Speaker Recognition API
Speaker Recognition - Identification
To automatically identify who is speaking given a group of speakers.
Select the testing console in the region where you created your resource:
Open API testing consoleRequest URL
Request parameters
Comma-delimited identificationProfileIds, the id should be Guid.
It can only support at most 10 profiles for one identification request.
Instruct the service to waive the recommended minimum audio limit needed for identification. Set value to “true” to force identification using any audio length (min. 1 second).
Request headers
Request body
You should include the enrollment audio file in the request body. The minimum recommended amount of accumulated speech for identification, after removing silence, is 30 seconds.
In the case you wish to start identification using any amount of speech time, you should include the "shortAudio" parameter. It instructs the service to waive the recommended 30 seconds of audio needed to do identification. When doing so you can send audio files starting 1-second-long but no longer than 5 minutes.
The audio file format must meet the following requirements.
Container | WAV |
---|---|
Encoding | PCM |
Rate | 16K |
Sample Format | 16 bit |
Channels | Mono |
[BinaryData]
[BinaryData]
Response 202
Accepted means that the service has accepted the request and will start processing later.
It will return Accepted immediately and add the operation location in header for you to retrieve result status with operation Speaker Recognition - Get Operation Status.
