Abstract
</h3>
<p class="text-justify">
We present OOD-Speech, the first out-of-distribution
(OOD) benchmarking dataset for Bengali automatic
speech recognition (ASR). Being one of the most spo-
ken languages globally, Bengali portrays large diversity
in dialects and prosodic features, which demands ASR
frameworks to be robust towards distribution shifts. For
example, islamic religious sermons in Bengali are deliv-
ered with a tonality that is significantly different from
regular speech. Our training dataset is collected via mas-
sively online crowdsourcing campaigns which resulted in
1177.94 hours collected and curated from 22, 645 native
Bengali speakers from South Asia. Our test dataset com-
prises 23.03 hours of speech collected and manually anno-
tated from 17 different sources, e.g., Bengali TV drama,
Audiobook, Talk show, Online class, and Islamic sermons
to name a few. OOD-Speech is jointly the largest pub-
licly available speech dataset, as well as the first out-of-
distribution ASR benchmarking dataset for Bengali.

<h3>
Project Details
</h3>
<p class="text-justify">
This is the largest publicly available speech recognition corpus for Bengali. The data crowdsourcing started at 21st Feb 2022 and still ongoing.
The data contributors come from all walks life and the dataset has representative samples from different demographic strata and domains (gender, regional accent, age, background noise etc).
The test data comprises of challanging samples from different types of scripted and spontaneous speech recordings.
A Kaggle community research competition based on an earlier version of this dataset won the Kaggle Community Competition Award for the month of July, 2022.
Currently a dedicated team is extending the dataset to include representative samples for the different major regional dialects of Bengali. More big news coming!! Stay tuned.

A naive baseline (left) combining mip-NeRF 360 and Instant NGP results in aliasing as the camera moves laterally. Our full method (right) produces prefiltered renderings that do not flicker or shimmer.

<p class="text-justify">
The proposal network used for resampling points along rays in mip-NeRF 360 results in an artifact we refer to as <em>z-aliasing</em>, where foreground content alternately appears and disappears as the camera moves toward or away from scene content. Z-aliasing occurs when the initial set of samples from the proposal network is not dense enough and misses thin structures, such as the chair above. Missed content can not be recovered by later rounds of sampling, since no future samples will be placed at that location along the ray. Our improvements to proposal network supervision result in a prefiltered proposal output that preserves the foreground object for all frames in this sequence. The plots above depict samples along a ray for three rounds of resampling (blue, orange, and green lines), with the y axis showing rendering weight (how much each interval contributes to the final rendered color), as a normalized probability density.
