Bing文字轉語音在Android中不起作用

Question

因此，我克隆了示例Cognitive-Speech-TTS並測試了Android TTS，但無法正常工作，我聽不到任何結果/聲音，我已經完成了必要的要求，例如獲得API訂閱密鑰並對其進行管理。 所以這里的Logcat結果

Answer 1

我通過使用XmlDom類獲取SSML解決了該問題

字符串正文= XmlDom.createDom（deviceLanguage，genderName，voiceName，“此處輸入文字”）；

byte [] xmlBytes = body.getBytes（）;

urlConnection.setRequestProperty（“ content-length”，String.valueOf（xmlBytes.length））;

public class XmlDom {
    public static String createDom(String locale, String genderName, String voiceName, String textToSynthesize){
        Document doc = null;
        Element speak, voice;
        try {
            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = dbf.newDocumentBuilder();
            doc = builder.newDocument();
            if (doc != null){
                speak = doc.createElement("speak");
                speak.setAttribute("version", "1.0");
                speak.setAttribute("xml:lang", "en-us");
                voice = doc.createElement("voice");
                voice.setAttribute("xml:lang", locale);
                voice.setAttribute("xml:gender", genderName);
                voice.setAttribute("name", voiceName);                        voice.appendChild(doc.createTextNode(textToSynthesize));
                speak.appendChild(voice);
                doc.appendChild(speak);
            }
        } catch (ParserConfigurationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return transformDom(doc);
    }

    private static String transformDom(Document doc){
        StringWriter writer = new StringWriter();
        try {
            TransformerFactory tf = TransformerFactory.newInstance();
            Transformer transformer;
            transformer = tf.newTransformer();
            transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
            transformer.transform(new DOMSource(doc), new StreamResult(writer));
        } catch (TransformerException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return writer.getBuffer().toString().replaceAll("\n|\r", "");
    }
}

更新：

使用XmlDom類獲取SSML之后，我發現SSML需要在語音標簽中指定xml：lang ='YOU_LANGUAGE_HERE' 。 例如

<speak version='1.0' xml:lang='en-US'><voice xml:lang='en-US' xml:gender='Female' name='Microsoft Server Speech Text to Speech Voice (en-US, ZiraRUS)'>This is a demo of Microsoft Cognitive Services Text to Speech API.</voice></speak>
