如何在Azure text-to-speech中更改声音？

Question

我试着把我的React网站改成使用英国声音：

const voice = "Microsoft Server Speech Text to Speech Voice (en-GB, LibbyNeural)"
speechConfig.speechSynthesisVoiceName = voice;
speechConfig.speechRecognitionLanguage = "en-GB";
const audioConfig = AudioConfig.fromDefaultMicrophoneInput();

return new SpeechRecognizer(speechConfig, audioConfig);

但我听到的都是美国人的声音。我遗漏了什么？

Answer 1

正如Ryan所指出的，您将希望使用SpeechSynthesizer而不是SpeechRecognizer。这里有一个到TTS sample code on github的链接。

样例应该会让事情变得清晰起来，并让你开始行动起来。请务必注意audioConfig和speechConfig属性。例如，speechSynthesisVoiceName需要使用提供的here中的语音名称标签进行更改。(再往下一页是standard voices)。而speechRecognitionLanguage将被speechSynthesisLanguage取代。这些只是几个例子，但是github示例应该可以清楚地说明所有问题。

var audioConfig = sdk.AudioConfig.fromAudioFileOutput(filename);
var speechConfig = sdk.SpeechConfig.fromSubscription(settings.subscriptionKey, settings.serviceRegion);

// setting the synthesis language, voice name, and output audio format.
// see https://aka.ms/speech/tts-languages for available languages and voices
speechConfig.speechSynthesisLanguage = settings.language;
speechConfig.speechSynthesisVoiceName = "en-US-GuyNeural";

// create the speech synthesizer.
var synthesizer = new sdk.SpeechSynthesizer(speechConfig, audioConfig);

Answer 2

SpeechRecognizer用于将语音转换为文本，如果您想将文本转换为语音，则需要使用SpeechSynthesizer。
