Whispered Speech Emotion Recognition with Gender Detection using BiLSTM and DCNN

Emotions are human mental states at a particular instance in time concerning one’s circumstances, mood, and relationships with others. identifying emotions from the whispered speech is complicated as the conversation might be confidential. the representation of the speech relies on the magnitude of its information. whispered speech is intelligible, a low-intensity signal, and varies from normal speech. emotion identification is quite tricky from whispered speech. both prosodic and spectral speech features help to identify emotions. the emotion identification in a whispered speech happens using prosodic speech features such as zero-crossing rate (zcr), pitch, and spectral features that include spectral centroid, chroma stft, mel scale spectrogram, mel-frequency cepstral coefficient (mfcc), shifted delta cepstrum (sdc), and spectral flux. there are two parts to the proposed implementation. bidirectional long short-term memory (bilstm) helps to identify the gender from the speech sample in the first step with sdc and pitch. the deep convolutional neural network (dcnn) model helps to identify the emotions in the second step. this implementation is evaluated using the wtimit data corpus and gives 98.54% accuracy. emotions have a dynamic effect on genders, so this implementation performs better than traditional approaches. this approach helps to design online learning management systems, different applications for mobile devices, checking cyber-criminal activities, emotion detection for older people, automatic speaker identification and authentication, forensics, and surveillance.
