IBM Voice Type was IBM speech-recognition software for Microsoft Windows. An M2I file contains language-related data used by the software when setting up a new Voice Type user.
This is a proprietary, legacy support-file format belonging to IBM Voice Type rather than a general-purpose document format. It is normally used internally by the Windows software and is not intended for direct editing.
Open an M2I file on Microsoft Windows with IBM Voice Type. The file is a support file, so Voice Type normally opens it automatically when required rather than through a separate file viewer.
Do not expect a standard text or media application to display its contents correctly.
M2I files are internal IBM Voice Type support files and have no standard conversion format. They should remain with the associated Voice Type installation.
