I'm trying to find out of there is any Speech(or Voice) API(for Android) which can be used for recognition of the speaker. My aim is creating application which is going to recognize the speaker and differentiate it from another person, which can serve like authentication.
Thanks in advance,
I don't think you'll have much luck with the Recognizer intent, which is used to convert speech to text. I'm not aware of anything that does speaker recognition. But you could use AudioRecord to grab raw audio frames and then do signal processing on them. I'm afraid I'm not familiar with exactly which audio processors would help you differentiate one speaker from another though.
