"Google Speech to Text" does not give accurate results when used for login or registration

Question

In my android app i want user to be logged in through voice but google speech to text always gives wrong result.

Answer 1

Speech recognition is still very new tech, and it isn't advanced enough to understand the difference in terms of when to convert the word dot into . vs the String literal dot.

In addition, depending on the surroundings (background noise), pronunciation, accent and a lot of other language-related variables, there's a chance it'll misinterpret what you say. The dot->(.|dot) is just one example of that.
The same applies with emails, because when you say dot, there's a high chance it'll interpret that directly, instead of thinking of it as a character. There's the same with @ and other non-letter characters.

Besides, as Twometer said, using speech-to-text for login is not a good idea, considering security problems.
