+
+## What's in a name
+
+- വിസ്താരം
+- Vistaar(विस्तार) meaning broad in Hindi
+- We propose collation of benchmarks across languages and domains/types of data. We call this Vistaar (meaning broad in Hindi) and it comprises of
+publicly available benchmarks across 12 languages, leading to 59 computed WER values across benchmarks and languages.
+
+## Abstract of paper
+
+- Improving ASR systems is necessary to make new LLM-based use-cases accessible to people across the globe. 
+
+- In this paper, we focus on Indian languages, and make the case that diverse benchmarks are required to evaluate and improve ASR
+systems for Indian languages.
+
+- To address this, we collate Vistaar as a set of 59 benchmarks across various language and domain combinations, on which we evaluate 3 publicly available ASR systems and 2 commercial systems.
+
+## Abstract of paper
+
+- We also train IndicWhisper models by fine-tuning the Whisper models on publicly available training datasets across 12 Indian languages
+totalling to 10.7K hours.
+
+- We show that IndicWhisper significantly improves on considered ASR systems on the Vistaar benchmark.
+
+- Indeed, IndicWhisper has the lowest WER in 39 out of the 59 benchmarks, with an average reduction of 4.1 WER.
+
+- We open-source all datasets, code and models : https://github.com/AI4Bharat/vistaar
+
+## Interspeech conference
+
+- Selected for this.
