Custom Voice 빠른 시작

시작하기 전에

  1. Custom Voice 기능에 액세스하기 위해 Google에 GCP 프로젝트 ID를 제공했습니다. 결제를 사용 설정하고, Text-to-Speech API 및 AutoML API를 사용 설정하고, 이 프로젝트에 대한 인증을 설정했는지 확인합니다.

  2. 커스텀 음성을 합성하는 데 사용할 서비스 계정에 AutoML 예측자 역할을 할당합니다. 자세한 내용은 IAM 역할 및 서비스 계정에 대한 Google Cloud 문서를 참조하세요.

명령줄 사용

HTTP 메서드 및 URL:

POST https://texttospeech.googleapis.com/v1beta1/text:synthesize

JSON 요청 본문:

{
  "input":{
    "text":"Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets."
  },
  "voice":{
    "custom_voice":{
      "reportedUsage":"REALTIME",
      "model":"projects/{project_id}/locations/us-central1/models/{model_id}"
     }
  },
  "audioConfig":{
    "audioEncoding":"LINEAR16"
  }
}

요청 본문을 request.json 파일에 저장하고 다음 명령어를 실행합니다.
