Automatic speech recognition (ASR) technologies for Latvian have a relatively short history because even three years ago (i.e., in 2013 and before) there was no orthographically annotated speech corpus, which could be used for ASR purposes, available.
there have been attempts to develop ASR systems for broadcast speech recognition (Oparin et al, 2013) in the Quaero project (Lamel, 2012) using acoustic model bootstrapping.
