Many useful things are available on the internet in English, but not everyone understands English well. So, we often need to translate these things into local languages to help people who don't speak English. But doing this translation by hand is hard, expensive, and takes a long time. That's where machine translation comes in – it's a way for computers to automatically change text from one language to another without people having to do it. Among the different ways computers can do this, there's one called neural machine translation (NMT), which is really good at it. In this research paper, we talk about using NMT for two complicated Indian languages: English-Tamil and English-Malayalam. These languages are tricky because they have lots of unique features, and there aren't many online tools to help with translations. To make this work, we came up with a new way of using NMT. We added something called Multihead self-attention and used special pre-trained techniques called Byte-Pair-Encoded (BPE) and MultiBPE embeddings. These fancy words might sound complicated, but they help our system handle words it doesn't know well (Out Of Vocabulary or OOV words). We also collected texts from different places, fixed problems in the data we found online, and made it all better for our system to use. To check how well our system worked, we used something called the BLEU score. And guess what? Our system did really well! It got high scores of 24.34 for English-Tamil and 9.78 for English-Malayalam translations. That's better than what Google Translator could do, which got scores of 9.40 and 5.94 for the same translations.
