Exactly. This is also why Google sponsors the CHiME challenge, the existence of which is more proof that ASR is pretty far from solved. http://spandh.dcs.shef.

- dharma1 9y agoGood stuff. Was looking into cheap array mics with linux drivers a few times in the past but not much is available. Speech separation - Mitsubishi Research has done some pretty impressive stuff on that - http://www.merl.com/demos/deep-clustering http://www.merl.com/demos/deep-clustering. Haven't seen equivalents of that in open source ASR
- adrianbg 9y agoTotally. You may want to take a look at the papers from CHiME4 for more along those lines: http://spandh.dcs.shef.ac.uk/chime_challenge/chime2016/results.html http://spandh.dcs.shef.ac.uk/chime_challenge/chime2016/resul... I'm really fascinated by the whole idea of blind source separation and the fact that speech signals are "sparse" in frequency space. We've had a similar experience looking for hardware / open source beamforming. There's a package called beamformit, but I think it's pretty old.
- j_s 9y agoThis is the useful info I've seen hardware-wise recently: https://medium.com/snips-ai/benchmarking-microphone-arrays-respeaker-conexant-microsemi-acuedge-matrix-creator-minidsp-950de8876fda https://medium.com/snips-ai/benchmarking-microphone-arrays-r... https://developer.amazon.com/alexa-voice-service/dev-kits/conexant-4-mic/ https://developer.amazon.com/alexa-voice-service/dev-kits/co... Amazon's 7-mic hardware has its own OEM program.
