NSSpeechRecognizer 示例

好的，所以我需要这样做：

等待命令“晚安”。然后运行一个动作。

有人可以解释如何实现这一点吗？

试试这个网站：

并修改如下：

NSSpeechRecognizer *listen;
NSArray *cmds = [NSArray arrayWithObjects:@"goodnight",nil];
listen = [[NSSpeechRecognizer alloc] init];
[listen setCommands:cmds];
[listen setDelegate:self];
[listen setListensInForegroundOnly:NO];
[listen startListening];
[listen setBlocksOtherRecognizers:YES];

- (void)speechRecognizer:(NSSpeechRecognizer *)sender didRecognizeCommand:(id)aCmd {
    if ([(NSString *)aCmd isEqualToString:@"goodnight"]) {
        [self performSelector:@selector(goodnightMethod:)];
    }
}

你处理晚安的方法是（根据我写的）：

-(void)goodnightMethod:(id)sender {
    //Do stuff here...
}
