Description
本发明涉及终端语音解锁领域,尤其涉及一种终端的语音解锁方法及终端。
随着智能手机的快速普及,人机交互技术被越来越广泛地应用到各个领域,较普遍的是人机之间的语音交互。典型的应用包括siri、语音助手等。随之产生的还有语音解锁技术,即机器对接收到的语音进行判断,确定是否进行解锁。
目前的语音解锁技术主要是提取接收到的语音信息的声纹,进一步判断该声纹与用户预先训练的声纹模型是否相同,相同则解锁。
但是,声纹的唯一性特征仍未被发现,也就说不同的人的声纹有可能相同。因而导致目前的语音解锁方案准确度不高,同时只能用于安全性能要求不高的场合。
发明内容
本发明的实施例提供一种终端的语音解锁方法及终端,能够提高语音解锁方案的准确性及安全性。
为达到上述目的,本发明的实施例采用如下技术方案:
第一方面,公开了一种终端的语音解锁方法,包括:
首先,在所述终端的锁屏界面随机显示一串文本字符,所述文本字符包括第一类字符和第二类字符;其中,所述第二类字符用于指示待输入密码字符在所述文本字符中的位置,所述第一类字符和所述待输入密码字符组成解锁所述终端的密码字符串。这里,第一类字符可以是数字、字母等,第二类字符可以是“_”“*”等,提示语音解锁时需要在第二类字符对应的位置填入密码。另外,这里的“填入”并非用户手动输入,而是用户在阅读解锁字符串时需要以发声形式填入。示例的,终端显示“23_8_9_0”,即指示用户在3和
8之间、8和9之间以及9和0之间三处填入密码。若用户填入的密码为abc,那么用户阅读“23a8b9c0”。另外,所述待输入密码字符即为用户预设的密码。若终端真实用户预先设置的文本密码即所述待输入密码为269,则所述密码字符串为“23286990”,即所述待输入密码在所述密码字符串中的位置与所述第二类字符在所述文本字符中的位置相同。
接着,所述终端接收语音信息,从所述语音信息中识别出解锁字符串。即对用户依次阅读的所述第一类字符、在第二类字符所在位置填入的密码进行录音,因此可以解析出用户阅读的解锁字符串。当然,由于用户按照终端解锁界面显示的文本字符的顺序阅读所述第一类字符,同时在第二类字符所在位置语音填入的密码,那么所述语音信息同时指示了所述第一类字符和用户语音输入的密码的相对顺序。
进而,所述终端判断所述解锁字符串与所述密码字符串是否匹配。其中,终端随机显示的第一类字符可以与所述待输入密码字符相同,也可以不同。
若所述解锁字符串与所述密码字符串匹配,所述终端则解析所述语音信息,获取所述语音信息的声纹;
所述终端判断所述所述语音信息的与预设声纹是否相同。
若所述所述语音信息的声纹与预设声纹相同,则解锁所述终端。
现有语音解锁中,随机显示解锁文本,随后接收用户阅读的解锁语音,对解锁语音进行分析获取一个声纹,若该声纹与预先提取的声纹模型相同,则解锁。但是,目前技术提取的声纹并不是声音的唯一性特征,可能存在不同人的声纹相同,因此目前的语音解锁方案准确度不高。或者,解锁文本是固定的,终端用户阅读解锁文本语音解锁时,容易被盗听密码,会导致安全性降低。
本发明提供的终端的语音解锁方法,随机显示包括第一类字符与第二类字符的文本字符,第二类字符用于指示待输入密码的位置。用户阅读时需要在第二类字符所在位置填入密码,终端解析用户输
入的语音信息获得解锁字符串,解锁字符串与密码字符串匹配且语音信息的声纹识别通过后,才能够解锁。将文本密码与声纹识别结合在一起,避免声纹不唯一导致的解锁准确度不高的问题,能够提高语音解锁的准确度。另外,由于需要填入密码的第二类字符在解锁界面上显示的文本字符中的位置是不固定的,因此,密码不易被盗取,提高了语音解锁的安全性。
结合第一方面,在第一方面的第一种可能的实现方式中,所述在所述终端的锁屏界面显示一串随机的文本字符之前,所述方法还包括:
所述终端根据所述第一类字符串和所述待输入密码构成所述密码字符串。在此,待输入密码是用户预先设定的文本密码,其所在位置与所述第二类字符所在位置相同。具体实现中,终端随机生成第一类字符,如:“23890”,将待输入密码abc随机插入第一类字符中生成密码字符串,如“23a8b9c0”。另外,若第二类字符为“_”,则终端随机显示的文本字符可以是:“23_8_9_0”。
结合第一方面或第一方面的第一种可能的实现方式,在第一方面的第二种可能的实现方式中,所述在所述终端的锁屏界面显示一串随机的文本字符之前,所述方法还包括:
所述终端接收设置指令,生成预设字符集合;
所述终端显示训练字符串,所述训练字符串包括所述预设字符集合的所有字符;
所述终端接收训练语音信息,所述训练语音信息指示用户阅读所述训练字符串;
所述终端解析所述训练语音信息,获得所述预设声纹。
这里是终端的真实用户预先反复(如:至少阅读三次)阅读终端显示的预设字符集合的所有字符,终端收集用户的语音,对语音进行解析,就能够获得所述预设声纹,即所述终端的真实用户的声纹。
结合第一方面或第一方面的第一或第二种可能的实现方式,在
第一方面的第三种可能的实现方式中,所述终端判断所述解锁字符串与所述密码字符串是否匹配具体包括:
判断所述解锁字符串与所述密码字符串包括的字符是否相同;
若所述解锁字符串与所述密码字符串包括的字符相同,则判断每一个字符在所述解锁字符串中的位置与在所述密码字符串中的位置是否相同;
若每一个字符在所述解锁字符串中的位置与在所述密码字符串中的位置相同,则确定所述解锁字符串与所述密码字符串匹配。
也就是说,在用户阅读的语音中提取的解锁字符串必须与预设的密码字符串包括的字符一一对应,才能认为用户填入的密码字符与所述预设密码字符串匹配。示例的,预设的密码字符串为1268,只有用户阅读的解锁字符串为1268才能确定所述解锁字符串与所述密码字符串匹配,若用户阅读的解锁字符串为8621或2681,则不能认为所述解锁字符串与所述密码字符串匹配。
结合第一方面,在第一方面的第四种可能的实现方式中,若所述解锁字符串与所述密码字符串不匹配,所述终端则提示解锁失败。
结合第一方面,在第一方面的第五种可能的实现方式中,若所述终端确定所述语音信息的声纹与预设声纹不相同,所述终端则提示解锁失败。
具体地,可以在终端屏幕的特定区域显示文本——“解锁失败”。
当然,终端提示解锁失败后,还可以再次随机显示一个解锁字符串。
结合第一方面的第二至第五种可能的实现方式中,在第一方面的第六种可能的实现方式中,所述第一类字符属于预设字符集合,所述第二类字符不属于所述预设字符集合。
结合第一方面,在第一方面的第七种可能的实现方式中,在所述终端的锁屏界面随机显示一串文本字符之前,所述方法还包括:
所述终端进入锁定状态;所述终端接收解锁指令。
可以是,终端的任意一个按键被按中,或是某个特定按键(如:
电源键、锁屏键等)被按中。
结合第一方面,或第一方面的第一至第三种可能的实现方式中的任一种,在第一方面的第八种可能的实现方式中,所述在所述终端的锁屏界面随机显示一串文本字符之后,所述方法还包括:
提示用户语音输入所述解锁字符串。
具体实现中,可以是通过语音提示用户阅读解锁界面显示的第一类字符并在第二类字符所在位置填入密码,语音输入所述解锁字符串。当然也可以在解锁界面显示文本文字,提示用户语音输入所述解锁字符串,如在解锁界面显示“请阅读已显示的数字同时在未显示数字处填入密码”。
第二方面,公开了一种终端,包括:
显示单元,用于在所述终端的锁屏界面随机显示一串文本字符,所述文本字符包括第一类字符和第二类字符;其中,所述第二类字符用于指示待输入密码字符在所述文本字符中的位置,所述第一类字符和所述待输入密码字符组成解锁所述终端的密码字符串;
接收单元,接收语音信息;
识别单元,用于从所述语音信息中识别出解锁字符串;

所述判断单元还用于,判断所述所述语音信息的声纹与预设声纹是否相同;

现有语音解锁中,随机显示解锁文本,随后接收用户阅读的解锁语音,对解锁语音进行分析获取一个声纹,若该声纹与预先提取的声纹模型相同,则解锁。但是,目前技术提取的声纹并不是声音的唯一性特征,可能存在不同人的声纹相同,因此目前的语音解锁
方案准确度不高。或者,解锁文本是固定的,终端用户阅读解锁文本语音解锁时,容易被盗听密码,会导致安全性降低。
本发明提供的终端,随机显示包括第一类字符与第二类字符的文本字符,第二类字符用于指示待输入密码的位置。用户阅读时需要在第二类字符所在位置填入密码,终端解析用户输入的语音信息获得解锁字符串,解锁字符串与密码字符串匹配且语音信息的声纹识别通过后,才能够解锁。将文本密码与声纹识别结合在一起,避免声纹不唯一导致的解锁准确度不高的问题,能够提高语音解锁的准确度。另外,由于需要填入密码的第二类字符在解锁界面上显示的文本字符中的位置是不固定的,因此,密码不易被盗取,提高了语音解锁的安全性。

为了更清楚地说明本发明实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,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,都属于本发明保护的范围。
现有的语音解锁方案,包括训练过程和认证过程。具体地,训练过程如下:
1)终端随机产生文本密码或由终端的真实用户指定文本密码。
2)用户多次阅读终端显示的文本密码,机器进行录音。
这里的用户即终端的真实用户。
3)终端针对录音进行解析,得到终端的真实用户的声纹模型。
另外,认证过程如下:
1)终端显示文本密码。
2)用户阅读文本密码,终端进行录音。
这里的用户可以是终端的真实用户,也可以是任意一个欲使用终端的用户。
3)语音识别,即终端判断用户所说的内容与文本密码是否一致。一致,则进入下一步;不一致,则认证失败。
4)声纹识别,即终端判断录音的声纹与声纹模型是否相同。是,
则认证成功;否则,认证失败。
通常,用户根据终端显示的文本密码阅读发生错误的概率很低,可见现有语音解锁方案的安全性及准确性严重依赖于声纹识别。由于当语音时长只有数秒时,声纹识别的准确度非常低,进而导致认证过程准确度及安全度较低。
本发明的原理在于,在语音解锁过程中,不显示预先设置的文本密码。需要用户阅读时在相应位置填入密码,填入密码正确且声纹识别通过后,才能够解锁。将文本密码与声纹识别结合在一起,避免声纹不唯一导致的解锁准确度不高的问题,能够提高语音解锁的准确度。另外,由于需要填入密码的第二类字符在解码字符串中的位置是不固定的,因此,密码不易被盗取,提高了语音解锁的安全性。
实施例1:
本发明实施例提供一种终端,如图1所示,所述终端包括:显示面板101、麦克风102、处理器103以及存储器104。
显示面板101,用于在所述终端的锁屏界面随机显示一串文本字符,所述文本字符包括第一类字符和第二类字符;其中,所述第二类字符用于指示待输入密码字符在所述文本字符中的位置,所述第一类字符和所述待输入密码字符组成解锁所述终端的密码字符串。
这里,第一类字符可以是数字和/或字母,其中,数字可以是0~9,字母可以是英文字母,也可以是声母、韵母等,在此不作限定。第二类字符可以是“_”“*”等,提示语音解锁时需要在第二类字符对应的位置填入密码。这里的“填入”并非用户手动输入,而是用户在阅读解锁字符串时需要以发声形式填入。示例的,参考图2,显示面板101显示的文本字符可以是为“23_8_9_0”,即指示用户在3和8之间、8和9之间以及9和0之间三处填入密码。若用户填入的密码为abc,那么用户阅读“23a8b9c0”。
另外,处理器103需要在显示面板101在所述终端的锁屏界面
随机显示一串文本字符之前根据第一类字符与所述待输入密码字符生成所述密码字符串。其中,所述待输入密码字符即为用户预设的密码。若终端真实用户预先设置的文本密码即所述待输入密码为269,则所述密码字符串为“23286990”,即所述待输入密码在所述密码字符串中的位置与所述第二类字符在所述文本字符中的位置相同。
麦克风102,用于接收语音信息。
需要说明的是,这里的用户是本次解锁欲使用所述终端的用户,可以是所述终端的真实用户,也可以是其他用户,在此不作限定。具体实现中,用户按照显示面板101显示的解锁字符串依次阅读。参考图2,若用户在3和8之间、8和9之间以及9和0之间依次填入的密码为abc,那么用户阅读“23a8b9c0”。
另外,第二类字符在文本字符中的位置是随机的。虽然预设密码字符串不变,但用户阅读时插入的密码字符的位置是随机的,因此,旁听者无法盗听到真实的预设密码字符串。提高了语音解锁的安全性。
处理器103,用于在所述语音信息中识别出解锁字符串。判断所述解锁字符串与所述密码字符串是否匹配,若所述解锁字符串与所述密码字符串匹配,解析所述语音信息,获取所述语音信息的声纹。
也就是说,判断用户在第二类字符对应的位置填入的密码是否正确以及用户阅读的第一类字符是否正确,承上所述,若用户预设的密码即所述待输入密码字符为abc,用户阅读的是“23a8b9c0”,即在第二类字符对应的位置填入的密码是正确的,因此可以进一步去获取所述语音信息的声纹,即该用户的声纹。
另外,需要说明的是,所述待输入密码字符可以与显示的第一类字符包括相同的字符,也可以不包括相同字符,在此不作限定。
所述处理器103还用于,判断所述语音信息的声纹与预设声纹是否相同;所述预设声纹是根据所述预设字符集合获得的;若判断
所述所述语音信息的声纹与预设声纹相同,则解锁。
需要说明的是,所述预设声纹是所述终端的真实用户预先阅读所述预设字符集合中的每一个字符后,所述终端根据录音获得的所述终端的真实用户的声纹。若所述语音信息的声纹与所述预设声纹相同,则表明本次解锁的用户与所述终端的真实用户是同一用户,因此可以解锁。
所述处理器103还用于,在所述锁屏界面随机显示一串文本字符之前,接收设置指令;在接收所述设置指令之后,生成所述预设字符集合。
这里,用户在设置页面选中声纹设置功能按钮,终端检测到声纹设置按钮为开启状态,则生成设置指令,指示需要设置声纹,处理器103则会接收到该设置指令。进而生成预设字符集合。
所述显示面板101还用于,显示训练字符串,所述训练字符串包括预设字符集合的所有字符。具体实现中,可以参考图3所示的方式来显示所述训练字符串,即将所述训练字符串依次排列显示显示面板,指示用户依次阅读每一个字符。当然,不限定字符的排列顺序,可以随机排列。示例的,参考图3,提示用户“请至少阅读三遍以下字符--0123456789”,其中“0123456789”即训练字符串。或者,可以提醒用户分次阅读训练字符串,每次阅读的训练字符串可以不同,但均由预设字符集合的所有字符构成。示例的,提示用户依次阅读“0123456789”、“2468975013”、“9013765248”。
所述麦克风102还用于,接收训练语音信息,所述训练语音信息指示用户阅读的所述训练字符串。具体实现中,用户可以多次(如:至少三次)阅读所述训练字符串,以便准确提取用户的声纹。
所述处理器103还用于,解析所述训练语音信息,获得所述预设声纹。
所述处理器103具体用于,判断所述解锁字符串与所述密码字符串包括的字符是否相同;若所述解锁字符串与所述密码字符串包括的字符相同,则判断每一个字符在所述解锁字符串中的位置与在
所述密码字符串中的位置是否相同;若每一个字符在所述解锁字符串中的位置与在所述密码字符串中的位置相同,则确定所述解锁字符串与所述密码字符串匹配。
也就是说,用户阅读的解锁字符串必须与所述密码字符串一一对应,才能认为解锁字符串与所述密码字符串匹配。示例的,预设的密码字符串为1268,只有用户阅读的字符依次为1268,才能确定所述解锁字符串与预设的密码字符串匹配,若用户阅读的字符依次为1682或2861,则不能认为所述解锁字符串与所述密码字符串匹配。
所述处理器103还用于,在所述显示面板101随机显示文本字符之前,控制所述终端进入锁定状态,接收解锁指令。
具体实现中,若处理器103检测到终端在预设时长(如:1分钟)内未被操作,则控制所述终端进入锁定状态。这里的接收解锁指令,可以是终端的某个外设按键被按中,或者终端显示面板101被点亮。
另外,所述终端还包括提示器,若所述处理器确定所述N个密码字符与预设密码字符串不匹配,提示解锁失败。
需要说明的是,所述提示器可以是显示面板101或终端的扬声器,具体地,可以是显示面板显示文字提示解锁失败,或是终端的扬声器播放语音提示解锁失败。
所述提示器还用于,若所述判断单元确定所述语音信息的声纹与预设声纹不相同,则提示解锁失败。
进一步地,所述扬声器还用于,在所述显示面板101在所述终端的锁屏界面随机显示一串文本字符之后,提示用户语音输入所述解锁字符串。可以是通过语音提示用户阅读解锁界面显示的第一类字符并在第二类字符所在位置填入密码,语音输入所述解锁字符串。
或,所述显示面板101用于,在所述终端的锁屏界面随机显示一串文本字符之后,提示用户语音输入所述解锁字符串。可以在解锁界面显示文本文字,提示用户语音输入所述解锁字符串,如在解
锁界面显示“请阅读已显示的数字同时在未显示数字处填入密码”。
需要说明的是,终端10可以为手机、平板电脑、笔记本电脑、UMPC(Ultra-mobile Personal Computer,超级移动个人计算机)、上网本、PDA(Personal Digital Assistant,个人数字助理)等终端设备,
下面结合图1对终端10的各个构成部件进行具体的介绍:
显示面板101,可选的,可以采用LCD(Liquid Crystal Display,液晶显示器)、OLED(Organic Light-Emitting Diode,有机发光二极管)等形式来配置。
麦克风102将收集的声音信号(如:用户阅读的解锁字符串或训练字符串)转换为音频数据,传输出至处理器101以便进一步处理,如:麦克风102接收用户阅读的所述语音信息,在音频数据中确定第二类字符对应的音频数据,将这些音频数据转化为文本信息,在判断这些文本信息与预设密码字符串是否匹配。
处理器103是终端10的控制中心,利用各种接口和线路连接整个终端的各个部分,通过运行或执行存储在存储器104内的软件程序和/或模块,以及调用存储在存储器104内的数据,执行终端10的各种功能和处理数据,从而对终端进行整体监控。可选的,处理器380可包括一个或多个处理单元;优选的,处理器103可集成应用处理器和调制解调处理器,其中,应用处理器主要处理操作系统、用户界面和应用程序等,调制解调处理器主要处理无线通信。可以理解的是,上述调制解调处理器也可以不集成到处理器103中。
存储器104可用于存储软件程序以及模块,处理器103通过运行存储在存储器104的软件程序以及模块,从而执行终端10的各种功能应用以及数据处理。存储器104可主要包括存储程序区和存储数据区,其中,存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等;存储数据区可存储根据终端10的使用所创建的数据(比如音频数据、图像数据、电话本等)等。此外,存储器104可以包括高速随机存取存储器,还可以包括非易失性存储器,例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
尽管未示出,终端10还包括给各个部件供电的电源(比如电池),优选的,电源可以通过电源管理系统与处理器103逻辑相连,从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
终端10还可以包括WiFi(wireless fidelity,无线保真)模块、蓝牙模块等,在此不再赘述。
本发明提供的终端,随机显示解锁字符串,随机显示包括第一类字符与第二类字符的文本字符,第二类字符用于指示待输入密码的位置。用户阅读时需要在第二类字符所在位置填入密码,终端解析用户输入的语音信息获得解锁字符串,解锁字符串与密码字符串匹配且语音信息的声纹识别通过后,才能够解锁。现有语音解锁仅仅依靠声纹进行识别,由于目前技术提取的声纹不具备唯一性,导致目前的语音解锁方案准确度不高,同时导致安全性降低。本发明将文本密码与声纹识别结合在一起,避免声纹不唯一导致的解锁准确度不高的问题,能够提高语音解锁的准确度。另外,由于需要填入密码的第二类字符在解锁界面显示的文本字符中的位置是随机的,因此,密码不易被盗取,提高了语音解锁的安全性。
实施例2:
本发明实施例提供一种解锁设置方法,应用于图1所示的终端,如图4所示,所述方法包括以下步骤:
201、终端接收设置指令,生成预设字符集合。
202、所述终端显示训练字符串,所述训练字符串包括所述预设字符集合的所有字符。
203、所述终端接收训练语音信息,所述训练语音信息指示用户阅读的所述训练字符串。
具体实现中,终端对用户语音进行录音,获取到所述训练语音信息。
204、所述终端判断录音次数是否大于X。
这里的X可以是任意一个数值,是由用户设置的或是终端出厂时预设置的。
若录音次数不大于所述X,则进行步骤202;若录音次数大于所
述X,则进行步骤205。
205、所述终端解析所述训练语音信息,获取预设声纹。
所述预设声纹,即所述终端的真实用户的声纹。
206、所述终端提示用户设置预设密码字符串。
具体地,可以将所述预设字符集合中的所有字符显示在终端的显示面板,以便用户在其中选中预设密码字符串。示例的,参考图5,终端显示的字符可以是1569dpqk,用户依次选中“6pk”,则终端确认用户设置的预设密码字符串为“6pk”。具体实现中,用户点击某字符对应在显示面板上的位置,即认为用户选中了该字符。进一步地,为了明确用户选中的字符的顺序,还可以将用户选中的预设密码字符串显示在显示面板,提示用户是否确认该预设密码字符串。示例的,参考图6,提示用户预设密码字符串为“6pk”,可以选择确认或重设。
基于上述解锁设置方法,本发明实施例提供一种终端的语音解锁方法,如图7所示,所述方法包括以下步骤:
301、所述终端生成第一类字符,根据所述第一类字符和待输入密码字符构成密码字符串。
在此,待输入密码字符是用户预先设定的文本密码,其所在位置与所述第二类字符所在位置相同。示例的,第二类字符为“_”且位置如是:“23_8_9_0”,假定用户预设的密码字符即所述待输入密码字符为abc,那么构成的密码字符串为“23a8b9c0”。
需要说明的是,待输入密码字符与随机显示的第一类字符可以相同,也可以不同,在此不作限定。
302、在所述终端的锁屏界面随机显示一串文本字符,所述文本字符包括第一类字符和第二类字符。
其中,所述第二类字符用于指示待输入密码字符在所述文本字符中的位置,所述第一类字符和所述待输入密码字符组成解锁所述终端的密码字符串。具体实现中,可以显示M个第一类字符和N个第二类字符,提示用户阅读时除了M个第一类字符外,还需要在N个第二类字符所在位置填入N个密码。所述第一类字符属于预设字
符集合,所述第二类字符不属于所述预设字符集合。
另外,这里,第一类字符可以是数字、字母等,第二类字符可以是“_”“*”等,提示语音解锁时需要在第二类字符对应的位置填入密码。示例的,解锁字符串为“23_8_9_0”,即指示用户在3和8之间、8和9之间以及9和0之间三处填入密码。若用户填入的密码为abc,那么用户阅读“23a8b9c0”。
当然,在步骤302之后,终端还可以提示用户输入所述解锁字符串。
具体实现中,可以是通过语音提示用户阅读解锁界面显示的第一类字符并在第二类字符所在位置填入密码,语音输入所述解锁字符串。当然也可以在解锁界面显示文本文字,提示用户语音输入所述解锁字符串,如在解锁界面显示“请阅读已显示的数字同时在未显示数字处填入密码”。
303、所述终端接收语音信息,从所述语音信息中识别出解锁字符串。
具体实现中,即对用户依次阅读的所述第二类字符对应的密码和第一类字符进行录音。
当然,由于用户按照终端解锁界面显示的文本字符的顺序阅读所述第一类字符,同时在第二类字符所在位置语音填入的密码,那么所述语音信息同时指示了所述第一类字符和用户语音输入的密码的相对顺序。
304、所述终端判断所述解锁字符串与所述密码字符串是否匹配。
具体实现中,判断所述解锁字符串与所述密码字符串包括的字符是否相同;若所述解锁字符串与所述密码字符串包括的字符相同,则判断每一个字符在所述解锁字符串中的位置与在所述密码字符串中的位置是否相同;若每一个字符在所述解锁字符串中的位置与在所述密码字符串中的位置相同,则确定所述解锁字符串与所述密码字符串匹配。
也就是说,用户阅读的解锁字符串必须与预设的密码字符串包
括的字符一一对应,才能认为解锁字符串与所述预设密码字符串匹配。
若所述解锁字符串与所述密码字符串不匹配,则进行步骤306;若所述N个密码字符与预设密码字符串匹配,则进行步骤304。
305、所述终端则解析所述语音信息,获取所述语音信息的声纹,判断所述所述语音信息的声纹与预设声纹是否相同。
其中,所述预设声纹是根据所述预设字符集合获得的,即终端用户预先阅读所述预设字符集合的每一个字符,终端根据录音获取预设声纹。
若所述所述语音信息的声纹与预设声纹是否相同,则进行步骤306;若所述所述语音信息的声纹与预设声纹不相同,则进行步骤307。
306、终端进行解锁。
307、所述终端提示解锁失败。
具体地,可以在终端显示面板的特定区域显示文本——“解锁失败”。或者,通过扬声器播放语音提示解锁失败。
当然,终端提示解锁失败后,还可以再次随机显示一个解锁字符串。
本发明提供的方法,随机显示包括第一类字符与第二类字符的文本字符,第二类字符用于指示待输入密码的位置。用户阅读时需要在第二类字符所在位置填入密码,终端解析用户输入的语音信息获得解锁字符串,解锁字符串与密码字符串匹配且语音信息的声纹识别通过后,才能够解锁。现有语音解锁仅仅依靠声纹进行识别,由于目前技术提取的声纹不具备唯一性,导致目前的语音解锁方案准确度不高,同时导致安全性降低。本发明将文本密码与声纹识别结合在一起,避免声纹不唯一导致的解锁准确度不高的问题,能够提高语音解锁的准确度。另外,由于指示填入密码的第二类字符在解锁界面显示的文本字符中的位置是随机的,因此,密码不易被盗取,提高了语音解锁的安全性。

如图11所示,所述终端40还包括锁定单元409、提示单元410。
