Julius does not recognize anything I say while this is going on.\r\n\r\nI am running this on a RaspberryPi3 using ALSA for input through a USB microphone.  I found that Pulseaudio has too much overhead, probably due to process switching, to use on a RaspberryPi, and it introduces gaps.  So I am staying with ALSA.\r\n\r\nIf I stop Julius and restart it, sometimes the message do not recur.\r\n\r\nIn order to be decoupled from Julius, I run Julius in \"module\" mode and communicate over a TCP link.  It would be nice if there was a way to detect that this problem is happening besides just _not_ receiving recognition output."},"comment":{"url":"https://api.github.com/repos/julius-speech/julius/issues/comments/230341452","html_url":"https://github.com/julius-speech/julius/issues/31#issuecomment-230341452","issue_url":"https://api.github.com/repos/julius-speech/julius/issues/31","id":230341452,"user":{"login":"colbec","id":14130995,"avatar_url":"https://avatars.githubusercontent.com/u/14130995?v=3","gravatar_id":"","url":"https://api.github.com/users/colbec","html_url":"https://github.com/colbec","followers_url":"https://api.github.com/users/colbec/followers","following_url":"https://api.github.com/users/colbec/following{/other_user}","gists_url":"https://api.github.com/users/colbec/gists{/gist_id}","starred_url":"https://api.github.com/users/colbec/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/colbec/subscriptions","organizations_url":"https://api.github.com/users/colbec/orgs","repos_url":"https://api.github.com/users/colbec/repos","events_url":"https://api.github.com/users/colbec/events{/privacy}","received_events_url":"https://api.github.com/users/colbec/received_events","type":"User","site_admin":false},"created_at":"2016-07-04T18:52:47Z","updated_at":"2016-07-04T18:52:47Z","body":"@pdtwonotes I wonder if you perused an issue I raised earlier https://github.com/julius-speech/julius/issues/11 where \"no data fragment\" occurred; possibly not in a parallel context, but may be of assistance. Intuitively I think it means that Julius was expecting voice input from the system but just did not get it, due to any number of possible steps transmitting the data."}}
