- Abstract summary: We study training a single end-to-end (E2E) automatic speech recognition (ASR) model for three languages used in Kazakhstan: Kazakh, Russian, and English.
We first describe the development of multilingual E2E ASR based on Transformer networks and then perform an extensive assessment on the aforementioned languages.

- Abstract: We study training a single end-to-end (E2E) automatic speech recognition
(ASR) model for three languages used in Kazakhstan: Kazakh, Russian, and
English. We first describe the development of multilingual E2E ASR based on
Transformer networks and then perform an extensive assessment on the
aforementioned languages. We also compare two variants of output grapheme set
construction: combined and independent. Furthermore, we evaluate the impact of
LMs and data augmentation techniques on the recognition performance of the
multilingual E2E ASR. In addition, we present several datasets for training and
evaluation purposes. Experiment results show that the multilingual models
achieve comparable performances to the monolingual baselines with a similar
number of parameters. Our best monolingual and multilingual models achieved
20.9% and 20.5% average word error rates on the combined test set,
respectively. To ensure the reproducibility of our experiments and results, we
share our training recipes, datasets, and pre-trained models.

Cross-lingual self-supervised visual representation learning has been a growing research topic in the last few years.
We use the recently-proposed Raw Audio-Visual Speechs (RAVEn) framework to pre-train an audio-visual model with unlabelled data.
Our experiments show that: (1) multi-lingual models with more data outperform monolingual ones, but, when keeping the amount of data fixed, monolingual models tend to reach better performance.
