How can I authorize on the site using voice recognition?

Question

User identification

Tell me, is it possible to make authorization on the site using voice?
We go to the site, press the button, say our previously recorded voice, the system recognizes and authorizes. Thanks

Answer 1

1. Standard - we hash the stream captured from the microphone into the database.
2. Comparison - we make a fuzzy comparison of the hashes of the received one with the reference one. (weight tree, Hamming distance, neural network, etc.)
3. According to the result - authorize or not.
Increase security simply: login history (cookies, IP, etc.) + voice!
New PC (or subnet) - two-factor authentication then...
Main problems: sound distortion in different microphones and in the environment (noise, echo, etc.).

Answer 2

There is a Web Audio Api, so it's theoretically possible. Another question is that it is wildly difficult and not 100% safe. In the context of two-factor authorization, it can be normal.
In any case, look for an API for something like this. Purely theoretically, Google provides a similar API ...

Answer 3

And if the voice parameters are programmatically faked? Benefit from such authorization?
