Question

I am a developer. I would like to develop a natural voice for Windows narrator. Is this possible? How? User should be able to install my voice in settings UI:

What is the difference between natural voices and legacy voices?

Answer 1

Developing a custom voice for Windows Narrator is possible.

You'll need to create a high-quality voice using Text-to-Speech (TTS) technology.

Your voice needs to be compatible with SAPI 5 to work with Narrator.

You can use the Microsoft Speech Platform SDK to develop your voice.

Package your voice as a SAPI 5 compliant voice pack.

Create an installer that places your voice files in the correct Windows directories.

The installer should also add appropriate registry entries to make the voice discoverable by Windows.

Your voice pack needs to be properly registered with the system.

The main difference is natural voices have significantly improved quality and naturalness, making them more pleasant to listen to for extended periods. Legacy voices, while less realistic, can be more reliable in terms of pronunciation consistency and often require less computational power.

Answer 2

Developing a custom voice for Windows Narrator is possible, but it requires some specific steps and considerations, like-Voice Creation, SAPI 5 Compliance, Voice Development, Packaging, Installation and UI integration.

Natural voices are more natural and realistic as well as more pleasant.
