Microsoft's Acoustic Caller ID Patent 185

Posted by samzenpus
from the who-do-you-sound-like-today dept.
theodp writes "A new patent granted to Microsoft Tuesday for automatic identification of telephone callers based on voice characteristics covers constructing acoustic models for telephone callers by identifying words or subject matter commonly used by callers and capturing the acoustic properties of any utterance. Not only that, it's done 'without alerting the caller during the call that the caller is being identified,' boasts Microsoft in the patent claims."

    The only difference here (aside from what agencies have been doing since the 1960's) is that this analysis seems to be done in real time, rather than offline? I mean, haven't monitoring people been able to tell who is speaking based on sound synthesis since forever?

I goofed around with computer telephony a bit back in the early 90's and I remember that already then the tech was pretty standard to pull the number and do the database lookup automatically. Saving the call center a few seconds per call adds up. The reasons they ask for it are a) people found it disconserting to have the call center rep greet them by name before they said anything and b) you might not be calling

    I read the patent, but I guess I don't get it. How is what Microsoft claiming to do different from existing voice recognition systems?

    You have to train current voice systems so they recognize your voice pattern (or, acoustic ID) and translate it to text or action. Take that and add a system that keeps profiles for a more advanced version of caller ID. It seems like a natural evolution of the technology.

    • "How is what Microsoft claiming to do different from existing voice recognition systems?"

      Existing voice recognition systems might be more acurately called speech recognition. They don't recognize the voice (who is speaking); they recognize the speech (what is being said). They can be categorized as speaker dependent or speaker independent.

      Speaker dependent speech recognition (type 1) requires complex training by each user. It needs to know all the ways a person pronounces every possible phoneme. During

        There are existing voice recognition systems as well. Some are used to choose which speech recognition profile to use, while some are used for other applications, similar to the one in the patent.
      • You're talking out of your ass.

        This is not speech recognition it's speaker recognition, and is nothing new.
    • That makes no sense. Just because you can train a system to work better at converting speach to text if it knows your voice pattern, doesn't mean that it can uniquely identify someone from the voice pattern. Those are two different things.....you can't just tell it to run the algorithm in reverse and expect there to be enough information. In fact, you aren't even running it in reverse if you don't have the text version of what they said.

The only "recording" going on is a few kbytes of data temporarily buffered for analysis: if it is immediately discarded and never available to be listened to by a human, I doubt there'd be a problem.
