valid key with ask

[neera...@gmail.com]

 Is it possible to implement "valid keys" feature with ask , within current set of features

so if validkeys="123"  and limit=1

I can skip anything pressed other then "1" "2" or "3" within timeout values.

it implies array, if you have it as a string, you can turn it to array like so: '123'.split

What you're asking for is hotword detection, which we do not currently support. Please feel free to file a feature request on github. Currently the Adhearsion-ASR plugin implements some of the things required for this, but does not do hotword detection, but rather will fire a nomatch if you go out of grammar.

what about do block in 'ask' . Can I reset buffer metadata, so that for an invalid keypress  limit will still be applicable.

 validkeys = '123'

 ask limit:1 do |buffer|

    if validkeys.include? buffer[-1,1]

       # do something which will cease ask from exiting unless a valid key is pressed

    end

end

currenty this ask will exit with first press of any key.

This will match 1,2,3, otherwise throw a nomatch:

validkeys = '123'

ask limit: 1 do |buffer|

  validkeys.include? buffer

end

This is not hotword detection like I think you were asking for. It will not ignore other keypresses, it will terminate as a nomatch.
