XCode 11.4.1. Run on simulators (iOS 13.4.1)If we write this code for speech (Swift), 'willSpeakRangeOfSpeechString' delegate method will return a wrong character rangelet speechSynthesizer = AVSpeechSynthesizer() let speechUtterance = AVSpeechUtterance(string: "VIA, .\nNeedless to say, 2020 is off to an unprecedented start.") speechUtterance.voice = AVSpeechSynthesisVoice(language: "en-US") speechUtterance.rate = 0.40 speechUtterance.pitchMultiplier = 0.50 speechUtterance.volume = 0.75 speechSynthesizer.speak(speechUtterance)willSpeakRangeOfSpeechString is wrong when the speaker says "2020".Here below I list character range and word referenced each time:character range: {0, 3} -> 'VIA' character range: {3, 1} -> ',' character range: {5, 1} -> '.' character range: {7, 8} -> 'Needless' character range: {16, 2} -> 'to' character range: {19, 4} -> 'say,' character range: {47, 4} -> 'cede' // ERROR: instead of 2020 it send back wrong character range character range: {29, 2} -> 'is' character range: {32, 3} -> 'off' character range: {36, 2} -> 'to' character range: {39, 2} -> 'an' character range: {42, 13} -> 'unprecedented' character range: {56, 6} -> 'start.'Interesting to note that if we change voice language, character range sent back is correct.speechUtterance.voice = AVSpeechSynthesisVoice(language: "it-IT")Is it a bug on speech framework on simulators?Thanks
