微软（TTS）文本转语音服务API实现-个人在线分享

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;
    }
}

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：

微软（TTS）文本转语音服务API实现插图

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: http://………

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
     * http://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 = "http://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。

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：

最后就是调用了，大家可以测试了：

        byte[] bte = testService.genAudioBytes(text,"zh-CN","Male","zh-CN-YunxiNeural");
        String value = "hllo.mp3";
        convertByteArrayToFile(bte,value);
        System.out.println("213213123");
    }

    /**
     * 此文件是将byte[] 转换成文件存储到指定路径的

    public static void convertByteArrayToFile(byte[] arr,String value) {
        try (
                BufferedInputStream bis = new BufferedInputStream(new ByteArrayInputStream(arr));
                //这里是转换以后的文件存储的路径
                FileOutputStream fileOutputStream = new FileOutputStream("/Users/recovery/Downloads/"+value);
                BufferedOutputStream bos = new BufferedOutputStream(fileOutputStream)
        ) {
            int data;
            while ((data = bis.read()) != -1) {
                bos.write(data);
            }
            bos.flush();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

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。
