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;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.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：

package com.daoversal.util;import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import org.springframework.stereotype.Component;import javax.annotation.Resource;
import javax.net.ssl.HttpsURLConnection;
import java.io.DataOutputStream;
import java.io.InputStream;@Slf4j
@Component
public class TtsService {@Resourceprivate Authentication authentication;/*** 合成音频* @param textToSynthesize 传入需要翻译的文本* @param locale    要合成的语言类型* @param gender    性别* @param voiceName 发音者名称* @return*/public byte[] genAudioBytes(String textToSynthesize, String locale, String gender, String voiceName) {String accessToken = authentication.genAccessToken();if (StringUtils.isEmpty(accessToken)) {return new byte[0];}try {HttpsURLConnection webRequest = HttpsConnection.getHttpsConnection(TtsConst.TTS_SERVICE_URI);webRequest.setRequestProperty("Host", "eastus.tts.speech.microsoft.com");webRequest.setRequestProperty("Content-Type", "application/ssml+xml");webRequest.setRequestProperty("X-Microsoft-OutputFormat", TtsConst.AUDIO_24KHZ_48KBITRATE_MONO_MP3);webRequest.setRequestProperty("Authorization", "Bearer " + accessToken);webRequest.setRequestProperty("Ocp-Apim-Subscription-Key", TtsConst.API_KEY);webRequest.setRequestProperty("User-Agent", "Mozilla/5.0");webRequest.setRequestProperty("Accept", "*/*");webRequest.setDoInput(true);webRequest.setDoOutput(true);webRequest.setConnectTimeout(5000);webRequest.setReadTimeout(300000);webRequest.setRequestMethod("POST");String body = XmlDom.createDom(locale, gender, voiceName, textToSynthesize);if (StringUtils.isEmpty(body)) {return new byte[0];}byte[] bytes = body.getBytes();webRequest.setRequestProperty("content-length", String.valueOf(bytes.length));webRequest.connect();DataOutputStream dop = new DataOutputStream(webRequest.getOutputStream());dop.write(bytes);dop.flush();dop.close();InputStream inSt = webRequest.getInputStream();ByteArray ba = new ByteArray();int rn2 = 0;int bufferLength = 4096;byte[] buf2 = new byte[bufferLength];while ((rn2 = inSt.read(buf2, 0, bufferLength)) > 0) {ba.cat(buf2, 0, rn2);}inSt.close();webRequest.disconnect();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。
