In this study, researchers explored the realm of Speech Emotion Recognition (SER) to determine its language-independence. Utilizing Bangla and English languages, they assessed the feasibility of distinguishing emotions from speech regardless of linguistic differences. The emotions under scrutiny included happiness, anger, neutral, sadness, disgust, and fear. Three Emotional Speech Sets were employed for investigation: two crafted by native Bengali speakers in both languages and one developed by native English speakers from Canada. Meticulously selected language-independent prosodic features were analyzed using a Support Vector Machine (SVM) model for classification purposes. Three distinct experiments were conducted to test the hypothesis: evaluating individual speech sets' performance, combining them for unified context classification rate measurement, and training/testing with different sets for comprehensive recognition rate assessment. Findings suggested that SER is predominantly language-independent; however, discrepancies were noted in recognizing disgust and fear across Bangla and English languages. Non-native speakers are capable of conveying emotions through speech similar to their native tongue expression. Detailed insights into methodology revealed vocal feature extraction via Praat software's signal processing techniques. Language-independent prosodic features such as pitch median/mean/standard deviation/intensity captured emotional nuances within speech patterns significantly aiding analysis. This study sheds light on intricate interplay between language/emotion recognition in speech processing systems while underscoring potential cross-linguistic applicability in SER research endeavors.

SummaryResearchers studied how computers can understand emotions in speech without being limited by language. They looked at different emotions like happiness, anger, and sadness. People from Bangladesh and Canada spoke to help with the research. The researchers used a computer model to analyze the way people speak when they are emotional. They did experiments to see how well the computer could recognize emotions in different languages. Definitions- Speech Emotion Recognition (SER): The ability of computers to understand emotions conveyed through speech. - Language-independence: Not being limited by a specific language. - Prosodic features: Aspects of speech such as pitch, intensity, and rhythm that convey emotion. - SVM model: Support Vector Machine model used for classification tasks in machine learning. - Discrepancies: Differences or inconsistencies observed.

Speech Emotion Recognition (SER) is a rapidly growing field of research that aims to develop systems capable of recognizing and interpreting emotions from speech. With the increasing use of voice-based technologies in various applications, such as virtual assistants and customer service, the need for accurate emotion recognition has become more crucial. However, most existing SER systems are limited to specific languages, making them less effective in cross-linguistic scenarios. In this study, researchers explored the language-independence of SER by analyzing Bangla and English languages' emotional speech sets.

The study aimed to determine whether emotions can be accurately recognized from speech regardless of linguistic differences. The six basic emotions under scrutiny were happiness, anger, neutral, sadness, disgust, and fear. To achieve this goal, three Emotional Speech Sets were utilized: two crafted by native Bengali speakers in both languages and one developed by native English speakers from Canada.

To assess the feasibility of distinguishing emotions from speech across different languages, meticulously selected language-independent prosodic features were analyzed using a Support Vector Machine (SVM) model for classification purposes. Three distinct experiments were conducted to test the hypothesis: evaluating individual speech sets' performance, combining them for unified context classification rate measurement, and training/testing with different sets for comprehensive recognition rate assessment.

The findings suggested that SER is predominantly language-independent; however, discrepancies were noted in recognizing disgust and fear across Bangla and English languages. This indicates that while some emotions may be universally expressed through speech regardless of language barriers (such as happiness or anger), others may have cultural or linguistic influences on their expression (such as disgust or fear). These results highlight the importance of considering cultural nuances when developing cross-linguistic SER systems.

One interesting finding was that non-native speakers are also capable of conveying emotions through speech similar to their native tongue expression. This challenges previous assumptions that only native speakers can accurately express emotions through speech.

A detailed analysis of methodology revealed vocal feature extraction via Praat software's signal processing techniques. This involved extracting language-independent prosodic features such as pitch median, mean, standard deviation, and intensity from the speech samples. These features were then used to train the SVM model for emotion classification.

The study's results shed light on the intricate interplay between language and emotion recognition in speech processing systems. It also underscores the potential cross-linguistic applicability of SER research endeavors. By utilizing a diverse set of languages and emotional speech sets, this study provides valuable insights into developing more robust and accurate cross-linguistic SER systems.

In conclusion, this research paper contributes to the growing body of knowledge on Speech Emotion Recognition by exploring its language-independence through an extensive analysis of Bangla and English languages' emotional speech sets. The findings suggest that while SER is predominantly language-independent, cultural and linguistic influences may impact some emotions' expression through speech. This study highlights the importance of considering these factors when developing cross-linguistic SER systems for real-world applications.
