Question

我正在使用Google Speech REST API将语音转换为文本得到空白的回应。这是我在Http中传递的json 邮寄申请： -

这是我获取JSON的代码：

File file = new File(mOutputFile.getAbsolutePath());
        byte[] bytes = new byte[0];
        try {
            bytes = loadFile(file);
        } catch (IOException e) {
            e.printStackTrace();
        }
        byte[] encoded = Base64.encodeBase64(bytes);
        String encodedString = new String(encoded);

        JSONObject config = new JSONObject();
        config.put("encoding", "FLAC");
        config.put("sampleRateHertz", 16000);
        config.put("languageCode", "en-US");
        config.put("enableWordTimeOffsets", false);
        JSONObject audio = new JSONObject();
        audio.put("content", "" + encodedString);
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("config", config);
        jsonObject.put("audio", audio);
        try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpPost post = new HttpPost("https://speech.googleapis.com/v1/speech:recognize?key=GOOGLE_API_KEY");
            post.setHeader("content-type", "application/json; charset=UTF-8");
            StringEntity entity = new StringEntity(jsonObject.toString());
            post.setEntity(entity);
            HttpResponse resp = httpClient.execute(post);
            s = EntityUtils.toString(resp.getEntity());
            Log.e("ExecuteTask Response", "--------------" + s);
        } catch (Exception e) {
            e.printStackTrace();
        }

    } catch (Exception exception) {
        exception.printStackTrace();
    }

您是否检查了official docs中的问题排查？在那里说

＆＃34;如果没有返回成绩单（例如，您收到一个空的{} JSON 响应）并且没有发生错误，音频很可能是没有使用正确的编码。＆＃34;

您应该在encode your file之前确保音频编码与JSON文件的参数匹配。在您的情况下"encoding": "FLAC"和"sampleRateHertz":16000
