Pengenal

Speech-to-Text V2 mendukung resource Google Cloud yang disebut pengenal (recognizer). Pengenal merepresentasikan konfigurasi pengenalan yang tersimpan dan dapat digunakan kembali. Anda dapat menggunakannya untuk mengelompokkan transkripsi atau traffic secara logis untuk aplikasi Anda.

Sebelum memulai

  1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
  2. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

    Go to project selector

  3. Make sure that billing is enabled for your Google Cloud project.

  4. Enable the Speech-to-Text APIs.

    Enable the APIs

  5. Make sure that you have the following role or roles on the project: Cloud Speech Administrator

    Check for the roles

    1. In the Google Cloud console, go to the IAM page.

      Go to IAM
    2. Select the project.
    3. In the Principal column, find all rows that identify you or a group that you're included in. To learn which groups you're included in, contact your administrator.

    4. For all rows that specify or include you, check the Role colunn to see whether the list of roles includes the required roles.

    Grant the roles

    1. In the Google Cloud console, go to the IAM page.

      Buka IAM
    2. Pilih project.
    3. Klik Berikan akses.
    4. Di kolom New principals, masukkan ID pengguna Anda. Ini biasanya adalah alamat email untuk Akun Google.

    5. Di daftar Pilih peran, pilih peran.
    6. Untuk memberikan peran tambahan, klik Tambahkan peran lain, lalu tambahkan setiap peran tambahan.
    7. Klik Simpan.
    8. Install the Google Cloud CLI.
    9. To initialize the gcloud CLI, run the following command:

      gcloud init
    10. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

      Go to project selector

      10. Library klien dapat menggunakan Kredensial Default Aplikasi untuk dengan mudah melakukan autentikasi dengan Google API dan mengirim permintaan ke API tersebut. Dengan Kredensial Default Aplikasi, Anda dapat menguji aplikasi secara lokal dan men-deploy aplikasi tanpa mengubah kode yang mendasarinya. Untuk informasi selengkapnya, lihat Lakukan autentikasi untuk menggunakan library klien.

      11. If you're using a local shell, then create local authentication credentials for your user account:

        gcloud auth application-default login

        You don't need to do this if you're using Cloud Shell.

      Selain itu, pastikan Anda telah menginstal library klien.

      Memahami pengenal

      Pengenal adalah konfigurasi pengenalan yang dapat dikonfigurasi dan dapat digunakan kembali. Membuat pengenal dengan konfigurasi pengenalan yang sering digunakan akan membantu menyederhanakan dan mengurangi ukuran permintaan pengenalan.

      Elemen inti pengenal adalah konfigurasi default-nya. Ini adalah konfigurasi untuk setiap permintaan pengenalan yang dilakukan pengenal ini. Anda dapat mengganti nilai default ini per permintaan. Pertahankan konfigurasi default untuk fitur yang Anda perlukan di seluruh permintaan untuk pengenal tertentu, sekaligus ganti fitur spesifik untuk permintaan tertentu.

      Gunakan kembali pengenal sesering mungkin. Membuat satu pengenal untuk setiap permintaan akan meningkatkan latensi aplikasi secara drastis dan menghabiskan kuota resource Anda. Buat pengenal sesekali saja selama integrasi dan penyiapan, lalu gunakan kembali untuk permintaan pengenalan.

      Membuat pengenal

      Berikut adalah contoh cara membuat pengenal yang dapat digunakan untuk mengirim permintaan pengenalan:

      Python

      import os
      
      from google.cloud.speech_v2 import SpeechClient
      from google.cloud.speech_v2.types import cloud_speech
      
      PROJECT_ID = os.getenv("GOOGLE_CLOUD_PROJECT")
      
      
      def create_recognizer(recognizer_id: str) -> cloud_speech.Recognizer:
          """Сreates a recognizer with an unique ID and default recognition configuration.
          Args:
              recognizer_id (str): The unique identifier for the recognizer to be created.
          Returns:
              cloud_speech.Recognizer: The created recognizer object with configuration.
          """
          # Instantiates a client
          client = SpeechClient()
      
          request = cloud_speech.CreateRecognizerRequest(
              parent=f"projects/{PROJECT_ID}/locations/global",
              recognizer_id=recognizer_id,
              recognizer=cloud_speech.Recognizer(
                  default_recognition_config=cloud_speech.RecognitionConfig(
                      language_codes=["en-US"], model="long"
                  ),
              ),
          )
          # Sends the request to create a recognizer and waits for the operation to complete
          operation = client.create_recognizer(request=request)
          recognizer = operation.result()
      
          print("Created Recognizer:", recognizer.name)
          return recognizer
      
      

      Menggunakan pengenal yang ada untuk mengirim permintaan

      Berikut adalah contoh cara mengirim beberapa permintaan pengenalan menggunakan pengenal yang sama:

      Python

      import os
      
      from google.cloud.speech_v2 import SpeechClient
      from google.cloud.speech_v2.types import cloud_speech
      
      PROJECT_ID = os.getenv("GOOGLE_CLOUD_PROJECT")
      
      
      def transcribe_reuse_recognizer(
          audio_file: str,
          recognizer_id: str,
      ) -> cloud_speech.RecognizeResponse:
          """Transcribe an audio file using an existing recognizer.
          Args:
              audio_file (str): Path to the local audio file to be transcribed.
                  Example: "resources/audio.wav"
              recognizer_id (str): The ID of the existing recognizer to be used for transcription.
          Returns:
              cloud_speech.RecognizeResponse: The response containing the transcription results.
          """
          # Instantiates a client
          client = SpeechClient()
      
          # Reads a file as bytes
          with open(audio_file, "rb") as f:
              audio_content = f.read()
      
          request = cloud_speech.RecognizeRequest(
              recognizer=f"projects/{PROJECT_ID}/locations/global/recognizers/{recognizer_id}",
              content=audio_content,
          )
      
          # Transcribes the audio into text
          response = client.recognize(request=request)
      
          for result in response.results:
              print(f"Transcript: {result.alternatives[0].transcript}")
      
          return response
      
      

      Mengaktifkan fitur di pengenal

      Pengenal dapat digunakan untuk mengaktifkan berbagai fitur dalam pengenalan, seperti tanda baca otomatis atau pemfilteran kata-kata tidak sopan.

      Berikut adalah contoh cara mengaktifkan tanda baca otomatis dalam sebuah pengenal yang mengaktifkan tanda baca otomatis dalam permintaan pengenalan menggunakan pengenal ini:

      Python

      # PROJECT_ID = "your-project-id"
      # recognizer_id = "id-recognizer"
      recognizer_name = (
          f"projects/{PROJECT_ID}/locations/global/recognizers/{recognizer_id}"
      )
      try:
          # Use an existing recognizer
          recognizer = client.get_recognizer(name=recognizer_name)
          print("Using existing Recognizer:", recognizer.name)
      except NotFound:
          # Create a new recognizer
          request = cloud_speech.CreateRecognizerRequest(
              parent=f"projects/{PROJECT_ID}/locations/global",
              recognizer_id=recognizer_id,

                      language_codes=["en-US"],
                      model="latest_long",
                      features=cloud_speech.RecognitionFeatures(
                          enable_automatic_punctuation=True,
                      ),
                  ),
              ),
          )
          operation = client.create_recognizer(request=request)
          recognizer = operation.result()
          print("Created Recognizer:", recognizer.name)
      
      # Reads a file as bytes
      with open(audio_file, "rb") as f:
          audio_content = f.read()
      
      request = cloud_speech.RecognizeRequest(
          recognizer=f"projects/{PROJECT_ID}/locations/global/recognizers/{recognizer_id}",
          content=audio_content,
      )
