Swift 数字名称文本到 Int

Question

我刚刚实现了 SFSpeechRecognizer，因为我希望它指定一些数字，但我遇到的问题是，如果我说“一”，则 result.bestTranscription.formattedString 是“一”，但如果我说“十”，结果抛出“10”，我怎样才能设法得到由实际数字而不是交响乐“一”表示的个位数数字。

You can use NumberFormatter setting numberStyle to .spellOut and use its number(from: String) to convert your string to number. If you need a string from that number just initialise a new string from it. Make sure if you only want to detect English words (not locale sensitive) to set the formatter locale to "en_US_POSIX"

let string = "one"
let numberFormatter = NumberFormatter()
numberFormatter.locale = Locale(identifier: "en_US_POSIX")  // if you dont set locale it will use current locale so it wont detect one if the language it is not english at the devices locale
numberFormatter.numberStyle = .spellOut
numberFormatter.number(from: string)   // 1

Testing another language/locale

let string = "um"
let numberFormatter = NumberFormatter()
numberFormatter.locale = Locale(identifier: "pt_BR")
numberFormatter.numberStyle = .spellOut
numberFormatter.number(from: string)   // 1
