我有一个数据框。我想从数据帧的特定列中提取数据，并将这些单独的数据块保存在不同的变量中。

我想根据说话者的值映射内容中的所有值，并将其存储在同名变量中。
例如输出：
spk_0 - From weekend All Star Game is over . It's time to get back down to business . You can't get thatchampionship . It's fun . Weekend
spk_1 - memorable . It couldn't be scripted any better . May be my last one . If this it'll be a hell of a DVD .
