New Features: Sync Playback & Action Function (Beta)
June 8, 2025

Thank you for using Mojiokoshi-san. We are pleased to announce the release of new features.
1. Audio and Text Synchronization Playback
When you perform transcription while logged into Mojiokoshi-san, a new feature has been added that allows you to play and highlight block by block.
- PerfectVoice: Confirmation button per sentence
- AmiVoice: Confirmation button per speaker (if the number of speakers is set to 2 or more)
The transcription is divided into blocks by sentence or speaker, and each block has a play button.
Clicking the play button allows you to listen to the audio for that specific section.
Furthermore, sentences preceding the currently playing block are highlighted, making it easy to see your playback position at a glance.
2. Action Feature (β version)
When you select the "Actions" tab, buttons are created below the transcription result. You can perform actions by clicking these buttons.
Currently, this feature is in β version. It is a sample for users to try out during the service development phase before the official release.
This feature utilizes AI, and the action buttons vary depending on the transcription result.
The AI determines which button is most appropriate for the transcription result and automatically generates it.
Therefore, the same action buttons are not always guaranteed to appear.
Results are displayed within seconds, allowing for quick review.
Summary
A new summary feature has also been added.
Clicking the summary button will summarize the transcribed content into a few lines.
This is a convenient feature, so please give it a try.
About the AI for the Action Button Feature
The action buttons and summaries utilize the OpenAI, Inc. API.
Advanced natural language processing technology allows for quick extraction of key points from transcribed text.
To ensure your peace of mind, information sent via the OpenAI API is guaranteed not to be used for training purposes.
When using this service, the OpenAI, Inc. Terms of Use apply. Users agree to and shall comply with these terms. For more details, please see below:

We hope these new features will make your transcription work more comfortable and inspire new insights.
Please try out the updated features.
Mojiokoshi-san will continue to develop innovative features to meet your needs.
