How to identify speaker from voice pattern using Microsoft Speech?

Question

I'm using Microsoft Speech C# API for Home Automation commands

I'd like to know if there is a way or built-in C# method to hash Voice Input and recognize who's speaking. If it is Alice or Bob to say "Hello Alice" or "Hello Bob".

EDIT:

Microsoft Speech API can provides a .wav of the recording. It might be able to hash, process, ... to understand who's speaking:

• Loud voice, slow modulation, ... => Bob
• High voice, fast modulation, ... => Alice

Answer 1

Speaker recognition is a hard problem and is still an active research area. I don't think Microsoft speech api has any speaker recognition support, but not 100% sure.

I found the following article really helpful while researching the topic. It introduces the subject and also provides a very crude implementation. Probably a good place to start.

Answer 2

You can use Microsoft Speaker Recognition APIs for doing this task: https://www.microsoft.com/cognitive-services/en-us/speaker-recognition-api

Microsoft is providing two APIs for this purpose: Speaker Verification & Speaker Identification.

You can find their C# & Python SDKs here: https://github.com/Microsoft/ProjectOxford-ClientSDK/tree/master/SpeakerRecognition
