AI researcher at Khoja Akhmet Yassawi International Kazakh–Turkish University who evaluated WavLM-Large for Kazakh child speech disorder detection.
KazakhstanWhat I'm looking for
At Khoja Akhmet Yassawi International Kazakh–Turkish University, I research AI for low-resource speech technology and teach machine learning and neural networks. My doctoral research focuses on detecting and classifying speech sound disorders in Kazakh-speaking children.
For this research, I audited a corpus of more than 5,000 child speech recordings and metadata records. I developed and benchmarked WavLM-Large and other classifiers, using subject-independent partitions to reduce child and speaker leakage.
In a three-class test covering lambdacism, rhotacism, and sigmatism, my WavLM-Large-based system achieved 79.07% accuracy, 79.44% balanced accuracy, and 78.97% macro-F1. These are experimental results, not clinical diagnostic performance.
My published research also covers deepfake voice detection, accessible speech technology, recyclable-waste recognition, and environmental computer vision. I contribute to an AI-supported gamified digital environment for personalized natural-science education and participate in the eVoiceNet research network.
