A Dataset for Kazakh Emotional Text-to-Speech Synthesis</b></a></p>

<h2 align = "justify">Summary: </h2>
<p align = "justify">This study focuses on the creation of the KazEmoTTS dataset, designed for emotional Kazakh text-to-speech (TTS) applications.
KazEmoTTS is a collection of 54,760 audio-text pairs, with a total duration of 74.85 hours, featuring 34.23 hours delivered
by a female narrator and 40.62 hours by two male narrators. The list of the emotions considered include “neutral”, “angry”,
“happy”, “sad”, “scared”, and “surprised”. We also developed a TTS model trained on the KazEmoTTS dataset. Objective and
subjective evaluations were employed to assess the quality of synthesized speech, yielding an MCD score within the range of
6.02 to 7.67, alongside a MOS that spanned from 3.51 to 3.57. To facilitate reproducibility and inspire further research, we
have made our code, pre-trained model, and dataset accessible in our <a href = "https://github.com/IS2AI/KazEmoTTS/tree/master">GitHub repository</a>.</p>
