Watson TTS 不允许选择语音

Question

创建了一个 Bluemix 应用程序来获取正确的凭据并使用 Fiddler Text to Speech (TTS) 来记录提示。录音使用默认的“Michael”语音。我想要艾莉森。

如果我尝试传入“voice”，我会收到以下错误，即使我指定“Michael”作为我的选择：

{
  "code_description": "Bad request",
  "code": 400,
  "error": "The argument(s) [u'voice'} are not allowed."
}

这是我的有效载荷：

{
"text": "Hello,, this is Dora. How are you today?",
"voice": "en-US_AllisonVoice"
}

我有开发者帐号，是否需要注册才能使用“语音”？即使我传入默认的“迈克尔”？

Answer 1

我认为您的问题在于您指定 voice 参数的方式。
voice 和 text 参数可以作为 GET 中的查询参数发送。

示例

1.卷曲

curl -u "{username}":"{password}" "https://stream.watsonplatform.net/text-to-speech/api/v1/synthesize?voice=en-US_AllisonVoice&text=Hello%2C%20this%20is%20Dora.%20How%20are%20you%20today%3F"

节点

var watson = require('watson-developer-cloud');
var fs = require('fs');

var text_to_speech = watson.text_to_speech({
  username: '<username>',
  password: '<password>',
  version: 'v1'
});

var params = {
  text: 'Hello, this is Dora. How are you today?',
  voice: 'en-US_AllisonVoice',
  accept: 'audio/wav'
};

// Pipe the synthesized text to a file
text_to_speech.synthesize(params).pipe(fs.createWriteStream('output.wav'));
