TheRuSLan: Database of Russian Sign Language (2020.lrec-1)
Copied to clipboard
| Challenge: | The database is the first of a kind for Russian sign language and is intended for use in machine learning, gesture recognition and sign language linguistics. |
| Approach: | They present a Russian sign language multimedia database called TheRuSLan . the database includes lexical units from Russian sign languages within one subject area . |
| Outcome: | The proposed database includes lexical units from Russian sign language within one subject area. |
RUSAVIC Corpus: Russian Audio-Visual Speech in Cars (2022.lrec-1)
Copied to clipboard
| Challenge: | a new audio-visual speech corpus is recorded in a car environment and is noise-robust . currently there is no noiserobustic speech recognition system to be used in real-driving conditions. |
| Approach: | They propose to use a natural speech corpus recorded in a car environment to improve audio-based speech recognition in the presence of severe acoustic noise. |
| Outcome: | The proposed corpus is natural, controlled and adequate size to train state-of-the-art NN approaches. |
Class-based LSTM Russian Language Model with Linguistic Information (2020.lrec-1)
Copied to clipboard
| Challenge: | LSTM models can be used in speech recognition systems at N-best or lattice rescoring stage. |
| Approach: | They propose to use word frequency and linguistic information to generate class-based LSTM Russian language models with various numbers of classes. |
| Outcome: | The proposed models outperform word-based models and word2vec models in terms of perplexity, training time, and word error rate. |
