Kazakh language Text-to-Speech technology

Instructions for Kazakh TTS demo:

– Insert the Kazakh text inside the box below (Please use only Cyrillic alphabetic characters and punctuation marks, i.e. numbers and other special symbols should be written in textual forms. For better performance, split the long text into shorter segments.)
– Then click the “GET AUDIO” button
– The page will reload and you will find the Audio of your text under the box. Then press the Play button to listen to the Audio
We ask you to use the demo version of the project and the Kazakh text-to-speech project only for good purposes, not to use it for obscene speech, and also to comply with ethical norms.

In order to stimulate research and innovation and also encourage the use of Kazakh in the digital sphere, the Institute of smart systems and artificial intelligence (ISSAI) of Nazarbayev University conducted a Kazakh language speech synthesis project. Text-to-speech (TTS) conversion is the artificial production of human speech. It allows to convert the written text to the speech signal. TTS is an essential  component in many applications such as interactive smart assistant systems,  navigation systems, announcement systems and assistive technologies for the visually-impaired. It enables human-technology interaction without requiring visual and tactile interfaces.

To build Kazakh TTS systems, we used the KazakhTTS database developed by ISSAI. KazakhTTS is a high-quality open-source speech database which contains over 90 hours of audio recorded by professional speakers (male and female voices). The database is publicly available for both academic and commercial use upon request under Creative Commons Attribution 4.0 International License.
