问题描述

目前我使用默认的 iOS 语音到文本转换，而没有为其添加任何代码.当用户说五"时，显示为五"或5".但是，我需要始终将其转换为5".我可以使用 SFSpeechRecognizer 或任何其他方式来实现这一目标吗?

Currently I'm using default iOS speech to text conversion without adding any code for it. When the user says 'five', it is displayed as 'five' or '5'. But, I need it to be converted as '5' always. Is there anything I can do with SFSpeechRecognizer or any other way to achieve this?

推荐答案

这可以帮助您入门，但它无法处理包含数字和非数字的混合字符串.理想情况下，您需要在每个单词出现时对其进行处理，但这会对组合数字(例如 34)产生潜在影响.

This can get you started, but it is not able to handle mixed strings that contain a number AND a non-number. Ideally, you would need to process each word as it comes through, but then that has potential effects for combined numbers (thirty four) for example.

let fiveString = "five"
let numberFormatter = NumberFormatter()
numberFormatter.numberStyle = .spellOut

print(numberFormatter.number(from: fiveString)?.stringValue) // 5

let combinedString = "five dogs"
print(numberFormatter.number(from: combinedString)?.stringValue) // nil

let cString = "five hundred"
print(numberFormatter.number(from: cString)?.stringValue) // 500

let dString = "five hundred and thirty-seven"
print(numberFormatter.number(from: dString)?.stringValue) // 537
