微软（TTS）文本转语音服务API实现
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;

}
} 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：

return ba.getArray();
} catch (Exception e) {
log.error("Synthesis tts speech failed {}", e.getMessage());

return null;

}最后就是调用了，大家可以测试了：

最后大家需要注意一下就是如果你选的是英文en-US，但是输入的文本是中文的话他是不会翻译的，所以大家一定要注意自己的语言类型不要弄错了，如果有疑问可以留言哦，我看到肯定会毫无保留的给大家说明的。
