AVSpeechSynthesizer getting long in the tooth

I'm wondering if we can expect an enhancement in the text to speech functionality anytime soon. AVSpeechSynthesizer is a little outdated compared to many speech synthesizers nowadays that are more natural and can distinguish between acronyms and words. It would be an awesome upgrade that it seems Apple could do very well. Thanks.
