具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例提供的逾期账单智能催收方法，可应用在如图1的应用环境中，该逾期账单智能催收方法应用在智能催收系统中，该智能催收系统包括客户端和服务器，其中，客户端通过网络与服务器进行通信。其中，客户端又称为用户端，是指与服务器相对应，为客户提供本地服务的程序。客户端可安装在但不限于各种个人计算机、笔记本电脑、智能手机、平板电脑和便携式可穿戴设备。服务器可以用独立的服务器或者是多个服务器组成的服务器集群来实现。
在一实施例中，如图2所示，提供一种逾期账单智能催收方法，以该方法应用在图1中的服务器为例进行说明，包括如下步骤：
S10：根据催收规则对原始案件进行筛选，获取入催案件，入催案件携带有逾期客户信息，逾期客户信息包括逾期客户的联系电话。
其中，催收规则指用于判断原始案件是否属于需要进行催收的案件的规则。原始案件指业务系统存储的需要还款的案件。入催案件指满足催收规则，在应还款日没有还款的案件。
具体地，智能催收系统获取业务系统发送的原始案件，原始案件携带有该原始案件的应还款日，智能催收系统在获取原始案件后，采用催收规则对原始案件进行筛选，筛选出在应还款日没有还款的案件，确定为入催案件。智能催收系统获取的入催案件携带有逾期客户信息，该逾期客户信息指逾期客户的个人信息，包括但不限于逾期客户的姓名、银行卡账号、还款金额、还款日期和联系电话。其中，逾期客户指在应还款日没有完成还款的 客户。
进一步地，为了防止从业务系统将原始案件发送到智能催收系统的过程中，客户信息泄露的情况发生，业务系统会在将原始案件发送给智能催收系统之前，采用RSA算法对原始案件进行加密。加密过程具体为，智能催收系统随机选择两个较大的素数A和B，计算素数A和素数B的乘积N。然后选择一个整数e与(A-1)*(B-1)的积互质，且e小于(A-1)*(B-1)，最后根据公式d*e≡1(mod(A-1)(B-1))计算d。则(N，e)称为公钥,(N，d)称为私钥。智能催收系统保留私钥，将公钥发送给业务系统，业务系统使用这个公钥对原始案件中的内容进行加密，生成对应的密文。相应地，在步骤S10之前，即智能催收系统根据催收规则对原始案件进行筛选，获取入催案件的步骤之前，智能催收系统使用私钥对原始案件进行解密。
由于RSA算法是目前最有影响力和最常用的公钥加密算法，安全性高，能够抵抗到目前为止已知的绝大多数的密码攻击，因此，使用RSA算法对原始案件进行加密和解密，可以提高数据在传输过程中的安全性。
S20：根据客户风险等级划分策略对入催案件的逾期客户信息进行划分，获取逾期客户名单，逾期客户名单包括逾期客户信息和与逾期客户信息相对应的逾期类型标识。
其中，客户风险等级划分策略指根据客户逾期还款金额、逾期还款天数和历史逾期还款次数等指标中的至少一个对客户进行风险等级划分的策略。逾期客户名单指根据客户风险等级划分策略对入催案件进行等级划分后得到的包括逾期客户信息的名单。该逾期客户名单用于存储逾期客户信息和与逾期客户信息对应的逾期类型标识。其中，逾期客户信息包括但不限于逾期客户的姓名、银行卡账号、还款金额、还款日期、联系电话、历史逾期还款天数和历史逾期还款次数。逾期类型标识指用于唯一识别逾期客户类型的标识。该逾期类型标识可以是特定的字符串、特定的数字或者特定的字母中的任何一种或者多种组合。
本实施例中的逾期客户类型包括但不限于高阶客户、低阶客户、惯逾客户、失联客户和老赖客户。其中，高阶客户指逾期还款天数超过60天的客户。低阶客户指逾期还款天数不超过60天的客户。惯逾客户指6个月内的历史逾期还款次数累计达到4次的客户。失联客户指根据入催案件中的联系电话无法联系到的客户。老赖客户指到了指定还款时间一直不还钱的客户。为了方便区分，每一种逾期客户名单对应一个逾期类型标识。例如：低阶客户对应低阶客户类型标识L，高阶客户对应高阶客户类型标识H，惯逾客户对应惯逾客户类型标识F，失联客户对应失联客户类型标识O，老赖客户对应老赖客户类型标识Z。
具体地，智能催收系统获取入催案件后，会从入催案件携带的逾期客户信息中获取逾期客户对应的历史逾期还款天数和历史逾期还款次数。然后基于预先设置的客户风险等级划分策略对逾期客户对应的历史逾期还款天数和历史逾期还款次数进行判断，确定入催案件中逾期客户对应的逾期客户类型，生成不同逾期类型标识对应的逾期客户名单。该逾期 客户名单中包括逾期客户信息和逾期类型标识，方便后续通过逾期类型标识获取与逾期类型标识对应的催收话术模板，完成对入催案件对应的逾期客户进行还款催收。
S30：获取与逾期类型标识相对应的催收话术模板，将逾期客户信息添加到催收话术模板对应的位置，获取目标催收话术。
其中，催收话术模板指智能催收系统中预先设置的用于对逾期客户进行还款催收的话术模板。其中，每一催收话术模板与一逾期类型标识相关联，以便基于逾期类型标识查找到对应的催收话术模板。本实施例中，催收话术模板以文本形式存储在智能催收系统中，方便后续将逾期客户信息添加到催收话术模板中生成目标催收话术。
具体地，获取逾期类型标识后，智能催收系统会根据获取的逾期类型标识选取与逾期类型标识对应的催收话术模板，然后将逾期客户信息中的姓名、银行卡账号、还款金额和还款日期添加到与该逾期类型标识相对应的催收话术模板中，获取目标催收话术。其中，目标催收话术指有逾期客户信息和催收话术模板组成的针对特定逾期客户类型的逾期客户的催收话术。
智能催收系统为了更加方便地服务客户，针对不同逾期客户类型的逾期客户，制定不同的催收话术模板。例如：低阶客户对应的催收话术为：XXX先生/女士，你好！您XX银行尾号为xxxx的信用卡逾期xxxx元，请尽快在xxxx日之前还款，如果没有异议并同意还款请确认……等待客户回答……，如果还有其他问题请拨打95511客户电话询问，谢谢您的来电！
高阶客户对应的催收话术为：XXX先生/女士，你好！您XX银行尾号为xxxx的信用卡已经逾期xxxx元，为避免影响您的个人征信，请尽快在xxxx日之前还款，如果没有异议请确认……等待客户回答……，如果客户有疑问直接转接到人工坐席处理，请按0。
本实施例中，通过逾期客户信息和与逾期类型标识相对应的催收话术模板，获取目标催收话术，避免人工催收时，由于催收策略使用不当引起客户不满的情况发生，同时为步骤S40中通过电话平台对逾期客户进行电话催收提供数据来源。
S40：调用电话平台，自动拨通逾期客户的联系电话并将目标催收话术转换成目标催收语音，获取逾期客户对目标催收语音反馈的逾期催收结果。
具体地，智能催收系统获取目标催收话术后，会从逾期客户名单中的逾期客户信息中获取逾期客户的联系电话。在获取目标催收话术和逾期客户的联系电话后，智能催收系统会调用内置的电话平台，该电话平台集成了自动拨号技术，电话平台会通过集成的自动拨号技术拨打逾期客户的联系电话对应的终端设备，在逾期客户的终端设备接通后，智能催收系统会将目标催收话术转换为目标催收语音，通过电话平台发送给逾期客户的终端设备，以使逾期客户可通过该终端设备听到该目标催收语音，从而实现对逾期客户进行电话催收。本实施例中，该终端设备具体为手机、具有通话功能的智能手表或其他设备。
本实施例中，将目标催收话术转化成催收语音，利用该催收语音对逾期客户进行电话催收，使得电话催收按照预设的标准的催收话术对逾期客户进行电话催收，避免催收人员 在电话催收过程中，加入自己的情绪，对逾期催收结果造成不良影响。
同时，智能催收系统还可获取内置的电话平台所获取到的逾期客户的通话语音，以便对逾期客户的通话语音进行分析，获取逾期催收结果。智能催收系统通过内置的电话平台对逾期客户进行电话催收，实现不需要人工干预即可完成电话催收的功能，提高催收工作效率。
本申请实施例所提供的逾期账单智能催收方法中，首先通过催收规则对原始案件进行筛选，将不符合催收规则的原始案件删除，获取符合催收规则的入催案件，有效减少智能催收系统从业务系统获取数据传输量，节省数据传输时间，提高催收效率。然后，根据智能催收系统预先设置的客户风险等级划分策略对入催案件的逾期客户信息进行划分，获取不同逾期客户类型对应的逾期客户名单，为了方便识别，逾期客户名单中包括逾期类型标识。接着，根据逾期类型标识获取与逾期类型标识对应的催收话术模板和逾期客户信息，生成针对特定逾期客户的目标催收话术，使得目标催收话术具有针对性。最后将逾期客户信息中逾期客户的联系电话和目标催收话术发送给智能催收系统内置的电话平台，通过电话平台对逾期客户进行电话催收，获取逾期催收结果，实现不需要人工干预即可完成电话催收的功能，提高催收工作效率。
在一实施例中，如图3所示，步骤S40，调用电话平台，自动拨通逾期客户的联系电话并将目标催收话术转换成目标催收语音，获取逾期客户对目标催收语音反馈的逾期催收结果，具体包括如下步骤：
S41：基于逾期客户的联系电话，调用电话平台对逾期客户的联系电话进行自动拔号。
本实施例中内置的电话平台指智能催收系统中内置的电话平台，该电话平台中集成了自动拨号技术。该自动拨号技术为CTI技术，其中，CTI技术是从传统的计算机电话集成(Computer Telephony Integration)技术发展而来的一种技术，CTI技术可以将计算机技术应用到电话系统中，能够自动地对电话中的指令信息进行识别处理，并通过建立有关的话路连接，而向用户传送预定的录音文件和转接来话的技术。
具体地，智能催收系统在获取逾期客户的联系电话后，会将该联系电话发送给内置的电话平台，电话平台在获取到逾期客户的联系电话后，会通过集成的自动拨号技术对对逾期客户的联系电话进行自动拔号。本实施例中，智能催收系统通过内置的电话平台中的自动拨号技术实现了自动拨打逾期客户的联系电话对应的终端设备，实现不需要人工干预即可完成电话拨号的功能。
S42：获取联系电话对应的终端设备反馈的接通信号，基于接通信号，采用TTS技术将目标催收话术转化成对应的目标催收语音，将目标催收语音发送给终端设备。
其中，接通信号指联系电话对应的终端设备在接通后反馈给电话平台的信号，该接通信号可用于识别联系电话对应的终端设备是否接通。TTS技术指将计算机自己产生或者外部输入的文字信息转变为汉语口语并输出的技术。目标催收语音指将目标催收话术中的内容转化成的催收语音。

进一步地，通过采用TTS技术将目标催收话术转化成对应的目标催收语音，使得催收语音标准化，避免人工催收时催收人员语气不当引起客户不满或者催收人员说话语音不标准而影响催收效果的情况发生。
S43：接收终端设备反馈的通话语音，对通话语音进行语义分析，获取逾期催收结果。
具体地，智能催收系统会通过电话平台接收终端设备反馈的来自逾期客户的通话语音。智能催收系统在获取到终端设备反馈的通话语音后，会对逾期客户的通话语音进行语义分析，判断逾期客户的通话语音中是否含有预先设置的“好的”、“OK”、“可以”和“等会就还”等携带同意还款单向的关键词。若通话语音中含有“好的”、“OK”、“可以”和“等会就还”等携带同意还款单向的关键词，则表示逾期客户同意还款，逾期催收结果为愿意还款。若通话语音中不含有“好的”、“OK”、“可以”和“等会就还”等携带同意还款单向的关键词，则表示逾期客户不同意还款，逾期催收结果为不愿意还款。
步骤S41-步骤S43，智能催收系统通过内置的电话平台对逾期客户的联系电话对应的终端设备进行自动拨号，在拨号成功后，通过TTS技术将目标催收话术转化成目标催收语音，发送给逾期客户对应的终端设备，完成和逾期客户的对话，获取逾期催收结果，达到逾期账单智能催收的效果，不需要人工催收，降低催收过程的人工成本，提高催收效率。
在一实施例中，如图4所示，步骤S43中，对通话语音进行语义分析，获取逾期催收结果，具体包括如下步骤：
S431：对通话语音进行扫描，判断通话语音是否包含预先设置的目标关键词。
其中，目标关键词指在智能催收系统中预先设置的用于识别逾期客户是否同意还款的关键词。即该目标关键词是携带同意还款单向的关键词。
具体地，智能催收系统通过电话平台获取到逾期客户的终端设备发送的通话语音后，会根据智能催收系统中的关键词识别技术对通话语音进行逐字扫描，获取通话语音的语音特征。判断通话语音中是否存在和目标关键词匹配的词语。本实施例中的关键词识别技术采用预先训练好的HMM(Hidden Markov Model隐式马尔科夫模型)对通话语音进行目标关键词识别。其中，预先训练好的HMM模型是预先训练好的存储在智能催收系统中，用于识别通话语音中是否存在“好的”、“OK”、“可以”和“等会就还”等目标关键词的模型。本实施例中，采用预先训练好的HMM模型识别通话语音中是否存在目标关键词，可以提高识别准确率。
或者，智能催收系统通过语音转换文字技术，将通话语音转化为文字。然后，采用分词工具对该通话语音对应的文字进行切分，去除停用词(分词、介词和代词等)、符号、数字和字母等词，获取待识别词。该待识别词指通话语音对应的文字中去除停用词、符号、数字和字母之后获取的词。最后，采用相似度算法对待识别词和目标关键词进行相似度计算，若相似度达到预设值，则确定通话语音中包含目标关键词。其中。本实施例中的相似度算法包括但不限于余弦相似度算法。
S432：若通话语音中包含有目标关键词，则获取携带有同意标识的逾期催收结果。
其中，同意标识指用于表示逾期客户同意还款的标识。具体地，当通话语音中包含“好的”、“OK”、“可以”和“等会就还”等目标关键词时，则表示逾期客户同意还款，与该逾期客户进行电话沟通后获取的逾期催收结果为同意还款。为了方便智能催收系统根据逾期催收结果执行后续步骤，智能催收系统在确定通话语音中包含目标关键词后，会对该逾期客户的逾期催收结果标注对应的同意标识，如“OK”或者“1”。
S433：若通话语音中不包含有目标关键词，则获取携带有不同意标识的逾期催收结果。
其中，不同意标识指用于表示逾期客户不同意还款的标识。具体地，当通话语音中不包含“好的”、“OK”、“可以”和“等会就还”等目标关键词时，则表示逾期客户不同意还款，与该逾期客户进行电话沟通后获取的逾期催收结果为不同意还款，智能催收系统在确定通话语音中不包含目标关键词后，会对该逾期客户的逾期催收结果标注对应的不同意标识，如“no”或者“0”。
步骤S431-步骤S433，智能催收系统通过对通话语音进行扫描，判断通话语音中是否含有目标关键词，确定逾期客户是否同意还款，达到无需人工干预即可实现逾期账单智能催收的目的。为了方便智能催收系统根据逾期催收结果执行后续步骤，智能催收系统在确定逾期客户语音通话中是否存在目标关键词后，会对逾期催收结果匹配对应的同意标识或者不同意标识，方便智能催收系统根据同意标识或者不同意标识执行对应的后续步骤。
在一实施例中，为了进一步保证电话沟通的有效性，智能催收系统在与逾期客户电话沟通完毕且逾期催收结果为同意还款后，还会通过短信和邮件的形式，发送对应的短信和邮件来提醒逾期客户进行还款。因此，逾期客户名单中还包括逾期客户的邮箱地址，如图5所示，在步骤S43，获取逾期催收结果的步骤之后，逾期账单智能催收方法还包括：
S44：若逾期催收结果携带有同意标识，则基于催收信息模板和逾期客户信息，获取有效催收信息。
其中，催收信息模板指预先设置好并存储在智能催收系统中的，用于提示逾期客户按时还款的信息模板。例如催收信息模板为：XXX先生/女士，您好！根据电话沟通，您已确认您平安银行尾号为xxxx的信用卡将在xxxx日之前完成还款金额xxxx元；如果还有其他问题请拨打95511客户电话询问，谢谢您的来电！
有效催收信息指将逾期客户信息添加到催收信息模板中得到的针对特定逾期客户的催收信息。
具体地，当逾期催收结果携带有同意标识时，智能催收系统会获取催收信息模板和逾期客户信息，将逾期客户信息中的姓名、银行卡账号、还款金额和还款日期添加到催收信息模板中，获取针对该特定逾期客户的有效催收信息。
S45：将有效催收信息通过逾期客户的联系电话或者逾期客户的邮箱地址发送给对应的终端设备。
智能催收系统在获取有效催收信息后，会通过逾期客户的联系电话将有效催收信息发送给该逾期客户的联系电话对应的终端设备。另外，若逾期客户名单中还包括逾期客户的邮箱地址时，智能催收系统会从逾期客户名单中获取该逾期客户对应的邮箱地址，然后以邮件的形式将有效催收信息发送给该逾期客户的邮箱地址对应的终端设备。采用短信或者邮件两种方式发送有效催收信息给逾期客户，可以进一步确保逾期客户能收到并查看该有效催收信息，提高催收质量。
在一实施例中，当智能催收系统在获取到携带有不同意标识的逾期催收结果后，会对该逾期客户进行进一步地的情况确认，首先确认该通话语音是不是来自逾期客户本人，若是逾期客户本人，则执行后续步骤；若不是逾期客户本人，则交给线下跟催工作人员催收。其中，跟催工作人员指通过找到逾期客户本人，当面对逾期客户进行逾期贷款催收的工作人员。如图6所示，在步骤S43，获取逾期催收结果的步骤之后，逾期账单智能催收方法还包括：
S46：若逾期催收结果携带不同意标识，则对通话语音进行声纹识别，确定通话语音的说话人是否为逾期客户本人。
其中，声纹识别也称为说话人识别，通过辨认说话人的声纹，确定说话人的身份。
具体地，如果获取的逾期催收结果携带有不同意标识，则表示逾期客户不同意还款。此时，智能催收系统会使用内置的声纹识别技术对逾期客户的通话语音进行识别，确定该通话语音是否为逾期客户本人的声音。若确定通话语音不是逾期客户本人的声音，则表示该联系电话对应的联系人发生变化，需要使用线下跟催的方法联系逾期客户本人，以催促该逾期客户本人及时还清逾期贷款。若确定通话语音是逾期客户本人的声音，执行步骤S47，对通话语音进行情绪识别，获取逾期客户的情绪识别结果。
S47：若通话语音的说话人为逾期客户本人，则调用预先存储的情绪识别模型对通话语音进行情绪识别，获取与逾期催收结果相对应的情绪识别结果。
具体地，若智能催收系统确定通话语音的说话人是逾期客户本人时，则需要对通话语音进行进一步分析，确定逾期客户本人在接收电话催收时的情绪，以便后续人工坐席与逾期客户进行电话沟通时，采用照顾逾期客户情绪的催收策略和逾期客户进行电话沟通，避免催收人员在催收过程中因为催收策略使用不当引起客户投诉的问题发生。
步骤S46-步骤S47，智能催收系统在获取携带有不同意标识的逾期催收结果后，会首先对逾期客户的通话语音进行声纹识别，确认该通话语音是否来自本人；若通话语音来自逾期客户本人，则对通话语音进行情绪识别，获取情绪识别结果，方便人工坐席采取恰当 的催收策略与逾期客户进行电话沟通，降低客户投诉率。
在一实施例中，如图7所示，步骤S46，对通话语音进行声纹识别，确定通话语音的说话人是否为逾期客户本人，具体包括如下步骤：
S461：对通话语音进行预处理，获取待识别语音。
其中，待识别语音指对通话语音进行预处理后得到语音。具体地，对通话语音进行声纹识别之前，需要对通话语音进行预处理，去除通话语音中的噪声(包括语音通话中的静音和环境噪音)，获取待识别语音。其中，预处理的过程具体包括：首先，对通话语音进行预加重处理；然后对预加重处理后的通话语音进行分帧和加窗运算；最后，使用端点检测技术对通话语音进行处理，去除通话语音中的噪声，以获取待识别语音。
S462：对待识别语音进行语音特征提取，获取待识别语音对应的待识别语音特征。
具体地，获取待识别语音后，将待识别语音通过快速傅里叶变换、对数运算和离散余弦变换处理后，获取待识别语音特征。该待识别语音特征为MFCC特征。
S463：采用声纹识别模型对待识别语音特征和逾期客户对应的原始语音特征进行声纹识别，确定通话语音的说话人是否为逾期客户本人。
其中，声纹识别模型指预先训练好的存储在智能催收系统中的用于识别通话语音的说话人是否为逾期客户本人的模型。现有多种成熟的声纹识别模型，包括但不限于GMM-UBM(Gaussian mixture model-universal background model，混合模型-通用背景模型)模型和i-vector(identity-vector,身份认证向量)模型。本实施例中的声纹识别模型采用i-vector模型作为声纹识别模型。原始语音特征指智能催收系统预先存储的该逾期客户的说话语音对应的语音特征。可以理解地，该逾期客户的说话语音经过与步骤S461-S462相对应的预处理和特征提取之后，即可获取到对应的原始语音特征，并将该原始语音特征与逾期客户信息关联存储，以便后续进行声纹识别时可直接调用，无需在识别过程中进行相应的处理，以提高识别效率。
具体地，当获取待识别语音特征后，智能催收系统会根据逾期客户的客户信息查找智能催收系统中预先存储的与该逾期客户信息对应的原始语音特征。然后，将该逾期客户的待识别语音特征和原始语音特征输入到预先训练好的声纹识别模型中，获取待识别语音特征和原始语音特征各自对应的i-vector向量；再计算待识别语音特征和原始语音特征各自对应的i-vector向量的空间距离，若空间距离大于根据实际情况设置的距离阈值，则可以确定通话语音的说话人为逾期客户本人。本实施例中的空间向量距离采用余弦距离计算公式计算。
步骤S461-步骤S463，通过获取通话语音对应的待识别语音特征，采用声纹识别模型对待识别语音特征和逾期客户对应的原始语音特征进行识别，确定通话语音的说话人是否为逾期客户本人，若为逾期客户本人，则表示逾期客户不愿意还款，需要通过后续步骤对通话语音进行情绪识别，方便坐席人员采用人工沟通的方式了解逾期客户不还款的原因。
在一实施例中，如图8所示，步骤S47，调用预先存储的情绪识别模型对通话语音进 行情绪识别，获取与逾期催收结果相对应的情绪识别结果，具体包括如下步骤：
S471：将待识别语音特征输入到情绪识别模型中，获取待识别语音特征对应的待确认情绪，待确认情绪携带有情绪得分。
其中，情绪识别模型是预先训练好并存储在智能催收系统中的用于识别逾期客户情绪的模型。本实施例中的情绪识别模型采用基于向量机的情绪识别模型。待确认情绪包括但不限于情绪识别模型识别出的说话人说话时的高兴、愤怒、悲伤、烦噪和平静等情绪。具体地，在根据待识别语音特征确认通话语音的说话人为逾期客户本人的声音后，智能催收系统将待识别语音特征输入到预先训练好的情绪识别模型中，对待识别语音特征进行情绪识别，以获取通话语音对应的逾期客户在说话时的各种待确认情绪的情绪得分。本实施例中的情绪识别模型在获取待识别语音特征后，会分别对待识别语音特征中的高兴、愤怒、悲伤、烦噪和平静等待确认情绪进行情绪得分计算，获取不同的待确认情绪对应的情绪得分。采用基于向量机的情绪识别模型计算复杂度较小，可根据少数支持向量决定最终结果，在训练过程中有助于抓住关键样本，剔除冗余样本，具有较好的鲁棒性。
S472：对待确认情绪携带的情绪得分进行计算，获取情绪识别结果。
其中，情绪识别结果指对待确认情绪携带的情绪得分进行计算，获取能最终表示逾期客户在被催收时情绪的结果。具体地，在获取通话语音中不同的待确认情绪的情绪得分后，情绪识别模型会比较各待确认情绪携带的情绪得分，将情绪得分最大的待确认情绪作为最终的情绪识别结果输出。智能催收系统会将该情绪识别结果和对应的逾期客户信息发送给人工坐席，便于人工坐席根据情绪识别结果采用合适的催收策略对逾期客户进行电话沟通。
步骤S471-步骤S472，将待识别语音特征输入到情绪识别模型中，获取待识别语音特征对应的待确认情绪；根据待确认情绪携带的情绪得分，获取逾期客户的情绪识别结果。通过情绪识别模型对逾期客户的情绪进行智能判断，提高情绪识别的准确性和判断速度，方便人工坐席根据情绪识别结果采用合适的催收策略对逾期客户进行电话沟通。。
本申请实施例所提供的逾期账单智能催收方法中，首先通过催收规则对原始案件进行筛选，将不符合催收规则的原始案件删除，获取符合催收规则的入催案件。然后根据智能催收系统预先设置的客户风险等级划分策略对入催案件的逾期客户信息进行划分，获取不同逾期客户类型对应的逾期客户名单，方便后续针对不同逾期客户类型采用不同的催收话术与逾期客户进行电话沟通。接着根据逾期客户名单中的逾期类型标识获取与逾期类型标识对应的催收话术模板和逾期客户信息，生成针对特定逾期客户的目标催收话术，通过电话平台的自动拨号技术对逾期客户进行电话催收，获取逾期催收结果，确定逾期客户是否有还款意愿，提高催收工作效率，降低催收成本。若逾期催收结果中携带有同意标识，则发送有效催收信息给逾期客户的终端设备；若逾期催收结果中携带有不同意标识，则对逾期客户的通话语音进行声纹识别和情绪识别，最终将情绪识别结果反馈给人工坐席，使得人工坐席根据情绪识别结果对逾期客户进行电话催收，降低因为催收策略使用不当引起客 户投诉的投诉率。
应理解，上述实施例中各步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
