快速入門：建立即時自動分段標記

文章
10/16/2024

參考文件 | 套件 (NuGet) | GitHub 上的其他範例

在本快速入門中，您會使用即時自動分段標記來執行語音轉換文字謄寫的應用程式。自動分段標記針對參與交談的不同說話者進行區分。語音服務提供有關哪位說話者正在講出所謄寫語音之特定部分的資訊。

說話者資訊包含在說話者識別碼欄位內的結果中。說話者識別碼是服務在所提供的音訊內容中識別不同說話者時指派給每位交談參與者的通用識別碼。

提示

您可以在 Speech Studio 中嘗試即時語音轉換文字，而不需要註冊或撰寫任何程式碼。不過，Speech Studio 尚不支援自動分段標記。

必要條件

Azure 訂用帳戶。您可以免費建立一個訂用帳戶。
在 Azure 入口網站上建立語音資源。
取得語音資源金鑰和區域。部署語音資源之後，選取 [移至資源] 以檢視和管理索引鍵。

設定環境

語音 SDK 可以 NuGet 套件的形式取得，並且實作 .NET Standard 2.0。您會在本指南的後續部分中安裝語音 SDK，但請先參閱 SDK 安裝指南，了解其他需求。

設定環境變數

您必須驗證應用程式以存取 Azure AI 服務。本文說明如何使用環境變數來儲存您的認證。然後，您可以從程式碼存取環境變數，以驗證您的應用程式。針對實際執行環境，使用更安全的方法來儲存和存取您的認證。

重要

我們建議使用適用於 Azure 資源的受控識別搭配 Microsoft Entra ID 驗證，以避免使用在雲端執行的應用程式儲存認證。

如果您使用 API 金鑰，請將其安全地儲存在別處，例如 Azure Key Vault。請勿在程式碼中直接包含 API 金鑰，且切勿公開張貼金鑰。

如需 AI 服務安全性的詳細資訊，請參閱驗證對 Azure AI 服務的要求。

若要設定語音資源索引鍵和區域的環境變數，請開啟主控台視窗，並遵循作業系統和開發環境的指示進行。

若要設定 SPEECH_KEY 環境變數，請以您其中一個資源金鑰取代 your-key。
若要設定 SPEECH_REGION 環境變數，請以您的其中一個資源區域取代 your-region。

setx SPEECH_KEY your-key
setx SPEECH_REGION your-region

注意

如果您只需要存取目前主控台的環境變數，您可以使用 set (而不是 setx) 來設定環境變數。

新增環境變數之後，您可能需要重新啟動任何需要讀取環境變數的程式，包括主控台視窗。例如，如果正在使用 Visual Studio 作為編輯器，請您在執行範例前重新啟動 Visual Studio。

Bash

編輯 .bashrc 檔案，然後新增環境變數:

export SPEECH_KEY=your-key
export SPEECH_REGION=your-region

新增環境變數之後，請從主控台視窗執行 source ~/.bashrc，讓變更生效。

Bash

編輯 .bash_profile 檔案，然後新增環境變數:

export SPEECH_KEY=your-key
export SPEECH_REGION=your-region

新增環境變數之後，請從主控台視窗執行 source ~/.bash_profile，讓變更生效。

Xcode

如果是 iOS 或 macOS 開發，請在 Xcode 中設定環境變數。例如，遵循下列步驟，在 Xcode 13.4.1 中設定環境變數。

選取 [產品] > [配置] > [編輯配置]。
在 [執行] (偵錯執行) 頁面上，選取 [引數]。
在 [環境變數] 下，選取加號 (+) 新增環境變數。
針對 [名稱] 輸入 SPEECH_KEY，然後針對 [值] 輸入您的語音資源索引碼。

若要設定語音資源區域的環境變數，請遵循相同的步驟。將 SPEECH_REGION 設為資源的區域。例如： westus 。

如需更多設定選項，請參閱 Xcode 文件。

使用交談謄寫從檔案實作自動分段標記

遵循下列步驟來建立主控台應用程式並安裝語音 SDK。

在資料夾開啟要新增專案的命令提示字元視窗。執行此命令以使用 .NET CLI 建立主控台應用程式。
```
dotnet new console
```
此命令會在您的專案目錄中建立 Program.cs 檔案。

使用 .NET CLI 在新專案中安裝語音 SDK。

dotnet add package Microsoft.CognitiveServices.Speech

以下列程式碼取代 Program.cs 的內容。

using Microsoft.CognitiveServices.Speech;
using Microsoft.CognitiveServices.Speech.Audio;
using Microsoft.CognitiveServices.Speech.Transcription;

class Program 
{
    // This example requires environment variables named "SPEECH_KEY" and "SPEECH_REGION"
    static string speechKey = Environment.GetEnvironmentVariable("SPEECH_KEY");
    static string speechRegion = Environment.GetEnvironmentVariable("SPEECH_REGION");

    async static Task Main(string[] args)
    {
        var filepath = "katiesteve.wav";
        var speechConfig = SpeechConfig.FromSubscription(speechKey, speechRegion);        
        speechConfig.SpeechRecognitionLanguage = "en-US";
        speechConfig.SetProperty(PropertyId.SpeechServiceResponse_DiarizeIntermediateResults, "true"); 

        var stopRecognition = new TaskCompletionSource<int>(TaskCreationOptions.RunContinuationsAsynchronously);

        // Create an audio stream from a wav file or from the default microphone
        using (var audioConfig = AudioConfig.FromWavFileInput(filepath))
        {
            // Create a conversation transcriber using audio stream input
            using (var conversationTranscriber = new ConversationTranscriber(speechConfig, audioConfig))
            {
                conversationTranscriber.Transcribing += (s, e) =>
                {
                    Console.WriteLine($"TRANSCRIBING: Text={e.Result.Text} Speaker ID={e.Result.SpeakerId}");
                };

                conversationTranscriber.Transcribed += (s, e) =>
                {
                    if (e.Result.Reason == ResultReason.RecognizedSpeech)
                    {
                        Console.WriteLine();
                        Console.WriteLine($"TRANSCRIBED: Text={e.Result.Text} Speaker ID={e.Result.SpeakerId}");
                        Console.WriteLine();
                    }
                    else if (e.Result.Reason == ResultReason.NoMatch)
                    {
                        Console.WriteLine($"NOMATCH: Speech could not be transcribed.");
                    }
                };

                conversationTranscriber.Canceled += (s, e) =>
                {
                    Console.WriteLine($"CANCELED: Reason={e.Reason}");

                    if (e.Reason == CancellationReason.Error)
                    {
                        Console.WriteLine($"CANCELED: ErrorCode={e.ErrorCode}");
                        Console.WriteLine($"CANCELED: ErrorDetails={e.ErrorDetails}");
                        Console.WriteLine($"CANCELED: Did you set the speech resource key and region values?");
                        stopRecognition.TrySetResult(0);
                    }

                    stopRecognition.TrySetResult(0);
                };

                conversationTranscriber.SessionStopped += (s, e) =>
                {
                    Console.WriteLine("\n    Session stopped event.");
                    stopRecognition.TrySetResult(0);
                };

                await conversationTranscriber.StartTranscribingAsync();

                // Waits for completion. Use Task.WaitAny to keep the task rooted.
                Task.WaitAny(new[] { stopRecognition.Task });

                await conversationTranscriber.StopTranscribingAsync();
            }
        }
    }
}

取得範例音訊檔案 (英文) 或使用您自己的 .wav 檔案。將 katiesteve.wav 取代為您 .wav 檔案的路徑和名稱。

應用程式會辨識交談中多個參與者的語音。您的音訊檔案應該包含多個說話者。
若要變更語音辨識語言，請以另一種支援的語言取代 en-US。例如，es-ES 代表西班牙文 (西班牙)。如果您未指定語言，則預設語言為 en-US。如需詳細了解如何識別所可能說出的多種語言之一，請參閱語言識別。
執行主控台應用程式以開始交談謄寫：
```
dotnet run
```

重要

確保您已設定 SPEECH_KEY 和 SPEECH_REGION 環境變數。如果您未設定這些變數，則範例會失敗，並顯示錯誤訊息。

謄寫的交談應輸出為文字：

根據交談中的說話者數目，說話者會被識別為 Guest-1、Guest-2 等等。

注意

當尚未識別說話者時，您可能會在一些早期中繼結果中看到 Speaker ID=Unknown。若沒有中繼的自動分段標記結果 (如果您未將 PropertyId.SpeechServiceResponse_DiarizeIntermediateResults 屬性設定為 “true”)，則說話者識別碼一律為 “Unknown”。

清除資源

您可以使用 Azure 入口網站或 Azure 命令列介面 (CLI) 來移除您所建立的語音資源。

參考文件 | 套件 (NuGet) | GitHub 上的其他範例

說話者資訊包含在說話者識別碼欄位內的結果中。說話者識別碼是服務在所提供的音訊內容中識別不同說話者時指派給每位交談參與者的通用識別碼。

提示

您可以在 Speech Studio 中嘗試即時語音轉換文字，而不需要註冊或撰寫任何程式碼。不過，Speech Studio 尚不支援自動分段標記。

必要條件

Azure 訂用帳戶。您可以免費建立一個訂用帳戶。
在 Azure 入口網站上建立語音資源。
取得語音資源金鑰和區域。部署語音資源之後，選取 [移至資源] 以檢視和管理索引鍵。

設定環境

語音 SDK 可以 NuGet 套件的形式取得，並且實作 .NET Standard 2.0。您會在本指南的後續部分中安裝語音 SDK，但請先參閱 SDK 安裝指南，了解其他需求。

設定環境變數

重要

我們建議使用適用於 Azure 資源的受控識別搭配 Microsoft Entra ID 驗證，以避免使用在雲端執行的應用程式儲存認證。

如果您使用 API 金鑰，請將其安全地儲存在別處，例如 Azure Key Vault。請勿在程式碼中直接包含 API 金鑰，且切勿公開張貼金鑰。

如需 AI 服務安全性的詳細資訊，請參閱驗證對 Azure AI 服務的要求。

若要設定語音資源索引鍵和區域的環境變數，請開啟主控台視窗，並遵循作業系統和開發環境的指示進行。

若要設定 SPEECH_KEY 環境變數，請以您其中一個資源金鑰取代 your-key。
若要設定 SPEECH_REGION 環境變數，請以您的其中一個資源區域取代 your-region。

setx SPEECH_KEY your-key
setx SPEECH_REGION your-region

注意

如果您只需要存取目前主控台的環境變數，您可以使用 set (而不是 setx) 來設定環境變數。

Bash

編輯 .bashrc 檔案，然後新增環境變數:

export SPEECH_KEY=your-key
export SPEECH_REGION=your-region

新增環境變數之後，請從主控台視窗執行 source ~/.bashrc，讓變更生效。

Bash

編輯 .bash_profile 檔案，然後新增環境變數:

export SPEECH_KEY=your-key
export SPEECH_REGION=your-region

新增環境變數之後，請從主控台視窗執行 source ~/.bash_profile，讓變更生效。

Xcode

如果是 iOS 或 macOS 開發，請在 Xcode 中設定環境變數。例如，遵循下列步驟，在 Xcode 13.4.1 中設定環境變數。

選取 [產品] > [配置] > [編輯配置]。
在 [執行] (偵錯執行) 頁面上，選取 [引數]。
在 [環境變數] 下，選取加號 (+) 新增環境變數。
針對 [名稱] 輸入 SPEECH_KEY，然後針對 [值] 輸入您的語音資源索引碼。

若要設定語音資源區域的環境變數，請遵循相同的步驟。將 SPEECH_REGION 設為資源的區域。例如： westus 。

如需更多設定選項，請參閱 Xcode 文件。

使用交談謄寫從檔案實作自動分段標記

遵循下列步驟來建立主控台應用程式並安裝語音 SDK。

在 Visual Studio Community 2022 中建立名為 ConversationTranscription 的新 C++ 主控台專案。
選取 [工具]>[Nuget 套件管理員]>[套件管理員主控台]。在套件管理員主控台中，執行此命令。

取得範例音訊檔案 (英文) 或使用您自己的 .wav 檔案。將 katiesteve.wav 取代為您 .wav 檔案的路徑和名稱。

應用程式會辨識交談中多個參與者的語音。您的音訊檔案應該包含多個說話者。
若要變更語音辨識語言，請以另一種支援的語言取代 en-US。例如，es-ES 代表西班牙文 (西班牙)。如果您未指定語言，則預設語言為 en-US。如需詳細了解如何識別所可能說出的多種語言之一，請參閱語言識別。
執行並執行您的應用程式，以開始交談謄寫：

重要

確保您已設定 SPEECH_KEY 和 SPEECH_REGION 環境變數。如果您未設定這些變數，則範例會失敗，並顯示錯誤訊息。

謄寫的交談應輸出為文字：

根據交談中的說話者數目，說話者會被識別為 Guest-1、Guest-2 等等。

注意

當尚未識別說話者時，您可能會在一些早期中繼結果中看到 Speaker ID=Unknown。若沒有中繼的自動分段標記結果 (如果您未將 PropertyId::SpeechServiceResponse_DiarizeIntermediateResults 屬性設定為 “true”)，則說話者識別碼一律為 “Unknown”。

清除資源

您可以使用 Azure 入口網站或 Azure 命令列介面 (CLI) 來移除您所建立的語音資源。

參考文件 | 套件 (Go) | GitHub 上的其他範例

適用於 Go 程式設計語言的語音 SDK 不支援交談轉譯。請選取其他程式設計語言，或本文開頭的 Go 參考和樣本連結。

參考文件 | GitHub 上的其他範例

說話者資訊包含在說話者識別碼欄位內的結果中。說話者識別碼是服務在所提供的音訊內容中識別不同說話者時指派給每位交談參與者的通用識別碼。

提示

您可以在 Speech Studio 中嘗試即時語音轉換文字，而不需要註冊或撰寫任何程式碼。不過，Speech Studio 尚不支援自動分段標記。

必要條件

Azure 訂用帳戶。您可以免費建立一個訂用帳戶。
在 Azure 入口網站上建立語音資源。
取得語音資源金鑰和區域。部署語音資源之後，選取 [移至資源] 以檢視和管理索引鍵。

設定環境

若要設定環境，請安裝語音 SDK。本快速入門中的範例適用於 JAVA 執行階段。

安裝 Apache Maven。然後執行 mvn -v 以確認安裝成功。

在專案的根目錄中建立新 pom.xml 檔案，並將下列內容複製到其中：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        </dependency>
    </dependencies>
</project>

安裝語音 SDK 和相依性。
```
mvn clean dependency:copy-dependencies
```

設定環境變數

重要

我們建議使用適用於 Azure 資源的受控識別搭配 Microsoft Entra ID 驗證，以避免使用在雲端執行的應用程式儲存認證。

如果您使用 API 金鑰，請將其安全地儲存在別處，例如 Azure Key Vault。請勿在程式碼中直接包含 API 金鑰，且切勿公開張貼金鑰。

如需 AI 服務安全性的詳細資訊，請參閱驗證對 Azure AI 服務的要求。

若要設定語音資源索引鍵和區域的環境變數，請開啟主控台視窗，並遵循作業系統和開發環境的指示進行。

若要設定 SPEECH_KEY 環境變數，請以您其中一個資源金鑰取代 your-key。
若要設定 SPEECH_REGION 環境變數，請以您的其中一個資源區域取代 your-region。

setx SPEECH_KEY your-key
setx SPEECH_REGION your-region

注意

如果您只需要存取目前主控台的環境變數，您可以使用 set (而不是 setx) 來設定環境變數。

Bash

編輯 .bashrc 檔案，然後新增環境變數:

export SPEECH_KEY=your-key
export SPEECH_REGION=your-region

新增環境變數之後，請從主控台視窗執行 source ~/.bashrc，讓變更生效。

Bash

編輯 .bash_profile 檔案，然後新增環境變數:

export SPEECH_KEY=your-key
export SPEECH_REGION=your-region

新增環境變數之後，請從主控台視窗執行 source ~/.bash_profile，讓變更生效。

Xcode

如果是 iOS 或 macOS 開發，請在 Xcode 中設定環境變數。例如，遵循下列步驟，在 Xcode 13.4.1 中設定環境變數。

選取 [產品] > [配置] > [編輯配置]。
在 [執行] (偵錯執行) 頁面上，選取 [引數]。
在 [環境變數] 下，選取加號 (+) 新增環境變數。
針對 [名稱] 輸入 SPEECH_KEY，然後針對 [值] 輸入您的語音資源索引碼。

若要設定語音資源區域的環境變數，請遵循相同的步驟。將 SPEECH_REGION 設為資源的區域。例如： westus 。

如需更多設定選項，請參閱 Xcode 文件。

使用交談謄寫從檔案實作自動分段標記

遵循下列步驟來建立主控台應用程式進行交談謄寫。

在相同的專案根目錄中建立名為 ConversationTranscription.java 的新檔案。

將下列程式碼複製到 ConversationTranscription.java：

import com.microsoft.cognitiveservices.speech.*;
import com.microsoft.cognitiveservices.speech.audio.AudioConfig;
import com.microsoft.cognitiveservices.speech.transcription.*;

import java.util.concurrent.Semaphore;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.Future;

public class ConversationTranscription {
    // This example requires environment variables named "SPEECH_KEY" and "SPEECH_REGION"
    private static String speechKey = System.getenv("SPEECH_KEY");
    private static String speechRegion = System.getenv("SPEECH_REGION");

    public static void main(String[] args) throws InterruptedException, ExecutionException {

        SpeechConfig speechConfig = SpeechConfig.fromSubscription(speechKey, speechRegion);
        speechConfig.setSpeechRecognitionLanguage("en-US");
        AudioConfig audioInput = AudioConfig.fromWavFileInput("katiesteve.wav");
        speechConfig.setProperty(PropertyId.SpeechServiceResponse_DiarizeIntermediateResults, "true");

        Semaphore stopRecognitionSemaphore = new Semaphore(0);

        ConversationTranscriber conversationTranscriber = new ConversationTranscriber(speechConfig, audioInput);
        {
            // Subscribes to events.
            conversationTranscriber.transcribing.addEventListener((s, e) -> {
                System.out.println("TRANSCRIBING: Text=" + e.getResult().getText() + " Speaker ID=" + e.getResult().getSpeakerId() );
            });

            conversationTranscriber.transcribed.addEventListener((s, e) -> {
                if (e.getResult().getReason() == ResultReason.RecognizedSpeech) {
                    System.out.println();
                    System.out.println("TRANSCRIBED: Text=" + e.getResult().getText() + " Speaker ID=" + e.getResult().getSpeakerId() );
                    System.out.println();
                }
                else if (e.getResult().getReason() == ResultReason.NoMatch) {
                    System.out.println("NOMATCH: Speech could not be transcribed.");
                }
            });

            conversationTranscriber.canceled.addEventListener((s, e) -> {
                System.out.println("CANCELED: Reason=" + e.getReason());

                if (e.getReason() == CancellationReason.Error) {
                    System.out.println("CANCELED: ErrorCode=" + e.getErrorCode());
                    System.out.println("CANCELED: ErrorDetails=" + e.getErrorDetails());
                    System.out.println("CANCELED: Did you update the subscription info?");
                }

                stopRecognitionSemaphore.release();
            });

            conversationTranscriber.sessionStarted.addEventListener((s, e) -> {
                System.out.println("\n    Session started event.");
            });

            conversationTranscriber.sessionStopped.addEventListener((s, e) -> {
                System.out.println("\n    Session stopped event.");
            });

            conversationTranscriber.startTranscribingAsync().get();

            // Waits for completion.
            stopRecognitionSemaphore.acquire();

            conversationTranscriber.stopTranscribingAsync().get();
        }

        speechConfig.close();
        audioInput.close();
        conversationTranscriber.close();

        System.exit(0);
    }
}

取得範例音訊檔案 (英文) 或使用您自己的 .wav 檔案。將 katiesteve.wav 取代為您 .wav 檔案的路徑和名稱。

應用程式會辨識交談中多個參與者的語音。您的音訊檔案應該包含多個說話者。
若要變更語音辨識語言，請以另一種支援的語言取代 en-US。例如，es-ES 代表西班牙文 (西班牙)。如果您未指定語言，則預設語言為 en-US。如需詳細了解如何識別所可能說出的多種語言之一，請參閱語言識別。

執行新的主控台應用程式，以開始交談謄寫：

javac ConversationTranscription.java -cp ".;target\dependency\*"
java -cp ".;target\dependency\*" ConversationTranscription

重要

確保您已設定 SPEECH_KEY 和 SPEECH_REGION 環境變數。如果您未設定這些變數，則範例會失敗，並顯示錯誤訊息。

謄寫的交談應輸出為文字：

取得範例音訊檔案 (英文) 或使用您自己的 .wav 檔案。將 katiesteve.wav 取代為您 .wav 檔案的路徑和名稱。

應用程式會辨識交談中多個參與者的語音。您的音訊檔案應該包含多個說話者。
若要變更語音辨識語言，請以另一種支援的語言取代 en-US。例如，es-ES 代表西班牙文 (西班牙)。如果您未指定語言，則預設語言為 en-US。如需詳細了解如何識別所可能說出的多種語言之一，請參閱語言識別。
執行新的主控台應用程式，以從檔案啟動語音辨識：
```
node.exe ConversationTranscription.js
```

重要

確保您已設定 SPEECH_KEY 和 SPEECH_REGION 環境變數。如果您未設定這些變數，則範例會失敗，並顯示錯誤訊息。

謄寫的交談應輸出為文字：

SessionStarted event
SessionId:E87AFBA483C2481985F6C9AF719F616B
TRANSCRIBED: Text=Good morning, Steve. Speaker ID=Unknown
TRANSCRIBED: Text=Good morning, Katie. Speaker ID=Unknown
TRANSCRIBED: Text=Have you tried the latest real time diarization in Microsoft Speech Service which can tell you who said what in real time? Speaker ID=Guest-1
TRANSCRIBED: Text=Not yet. I've been using the batch transcription with diarization functionality, but it produces diarization result until whole audio get processed. Speaker ID=Guest-2
TRANSCRIBED: Text=Is the new feature can diarize in real time? Speaker ID=Guest-2
TRANSCRIBED: Text=Absolutely. Speaker ID=Guest-1
TRANSCRIBED: Text=That's exciting. Let me try it right now. Speaker ID=Guest-2
Canceled event
undefined
SessionStopped event
SessionId:E87AFBA483C2481985F6C9AF719F616B

根據交談中的說話者數目，說話者會被識別為 Guest-1、Guest-2 等等。

清除資源

您可以使用 Azure 入口網站或 Azure 命令列介面 (CLI) 來移除您所建立的語音資源。

參考文件 | 套件 (下載) | GitHub 上的其他範例

適用於 Objective-C 的語音 SDK 支援交談謄寫，但目前尚未提供相對應的指南。請選取另一種程式設計語言來開始使用並了解概念，或參閱本文開頭連結的 Objective-C 參考和範例。

參考文件 | 套件 (下載) | GitHub 上的其他範例

適用於 Swift-C 的語音 SDK 支援交談謄寫，但目前尚未提供相對應的指南。請選取另一種程式設計語言來開始使用並了解概念，或參閱本文開頭連結的 Swift 參考和範例。

參考文件 | 套件 (PyPi) | GitHub 上的其他範例

說話者資訊包含在說話者識別碼欄位內的結果中。說話者識別碼是服務在所提供的音訊內容中識別不同說話者時指派給每位交談參與者的通用識別碼。

提示

您可以在 Speech Studio 中嘗試即時語音轉換文字，而不需要註冊或撰寫任何程式碼。不過，Speech Studio 尚不支援自動分段標記。

必要條件

Azure 訂用帳戶。您可以免費建立一個訂用帳戶。
在 Azure 入口網站上建立語音資源。
取得語音資源金鑰和區域。部署語音資源之後，選取 [移至資源] 以檢視和管理索引鍵。

設定環境

適用於 Python 的語音 SDK 會以 Python 套件索引 (PyPI) 模組的形式提供。適用於 Python 的語音 SDK 與 Windows、Linux 和 macOS 相容。

請為平台安裝適用於 Visual Studio 2015、2017、2019 和 2022 的 Microsoft Visual C++ 可轉散發套件。第一次安裝此套件時可能需要重新啟動。
在 Linux 上，您必須使用 x64 目標架構。

安裝 Python 從 3.7 或更新的版本。請先檢查 SDK 安裝指南以了解更多需求。

設定環境變數

重要

我們建議使用適用於 Azure 資源的受控識別搭配 Microsoft Entra ID 驗證，以避免使用在雲端執行的應用程式儲存認證。

如果您使用 API 金鑰，請將其安全地儲存在別處，例如 Azure Key Vault。請勿在程式碼中直接包含 API 金鑰，且切勿公開張貼金鑰。

如需 AI 服務安全性的詳細資訊，請參閱驗證對 Azure AI 服務的要求。

若要設定語音資源索引鍵和區域的環境變數，請開啟主控台視窗，並遵循作業系統和開發環境的指示進行。

若要設定 SPEECH_KEY 環境變數，請以您其中一個資源金鑰取代 your-key。
若要設定 SPEECH_REGION 環境變數，請以您的其中一個資源區域取代 your-region。

setx SPEECH_KEY your-key
setx SPEECH_REGION your-region

注意

如果您只需要存取目前主控台的環境變數，您可以使用 set (而不是 setx) 來設定環境變數。

Bash

編輯 .bashrc 檔案，然後新增環境變數:

export SPEECH_KEY=your-key
export SPEECH_REGION=your-region

新增環境變數之後，請從主控台視窗執行 source ~/.bashrc，讓變更生效。

Bash

編輯 .bash_profile 檔案，然後新增環境變數:

export SPEECH_KEY=your-key
export SPEECH_REGION=your-region

新增環境變數之後，請從主控台視窗執行 source ~/.bash_profile，讓變更生效。

Xcode

如果是 iOS 或 macOS 開發，請在 Xcode 中設定環境變數。例如，遵循下列步驟，在 Xcode 13.4.1 中設定環境變數。

選取 [產品] > [配置] > [編輯配置]。
在 [執行] (偵錯執行) 頁面上，選取 [引數]。
在 [環境變數] 下，選取加號 (+) 新增環境變數。
針對 [名稱] 輸入 SPEECH_KEY，然後針對 [值] 輸入您的語音資源索引碼。

若要設定語音資源區域的環境變數，請遵循相同的步驟。將 SPEECH_REGION 設為資源的區域。例如： westus 。

如需更多設定選項，請參閱 Xcode 文件。

使用交談謄寫從檔案實作自動分段標記

請遵循下列步驟以建立新的主控台應用程式。

開啟要新增專案的命令提示字元視窗，然後建立名為 conversation_transcription.py 的新檔案。

執行此命令以安裝語音 SDK：

pip install azure-cognitiveservices-speech

將下列程式碼複製到 conversation_transcription.py：

    conversation_transcriber.canceled.connect(conversation_transcriber_recognition_canceled_cb)
    # stop transcribing on either session stopped or canceled events
    conversation_transcriber.session_stopped.connect(stop_cb)
    conversation_transcriber.canceled.connect(stop_cb)

    conversation_transcriber.start_transcribing_async()

    # Waits for completion.
    while not transcribing_stop:
        time.sleep(.5)

    conversation_transcriber.stop_transcribing_async()

# Main
