A factory function to construct an object of typeSpeechConnection.
The returned connection object should not be used directly; instead it should be passed as an argument to the constructor ofSpeechClient.
The optionaloptionsargument may be used to configure aspects of the returnedSpeechConnection. Expected options are any of the types in the following option lists:
