Visual Bank Launches Innovative Japanese Three-Speaker Conversation Dataset for AI Development

Visual Bank Introduces the Japanese Three-Speaker Audio Dataset



Visual Bank Inc., a Tokyo-based startup led by CEO Saneyuki Nagai, has officially launched the "Japanese Three-Speaker Speaker-Separated Daily Conversation Audio Corpus" through its Qlean Dataset initiative, developed by its subsidiary Amana Images Inc. This innovative dataset serves to facilitate training and improvement of AI systems in the realms of speech recognition, dialogue understanding, and voice-enabled applications.

Overview of the Dataset


The dataset captures authentic interactions among three speakers—a male customer, a female customer, and a female store clerk—set in a café environment. It is comprised of four distinct audio files, each isolating the speakers for clarity, while also providing a version where all participants are heard simultaneously. This structure makes it a versatile resource for various AI applications, including Automatic Speech Recognition (ASR) and generative AI.

The recordings feature natural speech patterns, including overlaps and environmental sounds, thus providing an excellent basis for testing the accuracy of ASR systems and dialogue generation models. With potential applications ranging from customer service chatbots to educational tools, this dataset represents a significant leap forward in the capabilities of conversational AI.

Use Cases


The use cases for the Japanese Three-Speaker Dataset are extensive:
1. Improving Speech Recognition and Speaker Separation Models: The diversity of conversation, complete with overlapping dialogues and varying intonations, allows developers to refine models for source localization and ASR, enhancing their performance in complex auditory scenarios.
2. Training Conversational AI for Natural Dialogue: By incorporating realistic conversation flows—including requests, confirmations, and natural interaction styles—this dataset can be invaluable for training customer support and chatbot systems, ensuring they respond appropriately in real-world situations.
3. Development of AI for Emotion Recognition: The nuances in speech, including tone variations between the clerk’s polite language and shifts in customer emotions, open up possibilities for advances in emotion-recognition technology and paralinguistic analysis.
4. Japanese Language Education Applications: For educational purposes, such as tools designed for non-native Japanese speakers, the dataset provides relatable and contextually rich conversational samples tailored for pronunciation practice and conversational training.
5. Strengthening Multimodal AI Capabilities: This dataset enhances the performance of Japanese language models and multimodal systems by supporting better understanding of conversation structures post audio-to-text conversion.

The AI Data Recipe Concept


Under the umbrella of Qlean Dataset, Visual Bank introduces its unique "AI Data Recipe," which emphasizes flexibility and customizability of datasets based on various application needs. This concept ensures that organizations can utilize ready-to-use data packs while being able to tailor them according to their specific research or commercial requirements. Partnerships with industry leaders and data partners, such as Chiba Lotte Marines, enhance the alignment of offerings with current market trends and needs.

The Qlean Dataset is prepared with full compliance with international privacy regulations and participant consent, ensuring a secure and legally sound environment for AI development. It aims to drastically reduce the overhead associated with data collection, thus facilitating quicker deployment and enhanced ROI for AI projects.
