Could you build this?
Partial The iOS EPUB reader wrapper is straightforward, but running high-quality neural text-to-speech models locally on mobile devices requires CoreML quantization and specialized ML inference optimization.
What it would actually take: The app needs a Swift/SwiftUI reader engine using an EPUB parsing framework, paired with an embedded on-device neural TTS engine (such as Piper, Kokoro, or FastSpeech converted to Core ML). The challenging part is optimizing model weights (INT8/FP16) to execute efficiently on Apple Neural Engine without overheating, draining battery, or stuttering during real-time streaming audio generation. Deep familiarity with Core ML, audio graph rendering (AVAudioEngine), and on-device machine learning inference is required.
