Not in JSP, that's for certain. The JSP runs on the server and generates HTML. You're going to need some kind of client-side technology for that.

You could try with VoiceXML, but Im not sure how to implement it.

I'd say that the usual approach of voice recognition software is not going to help you here. The general goal of voice recognition is to recognize words spoken by of as many disparate users as possible. You, on the other hand, need an approach that would recognize differences in how these people pronounce the same passphrase and accept only the passphrase spoken by the authorized user. In general, you aren't even interested in recognizing the individual words in the passphrase (you in principle need to match the recorded sound to the sounds stored in your database and only accept recordings that are close enough to the one provided by the user). In some sense, this is exactly the opposite of what modern voice recognition software does.

In addition, you cannot rely on the passphrase not being known, as the user doing the authentication has to say it aloud to the microphone. Furthermore, nowadays there are lots of non-suspicious devices capable of recording and reproducing sounds (every mobile phone, for example), which might conceivably be used very easily to attack your system. Creating a safe system - and environment! - that would allow authentication based on voice is therefore going to be pretty hard.

I agree, does your authentication has to be speech recognition? Can't you use tokens as the second level of security?

A thing they know, A thing they have.
