iphone - 文本转语音不起作用

Question

我正在使用 sfoster iPhone TTS。我想将文本转换为语音，还想将字符串拆分为字母，文本和每个字母都会发音。但它不发音文本和字母。我的代码如下:

-(void)spellOut:(NSString *)text{

[fliteEngine speakText:text];   
[fliteEngine setPitch:100.0 variance:50.0 speed:2.5];
[fliteEngine setVoice:@"cmu_us_rms"];

/* split a string into an array */

NSMutableArray *characters = [[NSMutableArray alloc] initWithCapacity:[text length]];

for (int i=0; i < [text length]; i++) {
    NSString *ichar  = [NSString stringWithFormat:@"%c", [text characterAtIndex:i]];
    [characters addObject:ichar];
}

/* set letter from each index of the array */

for (int i=0; i<[characters count]; i++) {

    NSString *letter = [characters objectAtIndex:i];

    NSLog(@"%@\n",letter);

    [fliteEngine speakText:letter];
    [fliteEngine setPitch:100.0 variance:50.0 speed:2.5];
    [fliteEngine setVoice:@"cmu_us_rms"];   
  }

}

问题出在哪里？

提前致谢。

首先，您似乎尚未启动 FliteTTS，因此请先执行此操作

fliteEngine = [[FliteTTS alloc] init];

然后，当我通过您的代码了解到，如果您使用此代码，它就会起作用 无需单独发音所有字符。

-(void)spellOut:(NSString *)text{

[fliteEngine speakText:text];
[fliteEngine setPitch:100.0 variance:50.0 speed:2.5];
[fliteEngine setVoice:@"cmu_us_rms"];

/* split a string into an array */

NSMutableArray *characters = [[NSMutableArray alloc] initWithCapacity:[text length]];

for (int i=0; i < [text length]; i++) 
 {
    NSString *ichar  = [NSString stringWithFormat:@"%c", [text characterAtIndex:i]];
    [characters addObject:ichar];
}


}

希望对您有帮助。
