此博客实现与java实现微软文本转语音（TTS）经验总结_java tts_${简简单单}的博客-CSDN博客之上，首先感谢博客源码的提供，本人在上面添加了一些详细的注释，方便大家跟好的理解和使用，毕竟我已经用原文调试了一下午才调通，一些细节的问题给大家标注出来，免得浪费大家的时间，下面直接开始代码吧！
首先大家需要去微软官网获取到密钥，方便调用时可以使用，大家注意看下图，我们一定要注意给我们分配到的区域，我这里是分配到eastus ,就是east us（美国东部）的意思，大家一定需要注意一下，后面会使用到的，然后终结点里面的地址就是我们获取token的地址
下面我们准备几个类，方便后面使用，大家把代码都复制到自己项目中，不要有遗漏：
package com.daoversal.util; public class ByteArray { private byte[] data; private int length; public ByteArray(){ length = 0; data = new byte[length]; } public ByteArray(byte[] ba){ data = ba; length = ba.length; } /** 合并数组 */ public void cat(byte[] second, int offset, int length){ if(this.length + length > data.length) { int allocatedLength = Math.max(data.length, length); byte[] allocated = new byte[allocatedLength << 1]; System.arraycopy(data, 0, allocated, 0, this.length); System.arraycopy(second, offset, allocated, this.length, length); data = allocated; }else { System.arraycopy(second, offset, data, this.length, length); } this.length += length; } public void cat(byte[] second){ cat(second, 0, second.length); } public byte[] getArray(){ if(length == data.length){ return data; } byte[] ba = new byte[length]; System.arraycopy(data, 0, ba, 0, this.length); data = ba; return ba; } public int getLength(){ return length; } }package com.daoversal.util; import javax.net.ssl.HttpsURLConnection; import java.net.URL; public class HttpsConnection { public static HttpsURLConnection getHttpsConnection(String connectingUrl) throws Exception { URL url = new URL(connectingUrl); return (HttpsURLConnection) url.openConnection(); } }package com.daoversal.util; import lombok.extern.slf4j.Slf4j; import org.w3c.dom.Document; import org.w3c.dom.Element; import javax.xml.parsers.DocumentBuilder; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.parsers.ParserConfigurationException; import javax.xml.transform.OutputKeys; import javax.xml.transform.Transformer; import javax.xml.transform.TransformerException; import javax.xml.transform.TransformerFactory; import javax.xml.transform.dom.DOMSource; import javax.xml.transform.stream.StreamResult; import java.io.StringWriter; @Slf4j 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) { log.error("Create ssml document failed: {}",e.getMessage()); return null; } 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) { log.error("Transform ssml document failed: {}",e.getMessage()); return null; } return writer.getBuffer().toString().replaceAll("\n|\r", ""); } }下面这个类我给大家重点讲一下，大家去下面网址看看自己的参数Text to speech API reference (REST) - Speech service - Azure AI services | Microsoft Learn
AUDIO_24KHZ_48KBITRATE_MONO_MP3 ：语言类型，这个不重要，那个声音好听用那个，去下图找：
ACCESS_TOKEN_URI ：就是本文章的第一张图里面，里面获取token的地址，直接将地址复制进来就好了。
API_KEY ：自己的api key,就是密钥。
TTS_SERVICE_URI ： 这个地址一定要对应分配的区域才行，不然会报权限错误
Synthesis tts speech failed Server returned HTTP response code: 401 for URL: https://.........
我这里是 east us（美国东部），所以就使用美国东部里面的地址即可。
package com.daoversal.util; public class TtsConst { /** * 音频合成类型（亲测这种效果最佳，其他的你自己去试试） * 里面有很多类型,可以去里面找自己需要的 * https://learn.microsoft.com/en-us/azure/ai-services/speech-service/rest-text-to-speech?tabs=streaming */ public static final String AUDIO_24KHZ_48KBITRATE_MONO_MP3 = "audio-24khz-48kbitrate-mono-mp3"; /** * 授权url 获取密钥页面 终结点 里面的地址，我们使用这个获取token */ public static final String ACCESS_TOKEN_URI = "token获取地址"; /** * api key */ public static final String API_KEY = "自己的密钥"; /** * tts服务url，这里一定要根据自己分配的地区找相应的地址才行 */ public static final String TTS_SERVICE_URI = "https://eastus.tts.speech.microsoft.com/cognitiveservices/v1/"; }下面参数给大家讲一下：
textToSynthesize ： 传入的合成语音文本内容
locale：语言类型，大家可以参考，中文在嵌入式语音里面，大家可以在两个页面找到自己需要的语言。
Embedded Speech - Speech service - Azure AI services | Microsoft Learn
Language support - Speech service - Azure AI services | Microsoft Learn
gender：为发声人性别，Male表示男性
voiceName ：发声者名称，大家可以去下图找出对应的，比如中文的话：
