Important note: This App is not a text reader. This App is designed to provide text-to-speech for use by Apple's VoiceOver utility for the visually-impaired. However any text-reading App you have should be able to use the voices provided by RHVoice. The voices within the App are provided by different teams of developers, mostly visually-impaired themselves. The developers have tended to concentrated on their own languages, or those languages which are not supported on mobile phones. Some of the voices are provided with the financial support from sponsors, others require a small App Store subscription. Funds are used to pay the App's operating expenses. If your language is not available within RHVoice please understand the limited resources available, and the lengthy process of making new voices, and the effort needed to support new users in their own language.
