Google Cloud 文字轉語音運算子¶

先決條件任務¶

若要使用這些運算子，您必須執行以下幾項操作

使用 Cloud Console 選擇或建立 Cloud Platform 專案。

為您的專案啟用計費功能，如 Google Cloud 文件所述。

啟用 API，如 Cloud Console 文件所述。
透過 pip 安裝 API 程式庫。
pip install 'apache-airflow[google]'
詳細資訊請參閱安裝。
設定 Google Cloud 連線.

CloudTextToSpeechSynthesizeOperator¶

將文字合成到音訊檔案並儲存至 Google Cloud Storage

如需參數定義，請參閱 CloudTextToSpeechSynthesizeOperator

引數¶

input、voice 和 audio_config 引數需要是字典或來自 google.cloud.texttospeech_v1.types 模組的對應類別的物件

tests/system/google/cloud/text_to_speech/example_text_to_speech.py[原始碼]

INPUT = {"text": "Sample text for demo purposes"}
VOICE = {"language_code": "en-US", "ssml_gender": "FEMALE"}
AUDIO_CONFIG = {"audio_encoding": "LINEAR16"}

filename 引數是一個簡單的字串引數

tests/system/google/cloud/text_to_speech/example_text_to_speech.py[原始碼]

FILENAME = "gcp-speech-test-file"

使用運算子¶

tests/system/google/cloud/text_to_speech/example_text_to_speech.py[原始碼]

text_to_speech_synthesize_task = CloudTextToSpeechSynthesizeOperator(
    input_data=INPUT,
    voice=VOICE,
    audio_config=AUDIO_CONFIG,
    target_bucket_name=BUCKET_NAME,
    target_filename=FILENAME,
    task_id="text_to_speech_synthesize_task",
)

範本¶

template_fields: Sequence[str] = (
    "input_data",
    "voice",
    "audio_config",
    "project_id",
    "gcp_conn_id",
    "target_bucket_name",
    "target_filename",
    "impersonation_chain",
)
