而检测到有输入或者输出音频信号, 则继续判断所检测到的输入或输出 音频信号的频率和 /或强度是否属于人声范围内, 若所检测到的所有音频信号 的频率和 /或强度在设定时长内均超出人声范围, 则确定本移动终端处于闲置 通话状态。
针对上述检测移动终端是否处于闲置通话状态的方式, 需要进一步予以 以下说明:
目前普通人能够听到的声波的频率范围为 20HZ--20KHZ, 低于 20HZ为 次声波, 超过 20KZ为超声波。 人说话的声音范围只在人能够听到的声音范 围中占较窄的一部分, 一般在 100HZ-—- 8KHZ以内, 而 200~4000HZ被称为 人声基频, 大部分人说话的频率都在该范围内, 很多乐器的频率范围与人声 的范围有重叠, 但是生活中的大部分环境噪音从频率分析上可以将其与人声 音分开, 例如炒菜, 碰撞等。 而人耳则对 3KHZ附近的音频感觉最为敏锐。 故可以通过检测到的输入或者输出音频信号的频率是否属于人声范围内来确 定当前的语音通话是否为正常用户间的语音交流。 也就是说, 输入和输出音 频信号均的频率均不在人声范围内时, 认为此为异常通话状态即移动终端处 于闲置通话状态。
另一方面, 从声音的强度上也能够将人声与环境噪音区分开来, 一般来 说, 当人对着电话说话时, 麦克感受到的人声音强度要远远大于环境噪音的 强度, 正常人通话中的声音强度大约在 30〜: lOOdB 范围, 普通交谈大约在 60~70dB,如果手机检测到双方长时间接收到的声音都小于正常人说话时的声 音强度, 则可以认为有可能处于闲置通话状态, 从而给用户提示甚至挂断电 话。
而从环境中简单检测是否有人声输入是声音处理领域中的一项已有技 术, 但目前还没有应用在手机语音通话处理中的在先实例。
而基于上述以音频和强度为依据判断是否有人声输入的原理, 可以优选 地, 将音频信号的频率检测作为主要判断依据, 而音频信号的强度检测则为 辅助判断依据。 也就是说, 主要检测音频信号的频率是否属于人声范围来判 断移动终端的状态, 次要检测音频信号的强度来辅助判断移动终端是否处于 闲置通话状态。 即一旦检测到音频信号的频率超出人声范围即可判断移动终 端处于闲置通话状态。 而检测到音频信号的频率未超出人声范围时, 可进一 步通过音频信号的强度来判断移动终端是否处于闲置通话状态。
另外, 检测本移动终端是否处于闲置通话状态的方式还可以是: 在语音 通话过程中, 移动终端中重力传感器实时检测本移动终端的 X、 Υ、 Ζ值, 若 所检测到的 X、 Υ、 Ζ值在设定时长内未发生变化, 才检测本移动终端是否处 于闲置通话状态。
而上述通过重力传感器检测移动终端是否处于闲置通话状态的原理是: 在通话启动后, 手机每隔预定时间对比一次重力传感器检测到的 Χ,Υ,Ζ值。 重力传感器的 X, Υ, Ζ数值如果在一个设定时长内 (如上述时间阔值一)没 有发生变化, 认为用户已经将手机放下, 并未处于握机通话状态, 即移动终 端处于闲置通话状态。 需要说明的是, 本实施例中重力传感器的 X, Υ, Ζ数 值没有发生变化指, 在设定时长内 X, Υ, Ζ数值的变化均在一个允许的变化 范围内, 即轻微的变动, 比如现有的传感器 xyz允许的变化范围为 (0.114, -0.191,9.845 ) , 仅仅是小数点后第 2、 3位变动(这个可能是由于环境中的振 动引发的) 。 具体地, 重力传感器的工作原理一般为: 由于内部晶体的形变 产生电压信号, 并形成电压输出传递给移动终端的信号处理模块。
还要说明的是, 为了减少误判的情况, 可以将上述通过输入语音的音频 和 /或强度, 以及重力传感器来确定移动终端是否处于闲置通话状态的方式进 行结合, 即先通过重力传感器来判断用户是握机进行通话, 还是已将移动终 端放下, 当确定用户已将移动终端放下时, 再进一步通过对输入语音的音频 / 或强度判断, 来判断移动终端是否真的处于闲置通话状态。
针对移动终端有重力传感器的情况下, 可通过运动状态对异常通话进行 异常通话的处理过程, 该过程如图 1所示, 包括:
步骤 S102: 移动终端正在通话中, 用户 (或终端默认)开启了异常通话 提示功能。 步骤 S104: 语音通话开启后, 加速传感器同步启动, 并将压电信号传输 给信号处理器进行处理。
步骤 S106: 信号处理器将信号值转换为移动终端的三维坐标值 XYZ。 步骤 S108: 周期性的计算前后两个坐标点的距离 (或者大小) , 如果距 离为 0或者大小差距非常小,则判断移动终端处于静置状态,启动计时器 Tl。
步骤 S110: 累计的时间超过时间阔值一。
其中,在 T1值未超过时间阔值一的时间段内, 突然出现连续几个坐标点 与前一个坐标点差距很大时, 要将该 T1值清零。 步骤 S112: 移动终端按照事先设置的提示方式(例如以声音、 振动、 图 片、 视频等形式组合)对用户进行提示。
步骤 S114: 移动终端检测在时间阔值二内, 是否收到用户发起的结束语 音通话的操作指令(包括对手机触摸屏或键盘进行的操作) , 如果是, 返回 步骤 S102; 否则转入步骤 S116。
步骤 S116: 手机强制结束通话。
图 2所示为通过音频输入对异常通话进行处理的具体过程,该过程包括: 步骤 S202: 移动终端正在通话中, 用户 (或终端默认)开启了异常通话 提示功能。
步骤 S204: 语音通话开启后, 语音识别模块同步自动启用, 并从语音编 码模块获取通话双方输入的音频。
步骤 S206: 语音识别模块分别提取双方通话的实时频谱和声强, 发送给 判断模块。
步骤 S208: 判断模块周期性判断音频的频谱是否处于正常的人声频谱范 围, 并辅助判断强度是否是正常通话强度, 如果频谱与声音强度二者都不符 合人声通话的特性, 则判断移动终端处于静置状态, 启动计时器 T2。
步骤 S210: 累计的时间超过时间阔值一。
其中, Τ2值未超过时间阔值一的时间段内, 判断模块继续周期性的检测 音频输入是否符合人声特性, 当在累计超时之前收到了通话输入时, 要将 Τ2 值清零。
步骤 S212: 移动终端按照事先设置的提示方式(例如以声音、 振动、 图 片、 视频等形式组合)对用户进行提示。
步骤 S214: 移动终端检测在时间阔值二内, 是否收到用户发起的结束语 音通话的操作指令(包括对手机触摸屏或键盘进行的操作) , 如果是, 返回 步骤 S202; 否则转入步骤 S216。
步骤 S216: 手机强制结束通话。
若同时结合上述运行状态及音频输入方式来对异常通话进行处理时, 该 处理过程如图 3所示, 包括:
步骤 S302: 移动终端正在通话中, 用户 (或终端默认)开启了异常通话 提示功能。
步骤 S304: 语音通话开启后, 加速传感器同步启动, 并将压电信号传输 给信号处理器进行处理, 信号处理器将信号值转换为移动终端的三维坐标值 XYZ, 并将数值传递至判断模块。
步骤 S306: 判断模块周期性的计算前后两个坐标点的距离或者大小, 如 果距离为 0或者大小差距非常小, 则判断移动终端处于静置状态, 启动计时 器 T31。
步骤 S308: T31累计的时间超过时间阔值一。
该步骤中, 在 T31值未超过时间阔值一的时间段内, 如果突然出现连续 几个坐标点与前一个坐标点差距很大时, 则要将该 T31值清零, 并返回步骤 306。
步骤 S310: 语音识别模块自动启用, 并从语音编码模块获取通话双方输 入的音频。 语音识别模块对比双方的语音输入, 将通话双方的音频频谱及强 度等特征传递给判断模块。
步骤 S312: 判断模块根据人声的频谱和强度等的特征范围, 周期性判断 通话双方音频是否都已经没有了人声输入, 如果确认双方都没有通话输入, 则判断移动终端可能处于静置状态, 启动计时器 Τ32。
步骤 S314: Τ32的累计时间超过时间阔值一。 该步骤中, 在 T21值未超过时间阔值一的时间段内, 如果判断模块继续 周期性的检测音频输入是否符合人声特性, 当在累计超时之前收到了通话输 入时, 则要将 T2值清零, 并返回步骤 306。
步骤 S316: 移动终端按照事先设置的提示方式(例如以声音、 振动、 图 片、 视频等形式组合)对用户进行提示。
步骤 S318: 移动终端检测在时间阔值二内, 是否收到用户发起的结束语 音通话的操作指令(包括对手机触摸屏或键盘进行的操作) , 如果是, 返回 步骤 S302; 否则转入步骤 S320。
步骤 S320: 手机强制结束通话。
实施例 2
本实施例介绍一种移动终端, 该终端至少包括:
检测单元, 在语音通话过程中,检测本移动终端是否处于闲置通话状态, 并在检测出本移动终端处于闲置通话状态时, 通知所述语音通话模块本移动 终端处于闲置通话状态;
语音通话模块, 在收到本移动终端处于闲置通话状态的通知时, 按照事 先设定设置的方式提示用户本次语音通话已结束, 或者直接挂断本次语音通 话, 或者先提示用户本次语音通话已结束再挂断本次语音通话。 需要说明的 是, 本实施例中语音通话模块增加了异常通话提示功能。
而语音通话模块, 先提示用户本次语音通话已结束再挂断本次语音通话 的具体过程是, 在按照事先设置的方式提示用户本次语音通话已结束后, 还 可以判断设定时长内或提示次数达到设定值时, 是否收到结束语音通话操作 指令, 如果均未收到, 则挂断本次语音通话。
上述检测单元可以包括语音识别模块和判断模块。
语音识别模块, 在语音通话过程中, 实时检测输入和输出音频信号; 判断模块, 在所述语音识别模块在设定时长内均未检测到输入和输出音 频信号时, 确定本移动终端处于闲置通话状态。
具体地, 手机中预置有语音识别模块。 在通话过程中, 语音识别模块对 通话本机输入音频 (即输出音频信号)和网络传过来的对方的语音输入(即 输入音频信号)进行判断, 检测对方和本机是否都有声音输入, 或者所检测 到的音频信号的频率是否与人声音的频率范围对应。 所检测到的音频信号的 强度是否是正常的人声范围, 如果在较长的时间内 (如上述时间阔值一)语 音输入模块判断双方都没有任何语音输入(即均检测不到输入音频信号和输 出音频信号) , 则可以认为双方已经结束了通话但是没有及时挂断。
另一些方案中, 上述语音识别模块, 在检测到输入或者输出音频信号时, 还检测所检测到的输入或输出音频信号的频率和 /或强度。 此时, 判断模块, 在语音识别模块检测出所检测到的所有音频信号的频率和 /或强度在设定时 长内均超出人声范围时, 确定本移动终端处于闲置通话状态。
另外, 优选方案中, 考虑到用户手握手机通话时, 通常在一定时间内会 走动或变换姿势, 因此移动终端可以加装重力传感器的以判断用户是否正在 处于通话中。 具体地, 重力传感器在语音通话过程中, 实时检测本移动终端 的 X、 Υ、 Ζ值。 而检测单元, 在重力传感器所检测到的 X、 Υ、 Ζ值在设定 时长内未发生变化时, 才检测本移动终端是否处于闲置通话状态。
当然上述检测单元也可以只包括重力传感器和判断模块。 其中, 重力传 感器, 在语音通话过程中, 实时检测本移动终端的 X、 Υ、 Ζ值; 而判断模块, 在重力传感器检测到的 X、 Υ、 Ζ值在设定时长内未发生变化时, 即可确定本 移动终端处于闲置通话状态。
上述通过检测移动终端运动状态或音频输入, 确定手机是否在闲置异常 通话状态, 并对用户进行提示。 实际上, 本发明中提到的方法, 也可以通过 其他方式进行, 如检测是人体接近传感器, 红外等方式, 其实现的原理与上 述两种方式没有明显的区别, 此处不再赘述。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序 来指令相关硬件完成, 所述程序可以存储于计算机可读存储介质中, 如只读 存储器、 磁盘或光盘等。 可选地, 上述实施例的全部或部分步骤也可以使用 一个或多个集成电路来实现。 相应地, 上述实施例中的各模块 /单元可以釆用 硬件的形式实现, 也可以釆用软件功能模块的形式实现。 本申请不限制于任 何特定形式的硬件和软件的结合。
以上所述, 仅为本发明的较佳实例而已, 并非用于限定本发明的保护范 围。 凡在本发明的精神和原则之内, 所做的任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
工业实用性 本发明实施例只需要对移动终端做较小的改动就可以达到预期的效果, 不需要做大规模的软件和硬件变更。
