Existing speech signal processing technologies are inadequate for most noisy or degraded speech signals that are important to military intelligence. The Robust Automatic Transcription of Speech (RATS) program is creating algorithms and software for performing the following tasks on potentially speech-containing signals received over communication channels that are extremely noisy and/or highly distorted: Speech Activity Detection, Language Identification, Speaker Identification and Key Word Spotting.

Description in Czech
Existující technologie zpracování řečového signálu jsou nedostačující pro většinu hlučných nebo degradovaných řečových signálů, které jsou důležité pro vojenskou špionáž. Program robustní automatické transkripce řeči vytváří algoritmy a software, které provedou následující úkony na signálech potenciálně obsahujících řeč, které byly získány prostřednictvím komunikačních kanálů, jež jsou extrémně hlučné a/nebo vysoce deformované: detekce řečové aktivity, rozpoznávání jazyka, rozpoznávání mluvčího a detekce klíčových slov.

Keywords
speech recognition, speaker recognition, language recognition, keyword spotting, robustness, noise, transmission channels

Key words in Czech
rozpoznávání řeči, rozpoznávání mluvčího, rozpoznávání jazyka, detekce klíčových slov, robustnost, šum, přenosové kanály
