EasyConverter Express – No MP3 Output When Using 22kb Voices

Overview

Some users may find that EasyConverter Express does not generate any MP3 output when converting from Microsoft Word to MP3 while using a 22kb text‑to‑speech voice. This issue affects all conversions performed with these older voice types.

This article explains why the issue occurs and provides recommended alternatives to ensure successful MP3 generation.

Cause of the Issue

The problem occurs because 22kb voices are legacy voices that are now considered deprecated. These older voices are no longer fully supported by modern Windows audio and speech frameworks, which prevents EasyConverter Express from producing MP3 output when they are selected.

As a result, conversions using a 22kb voice may:

• Produce no MP3 file

• Fail silently without an error message

• Complete the conversion process but output nothing

Recommended Solution

To ensure successful MP3 generation, we recommend switching to Microsoft OneCore voices, which are:

• Free

• Modern and fully supported

• Installed by default on Windows 10 and Windows 11

• High‑quality and available in multiple languages

Installing Additional OneCore Voices

Users can download more OneCore voices directly through Windows Settings:

1. Open Settings

2. Go to Time & Language

3. Select Speech

4. Under Manage voices, choose Add voices

5. Select the desired language and voice package

Once installed, the new voices will appear in EasyConverter Express and can be used for MP3 output.

Current Status

There is no fix available for the deprecated 22kb voices, and they are unlikely to regain compatibility. Using Microsoft OneCore voices is the recommended long‑term solution.

This article will be updated if further guidance becomes available.
