Nishika Introduces 'shirushi-defense' Voice Recognition Model

Nishika Inc., located in Shinagawa, Tokyo, has recently launched an innovative voice recognition model specifically designed for the defense and aerospace industries. Known as 'shirushi-defense', this new model is available as a limited-time free option within the SecureMemo application, enhancing the efficiency of meeting minutes and technical reports in these specialized fields.

A Focused Approach to Specialized Terminology

The 'shirushi-defense' model builds on Nishika's proprietary voice recognition technology and incorporates a refined vocabulary set tailored for the defense and aerospace sectors. This 4,000-word lexicon was developed through the analysis of publicly available resources such as the Defense White Paper, aviation law, and various glossaries from the Japan Society of Mechanical Engineers.

Traditionally, voice recognition systems struggled with the intricate and highly specialized terms used in defense and aviation discussions. Commonly, items like the names of equipment, ranks, and specific terminology in materials science and fluid mechanics were often misinterpreted, leading to lengthy revisions of meeting records. Thus, developing this model aims to bridge the 'language barrier' prevalent in these fields.

Addressing Unique Challenges

Unlike the medical sector, which benefits from a unified standard terminology dictionary, the defense and aerospace industries lack such resources. This reality presents substantial difficulties, as no centralized glossary exists for industry-specific terms. Nishika recognized this gap and formulated a comprehensive dictionary by extracting and standardizing slang, jargon, and terminologies from various open data sources, ensuring that variations in writing and pronunciation were minimized before retraining their voice recognition model.

Improvements and Performance Metrics

In evaluations using a custom-built audio dataset that includes defense and aviation terminology, the model has demonstrated significant improvement. The noun word error rate (noun-WER) decreased from 18.6% to 8.2%, resulting in an error reduction of approximately 56%. Moreover, the character error rate (CER) dropped by 63.6%, showcasing the model's effectiveness.

Crucially, despite its specialization, 'shirushi-defense' maintains comparable accuracy for general business meetings. Typically, specialized training models suffer from a phenomenon called 'catastrophic forgetting,' wherein improvements in one area lead to declines in another. However, this model is designed to retain its discerning quality for standard business discussions, achieving a 44.7% reduction in CER for evaluation tests of regular meeting audio.

Access and Usage of 'shirushi-defense'

To celebrate the launch, Nishika is offering this advanced model as a complimentary feature within the SecureMemo tool, specifically for defense and aerospace stakeholders seeking to experience its capabilities. SecureMemo operates in a local environment disconnected from external networks, ensuring that sensitive meeting contents remain internal, allowing for secure transcription and summarization.

Interested parties can take advantage of a free trial, easily accessible through Nishika's inquiry form or by contacting the sales team directly.

How SecureMemo Works

SecureMemo is an on-premise AI voice transcription software that emphasizes security, allowing audio data to be processed and stored safely, insulated from outside access. The software boasts a remarkable transcription accuracy rate of 96.2%, thanks to the advanced shirushi voice recognition AI, which functions well even amidst noise and unclear audio signals. It also facilitates auto-generating topic-based summaries and decision highlights in real time.

In addition to these features, SecureMemo supports transcription and translation across approximately 100 languages, enabling smooth interactions during multilingual meetings or collaborations with overseas branches. The service is designed with a seamless user experience in mind.

Nishika's vision revolves around leveraging technology to cultivate a society where everyone can take pride in their work, striving to create valuable data assets that enhance corporate productivity. The signature product, SecureMemo, seeks to transform business meetings into structured data, aiming for high-value information utilization in Japanese companies.
