Speech Framework 只能识别英语吗？

Question

我目前正在从事一个关于语音识别和使用 WebAPI 翻译成另一种语言的项目。 English to Any Language 已经完成，但我想用其他语言进行此识别。

Speech Framework只能识别英文吗？我可以将此框架用于其他语言吗？

感谢您的帮助！

Answer 1

Does Speech Framework recognize only English?

不，它没有，如Apple Speech Recognition API Session中所述 (02:55):

"iOS 10 supports over 50 languages and dialects ..."

此外，改编自 Speech Framework Documentation：

The Speech APIs perform speech recognition by communicating with Apple's servers or using an on-device speech recognizer, if available. To find out if a speech recognizer is available for a specific language, you adopt the SFSpeechRecognizerDelegate protocol.

SFSpeechRecognizerDelegate 协议只包含一个可选方法：

speechRecognizer(_:availabilityDidChange:):

Tells the delegate when the availability of the speech recognizer has changed.

您可以将 - 例如 - 实施为：

func speechRecognizer(_ speechRecognizer: SFSpeechRecognizer, availabilityDidChange available: Bool) {
    if available {
        // you could display is as enabled in the app
    } else {
        // you could display is as disabled in the app
    }
}

实现此方法的实际目的是跟踪可用性变化，如果语音识别可用，available 将设置为 true。

试试这个：

SFSpeechRecognizer(locale: Locale.init(identifier: "vi"))

identifier 是您要使用的语言。语言指示符示例：

//English : en
//French : fr
//Japanese : ja
//VietNamese : vi

只要运行print(SFSpeechRecognizer.supportedLocales())你就会得到

[es-419 (fixed), th-TH (fixed), ca-ES (fixed), fr-BE (fixed), de-CH (fixed), sk-SK (fixed), en-ZA (fixed), es-CL (fixed), hi-IN (fixed), zh-CN (fixed), zh-TW (fixed), da-DK (fixed), hi-IN-translit (fixed), el-GR (fixed), he-IL (fixed), pt-BR (fixed), en-AE (fixed), pt-PT (fixed), fr-CH (fixed), ro-RO (fixed), vi-VN (fixed), en-SA (fixed), pl-PL (fixed), es-US (fixed), hi-Latn (fixed), en-SG (fixed), tr-TR (fixed), hr-HR (fixed), ko-KR (fixed), uk-UA (fixed), it-CH (fixed), ar-SA (fixed), id-ID (fixed), en-IN (fixed), es-ES (fixed), de-AT (fixed), en-IE (fixed), cs-CZ (fixed), es-CO (fixed), zh-HK (fixed), sv-SE (fixed), en-PH (fixed), en-ID (fixed), en-CA (fixed), nl-NL (fixed), yue-CN (fixed), en-NZ (fixed), en-GB (fixed), ja-JP (fixed), it-IT (fixed), ru-RU (fixed), en-US (fixed), ms-MY (fixed), es-MX (fixed), hu-HU (fixed), fr-CA (fixed), wuu-CN (fixed), de-DE (fixed), fr-FR (fixed), fi-FI (fixed), nb-NO (fixed), nl-BE (fixed), en-AU (fixed)]

Answer 4

我花了几个小时寻找一种解决方案，以便以人类可读的形式获取所有受支持的语言，这对我很有效。首先，为一种语言创建一个模型：

struct SupportedLanguage {
    let code: String?
    let name: String?
}

接下来运行 SFSpeechRecognizer.supportedLocales() 中的“for”循环，创建 SupportedLanguage 个实例并将它们添加到数组 availableLanguages:

var availableLanguages: [SupportedLanguage] = []
for locale in SFSpeechRecognizer.supportedLocales() {
    let language = SupportedLanguage (
        code: locale.languageCode,
        name: Locale.init(identifier: "en").localizedString(forIdentifier: locale.identifier)
    )
    availableLanguages.append(language)
}

仅此而已 - 对于每种语音框架支持的语言，您都有一个 SupportedLanguage 实例数组。语言选择工作很顺利。

Answer 5

//Usage for Locales
SFSpeechRecognizer(locale: Locale.init(identifier: "vi"))

//list to get all supported Locales
SFSpeechRecognizer.supportedLocales()
