ModelTalker

From the ModelTalker Voice Banking Service - Download your Personal Synthetic Voice - Use your voice as the system default TTS voice and with speech-enabled apps

ModelTalker utility app allows you to download and install your personal ModelTalker synthetic voice as an iOS system voice. Compatible with both iPhone and iPad, the app provides limited direct text to speech so you can enter phrases, sentences, or even whole paragraphs and have them spoken aloud in your own voice created with our online Voice Banking Service. Moreover, because your voice is installed as an iOS system voice, you can select your ModelTalker voice as the default system voice, and select it as you voice in AAC apps such as Predictable, Grid, Speech Assistant, TD Talk, and many others!

To get started after the app is installed, tap the Voice bar at the top of the page. In the Voices page, tap Add in the upper right and log in with your ModelTalker username and password. After your voice finished downloading, tap the bar containing your name to select it then use the Back button to return to the main screen where you can enter text and have it spoken in your voice.
