Question

我注意到Google演讲最近的表现有所不同

例如，在此文件中，扬声器在正确转录为“ 123457”之前用泰语说“ 123457”，但是由于某些原因，现在API返回“ 12345”

flac文件：http://s000.tinyupload.com/index.php?file_id=76277841017264777654

Python代码：

from oauth2client.client import GoogleCredentials
DISCOVERY_URL = ('https://{api}.googleapis.com/$discovery/rest?'

    credentials = GoogleCredentials.get_application_default().create_scoped(
        ['https://www.googleapis.com/auth/cloud-platform'])
    http = httplib2.Http()
    credentials.authorize(http)
    return discovery.build(
        'speech', 'v1beta1', http=http, discoveryServiceUrl=DISCOVERY_URL)

Google Speech转录被砍掉了吗？
