How can you synthesize speech using Phonemes for iOS

I'm working on an application that requires the use of a text to speech synthesizer. Implementing this was rather simple for iOS using AVSpeechSynthesizer. However, when it comes to customizing synthesis, I was directed to documentation about speech synthesis for an OSX only API, which allows you to input phoneme pairs, in order to customize word pronunciation. Unfortunately, this interface is not available on iOS.

I was hoping someone might know of a similar library or plugin that might accomplish the same task. If you do, it would be much appreciated if you would lend a hand.

Thanks in advance!

  • AVSpeechSynthesizer for iOS is not capable (out of the box) to work with phonemes. NSSpeechSynthesizer is capable of it, but that's not available on iOS.

    You can create an algorithm that produces short phonemes, but it would be incredibly difficult to make it sound good by any means.
