IBM Watson语音到文本Python，“ DetailedResponse”对象没有属性“ getResult”

我正在使用Python在Flask中设计一个利用IBM Watson的语音转文本功能的项目。我现在要做的只是加载一个FLAC文件（0001.flac），通过Watson解释该文件，然后将结果打印到我的控制台上。到目前为止，我已经编写了以下代码（我替换了示例的用户名和密码）：

from werkzeug import secure_filename
import pprint, json, os
from watson_developer_cloud import SpeechToTextV1

. . .

speech_to_text = SpeechToTextV1(
username='My username is here',
password='My password is here')

with open(os.path.join(os.path.dirname(__file__), '0001.flac'), 'rb') as audio_file:
    speech_to_text.set_detailed_response(True)
    outthis = speech_to_text.recognize(
          audio_file, content_type='audio/flac', timestamps=True)
    pprint.pprint(json.dumps(outthis.getResult(), indent=2))

这是我的输出：

AttributeError: 'DetailedResponse' object has no attribute 'getResult'

根据Watson文档（https://www.ibm.com/watson/developercloud/speech-to-text/api/v1/python.html?python#introduction），我应该能够通过DetailsResponse上的getResult接收信息目的。我究竟做错了什么？
