列出所有支持的语音

您可以通过调用 API 的 voices:list 端点来获取所有受支持语音的完整列表。您还可以在支持的语音页面上找到前述列表。

以下代码段演示如何列出 Text-to-Speech API 中提供的可用于文本转语音合成的语音。

这些示例要求您已安装并初始化 Google Cloud CLI。如需了解如何设置 gcloud CLI，请参阅向 TTS 进行身份验证。

协议

如需了解完整的详细信息，请参阅 voices:list API 端点。

要获取文本转语音合成的可用语音列表，请向 voices:list API 端点发出 GET 请求。 将 PROJECT_ID 替换为您的项目 ID。

curl -H "Authorization: Bearer $(gcloud auth print-access-token)" \
    -H "x-goog-user-project: PROJECT_ID" \
    -H "Content-Type: application/json; charset=utf-8" \
    "https://texttospeech.googleapis.com/v1/voices"

Text-to-Speech API 返回与以下内容类似的 JSON 格式的结果：

{
  "voices": [
    {
      "languageCodes": [
        "es-ES"
      ],
      "name": "es-ES-Standard-A",
      "ssmlGender": "FEMALE",
      "naturalSampleRateHertz": 24000
    },
    {
      "languageCodes": [
        "ja-JP"
      ],
      "name": "ja-JP-Standard-A",
      "ssmlGender": "FEMALE",
      "naturalSampleRateHertz": 22050
    },
    {
      "languageCodes": [
        "pt-BR"
      ],
      "name": "pt-BR-Standard-A",
      "ssmlGender": "FEMALE",
      "naturalSampleRateHertz": 24000
    },
        ...
  ]
}
