下面将结合本公开的实施例中的附图， 对本公开的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公开的一部分实施 例， 而不是全部的实施例。 基于本公开中的实施例， 本领域普通技术人员在 没有做出创造性劳动前提下所获得的所有其他实施例， 都属于本公开保护的 范围。
本公开的实施例提供一种语音控制电视机的方法， 如图 1 所示， 用于电 视机， 包括：
步骤 101， 釆集用户的第一语音信号。
电视机在接受用户语音控制时， 首先需要接收用户的语音指令， 该语音 指令即为电视机需要釆集的第一语音信号。 由于电视机的用户发出的语音命 令可以是任何一种语言或任何一种方言， 所以电视机釆集到的第一语音信号 也可以是任意一种语言或者任意一种方言。
步骤 102， 当所述电视机无法识别所述第一语音信号时， 显示指令界面， 所述指令界面包括 N个指令， 以便于所述用户选择与所述第一语音信号相对 应的第一指令， 所述第一指令为所述 N个指令中任意一个指令。
例如， 电视机釆集到第一语音信号之后， 首先判断所述电视机能否识别 出第一语音信号， 所述对第一语音信号的语音识别与已知的技术的语音识别 过程一样， 本公开的实施例对此不做赞述。 当所述电视机无法识别所述第一 语音信号时， 该电视机就无法进行用户的语音控制过程， 这时该电视机显示 指令界面， 所述指令界面可以显示 N个指令， 所述 N个指令是所述电视机的 所有可执行的指令， 实际应用中指令界面也可以显示所述电视机根据所述第 一语音信号进行筛选得出的 M个用户可能需要的指令，所述 M小于或等于 N。 用户在该指令界面所显示的 N个指令中选择所需的第一指令， 所述第一指令 为所述 N个指令中的任意一个指令， 通常的， 用户可以利用遥控器将待确认 标识移动到所述第一指令， 然后通过确认键选择第一指令， 也可以在初始化 时为电视机的所有可执行指令编号， 然后用户通过利用遥控器的数字按键选 择第一指令对应的编号来选择第一指令。
步骤 103， 根据预先建立的指令 -语音组对应关系， 将所述第一语音信号 保存在所述第一指令对应的第一语音组中， 所述第一语音组中包括触发第一 指令的所有语音信号。
所述指令 -语音组对应关系是预先建立的，用于指示所述 N个指令与 N个 语音组的对应关系， 使得所述 N个指令中的每个指令对应一个语音组， 每个 语音组中包括能够触发该语音组对应的指令的所有语音信号。 当用户选择的 指令为第一指令时， 说明电视机釆集到的第一语音信号所对应的指令为第一 指令， 电视机执行第一指令， 并根据预先建立的指令 -语音组对应关系， 将所 述第一语音信号保存在第一指令对应的第一语音组中， 该第一语音组中包括 能够触发第一指令的所有语音信号， 当下次进行语音控制时， 若用户的语音 指令为第一语音信号， 则电视机能够识别出用户需要进行第一指令的操作， 并在识别之后执行第一指令， 完成用户的语音控制过程。
这样一来， 当电视机无法识别釆集到的第一语音信号， 即电视机无法识 别用户的语音指令时， 能够显示指令界面， 该指令界面包括 N个指令， 用户 可以根据需要选择需要电视机执行的第一指令， 然后电视机执行第一指令， 并根据预先建立的指令-语音组对应关系， 将第一语音信号保存在第一指令对 应的第一语音组中， 以便于用户再次通过第一语音信号触发第一指令， 相较 于已知的技术， 完善了电视机的语音控制功能。
例如， 在所述釆集用户的第一语音信号之前， 该电视机还需要建立所述 指令 -语音组对应关系，所述指令 -语音组对应关系用于指示所述 N个指令与 N 个语音组的对应关系， 使得所述 N个指令中的每个指令对应一个语音组。 示 例的， 假设 N为 4， 该 4个指令分别为 "播放"、 "暂停"、 "快进"和 "快退"， 若 "播放" 为第一指令， 对应的语音组为第一语音组， 第一语音组中包括 M 个语音信号， 则当用户进行语音控制时， 电视机釆集到的语音信号为该 M个 语音信号中的任意一个语音信号， 均可触发电视机执行播放的动作。
可选地， 在初始化时， 可以为电视机的 N个可执行指令录制标准语音信 号， 该电视机的指令对应的 N个语音组中每个语音组中包括标准语音信号， 即任意一个指令所对应的语音组中包括一个能够触发该指令的标准语音信 号， 通常情况下， 所述标准语音信号是由标准普通话录制生成的。
可选地， 在所述釆集用户的第一语音信号之前， 还可以为所述 N个指令 进行编号， 使得每个所述指令对应一个数字， 以便于所述用户根据所述数字， 选择对应的指令。
本公开的实施例提供的语音控制电视机的方法， 首先釆集用户的第一语 音信号， 然后判断能否识别该第一语音信号， 当所述电视机无法识别所述第 一语音信号时， 显示指令界面， 所述指令界面包括 N个指令， 以便于所述用 户选择与所述第一语音信号相对应的第一指令， 所述第一指令为所述 N个指 令中任意一个指令， 当用户选择第一指令之后， 执行该第一指令并根据预先 建立的指令 -语音组对应关系， 将第一语音信号保存在第一指令对应的第一语 音组中， 当下次用户的语音指令为第一语音信号时， 电视机能够识别出用户 需要进行第一指令的操作， 并在识别之后执行第一指令， 完成用户的语音控 制过程， 相较于已知的技术， 完善了电视机的语音控制功能。
本公开的实施例提供一种语音控制电视机的方法， 如图 2所示， 包括： 步骤 201， 获取电视机的 N个指令， 执行步骤 202。
随着电视机的发展， 通常情况下， 电视机可以执行的指令也越来越多， 因此首先需要获取电视机可以执行的 N个指令。
步骤 202， 建立指令 -语音组对应关系， 所述指令 -语音组对应关系用于指 示所述 N个指令与 N个语音组的对应关系，使得所述 N个指令中的每个指令 对应一个语音组， 执行步骤 203。
在获取到电视机的 N个指令之后，电视机需要为所述 N个指令设置 N个 语音组， 并建立指令 -语音组对应关系， 所述指令-语音组对应关系用于指示所 述 N个指令与 N个语音组的对应关系，使得所述 N个指令中的每个指令对应 一个语音组， 每个语音组中包括所有能够触发该语音组对应的指令的语音信 号。 示例的， 假设 N为 4， 该 4个指令分别为 "播放"、 "暂停"、 "快进" 和 "快退"， 则电视机需要设置 4个语音组， 分别对应 4个指令， 例如， 若 "播 放" 为第一指令， 对应的语音组为第一语音组， 第一语音组中包括 M个语音 信号， 则当用户进行语音控制时， 电视机釆集到的语音信号为该 M个语音信 号中的任意一个语音信号， 均可触发电视机执行播放的动作。
步骤 203， 为 N个语音组中的每个语音组录制标准语音信号， 执行步骤 204。
例如， 可以为所述 N个语音组中的每个语音组录制标准语音信号， 例如， 用普通话录制第一标准语音信号， 并将该第一标准语音信号保存在第一语音 组， 这样一来， 当用户用普通话输入语音指令时， 该电视机能够识别用户的 语音指令， 并能根据该语音指令执行对应的第一指令。
步骤 204， 釆集用户的第一语音信号， 执行步骤 205。
电视机在接受用户语音控制时， 首先需要接收用户的语音指令， 该语音 指令即为电视机需要釆集的第一语音信号。 由于电视机的用户发出的语音命 令可以是任何一种语言或任何一种方言， 所以电视机釆集到的第一语音信号 也可以是任意一种语言或者任意一种方言。
步骤 205，判断是否能够识别所述第一语音信号， 当电视机无法识别该第 一语音信号时， 执行步骤 206; 当电视机能够识别该第一语音信号时， 执行步 骤 208。
通常的， 电视机釆集到第一语音信号之后， 对第一语音信号进行语音识 另1 J， 示例的， 可以通过芯片 LD3320、 芯片 ASR M08等语音识别芯片对第一 语音信号进行语音识别， 所述语音识别的过程与已知的技术相同， 本公开实 施例对此不作详述。
步骤 206，显示指令界面， 以便于所述用户选择与所述第一语音信号相对 应的第一指令， 所述指令界面包括 N个指令， 执行步骤 207。
当电视机无法识别釆集到的第一语音信号时， 可以显示指令界面， 所述 指令界面可以显示 N个指令， 所述 N个指令是所述电视机的所有可执行的指 令， 实际应用中指令界面也可以显示所述电视机根据所述第一语音信号进行 筛选得出的 M个用户可能需要的指令， 所述 M小于或等于 N。用户可以在该 指令界面所显示的 N个指令中选择所需的第一指令， 所述第一指令为所述 N 个指令中的任意一个指令， 通常的， 用户可以利用遥控器将待确认标识移动 到所述第一指令， 然后通过确认键选择第一指令， 也可以在初始化时为电视 机的所有可执行指令编号， 然后用户通过利用遥控器的数字按键选择第一指 令对应的编号来选择第一指令。
例如， 假设 N为 4， 该 4个指令分别为 "播放"、 "暂停"、 "快进"和 "快 退"， 则指令界面显示 "播放"、 "暂停"、 "快进" 和 "快退" 这四个指令， 以 便于用户选择与所述第一语音信号相对应的第一指令， 假设第一语音信号对 应的第一指令为 "播放"。
步骤 207， 根据预先建立的指令 -语音组对应关系， 将所述第一语音信号 保存在所述第一指令对应的第一语音组中， 所述第一语音组中包括触发第一 指令的所有语音信号， 执行步骤 208。
当用户选择的指令为第一指令时， 说明电视机釆集到的第一语音信号所 对应的指令为第一指令， 电视机将所述第一语音信号保存在第一指令对应的 第一语音组中， 该第一语音组中包括能够触发第一指令的所有语音信号， 当 下次用户的语音指令为第一语音信号时， 电视机能够识别出用户需要进行第 一指令的操作， 并在识别之后执行第一指令， 完成用户的语音控制过程。 例 如， 当用户选择的第一指令为 "播放" 时， 说明第一语音信号对应的指令为 "播放"， 电视机将釆集到的第一语音信号保存在指令 "播放" 对应的语音组 中， 当下次进行语音控制时， 若用户的语音指令为第一语音信号， 电视机能 够识别并执行指令 "播放"。
步骤 208， 执行第一指令。
例如， 当电视机能够识别釆集到的第一语音信号时， 可以执行该第一语 音信号对应的第一指令。
本公开的实施例提供的语音控制电视机的方法， 首先釆集用户的第一语 音信号， 然后判断能否识别该第一语音信号， 当所述电视机无法识别所述第 一语音信号时， 显示指令界面， 所述指令界面包括 N个指令， 以便于所述用 户选择与所述第一语音信号相对应的第一指令， 所述第一指令为所述 N个指 令中任意一个指令， 当用户选择第一指令之后， 执行该第一指令并根据预先 建立的指令-语音组对应关系， 将第一语音信号保存在第一指令对应的第一语 音组中， 当下次用户的语音指令为第一语音信号时， 电视机能够识别出用户 需要进行第一指令的操作， 并在识别之后执行第一指令， 完成用户的语音控 制过程， 相较于已知的技术， 完善了电视机的语音控制功能。
本公开的实施例提供一种电视机 30， 如图 3所示， 所述电视机包括： 釆集单元 301， 所述釆集单元 301用于釆集用户的第一语音信号。 显示单元 302， 用于当所述电视机 30无法识别所述釆集单元 301釆集到 的所述第一语音信号时， 显示指令界面， 所述指令界面包括 N个指令， 以便 于所述用户选择与所述第一语音信号相对应的第一指令， 所述第一指令为所 述 N个指令中任意一个指令。
存储单元 303， 用于根据预先建立的指令 -语音组对应关系， 将所述釆集 单元 301 釆集到的所述第一语音信号保存在所述第一指令对应的第一语音组 中， 所述第一语音组中包括触发第一指令的所有语音信号。
这样一来， 当电视机无法识别釆集单元釆集到的第一语音信号， 即电视 机无法识别用户的语音指令时， 能够通过显示单元显示指令界面， 该指令界 面包括 N个指令， 用户可以根据需要选择需要电视机执行的第一指令， 然后 电视机执行第一指令， 并根据预先建立的指令 -语音组对应关系， 通过存储单 元将第一语音信号保存在第一指令对应的第一语音组中， 以便于用户再次通 过第一语音信号触发第一指令， 相较于已知的技术， 完善了电视机的语音控 制功能。
进一步地， 如图 4所示， 所述电视机 30还包括：
建立单元 304， 用于建立所述指令 -语音组对应关系， 所述指令-语音组对 应关系用于指示所述 N个指令与 N个语音组的对应关系，使得所述 N个指令 中的每个指令对应一个语音组。 示例的，假设 N为 4， 该 4个指令分别为 "播 放"、 "暂停"、 "快进" 和 "快退"， 若 "播放" 为第一指令， 对应的语音组为 第一语音组， 第一语音组中包括 M个语音信号， 则当用户进行语音控制时， 电视机釆集到的语音信号为该 M个语音信号中的任意一个语音信号， 均可触 发电视机执行播放的动作。
可选地， 在初始化时， 可以为电视机的 N个可执行指令录制标准语音信 号， 即所述 N个语音组中的每个所述语音组中包括标准语音信号， 所述标准 语音信号是由标准普通话录制生成的。
如图 5所示， 所述电视机 30还包括： 编号单元 305， 用于为所述 N个指 令进行编号， 使得每个所述指令对应一个数字， 以便于所述用户根据所述数 字， 选择对应的指令。
