Yeah, with Codec 2 setting the gold standard, I don't find this very impressive. I find this more intelligible at one-third of the Lyra bitrate: http://www.row

I find this more intelligible at one-third of the Lyra bitrate: http://www.rowetel.com/downloads/codec2/hts2a_1300.wav http://www.rowetel.com/downloads/codec2/hts2a_1300.wav Codec 2 does a better job of isolating the parts of sound which are most necessary to intelligible speech, without necessarily caring too much about preserving the original qualities of the speaker's voice or environment. Fun fact: Codec 2 can be used to transmit voice over IRC: https://github.com/asiekierka/voirc https://github.com/asiekierka/voirc

I had to listen to your wav sample 4 times before understanding what it was saying... To me, that isn't intelligible... Perhaps with practice one could learn to understand it, but that isn't really what I want from my audio codec.

  The biggest challenge with evaluating all of these, is that once you've listened to a comprehensible version of one of these samples, they all sound more intelligible. I had problems with the example too. After hearing the original it's now easy. It makes it really hard to properly assess the intelligibility for developers without decent sized panels of people to help evaluating them.

Completely unrelated but damn so they need to update the illustration at the top of that page. It's hideous.

Could not understand that sample at all, I don't think this makes your point.

It's definitely impressive but your ears are broken if you think that is more intelligible.

  Or maybe they are visually impaired. I'm always impressed when I sit next to a blind person in a train and hear them using a smartphone. The screen readers run at 2x normal speed (at least) and to my untrained ears the robotic noises just sound like a garbled mess instead of intelligible speech. The blind person using the phone, however, seems to have no problem understanding it. Fascinates me every time.
