TMBOY 44:c1d8923072ba 1 # directives的交互设计参考
TMBOY 44:c1d8923072ba 2
TMBOY 44:c1d8923072ba 3 ## directives的执行顺序
TMBOY 44:c1d8923072ba 4 一条返回值的结构体，包含一个directives数组
TMBOY 44:c1d8923072ba 5
TMBOY 44:c1d8923072ba 6 * 顺序执行directives数组中的指令
TMBOY 44:c1d8923072ba 7 * SpeechSynthesizer.Speak 指令，需要播报完了再取下一条
TMBOY 44:c1d8923072ba 8 * udioPlayer的指令，操作后台的播放器进程，执行时间会很短，执行完后立即取下一条。
TMBOY 44:c1d8923072ba 9 * Speaker等其它指令，block直接执行。
TMBOY 44:c1d8923072ba 10
TMBOY 44:c1d8923072ba 11 如果收到一条新的返回值结构体，停止之前的directives数组的执行（如果正在播报SpeechSynthesizer.Speak，停止播报），丢弃尚未执行的directives，执行新返回的directives数组。但是AudioPlayer的播放列表保持不变

TMBOY 44:c1d8923072ba 15 ## 声音内容输入输出的分类：
TMBOY 44:c1d8923072ba 16
TMBOY 44:c1d8923072ba 17 Channel：
TMBOY 44:c1d8923072ba 18
TMBOY 44:c1d8923072ba 19 * Alerts：闹钟Alerts
TMBOY 44:c1d8923072ba 20 * Dialog：用户对话，包括SpeechRecognizer, 不带channel="Content"的SpeechSynthesizer
TMBOY 44:c1d8923072ba 21 * Content：播放的内容，包括AudioPlayer指令的内容，带有channel="Content"的SpeechSynthesizer指令的内容 （会被用来读新闻，读故事等）
TMBOY 44:c1d8923072ba 22
TMBOY 44:c1d8923072ba 23 原则上，声音输入输出的优先级应该是Alerts > Dialog > Content
