Likelihood Ratio – Result from statistical test for two models comparation. It gives back number which expresses how many times more likely the data are under one model than the other. LR meets numbers in interval <-∞;+∞>

Language Print Archive - pack of language prints from the recordings spoken in the same language/dialect. Used for the language identification in LID comparison.
Language Print - output data from LID technology
Features – FEA is optional output from KWS technology. Looking for keywords in FEA is faster than in original recording.
Distribution of audio and video content to a dispersed audience via any audio or visual mass communications medium, but usually one using electromagnetic radiation (radio waves)
A: Via HTTP header “Accept” parameter (application/json; application/xml) Via request query “format=json/xml” If the format is not defined (or the HTTP header "Accept" parameter has one of these values: application/*,*/*,*), server will return json.
A: From the utilities in the package, you can find it in "ffprobe <file_name>", it will write out the info about the file. *Utility "ffprobe" is not included in our package(s). It is part of ffmpeg (https://ffmpeg.org/ffprobe.html) and it is neccessary to install it separately.
A: The following is recommended: For adding new language to language pack 20+ hours of audio for each new language model (or 25+ hours of audio containing 80% of speech) Only 1 language per record For adapting the existing language model (discriminative training) 10+ hours of audio for each language May be done on customer site. May be done in Phonexia using anonymized data (= language-prints extracted from a .wav audio)
A: The language-prints do not depend on the current language pack used. You may use them for both training a new language pack and testing/comparing against an existing language pack. The language-prints needs to be compatible only with the model of LID used for language-print extraction.
