对接阿里asr和Azure asr

1：对接阿里asr

1.1：pom

<dependency><groupId>com.alibaba.nls</groupId><artifactId>nls-sdk-recognizer</artifactId><version>2.2.1</version>
</dependency>

1.2：生成token

package com.dahuyou.ali.asr.generatetoken;import com.alibaba.nls.client.AccessToken;import java.io.IOException;/*** 生成token* program argument参数配置："LTAI5tNg9N*****R28Zazv" "bAgAvjZwc5HVr******ADEAa"** Token: 6599217b19214759*****42ddf0f8016, expire time: 1726774011*/
public class GenerateToken {public static void main(String[] args) {if (args.length < 2) {System.err.println("CreateTokenDemo need params: <accessKeyId> <accessKeySecret>");System.exit(-1);}String accessKeyId = args[0];String accessKeySecret = args[1];System.out.println("accessKeyId="+accessKeyId+"; accessKeySecret="+accessKeySecret);AccessToken accessToken = new AccessToken(accessKeyId, accessKeySecret);try {accessToken.apply();System.out.println("Token: " + accessToken.getToken() + ", expire time: " + accessToken.getExpireTime());} catch (IOException e) {e.printStackTrace();}}
}

其中accessKeyId和accessKeySecret通过阿里云后台获取：
