LVCSR

Large Vocabulary Continuous Speech Recognition

LLR

Log-Likelihood Ratio – Logarithmic function of LR (le)

LR

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 <-∞;+∞>

LPA

Language Print Archive – pack of language prints from the recordings spoken in the same language/dialect. Used for the language identification in LID comparison.

LP

Language Print – output data from LID technology

LM

Language Model (“vocabulary” in STT technology)

LID

Phonexia Language Identification, multiple generations available marked by version like LIDv2 or LIDv3

LEA

Law Enforcement Agency

LDC

Linguistic Data Consortium (Fisher English etc.) – Group of libraries, universities,… working with speech data.

KWS

Phonexia Keyword Spotting – acoustics based ASR, several technologies possible, language dependent

IVR

Interactive Voice Response – Process of caller authentication (typically banking segment)

iVector

iVector – Unique value representing specific group of voice tracks. Consist of 600 values, usually lowered to low dimensional vector (200 values)

ISS

FtRT

Faster than the Real Time – processing speed on 1 instance of the speech technology. Can be described also as “X min of audio archive to be processed in Y min of the real time”.

FRR

False Rejection Ratio – Values, which were not accepted, when they were supposed to be accepted, aka ‘misses’

FEA

Features – FEA is optional output from KWS technology. Looking for keywords in FEA is faster than in original recording.

FAR

False Acceptance Ratio – Values, which are accepted values, when there were not supposed to be accepted, aka ‘false alarms’
