I found a similar issue that might help you resolve the "TTS is not enabled" error. The error typically indicates that the Text-to-Speech (TTS) feature is not activated in your application's configuration. To resolve this, ensure that the TTS feature is enabled in your configuration file. Here's a general approach:

1. Check your application's configuration file and look for the text_to_speech section.

2. Ensure that the enabled key is set to True. Your configuration should look something like this:

   config = {
       "text_to_speech": {
           "enabled": True,
           "voice": "default_voice",  # Optional: specify the voice
           "language": "en"           # Optional: specify the language
       }
   }

Additionally, if you are using OpenAI TTS, make sure that FFmpeg is installed on your system, as it is required for the TTS functionality to work properly ^[1][2].

@dosu This can only be used during an HTTP call. The current issue lies in the configuration.

To resolve this, ensure that the TTS feature is enabled in your configuration file. Here's a general approach:我發現了一個類似的問題，可能有助於你解決「TTS 未啟用」錯誤。這個錯誤通常表示你的應用程式配置中未啟用文字轉語音（TTS）功能。要解決這個問題，請確保在你的配置檔案中啟用 TTS 功能。以下是一般的做法：

1. Check your application's configuration file and look for the `text_to_speech` section.檢查您的應用程式的配置檔案，並尋找 `text_to_speech` 區段。

2. Ensure that the `enabled` key is set to `True`. Your configuration should look something like this:確保 `enabled` 鍵被設置為 `True` 。您的配置應該看起來像這樣：
   ```python
   config = {
       "text_to_speech": {
           "enabled": True,
           "voice": "default_voice",  # Optional: specify the voice
           "language": "en"           # Optional: specify the language
       }
   }
   ```

Additionally, if you are using OpenAI TTS, make sure that FFmpeg is installed on your system, as it is required for the TTS functionality to work properly [1][2].此外，如果您正在使用 OpenAI TTS，請確保您的系統上已安裝 FFmpeg ，因為這是 TTS 功能正常運作所需的 [1] [2] 。

To resolve the "TTS is not enabled" error during an HTTP call, ensure that the Text-to-Speech (TTS) feature is enabled in your application's configuration. Specifically, check the following:

1. If your application is in ADVANCED_CHAT or WORKFLOW mode, make sure the workflow object is not None and that features_dict contains the key "text_to_speech" with "enabled" set to True.

2. If your application is not in these modes, verify that the text_to_speech_dict in app_model.app_model_config has "enabled" set to True ^[1][2].

Additionally, ensure that your configuration dictionary is correctly structured, with the text_to_speech key as a dictionary containing the enabled field set to a boolean value. If the configuration is missing or incorrectly formatted, the validate_and_set_defaults method will set defaults that may disable TTS ^[2].
