The human voice is critical in recognizing the speaker's identity and gender. This study aims to develop an effective gender detection system using short utterances of less than one second. Wavelet Cepstral Coefficient (WCC) features were used for feature extraction, and a Long Short-Term Memory (LSTM) model was applied for classification. Primary and secondary short voice datasets, including syllables and the Audio MNIST dataset, underwent acoustic pretreatment and were trained using LSTM architectures with 32, 64, and 128 units. Results indicated that the LSTM model achieved high accuracy, with the syllable dataset reaching 0.99 accuracy and the Audio MNIST dataset showing perfect accuracy (1.00) using a 32-unit configuration. The findings demonstrate that combining WCC features and LSTM models can efficiently handle short-duration speech for accurate gender detection. © 2024 IEEE.
