python - Speaker recognition - Bad Request error on microsoft oxford

Question

I am using the python wrapper that has been given in the SDK section. I've been trying to enroll a voice file for a created profile using the python API.

I was able to create a profile and list all profiles successfully. But when I try to enroll a voice (.wav) file with a simple hello world phrase with the created profile, I get the error 'ERROR:root:Error enrolling profile.' which in the trace tells 'Exception: Error enrolling profile: Bad Request'. I've used by importing the module to my python file as well as in command line as described in the Readme.

I have no clue whether this API will work or not. I don't think there is any other API for my little experiment. There are no proper responses even in the issues section of the SDK.

PS: This is my first question. Pardon my styles and formats. The following is the stack trace:

ERROR:root:Error enrolling profile.

Exception: Error enrolling profile: Bad Request

Answer 1

The Speaker Identification code requires that enrollment audio "should be at least 20 seconds long and no longer than 5 minutes. The minimum number of total speech needed for enrollment, after removing silence, is 60 seconds" per documentation.
