BanglaSER is a specialized dataset designed for the task of Bangla speech emotion recognition. This dataset includes a rich collection of speech-audio recordings that capture a variety of fundamental human emotions. It is curated to support research and development in the field of speech emotion recognition, particularly for the Bangla language, and is suitable for various deep learning architectures.

Dataset Composition:

• Total Number of Recordings: 1,467
• Number of Speakers: 34 (17 male and 17 female)
• Age Range of Speakers: 19 to 47 years
• Recording Devices: Smartphones and laptops

Emotional States Covered:

• Angry
• Happy
• Neutral
• Sad
• Surprise

Recording Structure:

Each emotional state is represented by:

• 3 Statements spoken three times by each participant.
• For Angry, Happy, Sad, and Surprise: 3 statements × 3 repetitions × 34 speakers = 1,224 recordings.
• For Neutral: 3 statements × 3 repetitions × 27 speakers = 243 recordings

Key Features:

Balanced Representation:

• The dataset is carefully balanced with an equal number of male and female participants, ensuring that the recordings reflect diverse voices and emotional expressions.
• Emotions are evenly distributed across the dataset, providing a robust basis for training and evaluating emotion recognition models.

Realistic Recording Conditions:

• Recordings are made using commonly available devices, such as smartphones and laptops, which helps in preserving the naturalistic quality of the audio.
• The dataset reflects real-life acoustic environments, making it more applicable to real-world applications.

Deep Learning Compatibility:

• BanglaSER is designed to be compatible with various deep learning architectures, including Convolutional Neural Networks (CNNs), Long Short-Term Memory Networks (LSTMs), and Bidirectional LSTMs (BiLSTMs).
• The dataset can be used for a range of tasks, from emotion classification to sentiment analysis, and more.

Usage and Applications:

• Emotion Recognition Models: BanglaSER provides a diverse set of recordings that are ideal for training models to recognize and classify emotions in Bangla speech.
• Benchmarking and Evaluation: The dataset serves as a benchmark for evaluating the performance of emotion recognition systems and can help in comparing different model architectures and techniques.
• Research and Development: Researchers can use BanglaSER to explore new methods in speech emotion recognition, develop novel algorithms, and enhance the understanding of emotion in speech.
