Implement a function for breaking through mute of the speech synthesizer.

[Zandor300]

Description

Implement SpeechSynthesizing.forceSpeak(instruction:during:locale:) for breaking through mute of the speech synthesizer.

I am using the SystemSpeechSyntesizer for providing additional spoken instructions in my app, but want some important instructions to break through the mute toggle that is in the UI. The forceSpeak(..) function will bypass the mute check and proceed to speak the instruction regardless.

Implementation

I've made the forceSpeak(..) function optional to implement in the SpeechSynthesizing protocol since I do not have a proper implementation for MapboxSpeechSynthesizer. That instead uses volume of an AVAudioPlayer to mute instructions.

So when forceSpeak(..) isn't implemented, it forwards the call to the regular speak(..) function while using UnimplementedLogging.logUnimplemented(..) to log a warning in console.
