java呼叫騰訊云介面-第二篇（錄音檔案識別）

• 需要先請求任務，再請求結果，隔一段時間才能去取到結果

2.語音轉文本(任務)

2.1 需要依賴

<!-- 統一版本管理中-->            
<tencentcloud.version>3.1.317</tencentcloud.version>
<!--騰訊語音識別-->
<dependency>
	<groupId>com.tencentcloudapi</groupId>
	<artifactId>tencentcloud-sdk-java</artifactId>
	<version>${tencentcloud.version}</version>
</dependency>
<!--然后在需要用到的地方引入這個-->
<dependency>
	<groupId>com.tencentcloudapi</groupId>
	<artifactId>tencentcloud-sdk-java</artifactId>
</dependency>

2.2 使用

//分段，第一段獲取taskId,第二段獲取文本
//獲取語音轉文本任務id
    private Long getVoiceTaskId(String url) {
//String url = "http://www.luyin.com/upload/duanjuyuyin1206010.mp3";
        try {
	        String secretId = TencentSecret.SECRET_ID;
	        String secretKey = TencentSecret.SECRET_KEY;
            Credential cred = new Credential(secretId, secretKey);
            HttpProfile httpProfile = new HttpProfile();
            httpProfile.setEndpoint("asr.tencentcloudapi.com");
            ClientProfile clientProfile = new ClientProfile();
            clientProfile.setHttpProfile(httpProfile);
            AsrClient client = new AsrClient(cred, "", clientProfile);
            CreateRecTaskRequest req = new CreateRecTaskRequest();
            req.setEngineModelType("16k_zh");//中文語音通用
            req.setChannelNum(1L);//單聲道
            req.setResTextFormat(0L);//識別結果文本(含分段時間戳)
            req.setSourceType(0L);//0：語音 URL
            req.setUrl(url);//音頻地址
            CreateRecTaskResponse resp = client.CreateRecTask(req);
            String voiceTaskResult = CreateRecTaskResponse.toJsonString(resp);
            VoiceReadResult voiceReadResult = JSON.parseObject(voiceTaskResult, VoiceReadResult.class);
            if (voiceReadResult != null) {
                Object taskData = voiceReadResult.getData();
                VoiceReadResult res = (VoiceReadResult) taskData;
                Long taskId = res.getData().getTaskId();
                return taskId;
            }
        } catch (TencentCloudSDKException e) {
            system.out.println("騰訊音頻轉化任務介面呼叫失敗，錯誤資訊:"+e);
            return null;
        }
        return null;
    }

    //獲取語音轉文本查詢結果
    private String getVoiceText(Long taskId) {
        try {
	        String secretId = TencentSecret.SECRET_ID;
	        String secretKey = TencentSecret.SECRET_KEY;
            Credential cred = new Credential(secretId, secretKey);
            HttpProfile httpProfile = new HttpProfile();
            httpProfile.setEndpoint("asr.tencentcloudapi.com");
            ClientProfile clientProfile = new ClientProfile();
            clientProfile.setHttpProfile(httpProfile);
            AsrClient client = new AsrClient(cred, "", clientProfile);
            DescribeTaskStatusRequest req = new DescribeTaskStatusRequest();
            req.setTaskId(taskId);
            DescribeTaskStatusResponse resp = client.DescribeTaskStatus(req);
            String voiceTextResult = CreateRecTaskResponse.toJsonString(resp);
            VoiceReadResult voiceReadResult = JSON.parseObject(voiceTextResult, VoiceReadResult.class);
            if (voiceReadResult != null) {
                Object textData = voiceReadResult.getData();
                VoiceReadResult res = (VoiceReadResult) textData;
                String text = res.getData().getResult();
                return text;
            }
        } catch (TencentCloudSDKException e) {
            system.out.println("騰訊音頻轉化任務介面呼叫失敗，錯誤資訊:"+ e);
            return null;
        }
        return null;
    }
