设备的领域类别,在进行预测时,该领域分类模型会计算该文本信息对应于该领域分类模型中的所有领域类别的概率,再从多个概率里面筛选出最大的概率对应的领域类别为该文本信息对应的目标家电设备的领域类别。该领域分类模型中的领域类别例如为洗衣机、电视机、扫地机器人等,文本信息“开启洗衣机后开始洗衣服”被该领域分类模型处理后,属于洗衣机的概率可能是90%,属于电视机的概率可能是20%,属于扫地机器人的概率可能是60%,则预测出来的文本信息“开启洗衣机后开始洗衣服”对应的目标家电设备的领域类别是洗衣机。
在将该文本信息输入至该领域分类模型之前,还需要创建该领域分类模型。在创建该领域分类模型时,需要先获取初始领域分类模型,再对该初始领域分类模型进行训练,得到该领域分类模型。在对该初始领域分类模型进行训练之前,先获取该初始领域分类模型的训练集,该训练集包括多条文本信息,每条文本信息都标准有原始领域类别。再根据该初始领域分类模型的训练集对该初始领域分类模型进行训练,当该初始领域分类模型输出该初始领域分类模型的训练集中每条文本信息的预测领域类别时,输出的每条文本信息的预测领域类别与每条文本信息的原始领域类别之间的输出损失均在预设损失内时,完成对该初始领域分类模型的训练,得到该领域分类模型。
可选的,该初始领域分类模型为预训练模型ALBERT和卷积神经网络模型的融合模型,在融合后,该预训练模型ALBERT的输出为该卷积神经网络模型的输入。
因为语音数据有两个特点,一是指令的文本较短,而是指令的指示范围不确定,用户可能说出各种各样的句子。所以,在创建该领域分类模型的时候,要求领域分类模型既要具有对短文本局部和全局的特征能够充分学习,又要具有良好的文本泛化能力,以便更充分得理解语音数据转换后的文本信息。基于此原因,在初始领域分类模型中设置了卷积神经网络模型TextCNN,卷积神经网络模型TextCNN对文本浅层特征的抽取能力很强,在 短文本分类时的效果很好。为了增加该领域分类模型的文本泛化能力,在该初始领域分类模型中引入该预训练模型ALBERT,该预训练模型ALBERT在预训练时已经学习到了大量的百科问答、日常对话、新闻报道等语料中的特征信息,可以很好的增强对非控制类语料的理解能力。且该预训练模型ALBERT结构简单、推理速度快,因此在线上部署后可以很好的适应部署环境。
S230,根据该目标家电设备的领域类别,从多个指令识别模型中确定与该目标家电设备的领域类别匹配的目标指令识别模型。
每个领域类别在该电子设备上都具有独立的指令识别模型,在步骤S220确定出该目标家电设备的领域类别后,就可以确定出与该目标家电设备的领域类别对应的目标指令识别模型。
S240,基于该目标指令识别模型识别该文本信息后生成执行指令,该执行指令用于指示目标家电设备执行该语音数据指示的操作。
该目标指令识别模型在识别该文本信息后可以确定出该文本信息所指示的目标家电设备的信息和该目标家电设备要执行的操作。在识别出该目标家电设备的信息和该目标家电设备要执行的操作后,将这些信息打包为执行指令。
S250,向该目标家电设备发送该执行指令。
该目标家电设备接收到该执行指令后,执行该执行指令中指示的操作,由此完成语音交互控制目标家电设备的过程。
综上,本实施例提供的在方法获取到语音数据后,将语音数据转换为文本信息,再识别出该文本信息指示的目标家电设备的领域类别,根据该目标家电设备的领域类别确定出目标指令识别模型,再基于该目标指令识别模型识别该文本信息后生成执行指令。向该目标家电设备发送执行指令,使得该目标家电设备执行该语音数据指示的操作。由此,在获取到语音数据时,只调用领域分类模型和一个指令识别模型来对语音数据进行处理,不需要调用所有的指令识别模型都对语音数据进行处理,减少了服务器的负载压力,进而减少了服务器宕机的风险。
请参见图3,本公开实施例二还提供一种语音数据处理方法,在实施例一的基础上对领域分类模型的创建过程进行进一步得描述。本实施例提供的方法包括:
S310,获取初始领域分类模型,该初始领域分类模型为预训练模型ALBERT和卷积神经网络模型的融合模型,该预训练模型ALBERT的输出为该卷积神经网络模型的输入。
如步骤S220所描述的,卷积神经网络模型TextCNN对文本浅层特征的抽取能力很强,在短文本分类时的效果很好。该预训练模型ALBERT在预训练时已经学习到了大量的百科问答、日常对话、新闻报道等语料中的特征信息,可以很好的增强对非控制类语料的理解能力。且该预训练模型ALBERT结构简单、推理速度快,因此在线上部署后可以很好的适应部署环境。
S320,获取该初始领域分类模型的训练集,该训练集包括多条文本信息,每条文本信息标注有原始领域类别。
文本信息上标注的原始领域类别可以是由研发人员定义。该训练集中的文本信息数量应该尽可能得多,以提高该初始领域分类模型的训练效果。
S330,将该初始领域分类模型的训练集中的第一文本信息输入至该初始领域分类模型, 得到该第一文本信息属于预设领域类别集中每个预设领域类别的概率值。
该第一文本信息是该初始领域分类模型的训练集中的任意一个文本信息,该预设领域类别例如为“洗衣机”、“电视机”、“扫地机器人”等。将该第一文本信息输入至该初始领域分类模型时,该第一文本信息其实是作为数值输入的,为保持每条文本信息对应的数值长度相同,以提高模型训练效果,需要将该第一文本信息补充或删除至预设数值长度的文本信息后输入至该初始领域分类模型中的预训练模型ALBERT。当该第一文本信息对应的数值长度大于该预设数值长度时,对该第一文本信息中的字进行删除,当该第一文本信息对应的数值长度小于该预设数值长度时,对该第一文本信息中的字进行补充。
将该第一文本信息输入至该初始领域分类模型后,该第一文本信息先输入至该预训练模型ALBERT,由该预训练模型ALBERT输出该第一文本信息中每个字的第一特征向量。再将该第一文本信息中每个字的第一特征向量依序输入至该卷积神经网络模型中。
如图4所示,在本实施例中,该卷积神经网络模型包括N个不同的卷积层(图4以6个不同的卷积层为例),N为大于3的整数,每个卷积层具有不同的感受野。将该第一文本信息中每个字的第一特征向量时,按照第一卷积层至第N卷积层的顺序,将该第一文本信息中每个字的第一特征向量依序输入至该N个不同的卷积层中的第一卷积层至第N卷积层。该第一卷积层至该第N卷积层可以同时以该第一文本信息为处理样本,对该第一文本信息中每个字的第一特征向量进行提取,也就是说该第一文本信息被每个卷积层都处理了一遍。在进行该第一文本信息中每个字的第一特征向量的提取时,基于每个卷积层的感受野的大小对该第一文本信息中每个字的第一特征向量进行依次提取,得到该第一文本信息的N个维度的特征向量。
再将该第一文本信息的N个维度的特征向量拼接为一个维度的特征向量,并将拼接得到的特征向量输入至该卷积神经网络模型的全连接层,得到该第一文本信息属于预设领域类别集中每个领域类别的概率值。该预设领域类别集例如包含“洗衣机”、“电视机”、“扫地机器人”等领域类别。
如图4所示,一共有6个不同的卷积层,分别为Conv-3、Conv-4、Conv-5、Conv-6、Conv-7、Conv-8。第一卷积层Conv-3的感受野大小为3,步长为1,则每次按照字的排序依次提取3个字的第一特征向量进行处理后输出该第一文本信息第一个维度的特征向量。第二卷积层Conv-4的感受野大小为4,步长为1,则每次按照字的排序依次提取4个字的第一特征向量进行处理后输出该第一文本信息第二个维度的特征向量。第三卷积层Conv-5的感受野大小为5,步长为1,则每次按照字的排序依次提取5个字的第一特征向量进行处理后输出该第一文本信息第三个维度的特征向量。第四卷积层Conv-6的感受野大小为6,步长为1,则每次按照字的排序依次提取6个字的第一特征向量进行处理后输出该第一文本信息第四个维度的特征向量。第五卷积层Conv-7的感受野大小为7,步长为1,则每次按照字的排序依次提取7个字的第一特征向量进行处理后输出该第一文本信息第五个维度的特征向量。第六卷积层Conv-8的感受野大小为8,步长为1,则每次按照字的排序依次提取8个字的第一特征向量进行处理后输出该第一文本信息第六个维度的特征向量。
将该第一文本信息的六个维度的特征向量拼接为一个维度的特征向量后,将拼接得到的特征向量输入至该卷积神经网络模型的全连接层(Dense)。该卷积神经网络模型的全连接层对该拼接得到的一个维度的特征向量进行全局语义信息提取,输出该第一文本信息属 于预设领域类别集中每个领域类别的概率值。
可选的,在得到该第一文本信息的N个维度的特征向量之后,也就是将该第一文本信息的六个维度的特征向量拼接为一个维度的特征向量之前,还可以对该第一文本信息的N个维度的特征向量均进行最大池化处理,以得到去噪的该N个维度的特征向量。
可选的,每个卷积层在接收到该第一文本信息中每个字的第一特征向量后,通过Gelu激活函数激活卷积层中的随机失活层Dropout,以增加该领域分类模型的非线性特征,并且防止该初始领域分类模型在训练过程中出现过拟合的问题(过拟合:过度学习文本信息与领域类别标识有问题的文本信息)。除此之外,还基于卷积层中的层法线Layer normal对该第一文本信息中每个字的第一特征向量进行归一化操作,使得输出的该第一文本信息的特征向量是以正态分布的形式输出的,以提高卷积层输出的特征向量的稳定性。
S340,筛选出该第一文本信息属于预设领域类别集中每个预设领域类别的概率值中最大的概率值对应的预设领域类别为该第一文本信息的预测领域类别。
该第一文本信息属于预设领域类别集中每个领域类别的概率值再经过该卷积神经网络的Softmax计算,从该第一文本信息属于预设领域类别集中每个领域类别的概率值中确定出最大的概率值对应的领域类别为该第一文本信息对应的领域类别。
S350,循环执行步骤该将该初始领域分类模型的训练集中的第一文本信息输入至该初始领域分类模型,直到得到该训练集中每条文本信息的预测领域类别。
即,遍历该训练集中所有的文本信息,对训练集中的每条文本信息执行步骤S330至步骤S340,直到得到该训练集中每条文本信息的预测领域类别。
S360,计算该初始领域分类模型输出的每条文本信息的预测领域类别与每条文本信息的原始领域类别之间的输出损失。
初始领域分类模型的训练过程中,需要将该第一文本信息的预测领域类别与该第一文本信息标注的原始领域类别进行对比,确定出该初始领域分类模型在预测该第一文本信息所属领域类别时的输出损失,以输出损失更新模型的方式对该初始领域分类模型进行迭代优化。迭代优化的过程如步骤S370,即根据每条文本信息的输出损失与预设损失之间的比较结果不断得优化该初始领域模型,使得该初始领域模型输出的每条文本信息的输出损失均小于该预设损失。
S370,在每条文本信息对应的该输出损失均小于预设损失时,确定对该初始领域分类模型的训练结束,得到该领域分类模型。
在每条文本信息对应的该输出损失均小于预设损失时,代表该初始领域分类模型能够在要求的准确度之下预测出文本信息所属的领域类别,此时结束该初始领域分类模型的训练,得到该领域分类模型。该初始领域分类模型的训练集中文本信息的数量越多,该初始领域分类模型的训练效果越好。
S380,获取语音数据,对该语音数据进行处理后向该目标家电设备发送执行指令。
步骤S380所描述的内容即步骤S210至步骤S250所描述的内容,具体可以参考步骤S210至步骤S250中的相关描述,此处不再赘述。
本实施例提供的语音数据处理方法在实施例一的基础上进一步描述了该领域分类模型的创建过程。在对开防域的短文本分类时,使用预训练模型ALBERT增强最终训练得到的该领域分类模型对非控制类语料的理解能力,且该预训练模型ALBERT结构简单、推理 速度快,因此在线上部署后可以很好的适应部署环境。在卷积神经网络模型TextCNN中使用更多的卷积层和更大的卷积核,以增大卷积层的容量,以更好得保存文本信息与上下文之间的特征信息,使得文本信息的分析更加准确。除此之外,还使用了随机失活层Dropout来防止该初始领域分类模型学习时可能会出现的过拟合问题,使用层法线Layer normal保证输出的特征向量分布稳定,提高该领域分类模型的性能。综上,本实施例提供的方法中创建的该领域分类模型对文本信息的领域类别的识别率更高,该领域分类模型本身也更稳定,因此可以很好得应用在对语音数据的文本信息对应的领域类别的分析上,以提高预测文本信息的领域类别的准确率和速度。
