avspeechsynthesizer

问题 Everytime I use AVSpeechSynthesizer to speak text Instruments reports a memory leak in the AXSpeechImplementation library. Here's the code I'm using to make the call: AVSpeechUtterance *speak = [AVSpeechUtterance speechUtteranceWithString:text]; speak.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"en-US"]; speak.rate = AVSpeechUtteranceMaximumSpeechRate * .2; [m_speechSynth speakUtterance:speak]; Here's the link to the Instruments screenshot http://imageshack.com/a/img690/7993/b9w5.png

问题 What I want to do is allow my app to speak an utterance using AVSpeechSynthesizer while background audio apps are playing audio. While my app is speaking, I'd like the background apps' audio to "dim" and then return to their original volume after my app has finished speaking. In my AudioFeedback class, I initialize I setup the AVAudioSessions like so: self.session = [AVAudioSession sharedInstance]; NSError *error; [self.session setCategory:AVAudioSessionCategoryPlayback withOptions

问题 I am trying Speech recognition sample. If I started to recognise my speech via microphone, then I tried to get iPhone's voice of that recognised text. It is working. But, voice is too low. Can u guide me on this? Rather than, if I am trying in simple button action, with AVSpeechUtterance code, volume is normal. After that, If I go for startRecognise() method, volume is too low. My Code func startRecognise() { let audioSession = AVAudioSession.sharedInstance() //2 do { try audioSession

问题 HI did anyone tried AvSpeechSynthesizer on iOS 8 ? I did quick app on Xcode 6 but no audio comes out, I ran the same on on the Xcode 5 and works without a hitch. sample code from http://nshipster.com/avspeechsynthesizer/ NSString *string = @"Hello, World!"; AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc] initWithString:string]; utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"en-US"]; AVSpeechSynthesizer *speechSynthesizer = [[AVSpeechSynthesizer alloc] init];

问题 My map has 4 or 5 points close to each other and right now using AVSpeechSynthesizer I've got it so that it will say the name of the location (which is also displayed in a little bubble). I want it to still show that bubble but when clicked I want it to say a description of that place that I would have specified. This is my code at the moment: MapViewAnnotation.h @interface MapViewAnnotation : NSObject <MKAnnotation> { NSString *title; CLLocationCoordinate2D coordinate; NSString *desc; }

问题 I'm working to incorporate Apple speech synthesis audio unit stuff (works only on macOS, not iOS) into AudioKit and I've built a AKSpeechSynthesizer Class (initially created by wangchou in this pull request) and a demo project both available on the develop branch of AudioKit. My project is very similar to this Cocoa Speech Synthesis Example but on this project, the rate variable can be changed and varied smoothly between a low number of words per minute (40) up to a high number (300 ish).

问题 I need to disable the interaction with the user until the app finishes speaking. see example code below: self.view.userInteractionEnabled = NO; [self speak :@"wait for me to speak"]; self.view.userInteractionEnabled = YES; -(void)speak:(NSString*)word { AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc] initWithString:word]; utterance.rate = AVSpeechUtteranceMinimumSpeechRate; utterance.rate = 0.2f; utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage [AVSpeechSynthesisVoice

问题 I have no idea why I have this error. The error I got is Terminating app due to uncaught exception 'com.apple.coreaudio.avfaudio', reason: 'required condition is false: _recordingTap == nil' UPDATE Actually, this works, but after several times, suddenly the button is disabled and the mic no longer is in action. Then it causes the error and get crashed. Could you please help me with this? class ViewController: UIViewController, SFSpeechRecognizerDelegate, UITextViewDelegate,

问题 I've noticed an issue where IOS does not seem to localize the reading (by AVSpeechSynthesizer) of emojis on IOS 10.0 or higher, but it does seem to do it properly on IOS 9.3 or lower. If you tell an AVSpeechSynthesizer that's set to English to speak an emoji by sending it the string, "😀", it will say "Grinning face with normal eyes." When you change the voice language of the synth to anything other than English, such as French, for example, and send the same emoji, it should say "Visage

问题 I'm using AVSpeechSynthesizer for text to speech on 2 languages. Is there any way to specify speech stress on different part of the word? I've tried placing ' before and after desired vowel, and also using vowels with stress marks, e.g. ó , ý - which does not seem to have any impact. 回答1: In my case (language code is ru-RU), ` char helps to set word stress. 来源： https://stackoverflow.com/questions/32736130/avspeechsynthesizer-word-stress
