由于我在这里使用过 HTML 解析和 text2speech，因此您可以执行 2 个步骤
1.get Attribute string from HTML file with below code works in iOS7+
根据您的客户观点：如果 HTML2Speech 市场上有任何 API 可能是其付费或
如果您使用任何 API，您将依赖该 API。而原生框架
将有助于满足您/客户的需求。
第 1 步：
[[NSAttributedString alloc] initWithData:[htmlString dataUsingEncoding:NSUTF8StringEncoding]
options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,
NSCharacterEncodingDocumentAttribute: @(NSUTF8StringEncoding)}
documentAttributes:nil error:nil];
然后你可以在AVSpeechUtterance中传递这个Attributed String
第 2 步：
使用以下方法获取 HTML2String：
/**
* "ConvertHTMLtoStrAndPlay" : This method will convert the HTML to String
synthesizer.
*
* @param aURLHtmlFilePath : "object of html file path"
*/
-(void)ConvertHTMLtoStrAndPlay:(UIButton*)aBtnPlayPause
isSpeechPaused:(BOOL)speechPaused
stringWithHTMLAttributes:(NSAttributedString*)aStrWithHTMLAttributes
{
if (synthesizer.speaking == NO && speechPaused == NO) {
AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc] initWithString:aStrWithHTMLAttributes.string];
//utterance.rate = AVSpeechUtteranceMinimumSpeechRate;
if (IS_ARABIC) {
utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"ar-au"];
}else{
utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"en-au"];
}
[synthesizer speakUtterance:utterance];
}
else{
[synthesizer pauseSpeakingAtBoundary:AVSpeechBoundaryImmediate];
}
if (speechPaused == NO) {
[synthesizer continueSpeaking];
} else {
[synthesizer pauseSpeakingAtBoundary:AVSpeechBoundaryImmediate];
}
}
和往常一样，当您需要停止使用下面的代码来停止语音时。
/**
* "StopPlayWithAVSpeechSynthesizer" : this method will stop the playing of audio on the application.
*/
-(void)StopPlayWithAVSpeechSynthesizer{
// Do any additional setup after loading the view, typically from a nib.
[synthesizer stopSpeakingAtBoundary:AVSpeechBoundaryImmediate];
}
希望这将帮助您获得 HTML2Speech 功能。
