AI Audio Production Studio 'Koeroku' Begins Development of Multi-language Support

SynergyAI, a developer of industry-specific AI solutions, has announced that its AI audio program production studio, 'Koeroku,' has begun the development of multi-language support.

While Koeroku currently specializes in generating AI radio programs in Japanese, the company is advancing development to expand its supported languages to meet the growing needs for overseas content production, global corporate PR, and multi-language educational materials.

Background of Development

Since the release of the beta version in May 2026, Koeroku has been utilized by content creators, streamers, and corporate PR professionals. As its usage has spread, there have been increasing requests to produce programs in other languages, such as English and Chinese.

In response to these demands for audio production in languages other than Japanese—such as for international podcasts, global PR, and multi-language educational content—the company has commenced development of multi-language support.

Areas of Development

・Script generation supporting multiple languages

・Script structures aligned with the speech patterns and honorific expressions of each language

・AI voice synthesis supporting multiple languages

・Adjustment of program styles for each language

Future Outlook

Specific supported languages and their availability will be announced sequentially based on development progress. SynergyAI intends to evolve Koeroku into an AI audio program production studio used not only in Japan but globally.
