Re-arranged the information a bit for OK GOOGLE. I think this better aligns with our current conventions. Cog = Manage Voice and Audio Activity

@dpapad is this something you could add to Search? Please mark as Available if not.

I am currently working on the "About" page, and the plan is to work on "search within settings" after that. Marking as available for now.

 Issue 630078  has been merged into this issue.

bettes@ - Should the icon for the "Voice and Audio Activity" link be the icon-external image (e.g. like for Wallpaper)?

+bettes@

Also, please confirm that we want to eliminate the "learn more" link.

Also:

* There is a "Retrain voice model" link that shows up when OK Google is enabled.
* There is an error indicator icon with the following possible error messages. (I do not know how to trigger any of theses):
  This feature is temporarily unavailable. <Help>
  <Native Client plugin> needs to be enabled to use this feature.
  Microphone is currently unavailable. <Manage microphone>

MD Settings: Add Hotword (OK Google) section to search_page

The Hotword/OK Google section in the existing UI is... fragile.
This is an attempt to simplify and implement the UI without breaking
any existing functionality.
It would benefit from a re-implementation, ideally ising the
existing hotwordingPrivate API (which would may need to be expanded).

fukino@ - can you add the "Show Google Now cards in the launcher" section to MD Settings? Thanks!

(That is the "google-now-launcher" section in browser_options.html)

No longer blocking  issue 614589  since "Show Google Now cards in the launcher" is experimental.

This is a launched feature, we need to keep this blocking dev.

dbeam@ looked through it, and it seems to be 100% enabled for Chrome OS en-US / en-GB users on all channels (as well as for all Googlers).

fukino@, any update on this?

I'm sorry I didn't realize this is a blocker.
I think I can send a CL tomorrow.

Hi dbeam@,
How can I enable Google Now launcher in developer build?
I built the latest Chrome and pushed it to chell, but I don't see "Show Google Now cards in the launcher" section in chrome://settings.
Language is en-US, and base::FieldTrialList::FindFullName("GoogleNowExtension") returns empty string.

maybe try adding to testing/variations/fieldtrial_testing_config.json?

Thank you for the suggestion!
I was able to see the Google Now cards by adding following lines to testing/variations/fieldtrial_testing_config.json and use chromium(not chrome) build.

    "GoogleNowExtension": [
      {
        "platforms": [
          "chromeos"
        ],
        "experiments": [
          {
            "name": "Enable",
            "params": {
              "id": "mnfadmojomeniojkkikjpgjaegolkbpb"
            }
          }
        ]
      }
    ],
