我有这个测试lambda function代码，每当我使用Amazon Lex的音频功能时，我都会收到错误 - An error has occurred: Invalid SSML request (Service: AmazonParrot; Status Code: 400; Error Code: InvalidSsmlException
我的代码是：
def close(session_attributes, fulfillment_state, message):
response = {
'sessionAttributes': session_attributes,
'dialogAction': {
'type': 'Close',
'fulfillmentState': fulfillment_state,
'message': message
}
}
return response
def testing(intent_request, outputDialogMode):
slots = intent_request['currentIntent']['slots']
name = slots['name']
session_attributes = intent_request['sessionAttributes'] if
intent_request['sessionAttributes'] is not None else {}
if outputDialogMode == 'Text':
return close(
session_attributes,
'Fulfilled',
{
'contentType': 'PlainText',
'content': 'Hi {}'.format(name)
}
)
elif outputDialogMode == 'Voice':
return close(
session_attributes,
'Fulfilled',
{
'contentType': 'SSML',
'content': 'Hi {}'.format(name)
}
)
def dispatch(intent_request):
"""
Called when the user specifies an intent for this bot.
"""
logger.debug('input_request={}'.format(intent_request))
intent_name = intent_request['currentIntent']['name']
outputDialogMode = intent_request['outputDialogMode']
# Dispatch to your bot's intent handlers
if intent_name == 'testing':
return testing(intent_request, outputDialogMode)
raise Exception('Intent with name ' + intent_name + ' not supported')
# --- Main handler ---
def lambda_handler(event, context):
"""
Route the incoming request based on intent.
The JSON body of the request is provided in the event slot.
"""
# By default, treat the user request as coming from the America/New_York time zone.
os.environ['TZ'] = 'America/New_York'
time.tzset()
return dispatch(event)
根据this document，支持的contentType支持PlainText SSML和 <?xml version="1.0" encoding="utf-8"?>

。当我输入输入时，它可以正常工作，但是当我说话时，它会在最后输出错误。可能是什么原因？
