对接阿里云实时语音转文字的思路

news 2025/8/3 3:53:59

将上述概念转化为详细代码需要一定的步骤。这里，我们将根据之前讨论的服务划分，创建一个简化的框架来模拟这个流程。注意，由于空间限制和简化目的，某些实现细节会被省略或简化，你可能需要根据实际情况进行调整。

1. 配置和认证服务（ConfigAndAuthService）

首先，创建一个负责获取Token和基础配置信息的服务。

import java.io.IOException;public class ConfigAndAuthService {private String id;private String secret;private String appKey;private String accessToken;private long expireTime;public ConfigAndAuthService(String id, String secret, String appKey) {this.id = id;this.secret = secret;this.appKey = appKey;}public void applyToken() throws IOException {// 模拟获取Token的逻辑this.accessToken = "Your_Access_Token";this.expireTime = System.currentTimeMillis() + 3600 * 1000; // 假设Token有效期1小时System.out.println("Token applied. Expire time: " + this.expireTime);}public String getAccessToken() {return accessToken;}public String getAppKey() {return appKey;}// 根据需要添加更多getter方法
}

2. 音频流处理服务（AudioStreamService）

这个服务负责读取音频流并发送给ASR服务。

import java.io.File;
import java.io.FileInputStream;public class AudioStreamService {private SpeechTranscriber transcriber;public AudioStreamService(SpeechTranscriber transcriber) {this.transcriber = transcriber;}public void sendAudioStream(String filepath) throws Exception {File file = new File(filepath);FileInputStream fis = new FileInputStream(file);byte[] buffer = new byte[3200];int read;while ((read = fis.read(buffer)) > -1) {transcriber.send(buffer, read);// 根据需要调整休眠时间Thread.sleep(50);}fis.close();}
}

3. ASR事件监听服务（ASREventListenerService）

实现SpeechTranscriberListener的具体逻辑。

public class ASREventListenerService extends SpeechTranscriberListener {@Overridepublic void onTranscriptionResultChange(SpeechTranscriberResponse response) {System.out.println("Interim result: " + response.getResult());}@Overridepublic void onSentenceEnd(SpeechTranscriberResponse response) {System.out.println("Final result: " + response.getResult());}@Overridepublic void onTranscriberStart(SpeechTranscriberResponse response) {System.out.println("Transcriber started");}@Overridepublic void onTranscriptionComplete(SpeechTranscriberResponse response) {System.out.println("Transcription completed");}@Overridepublic void onFail(SpeechTranscriberResponse response) {System.out.println("Transcription failed: " + response.getStatusText());}// 实现其他必要的方法...
}

4. 应用启动和管理服务（ApplicationManagementService）

负责启动和管理整个应用的服务。

public class ApplicationManagementService {public static void main(String[] args) throws Exception {String id = "Your_Aliyun_AccessKeyId";String secret = "Your_Aliyun_AccessKeySecret";String appKey = "Your_Aliyun_AppKey";ConfigAndAuthService authService = new ConfigAndAuthService(id, secret, appKey);authService.applyToken(); // 获取TokenNlsClient client = new NlsClient(authService.getAccessToken());SpeechTranscriber transcriber = new SpeechTranscriber(client, new ASREventListenerService());transcriber.setAppKey(authService.getAppKey());// 设置其他transcriber参数...AudioStreamService audioStreamService = new AudioStreamService(transcriber);audioStreamService.sendAudioStream("path_to_your_audio_file.wav");client.shutdown();}
}
