Qlean Dataset Launches New Japanese Speech Dataset

Visual Bank Inc., based in Minato-ku, Tokyo and led by CEO Saneyuki Nagai, has unveiled an innovative resource for AI development: the Qlean Dataset. Through its subsidiary, amanaimages Inc., this dataset focuses on enhancing Automatic Speech Recognition (ASR), Natural Language Processing (NLP), and Large Language Models (LLMs) by providing a structured corpus specifically for the Japanese language.

Overview of the Qlean Dataset

The Qlean Dataset now features a new entry: the Japanese Single-Speaker Scripted Read Speech Corpus with Transcripts. This dataset provides voice recordings from a male native Japanese speaker reading from prepared scripts, and it comes complete with transcriptions that accurately represent the spoken material.

This meticulous collection offers clear audio and text correspondence, making it invaluable for the development of AI systems where precision in speech-to-text alignment is paramount. With a structured format, the dataset minimizes the typical disfluencies associated with spontaneous speech, such as self-corrections or topic shifts, allowing users to focus on clean, accurate data for AI training and evaluation tasks.

Use Cases

Research and Benchmarking

In research environments, this dataset can function as a robust tool for evaluating Japanese ASR models’ recognition accuracy and error tendencies. The clearly defined audio and text relationship aids researchers in identifying performance gaps and refining their models accordingly.

Industrial Applications

In industry, the dataset serves as a crucial training resource for validating language processing pipelines that include voice input capabilities. By integrating the accurate transcripts with speech recognition outputs, it enables businesses to enhance their processing systems, ensuring higher efficiency and reliability.

Educational Use

Furthermore, the dataset is suitable for educational applications. Instructors can use it to teach the fundamentals of speech recognition and audio processing, while students can practice with a verified set of data to understand model operations and comparative assessments of existing frameworks.

Technical Specifications

• - Data Type: Audio and Text
• - Attributes: Features Japanese male speakers
• - Data Format: Audio in MP3, texts in TXT, JSON, and CSV formats
