We are much better at faces than we are at voices:
• Imagine I show you 10 photos of faces. Then I come back 15 minutes later and ask you to pick them out from a set of 20 faces.
• Imagine I play you 10 audio snippets of someone talking. Then I come back 15 minutes later and ask you to pick them out from a set of 20 audio snippets of people talking.
That said, I agree with you that primarily this technology would be useful for surveillance.
If you can zoom in on any given conversation happening at New York Penn Station, you're basically in the Bourne Identity, with all the privacy-destroying overreach that entails.
- mlthoughts2018 6y agoI think you completely missed the point. If you think the overall fact that humans are better at face identification than audio identification is relevant here, you missed the point, since that high level fact is not related to this specific problem or the comparison being made.
- sillysaurusx 6y agoCan you explain the point? Because I've missed it too.
- mlthoughts2018 6y agoThe task of disambiguating speakers, relative to skill at other audio processing tasks, is more similar to disambiguating superimposed faces, relative to skill at other vision tasks. It is not similar to quickly recognizing several different faces that are present in a video stream. Tasks requiring simultaneous processing of focused attention on multiple input streams are not very related to human visual or audio processing. These types of tasks are not similar to attending to things in peripheral vision or peripheral audio.
- sillysaurusx 6y agoI'd fail task #1 but excel at task #2. I have audio playing in my head constantly. It's how I learn about the world. It also seems to be inverted from when I was younger; visuals were much more vivid then.
- dillonmckay 6y agoSame, I can often identify actors on tv shows or movies by their voice, some of which is 20 to 30 years older or later than when I originally heard the voice.
