We have just released the latest version (1.7.0) of Voice4u TTS on the App Store. Finally we’ve enabled the feature of changing a gender of voices.

Voice4u TTS currently supports 52 types of voices in 37 languages. The following languages have gender options:
English (UK)
English (UK)
English (Australia)
Chinese (Simplified)
French
German
Japanese

This feature requires iOS 10 or later. When the automatic language detection options is ON, the app tries to select a voice in your gender preference.

Here is how it works:

Selecting a voice manually

Navigate: “Settings” > “Languages“. Then tap on a language that you want to use.

You also need to slide OFF the “Language Detection” switch. Otherwise, the app will override your selection.

Let the app select a voice (Automatic)

Open the Setting screen, and slide ON the “Language Detection” switch. Then select your gender preference in “Gender of Voice“.

If you see any glitch of the app, OR if you have any suggestions / feature requests, feel free to contact us anytime.

Thank you!
— Voice4u team

P.S.
Voice4u TTS is available on the App Store.
