OBJC AVSpeechUtterance writeUtterance 怎么样?
OBJC AVSpeechUtterance writeUtterance how?
我正在尝试创建一个 TTS 以在 Objc 中归档。
由于 iOS13 可以将其写入文件。
但我坚持 writeUtterance:toBufferCallback.
有人在 objc 中有这个函数的例子吗?
[synth speakUtterance:utterance];
Referring to the potential answer in Swift,这将是 Objective-C 实现
AVSpeechSynthesizer *synthesizer = [[AVSpeechSynthesizer alloc] init];
AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc] initWithString:@"test 123"];
AVSpeechSynthesisVoice *voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"en-US"];
[utterance setVoice:voice];
__block AVAudioFile *output = nil;
[synthesizer writeUtterance:utterance
toBufferCallback:^(AVAudioBuffer * _Nonnull buffer) {
AVAudioPCMBuffer *pcmBuffer = (AVAudioPCMBuffer*)buffer;
if (!pcmBuffer) {
NSLog(@"Error");
return;
}
if (pcmBuffer.frameLength != 0) {
//append buffer to file
if (output == nil) {
output = [[AVAudioFile alloc] initForWriting:[NSURL fileURLWithPath:@"test.caf"]
settings:pcmBuffer.format.settings
commonFormat:AVAudioPCMFormatInt16
interleaved:NO error:nil];
}
[output writeFromBuffer:pcmBuffer error:nil];
}
}];
