Overview

What's inside EmoTa

EmoTa comprises 936 recorded utterances from 22 native Sri Lankan Tamil speakers, each articulating 19 semantically neutral sentences across five primary emotions. Speakers represent dialects from the northern, eastern, western, and central provinces, and inter-annotator agreement reached a substantial Fleiss' κ of 0.74.

Speakers

22 native speakers

Balanced by gender — 11 male, 11 female — spanning four regional Sri Lankan Tamil dialects.

Emotions

Five emotions

Anger, happiness, sadness, fear, and neutrality, elicited under a consistent protocol.

Prompts

19 neutral sentences

Semantically neutral prompts reduce lexical bias so the signal is emotion, not wording.

Recording

Studio quality

Captured in a controlled, soundproof environment with professional equipment.

Scale

~48 minutes

Compact yet balanced coverage across every speaker, emotion, and sentence.

Benchmark

0.91 F1 baseline

XGBoost and Random Forest baselines reach 0.91 and 0.90 F1 on emotion classification.

Dataset loader

Load EmoTa in two lines of Python

The emota_loader package on PyPI parses the corpus into typed samples with speaker, region, transcript, and emotion fields.

Install

bash
$ pip install emota_loader

Get the audio first. Download the dataset from Hugging Face, then point the loader at its root directory.
