ios - 动态更改 OpenEars 音调(即时)

Question

我有一个使用 OpenEars API 读取文本的 iOS 应用程序。我使用的是最新版本 (1.2.5)。我无法弄清楚如何在阅读单词时改变音调(“即时”)。我创建了一个 slider 来控制音高。更改 slider 时会触发委托(delegate)。在委托(delegate)函数中，更改了 FliteController target_mean。目的是在 target_mean 值更改后立即更改音高。我的代码如下:

-(void)sayTheMessage:(NSString *)message {

    // if there is nothing there, don't try to say anything
    if (message == nil)
        return;

    [self.oeeo setDelegate:self];

    // we are going to say what is in the label...
    @try {

        // set the pitch, etc...
        self.flite.target_mean = pitchValue; // Change the pitch
        self.flite.target_stddev = varienceValue; // Change the variance
        self.flite.duration_stretch = speedValue; // Change the speed

        // finally say it!
        [self.flite say:message withVoice:self.slt];

    }
    @catch (NSException *exception) {

        if ([delegate respondsToSelector:@selector(messageError)])
            [delegate messageError];        
    }
    @finally {

    }
}


-(void)changePitch:(float)pitch {

    if ((pitch >= 0) && (pitch <= 2)) {

        // save the new pitch internally
        pitchValue = pitch;

        // change the pitch of the current speaking....
        self.flite.target_mean = pitchValue;
    }

}

有什么想法吗？

这里是 OpenEars 开发者。您无法使用 FliteController 即时更改音高，因为音高是在处理语音之前设置的。
