언어 식별 구현

2025-05-25

언어 식별은 지원되는 언어 목록과 비교할 때 오디오에서 말하는 언어를 식별하는 데 사용됩니다.

언어 식별(LID) 사용 사례는 다음과 같습니다.

음성 텍스트 변환 인식 - 오디오 원본의 언어를 식별한 후 텍스트로 전사해야 하는 경우.
음성 번역 오디오 원본의 언어를 식별한 후 다른 언어로 번역해야 하는 경우

음성 인식의 경우 언어 식별에서 초기 대기 시간이 더 길어집니다. 이 선택적 기능은 필요한 경우에만 포함해야 합니다.

구성 옵션 설정

음성 텍스트 변환 또는 음성 번역에서 언어 식별을 사용하는지 여부에 관계없이 몇 가지 일반적인 개념과 구성 옵션이 있습니다.

오디오에 필요한 후보 언어 목록을 정의합니다.
시작 시 또는 연속 언어 식별을 사용할지 여부를 결정합니다.

그런 다음, 한 번 인식 또는 연속 인식을 Speech Service에 요청합니다.

이 문서에서는 개념을 설명하는 코드 조각을 제공합니다. 각 사용 사례에 대한 전체 샘플에 대한 링크가 제공됩니다.

후보 언어

AutoDetectSourceLanguageConfig 개체를 사용하여 후보 언어를 제공합니다. 하나 이상의 후보가 오디오에 있는 것으로 예상합니다. 시작 시 LID에 대해 최대 4개 언어를 포함하거나 연속 LID에 대해 최대 10개 언어를 포함할 수 있습니다. Speech Service는 후보 언어가 오디오에 없는 경우에도 제공된 해당 언어 중 하나를 반환합니다. 예를 들어 fr-FR(프랑스어) 및 en-US(영어)가 후보로 제공되었지만 독일어를 말하는 경우 서비스에서 fr-FR 또는 en-US가 반환됩니다.

대시(-) 구분 기호가 있는 전체 로캘을 제공해야 하지만 언어 식별은 기본 언어당 하나의 로캘만 사용합니다. 동일한 언어에 대해 여러 로캘(예: en-US 및 en-GB)을 포함하지 마세요.

var autoDetectSourceLanguageConfig =
    AutoDetectSourceLanguageConfig.FromLanguages(new string[] { "en-US", "de-DE", "zh-CN" });

auto autoDetectSourceLanguageConfig = 
    AutoDetectSourceLanguageConfig::FromLanguages({ "en-US", "de-DE", "zh-CN" });

auto_detect_source_language_config = \
    speechsdk.languageconfig.AutoDetectSourceLanguageConfig(languages=["en-US", "de-DE", "zh-CN"])

AutoDetectSourceLanguageConfig autoDetectSourceLanguageConfig =
    AutoDetectSourceLanguageConfig.fromLanguages(Arrays.asList("en-US", "de-DE", "zh-CN"));

var autoDetectSourceLanguageConfig = SpeechSDK.AutoDetectSourceLanguageConfig.fromLanguages([("en-US", "de-DE", "zh-CN"]);

NSArray *languages = @[@"en-US", @"de-DE", @"zh-CN"];
SPXAutoDetectSourceLanguageConfiguration* autoDetectSourceLanguageConfig = \
    [[SPXAutoDetectSourceLanguageConfiguration alloc]init:languages];

자세한 내용은 지원되는 언어를 참조하세요.

시작 시 및 연속 언어 식별

음성은 시작 시 및 연속 LID(언어 식별)를 모두 지원합니다.

참고 항목

연속 언어 식별은 C#, C++, Java(음성 텍스트 변환만 해당), JavaScript(음성 텍스트 변환만 해당) 및 Python의 Speech SDK에서만 지원됩니다.

시작 시 LID는 언어를 오디오의 처음 몇 초 내에 한 번 식별합니다. 오디오의 언어가 변경되지 않는 경우 시작 시 LID를 사용합니다. 시작 시 LID를 사용하면 단일 언어가 검색되고 5초 이내에 반환됩니다.
연속 LID는 오디오 중에 여러 언어를 식별할 수 있습니다. 오디오의 언어가 변경될 수 있는 경우 연속 LID를 사용합니다. 연속 LID는 동일한 문장 내에서 언어 변경을 지원하지 않습니다. 예를 들어 스페인어를 주로 말하고 몇몇 영어 단어를 삽입하는 경우 단어당 언어 변경이 검색되지 않습니다.

한 번 인식 또는 연속 인식 메서드를 호출하여 시작 시 LID 또는 연속 LID를 구현합니다. 연속 LID는 연속 인식에서만 지원됩니다.

한 번 또는 연속 인식

언어 식별은 인식 개체 및 작업을 사용하여 완료됩니다. 오디오 인식을 위해 Speech Service에 요청합니다.

참고 항목

인식과 식별을 혼동하지 마세요. 인식은 언어 식별의 사용 여부에 관계없이 사용할 수 있습니다.

“한 번 인식” 메서드를 호출하거나, 연속 인식 시작 및 중지 메서드를 호출합니다. 다음 중에서 선택합니다.

시작 시 LID를 사용하여 한 번 인식 연속 LID는 한 번 인식을 지원하지 않습니다.
시작 시 LID에서 연속 인식을 사용합니다.
연속 LID와 함께 연속 인식을 사용합니다.

SpeechServiceConnection_LanguageIdMode 속성은 연속 LID에만 필요합니다. 이 속성이 없으면 Speech Service가 기본적으로 시작 시 LID로 설정됩니다. 지원되는 값은 시작 시 LID에 대해 AtStart, 연속 LID의 경우 Continuous입니다.

// Recognize once with At-start LID. Continuous LID isn't supported for recognize once.
var result = await recognizer.RecognizeOnceAsync();

// Start and stop continuous recognition with At-start LID
await recognizer.StartContinuousRecognitionAsync();
await recognizer.StopContinuousRecognitionAsync();

// Start and stop continuous recognition with Continuous LID
speechConfig.SetProperty(PropertyId.SpeechServiceConnection_LanguageIdMode, "Continuous");
await recognizer.StartContinuousRecognitionAsync();
await recognizer.StopContinuousRecognitionAsync();

// Recognize once with At-start LID. Continuous LID isn't supported for recognize once.
auto result = recognizer->RecognizeOnceAsync().get();

// Start and stop continuous recognition with At-start LID
recognizer->StartContinuousRecognitionAsync().get();
recognizer->StopContinuousRecognitionAsync().get();

// Start and stop continuous recognition with Continuous LID
speechConfig->SetProperty(PropertyId::SpeechServiceConnection_LanguageIdMode, "Continuous");
recognizer->StartContinuousRecognitionAsync().get();
recognizer->StopContinuousRecognitionAsync().get();

// Recognize once with At-start LID. Continuous LID isn't supported for recognize once.
SpeechRecognitionResult  result = recognizer->RecognizeOnceAsync().get();

// Start and stop continuous recognition with At-start LID
recognizer.startContinuousRecognitionAsync().get();
recognizer.stopContinuousRecognitionAsync().get();

// Start and stop continuous recognition with Continuous LID
speechConfig.setProperty(PropertyId.SpeechServiceConnection_LanguageIdMode, "Continuous");
recognizer.startContinuousRecognitionAsync().get();
recognizer.stopContinuousRecognitionAsync().get();

# Recognize once with At-start LID. Continuous LID isn't supported for recognize once.
result = recognizer.recognize_once()

# Start and stop continuous recognition with At-start LID
recognizer.start_continuous_recognition()
recognizer.stop_continuous_recognition()

# Start and stop continuous recognition with Continuous LID
speech_config.set_property(property_id=speechsdk.PropertyId.SpeechServiceConnection_LanguageIdMode, value='Continuous')
recognizer.start_continuous_recognition()
recognizer.stop_continuous_recognition()

음성 텍스트 변환 사용

오디오 원본의 언어를 식별한 후 텍스트로 전사해야 하는 경우 음성 텍스트 변환 인식을 사용합니다. 자세한 내용은 음성 텍스트 변환 개요를 참조하세요.

참고 항목

시작 시 언어 식별을 사용하는 음성 텍스트 변환 인식은 C#, C++, Python, Java, JavaScript 및 Objective-C의 Speech SDK에서 지원됩니다. 연속 언어 식별을 사용하는 음성 텍스트 변환 인식은 C#, C++, Java, JavaScript 및 Python의 Speech SDK에서만 지원됩니다.

현재 지속적인 언어 식별을 사용하여 음성 텍스트로 인식하려면 코드 예제와 같이 엔드포인트에서 SpeechConfig를 만들어야 합니다.

음성 번역 실행

오디오 원본의 언어를 식별한 후 다른 언어로 번역해야 하는 경우 음성 번역을 사용합니다. 자세한 내용은 음성 번역 개요를 참조하세요.

참고 항목

언어 식별을 사용하는 음성 번역은 C#, C++, JavaScript, Python의 Speech SDK에서만 지원됩니다.

GitHub에서 언어 식별을 사용하는 음성 번역의 더 많은 예제를 참조하세요.

컨테이너 실행 및 사용

음성 컨테이너는 음성 SDK 및 음성 CLI를 통해 액세스되는 websocket 기반 쿼리 엔드포인트 API를 제공합니다. 기본적으로 음성 SDK 및 음성 CLI는 공개 음성 서비스를 사용합니다. 컨테이너를 사용하려면 초기화 메서드를 변경해야 합니다. 키 및 엔드포인트 대신 컨테이너 호스트 URL을 사용합니다.

컨테이너에서 언어 ID를 실행할 때 SourceLanguageRecognizer 또는 SpeechRecognizer 대신 TranslationRecognizer 개체를 사용하세요.

컨테이너에 대한 자세한 내용은 언어 식별 음성 컨테이너 방법 가이드를 참조하세요.

음성 텍스트 변환 일괄 처리 대화 내용 기록 구현

Batch 전사 REST API를 사용하여 언어를 식별하려면 Transcriptions - Submit 요청의 본문에서 languageIdentification 속성을 사용하세요.

경고

일괄 처리 대화 내용 기록은 기본 기준 모델에 대한 언어 식별만 지원합니다. 언어 식별 및 사용자 지정 모델 모두 대화 내용 기록 요청에 지정된 경우 이 서비스는 지정된 후보 언어의 기준 모델 사용에 기댑니다. 이로 인해 예기치 않은 인식 결과가 발생할 수 있습니다.

음성 텍스트 변환 시나리오에 언어 식별 및 사용자 지정 모델이 모두 필요한 경우 일괄 처리 대화 내용 기록 대신 실시간 음성 텍스트 변환을 사용합니다.

다음 예제에서는 4개의 후보 언어에서 languageIdentification 속성을 사용하는 방법을 보여 줍니다. 요청 속성에 대한 자세한 내용은 일괄 처리 대화 내용 기록 만들기를 참조하세요.
