AVSpeechSynthesizer错误AudioSession

Question

我正在玩AVSpeechSynthesizer并且总是遇到这些错误:

ERROR:     >aqsrv> 65: Exception caught in (null) - error -66634
ERROR:     AVAudioSessionUtilities.h:88: GetProperty_DefaultToZero: AudioSessionGetProperty ('disa') failed with error: '?ytp'

我的代码是:

AVSpeechSynthesizer *synthesizer = [[AVSpeechSynthesizer alloc] init];
[synthesizer setDelegate:self];
speechSpeed = AVSpeechUtteranceMinimumSpeechRate;
AVSpeechUtterance *synUtt = [[AVSpeechUtterance alloc] initWithString:[[self text] text]];
[synUtt setRate:speechSpeed];
[synUtt setVoice:[AVSpeechSynthesisVoice voiceWithLanguage:languageCode]];
[synthesizer speakUtterance:synUtt];

有谁知道如何解决这些错误？

Answer 1

我得到了上面的代码,以最小的调整在模拟器上工作.

1. 在[[self text] text]你的代码位可能是错的(这是该Exception caught in (null)错误将来自).下面的代码对我有用.

   AVSpeechSynthesizer *synthesizer = [[AVSpeechSynthesizer alloc] init];
   [synthesizer setDelegate:self]; // set your class to conform to the AVSpeechSynthesizerDelegate protocol
   float speechSpeed = AVSpeechUtteranceMinimumSpeechRate;
   AVSpeechUtterance *synUtt = [[AVSpeechUtterance alloc] initWithString:@"hello I am testing"];
   [synUtt setRate:speechSpeed];
   [synUtt setVoice:[AVSpeechSynthesisVoice voiceWithLanguage:[AVSpeechSynthesisVoice currentLanguageCode]]];
   [synthesizer speakUtterance:synUtt];
   

   当我说"工作"时,我的意思是我在模拟器中听到了说出我的测试句的声音.

   我还是看到了这个警告:

   2013-09-21 11:37:56.454演讲[5550:3a03] 11:37:56.454错误:AVAudioSessionUtilities.h:88:GetProperty_DefaultToZero:AudioSessionGetProperty('disa')失败,错误:'？ytp'

2. Xcode 5似乎有一个缓慢的时间尝试#import <AVFoundation/AVFoundation.h>使用这个SpeechSynthesis代码的传统,在使用新的时候,事情似乎加速了很多@import AVFoundation;.
