Mulai cepat: Percakapan multi-perangkat

Artikel
02/24/2024

Dalam mulai cepat ini, Anda akan mempelajari cara menggunakan SDK Ucapan untuk membuat percakapan multiperangkat baru dengan dukungan terjemahan, serta bergabung dalam percakapan yang sudah ada.

Catatan

Speech SDK untuk Java, JavaScript, Objective-C, dan Swift mendukung percakapan multi-perangkat, tetapi kami belum menyertakan panduan di sini.

Anda dapat melihat atau mengunduh semua Sampel C# SDK Ucapan di GitHub.

Prasyarat

Sebelum memulai, pastikan untuk:

Menambahkan sampel kode

Buka Program.cs, dan ganti semua kode di dalamnya dengan kode berikut:

using Microsoft.CognitiveServices.Speech;
using Microsoft.CognitiveServices.Speech.Audio;
using Microsoft.CognitiveServices.Speech.Transcription;
using System;
using System.Threading.Tasks;

namespace HelloWorld

            string region = "YourServiceRegion";

            // Sets source and target languages.
            // Replace with the languages of your choice, from list found here: https://aka.ms/speech/sttt-languages
            string fromLanguage = "en-US";
            string toLanguage = "de";

Di file yang sama, ganti string YourSubscriptionKey dengan kunci langganan Cognitive Speech Anda.
Ganti string YourServiceRegion dengan wilayah yang terkait dengan langganan Anda.
Dari bilah menu, pilih File>Simpan Semua.

Membuat dan menjalankan aplikasi untuk membuat percakapan baru

Dari bilah menu, pilih Buat>Buat Solution untuk membuat aplikasi. Kode harus dikompilasi tanpa kesalahan sekarang.
Pilih Debug>Mulai Penelusuran Kesalahan (atau tekan F5) untuk memulai aplikasi helloworld.
Setelah melihat pesan Started transcribing muncul, Anda dapat mulai berbicara. Anda akan melihat transkripsi muncul saat berbicara.
- Jika Anda berbagi kode percakapan dengan yang lain dan mereka bergabung dalam percakapan, Anda juga akan melihat transkripsi mereka.
Setelah selesai berbicara, tekan Ctrl+C untuk menghentikan penangkapan audio, dan mengakhiri percakapan.

Membuat dan menjalankan aplikasi untuk bergabung dalam percakapan yang sudah ada

Salin dan tempel fungsi berikut ke dalam Program.cs Anda:

static async Task JoinConversationAsync(string conversationId)
{
    // Set this to the display name you want for the participant
    string displayName = "participant";

    // Set the speech to text, or text language you want to use
    string language = "en-US";

    // Create the task completion source that will be used to wait until the user presses Ctrl + c
    var completionSource = new TaskCompletionSource<bool>();

    // Register to listen for Ctrl+C
    Console.CancelKeyPress += (s, e) =>
    {
        completionSource.TrySetResult(true);
        e.Cancel = true; // don't terminate the current process
    };

    // As a participant, you don't need to specify any subscription key, or region. You can directly create
    // the conversation translator object
    var audioConfig = AudioConfig.FromDefaultMicrophoneInput();
    using (var conversationTranslator = new ConversationTranslator(audioConfig))
    {
        // Register for any events you are interested here. For now let's just register for
        // transcription, and instant message events
        conversationTranslator.TextMessageReceived += (s, e) =>
        {
            Console.WriteLine($"Received an instant message from '{e.Result.ParticipantId}': '{e.Result.Text}'");
            foreach (var entry in e.Result.Translations)
            {
                Console.WriteLine($"\tTranslated into '{entry.Key}': '{entry.Value}'");
            }
        };
        conversationTranslator.Transcribed += (s, e) =>
        {
            Console.WriteLine($"Received a transcription from '{e.Result.ParticipantId}': '{e.Result.Text}'");
            foreach (var entry in e.Result.Translations)
            {
                Console.WriteLine($"\tTranslated into '{entry.Key}': '{entry.Value}'");
            }
        };
        conversationTranslator.Transcribing += (s, e) =>
        {
            Console.WriteLine($"Received a partial transcription from '{e.Result.ParticipantId}': '{e.Result.Text}'");
            foreach (var entry in e.Result.Translations)
            {
                Console.WriteLine($"\tTranslated into '{entry.Key}': '{entry.Value}'");
            }
        };

        // To start receiving events, you will need to join the conversation
        await conversationTranslator.JoinConversationAsync(conversationId, displayName, language).ConfigureAwait(false);

        // You can now send an instant message
        await conversationTranslator.SendTextMessageAsync("Message from participant").ConfigureAwait(false);

        // Start capturing audio if you specified a speech to text language
        await conversationTranslator.StartTranscribingAsync().ConfigureAwait(false);
        Console.WriteLine("Started transcribing. Press Ctrl-C to stop");

        // At this point, you should start receiving transcriptions for what you are saying using
        // the default microphone. Press Ctrl+C to stop audio capture
        await completionSource.Task.ConfigureAwait(false);

        // Stop audio capture
        await conversationTranslator.StopTranscribingAsync().ConfigureAwait(false);

        // Leave the conversation. You will stop receiving events after this
        await conversationTranslator.LeaveConversationAsync().ConfigureAwait(false);
    }
}

Ganti CreateConversationAsync(); di fungsi public static async Task Main(string[] args) Anda dengan:
```
// Set this to the conversation you want to join
JoinConversationAsync("YourConversationId");
```

Anda harus membuat percakapan yang bisa Anda ikuti:
1. Buka browser Anda dan buka: https://translator.microsoft.com.
2. Pilih "Mulai percakapan".
3. Masuk menggunakan salah satu opsi yang tersedia.
4. Ketikkan nama (misalnya Host).
5. Pilih bahasa (misalnya bahasa Inggris).
6. Pilih tombol Enter.
7. Perhatikan kode percakapan di bagian atas halaman.
Tip

Jika Anda menggunakan tombol salin di halaman web, pastikan Anda menghapus translate.it/ di awal. Anda hanya memerlukan ID percakapan 5 karakter (misalnya: ABCDE).

Kembali ke Visual Studio dan ganti string YourConversationId dengan ID percakapan yang Anda buat di langkah sebelumnya.
Dari bilah menu, pilih Buat>Buat Solution untuk membuat aplikasi. Kode harus dikompilasi tanpa kesalahan sekarang.
Pilih Debug>Mulai Penelusuran Kesalahan (atau tekan F5) untuk memulai aplikasi helloworld.
Setelah melihat pesan Started transcribing muncul, Anda dapat mulai berbicara. Anda akan melihat transkripsi muncul saat berbicara.
- Jika kembali ke browser Anda, Anda akan melihat transkripsi muncul di sana saat Anda berbicara juga.
Setelah selesai berbicara, tekan Ctrl+C untuk menghentikan penangkapan audio, dan mengakhiri percakapan.
Kembali ke browser Anda dan keluar dari percakapan menggunakan tombol keluar di pojok kanan atas.

Membuat dan menjalankan aplikasi untuk membuat percakapan baru

Dari bilah menu, pilih Buat>Buat Solution untuk membuat aplikasi. Kode harus dikompilasi tanpa kesalahan sekarang.
Pilih Debug>Mulai Penelusuran Kesalahan (atau tekan F5) untuk memulai aplikasi helloworld.
Setelah melihat pesan Started transcribing muncul, Anda dapat mulai berbicara. Anda akan melihat transkripsi muncul saat Anda berbicara
- Jika Anda berbagi kode percakapan dengan yang lain dan mereka bergabung dalam percakapan, Anda juga akan melihat transkripsi mereka.
Setelah selesai berbicara, tekan Ctrl+C di keyboard Anda untuk menghentikan tangkapan audio.

Catatan

Anda mungkin melihat pesan dari Visual Studio tentang pengecualian yang mirip dengan: Exception thrown at 0x76EB90BF (KernelBase.dll) in helloworld.exe: 0x40010005: Control-C. Anda dapat mengabaikan ini.

Tekan F5 untuk melanjutkan.

Membuat dan menjalankan aplikasi untuk bergabung dalam percakapan yang sudah ada

Salin dan tempel fungsi berikut ke helloworld.cpp tepat sebelum fungsi int main():

void JoinExistingConversation(const std::string& conversationId)
{
    std::string speechLanguage("en-US");

    // You'll now need to create a ConversationTranslator to send audio, send IMs, and receive conversation events
    auto audioConfig = AudioConfig::FromDefaultMicrophoneInput();
    auto conversationTranslator = ConversationTranslator::FromConfig(audioConfig);

    // Attach event handlers here. For example:
    conversationTranslator->Transcribing += [](const ConversationTranslationEventArgs& args)
    {
        std::cout << "Received a partial transcription from " << args.Result->ParticipantId << ": " << args.Result->Text << std::endl;
        for (const auto& entry : args.Result->Translations)
        {
            std::cout << "\t" << entry.first << ": " << entry.second << std::endl;
        }
    };
    conversationTranslator->Transcribed += [](const ConversationTranslationEventArgs& args)
    {
        std::cout << "Received a transcription from " << args.Result->ParticipantId << ": " << args.Result->Text << std::endl;
        for (const auto& entry : args.Result->Translations)
        {
            std::cout << "\t" << entry.first << ": " << entry.second << std::endl;
        }
    };
    conversationTranslator->TextMessageReceived += [](const ConversationTranslationEventArgs& args)
    {
        std::cout << "Received an instant message from " << args.Result->ParticipantId << ": " << args.Result->Text << std::endl;
        for (const auto& entry : args.Result->Translations)
        {
            std::cout << "\t" << entry.first << ": " << entry.second << std::endl;
        }
    };

    // Join the conversation
    conversationTranslator->JoinConversationAsync(conversationId, "participant", speechLanguage).get();

    // Start sending audio
    conversationTranslator->StartTranscribingAsync().get();
    std::cout << "Started transcribing. Press Ctrl + C to stop" << std::endl;
    future.get(); // wait for Ctrl - C to be pressed

    // Stop audio capture
    conversationTranslator->StopTranscribingAsync().get();

    // Once you are done, leave the conversation
    conversationTranslator->LeaveConversationAsync().get();
}

Ganti StartNewConversation(); di fungsi int main() Anda dengan:

// Set this to the conversation you want to join
JoinExistingConversation("YourConversationId");

Anda harus membuat percakapan yang bisa Anda ikuti:
1. Buka browser Anda dan buka: https://translator.microsoft.com.
2. Pilih "Mulai percakapan".
3. Masuk menggunakan salah satu opsi yang tersedia.
4. Ketikkan nama (misalnya Host).
5. Pilih bahasa (misalnya bahasa Inggris).
6. Pilih tombol Enter.
7. Perhatikan kode percakapan di bagian atas halaman.
Tip

Jika Anda menggunakan tombol salin di halaman web, pastikan Anda menghapus translate.it/ di awal. Anda hanya memerlukan ID percakapan 5 karakter (misalnya: ABCDE).

Kembali ke Visual Studio dan ganti YourConversationId di fungsi int main() Anda dengan ID percakapan dari langkah sebelumnya.
Dari bilah menu, pilih Buat>Buat Solution untuk membuat aplikasi. Kode harus dikompilasi tanpa kesalahan.
Pilih Debug>Mulai Penelusuran Kesalahan (atau tekan F5) untuk memulai aplikasi helloworld.
Setelah melihat pesan Started transcribing muncul, Anda dapat mulai berbicara. Anda akan melihat transkripsi muncul saat berbicara.
- Jika kembali ke browser Anda, Anda akan melihat transkripsi muncul di sana saat Anda berbicara juga.
Setelah selesai berbicara, tekan Ctrl+C untuk menghentikan penangkapan audio, dan mengakhiri percakapan.

Tekan F5 untuk melanjutkan.
Kembali ke browser Anda dan keluar dari percakapan menggunakan tombol keluar di pojok kanan atas.
